4 General Info Company Profile One thing has never changed and that is our commitment to providing ever-higher levels of quality, performance, deliverability, and value to our customers. Founded in 98 as a supplier of precision automotive piston rings, Smalley Steel Ring Company had many years of successful growth in an expanding marketplace. Having had a variety of products throughout the years, it wasn t until 96, when present ownership began the development of products in the wire forming industry. Spiral Retaining Rings and Wave Springs emerged and Smalley developed into a reputable manufacturer of precision rings, springs & wire forms. But one thing never changed from years back, and that is our commitment to providing ever-higher levels of quality, performance, deliverability, and value to our customers. Today, Smalley Steel Ring Company is a market leader in the industrial retaining ring and wave/compression spring business; a position we work hard to maintain and build upon. Every Smalley ring and spring is engineered and manufactured to the highest quality standards using skills and processes we have honed over three quarters of a century. Our obsession with quality, combined with our near-perfect record of on-time delivery, has earned us an approved supplier status with leading OEM manufacturers around the world. Due to the ceaseless demands we place upon ourselves, Smalley has won the coveted title of Preferred Source in the most demanding applications: automotive, agriculture, aerospace, electronics, appliance, industrial, medical and power generation. While we are understandably proud of the recognition we have received, ultimately, it is our products that set us apart. Unlike stamped rings and springs, which are die-stamped through the metal grain, our edgewound rings and springs have a circumferential metal grain structure that gives them exceptional strength, dimensional stability, and predictable performance characteristics. Finally, every Smalley ring and spring is backed by our continued support. We are constantly searching ways to expand and improve our Customer Service and Engineering/Technical Assistance. We welcome your comments and your design challenges. Engineers are available to help assist with any design questions. With regional offices in Europe, we are prepared to service our European customers. Smalley provides customized global supply chain solutions, to meet your WORLDWIDE manufacturing requirements, in Europe, Asia Pacific and the America s. Please call us at or visit our website today!

5 General Info Products All of Smalley s wave springs and retaining rings are manufactured with our unique edgewinding manufacturing process. This eliminates any tooling charges, greatly increases design flexibility and reduces lead times as dies do not have to be produced. Retaining Rings Unlike die-stamped circlips / retaining rings, Spirolox Retaining Rings and Constant Section Rings are coiled on edge to the exact diameter required. They have a uniform cross-section (or to use our terminology, No Ears To Interfere within an assembly) and are free of burrs. Spirolox Retaining Rings meet military and aerospace specifications and are found in thousands of mechanical products around the world. Wave Springs Wave springs are precise flat wire compression springs that fit into assemblies that other springs cannot. Since the overall lengths and operating heights of wave springs are lower than those of conventional round wire springs, they will often reduce the size of an assembly by as much as 50%. Of course, this will also reduce the part weight and raw material cost of every spring produced. Manufactured in USA Smalley

6 General Info Raw Material As we meet the increasing demand for more raw material sizes, the flat wire rolling mill operation in our plant continues to grow. Years ago, Smalley began a vertical integration that has evolved into the production of hundreds of material cross-sections in a wide variety of alloys. Our goal to supply Smalley customers with uncompromising quality and service. 6 No-Tooling-Charges For Specials

7 General Info Manufacturing Edgewinding, also known as The No-Tooling-Cost Process, is our precision forming operation that coils pre-tempered flat wire on edge to create a near-perfect circle. (Visualize a Slinky, the coiled metal toy which has delighted generations of children.) Circular-Grain metallurgy gives our products strength and stability far superior to that of conventional retaining rings and wave washers which are simply stamped through the metal grain. Smalley edgewound products can be coiled to your exact specification in any diameter and with any number of turns (layers or coils), effectively eliminating material waste. As flexible as it is precise, our edgewinding process accommodates your design changes without the need for additional tooling and die modifications. This facilitates your developmental work, allowing us to produce your low-quantity custom orders and your working prototypes quickly and economically. Even after your initial prototype is produced, or in mid-stream production, our edgewinding process allows us to alter your design or dimensions with simple machine adjustments or a change in raw material size. After the revised specifications are approved, we complete and document the final setup. Then, we quickly resume production of your order, whether it consists of one part or one million. Edgewinding Process Conventional Stamping Process Prototypes About the easiest way to test a theoretical design is to produce a working prototype a task at which Smalley excels. A prime example is the development of a custom wave spring. We can adjust dimensions, by changing the number of waves and the number of turns, and trying different combinations of spring variables. Finally, we test for function, before production, so we know we have it right. Smalley-produced prototypes are also the most economical way to provide results on a trial-and-error basis. From one to a thousand pieces, we can produce, try, modify, and reproduce your design as often as necessary all without special tooling costs. Wire Flattening Manufactured in USA Smalley

11 General Info Quality Assurance Smalley s Total Quality Management philosophy dictates our commitment to quality and customer satisfaction. While this commitment has earned us official certification (ISO 900, ISO/TS 699, AS 900 and ISO 00), quality assurance and customer satisfaction mean much more at Smalley. They are tradition; the very foundation upon which we have built our company. From the beginning, we have never lost sight of our goal: to supply Smalley customers with uncompromising quality and service. Smalley is committed to a quality policy that requires conformance to specification with controlled lot variation about the target, statistical quality control, defect prevention, and annual improvement in process and product. This is a companywide commitment involving every Smalley employee. Each person works towards excellence, individually and cooperatively, to provide superior products and services. A history of quality and strict compliance with military and aerospace standards has earned Smalley an approved supplier status with many leading original equipment manufacturers worldwide. Smalley has worked diligently to become their Preferred Source for spiral retaining rings and wave springs. In accordance with the requirements of ISO 900, ISO/TS 699, AS 900 and ISO 00, we have established and are continuously improving our quality systems. Use of the latest technology, including statistical tools, has helped us achieve and maintain the world-class quality associated with the Smalley name for more than 0 years. Smalley uses statistical quality control tools to assure the capability and stability of our coiling process. To begin with, we identify common dimensions to monitor and special causes of variation in the product. Then, we collect and analyze data on these critical dimensions. We perform disciplined sampling and take measurements during in-line and final inspection, and yet again, during pre-shipping inspection. We make formal SQC in-house training programs mandatory for many Smalley employees involved with manufacturing. This training has noticeably developed quality awareness and responsibility at all levels. Our employees have a clear understanding of what is expected, a means of regulating their processes and checking their output, and statistical tools to determine when machine adjustments are required. Smalley s machine capability studies help us identify sources of variation before they become a problem. We analyze the capabilities of all production machinery in primary and secondary operations, heat treating, and finishing. In addition, we follow our own meticulous procedures to determine the reproducibility and repeatability of our gauging systems. Due to the careful documentation of our quality, many Smalley customers have found that they can reduce or even eliminate their incoming inspections of our product. Many of our accounts have also revised their policy of dual sourcing and confidently rely on Smalley as their single source of Spirolox Retaining Rings, wave springs, constant section rings, expanders and other wire forms. Defect prevention, or near-zero defects, is a key goal at Smalley. We use the latest automated inspection techniques to monitor production. As a result, we are constantly studying the causes of variation, improving upon and developing processes with capability indexes (Cpk) exceeding.. Continuous improvement is an integral part of Smalley s quality plan. We require each of our departments to design and implement projects to improve their respective systems.

12 Wave Spring Introduction All Springs Are Not Equal Smalley Wave Springs offer the unique advantage of space savings when used to replace coil springs. By reducing spring operating height, wave springs also produce a decrease in the spring cavity. With a smaller assembly size and less material used in the manufacturing process, a cost savings is realized. Wave springs operate as load bearing devices. They take up play and compensate for dimensional variations within assemblies. A virtually unlimited range of forces can be produced whereby loads build either gradually or abruptly to reach a predetermined working height. This establishes a precise spring rate in which load is proportional to deflection. Functional requirements are necessary for both dynamic and static spring applications. Special performance characteristics are individually built into each spring to satisfy a variety of precise operating conditions. Typically, a wave spring will occupy an extremely small area for the amount of work it performs. The use of this product is demanded, but not limited to tight axial and radial space constraints. Product Performance With their smooth, circular coiled sinusoidal wave form, and rolled round edges of pre-tempered raw material, Smalley s edgewound Wave Springs offer many advantages over die stamped products. Loads and spring rates are more accurate, more predictable, and may be toleranced better than 50 percent tighter than stampings. The force of a Smalley Wave Spring will increase at a uniform rate throughout most of its available deflection. By any criteria, Smalley Wave Springs offer their users higher dependability and better performance. Since they are produced from full hard, pre-tempered raw material, there is no risk of distorting the spring during a hardening heat treatment. By contrast, subsequent manufacturing procedures for stamped wavy washers can lead to problems such as fatigue cracking and inaccurate or inconsistent loading between springs. All told, the metallurgy, the mechanical properties and the uniform dimensional stability of the Smalley edgewound Wave Spring provide a component for precision quality applications.

13 Wave Spring Introduction Wave Spring Types Gap Type Wave Spring Overlap Type Wave Spring Gap & Overlap Type Conventional Gap and Overlap Type Wave Springs are used in a wide variety of applications. For short deflections and low-medium forces, they function with precision and dependability. These two types of Smalley Wave Springs permit radial expansion or growth in diameter within a cavity, without the binding or hang-up normally associated with die stamped wave washers. Just as their terms imply, the gap type is split to retain a gap between the ends, while the overlap type has overlapping ends. Thus, the ends are free to move circumferentially as the spring outside diameter grows during compression. For example, the O.D. of a Gap Type Wave Spring would fit.00 loose per side in a bore. Its I.D. clears a shaft by.00 per side. As the spring is deflected, the O.D. and I.D. grow larger until the O.D. contacts the bore. Continued deflection causes the gap ends to move closer together while the O.D. presses against the bore. An Overlap Type Wave Spring permits this type of cycling action in a similar manner. Crest-to-Crest Crest-to-Crest Wave Springs are prestacked in series, decreasing the spring rate proportionally to the number of turns. Uses are typically applications requiring low-medium spring rates and large deflections with low-medium forces. Among major advantages, this design eliminates the need to keep the wave crests aligned. The need to use a key locating device, or to insert a shim between individual springs is not necessary. Because the spring is integrally formed, the wave peaks hold their configuration. As a replacement for helical compression springs, Crest-to-Crest springs can develop similar forces, yet occupy one-half (½) or less the axial space. This allows for strict space constraints. Crest-to-Crest Wave Springs will maintain the same force and load specifications of a conventional round wire spring, but with the advantages of resultant lowered and compacted operating heights, free heights, and solid heights. continued Manufactured in USA Smalley

14 Wave Spring Introduction Wave Spring Types (cont d) Crest-to-Crest with Optional Shim Ends Crest-to-Crest Wave Springs are also available with squared-shim ends. Shim ends provide a 60 contact surface when compared to the wave point contact of plain ends. The shim-ends, under load, more evenly distribute the spring s force upon adjacent components. This feature is similar to the concept of double-disc grinding springs for a flat surface. Shim ends have also been used to affix springs to mating components, as a flat locating surface that may be attached by various methods in the assembly. Nested Nested Wave Springs are pre-stacked in parallel from one continuous filament of flat wire. The need to stack individual springs for higher loads is no longer necessary. Nested springs result in a spring rate that increases proportionally to the number of turns. They can exert tremendous forces, yet maintain the precision of a circular-grain wave spring. In many applications, Nested Wave Springs replace Belleville Springs, particularly in cases where a high but accurate force is needed. WAVO Wavo Springs are produced from round-section wire to provide higher loads while maintaining the accurate loading found in wave springs. As an alternative to Belleville Springs, the Wavo provides similar loads but with an accurate, predictable spring rate. Linear Expanders Linear expanders are a continuous wave formed (marcelled) wire length produce from spring tempered materials. They act as a load bearing device having approximately the same load/deflection characteristics as a wave spring. Forces act axially or radially depending on the installed position. Axial pressure is obtained by laying the expander flat in a straight line. Circular wrapping the expander produces a radial force or outward pressure. Linear expanders are available cut to length or as a continuous coil, for the user to cut as needed. No-Tooling-Charges For Specials

15 Wave Spring Applications B. Face Seal A. Pressure Relief Valve C. Clutch Drive D. Bayonet Connector E. Multi-Tooth Cutter A. Pressure Relief Valve An exact load applied to the top sealing plate was accomplished using a flat wire wave spring. Air pressure entering the top slots forces the plate away from the sealing surface providing the pressure relief mechanism. B. Face Seal Wave Spring applies pressure, to precisely load the carbon face against a mating surface, to properly seal fluids. The spring operates over a fixed working range and provides an exact force, unlike the stamped wavy washer it replaced which could not maintain the necessary spring rate. C. Clutch Drive Pressure on the round belt is produced by compressing the Wavo Spring through the sheave halves. The top threaded cap rotates to adjust the Wavo compression. The Wavo can produce a high force in a tight radial cavity. D. Bayonet Connector Overlap Type Wave Spring installed in an electronic connector assembly. As male and female components are rotated together into final assembly, the wave spring is compressed to its working height. In this position it exerts a constant force that locks both components together. E. Multi-Tooth Cutter A custom designed wave spring with locating tabs is contained in the housing. The spring applies a precise force to the two cutter halves, allowing them to oscillate but not rattle. Manufactured in USA Smalley

16 Wave Spring Applications F. Slip Clutch G. Bearing Pre-Load H. Flow Valve J. Sprinkler Valve I. Low Voltage Connector F. Slip Clutch Clutch drives when the V"- detents are in the V -slots. A Smalley Wave Spring maintains pressure to hold this position. As torque is in creased, the V -detents will ride up and out the V -slots, depressing the wave spring and developing the slip mechanism. When torque is decreased, the wave spring forces the V -detents firmly into the V -slots to drive again. G. Bearing Pre-Load One of the most common wave spring applications world-wide is a bearing preload arrangement as illustrated. Having the proper load will often extend bearing life by lowering operating temperatures, reducing vibration, minimizing wear and providing for quieter and smoother performance. H. Flow Valve As fluid pressure increases the Crest-to-Crest Wave Spring precisely controls the linear displacement of the piston, which positions the orifice for proper fluid flow. Because of the space savings of the Crestto-Crest design, the valve can be made smaller. I. Low Voltage Connector A Bayonet Connector couples as the male end rotates and follows the groove contour in the female end. A -Turn Nested Spirawave Wave Spring provides the pre-load between the two halves. A - Turn Nested Spring was necessary to develop a higher load in very tight radial and axial space. J. Sprinkler Valve With height restrictions accounted for, the Smalley Crest-to-Crest Wave Spring maintains constant pressure on the pop-up head, holding it firmly closed. In operation, water pressure releases the head by overcoming the spring s force. 6 No-Tooling-Charges For Specials

17 Wave Spring Applications K. Oil Valve L. High Speed Pump M. Quick Disconnect N. Vibration Isolator O. Floating Gear K. Oil Valve The force provided by the Crest-to-Crest Wave Spring in this oil valve application precisely regulates the amount of oil that is released. The Crest-to-Crest spring provides accurate resistance in a small space, allowing the overall size of the valve to be greatly reduced. L. High Speed Pump A Smalley Wavo Spring was specified to provide a higher preload (the force needed was greater than offered with a stock Wave Spring) to the tapered roller bearings. Also, the entire bearing/spindle arrangement is held in its housing by a spiral retaining ring. M. Quick Disconnect The sliding member of the disconnect is held in its forward/ locked position against the retaining ring, by the Crestto-Crest Spring. As the user slides the member in the opposite direction compressing the spring, the detent balls align with a groove and release. N. Vibration Isolator Wavo Springs provide high force and a relatively large axial displacement, in limited space. The springs are arranged in series for additional travel. O. Floating Gear Functioning in a contained bracket, a Crest-to-Crest Wave Spring loads a gear with light force allowing axial movement. The gear shown self-aligns with its mating gear during operation.

20 SSR-N Series Narrow Section Wave Springs Smalley narrow section wave springs were originally designed to pre-load packings in telescoping hydraulic cylinders. They have also found other applications where working space is highly limited. This Smalley Wave Spring series is designed to fit into a bore with a light snap to assure perfect concentricity between the wave spring and assembly. When these narrow section wave springs are compressed, radial expansion is taken up by the gap in the spring to eliminate binding. Stock Items in carbon steel and 7-7 PH/C stainless steel.

40 SSRS Series Circular-Grain Shims Smalley Shims are commonly used in conjunction with wave springs where a back-up plate is needed for housings made of softer metals like aluminum or bronze, and for packings made of leather, neoprene or similar materials. Shims can function as spacers to change wave spring operating heights. Adding or subtracting shims is an excellent method of adjusting load on a wave spring. Using a shim spacer can also control tolerance buildups. Stock Items in carbon steel and 7-7 PH/C stainless steel. However, Smalley can make them to order in nearly any size or material.

41 Spring & Fatigue Testers Spring Tester Spring Tester Springs are inspected for load, deflection, free height and spring rate with this compression spring tester, designed and built by Smalley. Main components of the tester are described below. The accuracy in checking spring load/deflection characteristics is dependent on the accuracy and precision of the testing device itself. The concept of accurate compression testing relies greatly on the following tester features:. Upper and lower plates must remain parallel throughout the test. Generally, the distance between upper and lower plates must be within.00 at any point, from zero to full load.. Upper and lower plates must be rigid in that they should not misalign with the spring positioned at any point on the lower plate (note that placing a spring off-center induces a moment, which tends to both tip the plates and cause frictional drag.). The load system must be free of friction, which can cause hysteresis in the load values obtained in the test.. Testing surfaces of both the lower and upper plates must be smooth and free of scratches, cracks or other physical imperfections. Fatigue Tester Fatigue cycling is often a consideration when designing compression springs. Testing provides a more accurate prediction of actual cycle life and is recommended whenever cycle life is critical or when calculations show little margin over the cycle requirement. Ideally, springs should be cycle tested in the actual assembly. Where this is not feasible, Smalley offers testing on high speed cycle machinery. The cycle test machinery can be adjusted to various work heights and stroke lengths to simulate the actual application. Fatigue Tester Manufactured in USA Smalley

42 Ring Introduction Advantages of Spirolox Retaining Rings Spirolox Retaining Rings have No Ears to Interfere in your assembly! Spirolox Rings are manufactured by coiling the ring from flat wire. This unique process produces a retaining ring that has no protruding ears or burrs to interfere with your assembly. Because coiling produces a retaining ring with no scrap, the Spirolox Ring can be economically produced in carbon steel, stainless steel, coppers, and many other alloys. Smalley offers over 6,000 standard parts, which are readily available in both carbon and stainless steel. If you require special designs, take advantage of Smalley's No-Tooling-Cost process; a process perfect for large runs, prototypes and midstream design changes. Whatever your application, Smalley has the cost-effective and innovative design solution. Spirolox Retaining Rings offer many advantages over stamped retaining rings No gap - 60 retaining surface No protruding ears to interfere with mating components (uniform cross-section) Economically produced in stainless steel because the coiling process produces no scrap No-Tooling-Charge on special designs Easy installation and removal No-Tooling-Charges For Specials

43 Ring Introduction Other Ring Types & Special Designs Constant Section Rings Another popular choice of retaining ring configurations is the well known Constant Section Ring. Produced by edgewinding with no special tooling charges, Constant Section Rings have been specified for many years in the automotive and heavy equipment industries as a standard choice of engineers. Smalley has hundreds of standard Constant Section Rings in stock, in carbon steel and stainless steel and in both inch and metric sizes. Special or custom designs can be produced quickly and economically utilizing Smalley s precision No-Tooling-Cost manufacturing process. Constant Section Rings can withstand high forces and impact loads and are easily installed and removed from their internal or external groove for field servicing your product. The WaveRing is a spiral retaining ring with an axial wave form. It acts like a standard retaining ring with the additional feature of compressibility. It compensates for the overall length tolerance of stacked components, while still acting as a retaining ring. Once assembled the WaveRing will reduce looseness and vibration in the assembly. Designed to fit into a groove, the WaveRing applies pressure in two directions: against the groove wall and against the assembly components. Single, double or multiple turns in the WaveRing are possible as well as a choice of materials, including our standard 7-7 ph stainless and carbon steel. Special Rings A major segment of Smalley manufacturing is in special or prototype retaining rings. Common Smalley specials include balanced, multi-turn (,5,6 turns and more) and special ends in diameters from.00 in 0 in (5 mm,000 mm) and larger. Smalley engineers are on hand to help you design a ring specific to your application. Because there are no tooling costs, no job is too big or too little.

47 Ring Applications A. Rubber Boot B. Pneumatic Fitting D. Gear Bracket C. Conduit Connector E. Ratchet Wrench F. Cylinder Housing A. Rubber Boot A -Turn Spirolox Retaining Ring clamps the rubber boot onto the groove making for a nearly perfect seal when the boot is filled with grease. The ring has been deburred so it will not tear into the rubber. B. Pneumatic Fitting An economical (without removal notches or offset) -Turn Spirolox Retaining Ring creates an ID/OD lock, permitting the 60º rotation of the nut. This permanent assembly is commonly used to hold two components together. C. Conduit Connector In this unique application, a Dished Retaining Ring was designed with sharp edges, to bite into the conduit it holds in place. The clamping force of the ring to the conduit (not shown) is achieved by screwing the nut. This decreases the ring s diameter as it advances in a tapered bore. D. Gear Bracket The worm gear shaft is held in place and preloaded using a -Turn Smalley WaveRing. The WaveRing fits an internal groove and the waveform in the ring allows the gear/shaft to float axially as the gear rotates. E. Ratchet Wrench This Single-Turn (it is actually turns) External Retaining Ring retains the internal mechanical components of the ratchet wrench. The additional turn provides that little extra strength needed to prevent the ring from dislodging when the wrench is dropped. F. Cylinder Housing The Hoopster Retaining Ring in this application allows for a shallow groove in the cylinder housing without compromising the ability to have high forces applied to the Hoopster. Because the cylinder is thin, a normal retaining ring groove could not be used. Manufactured in USA Smalley

48 Ring Applications H. Pressure Gauge G. Bike Lock J. Actuator Valve I. Gear Assembly L. Hose Fitting K. Pneumatic Clutch G. Bike Lock Tamper-proof ring holds the lock assembly within its housing. The ring is considered tamper-proof because of reversed removal notches. Also, having a heavy cross-section makes the ring nearly impossible to remove. H. Pressure Gauge A retaining ring designed in a shallow groove exerts very light pressure on the glass lens in this pressure gauge. This single-turn retaining ring design provides the optimum load without breaking the glass. I. Gear Assembly External -Turn retaining ring prevents the pinion shafts from spinning when the gears are rotating. The Spirolox ring snaps securely on the groove and the ring s radial wall is designed to extend radially outward, clearing the four flat pinion shaft pins by.00''. J. Actuator Valve High thrust capacity was needed and a constant section ring was selected to absorb the occasional shock loading of the pistons. K. Pneumatic Clutch The internal components of this clutch are held in the housing using a heavy-duty constant section ring ring. Field servicing was often necessary and the snap ring was the ideal solution to the design requirement. L. Hose Fitting To keep the cap on the fitting, a single-turn retaining ring is located in a shallow internal groove. The wall thickness of the cap is small, so the ring was designed with square corners to operate in a very shallow groove. 8 No-Tooling-Charges For Specials

49 Ring Applications N. Air Vent M. Right Angle Drive O. Pulley P. Belt Pulley Q. ID/OD Lock R. Hip Replacement M. Right Angle Drive Constant section rings secure the bearing assembly by providing removable shoulders in the bore. This simplifies the design of the gear box and replaces costly flanged end plates. N. Air Vent Single-turn, light-duty retaining ring fits tightly in the internal groove of a plastic air vent. Ring ends are dimensioned close together, providing nearly complete 60º ring support. O. Pulley -Turn retaining rings provide 60º side walls as sides of the timing belt pulley. Design eliminates costly pressed-on stamped side walls. For belt replacement one ring can be easily removed. P. Belt Pulley Three hold down screws and a -Turn Spirolox Ring form a bi- directional shoulder. The shaft is inserted through the pulley and the retaining ring rests on the pulley face securing the shaft in one direction. Movement is prevented in the other direction with the three screws clamping down on the ring. Q. ID/OD Lock Single-turn retaining ring operates in an internal and external groove at the same time, commonly referred to as an ID/OD Lock. In this application, the ring fits tight on the body (shaft) groove and extends radially into the nut (housing). This allows the nut to spin freely but not come off the body. R. Hip Replacement A titanium Spirolox Retaining Ring is used in this hip replacement application to secure the shell and the liner together to form the socket of the new hip. Smalley s manufacturing process allows for the economical production of special alloy products. Manufactured in USA Smalley

50 Assembly Methods Manual Installation Manual installation on an individual or low production basis is accomplished as follows: Separate the ring coils and insert one end of the ring into the groove. Wind the ring by pressing down around the circumference until the entire ring is inserted into the groove. Housing: Shaft: Semi Automated and Automated Installation For higher speed and automated assembly operations, simple tooling or assembly fixtures can be designed. External installation on a shaft can be accomplished with a plunger and tapered plug. The plug, angled at approximately 6 degrees, is centered over the shaft end. A loose fitting plunger pushes the ring into position over the tapered plug. An arbor press or air cylinder is commonly used to automate this assembly operation. Plunger Ring Plug Shaft 50 No-Tooling-Charges For Specials

51 Assembly Methods Internal retaining ring installation is accomplished in a similar manner. A tapered bore, which acts as a ring contracting guide, and a plunger pushes the retaining ring into position. Tooling for ring installation should have hardened working surfaces to minimize wear. Plunger Ring Sleeve Housing Using Screwdriver Removal Smalley Retaining Rings are supplied standard with removal notches to enable easy extraction from a groove. The notch is provided to form a small gap between the ring end and the shaft or housing, permitting a blunt object to be inserted at the end of the ring to pry the free end out radially and up. Insert a screwdriver or dental pick behind the removal notch. Use the tool to pry out the first end of the ring. Manually spiral the ring around until it is free from the groove. Using Dental Pick Smalley Tooling Smalley s Spirolox Retaining Ring Removal Tool, part number RT-07, fits between the layers of a multiple turn retaining ring in order to access the removal notch. The end of the tool bit is slotted for the tip of the notch end to pass through. Once inserted, the ring end may be pulled out radially and up.

100 Laminar Seal Rings A Smalley Laminar Seal Ring is a metallic labyrinth seal consisting of multiple rings in a groove. This arrangement of the rings and the specific orientation of the rings are dictated by the application and the severity of the environment. Applications: High Temperatures Heavy Splash Water Protects Against Grit/Dirt Protects Rubber Seals Standard Sizes: 5 8'' to 50'' 5 mm to,00 mm Laminar Seal Rings Available From Stock Standard parts from 5 8'' to 50'' and 5 mm to,00 mm. Special seals manufactured with No-Tooling-Charges. Smalley s Laminar Seal Rings are interchangeable with FEY Rings.

101 Laminar Seal Rings There are 6 series of STANDARD English & Metric Laminar Seal Ring configurations from which to select. Eight of these series are sets consisting of single-turn rings. The other 8 series are sets consisting of double-turn rings. Within each series are operational ring-set configurations in both English & Metric sizes. The selection of the appropriate set should be determined by the application. For some applications a complete labyrinth configuration (i.e.; a complete labyrinth configuration is one which has rings staggered within the set) is necessary due to a severe environment where contamination is highly probable. In other applications design engineers can keep the groove dimensions minimal by specifying laminar sets with rings clinging either to the bore or to the shaft. Selection Guide Standard Laminar Ring Sets Available Single-Turn Laminar Seal Rings Used in a variety of applications, this series of Seal Rings should be utilized for light to medium duty applications, dependent on the ring configuration specified. The sets are compromised of single-turn rings in either rings per set or 5 rings per set. APPLICATIONS: Three ring sets protect components from low dirt and low splash water contamination. Five ring sets provide a better labyrinth seal to protect components from medium dirt and medium splash water contamination. YH Series QH Series Internal - Light Duty set = individual rings (rings rotate with bore only) YS Series QS Series External - Light Duty set = individual rings (rings rotate with shaft only) YHK Series QHK Series Internal - Medium Duty set = 5 individual rings ( rings rotate with bore & rings rotate with shaft) YHK Series QHK Series External - Medium Duty set = 5 individual rings ( rings rotate with shaft & rings rotate with bore) Double-Turn Laminar Seal Rings The sets are compromised of double-turn rings in either rings per set or rings per set. The double-turn rings fit tighter in the bore or on the shaft, provide complete 60 surface contact and resist higher axial/radial forces than single-turn ring sets, for medium to heavy duty applications. YHD Series QHD Series Internal - Medium/Heavy Duty set = individual rings (rings rotate with bore only) YHKD Series QHKD Series Internal - Heavy Duty set = individual rings ( rings rotate with bore & rings rotate with shaft) APPLICATIONS: Two ring sets protect components from medium dirt and medium splash water contamination. Three ring sets provide a better labyrinth seal to protect components from heavy dirt and heavy splash water contamination.

102 Custom-Made Rings & Springs Custom For your Application While Smalley has a large selection of stock retaining rings and wave springs to choose from, the uniqueness of applications often demands a ring or spring to conform to application-specific requirements. Our No-Tooling-Cost process provides an economical alternative, to produce a custom ring or spring to meet your exact specifications. Think of it as modifying a standard; change the diameter, material size, alloy or nearly any product characteristic to fit within your assembly. It s really a simple solution to get exactly what works best. At Smalley, specials are standard, as many of our accounts take advantage of getting exactly what works best. Retaining rings and wave springs are often the last design consideration in an assembly and commonly have to fit in restrictive spaces and need to provide critical operating characteristics. Having the ability to easily specify non-standard sizes, offers a preferred option designers will often follow. Economical A common misconception of special designs is the cost. Because of Smalley s unique manufacturing process, application-specific retaining rings or wave springs can be an economical solution for your unique needs. With Smalley s No-Tooling-Cost process we have the flexibility to quickly manufacture products of different diameter, thickness, material and finish at a minimal cost. This means that during the prototype stage we can produce alternative designs with no tooling modifications. It s not uncommon to produce one prototype for evaluation and subsequently make dimensional adjustments for a second single prototype. That s two setups, NO-TOOLING-CHARGES and a final product produced fast and economically. Availability Smalley is vertically integrated with onsite material manufacturing and a large warehouse. We are able to produce custom rings or springs using a wide variety of readily available materials, or can produce custom raw material sizes to meet delivery requirements. For customers who use just-in-time inventory control, Smalley will offer to stock parts for immediate shipment, ready for the next purchase order or blanket order release. Lead Time Whether you are looking for prototypes, short-runs or high volumes, Smalley s unique No-Tooling-Cost manufacturing process allows for special designs to be manufactured in a timely fashion. Since no special dies or forming tools are necessary for custom rings or springs, prototypes can be designed and produced in days, not weeks. 0 No-Tooling-Charges For Specials

Our capabilities extend well beyond the ordinary manufacturer as we not only design the rings and springs, we design the machinery they run on. We have in-depth knowledge of mechanical assemblies, machining operations, fitting components, dynamics and a host of other elements in the diverse universe of mechanical components. Product Application Engineers have designed and solved thousands of tough applications for OEMs in nearly every industry. Whether it s exposure to high temperature or a cryogenic environment, a dynamic / fatigue problem or simply a static load, we ve been involved and resolved complex design issues. Smalley engineers establish the manufacturing processes needed. This includes primary coiling operations, secondary operations for special product features such as slots, tabs, holes, bends, hooks, joints, etc., plating and finishing, marking and other characteristics for most any feature required. To develop a packaging solution, Smalley engineering has created standards with which solutions are offered for consideration. Whether the part is coinwrapped, bulk packaged, wire tied, on a tube or individually bagged a Smalley engineer is involved with all aspects of handling and shipment. Optimized Design Smalley has developed sophisticated software that optimizes the variables in a given design. It considers both the dimensions of the product and the cost to produce the ring or spring. The typical analysis provides a product that performs to specification but does not over-design dimensions and/or materials that can raise costs. Because our No-Tooling-Cost process enables an almost infinite selection of dimensions, the software considers the relationships between maximum stress levels, product configurations and dimensions, and pushes the limits in the choices available for the best design. Based upon the criteria selected, Smalley engineers work with you to best determine what design alternatives will work best for a particular application. By making simple design changes; such as material thickness, radial wall, number of waves or selecting a different alloy, we can quickly determine the design impact. This time saving technology allows for correct parts to be manufactured and ready to test. Testing In-house testing is performed on our products to ensure that they satisfy our stringent quality standards prior to shipment. Statistical Process Control, SPC, is performed on a sampling of parts to verify that critical dimensions are in control. Smalley has the ability to test various application-specific performance characteristics. An example would be cycle life. Cross-Functional Teams Housing both the manufacturing and office activities under one roof allows Smalley engineers to be involved in all aspects of support in the manufacturing process. From concept to production our engineers work with quality control, manufacturing, shipping and purchasing to ensure that the design and production process move efficiently and effectively. Re-Engineering If you are currently considering using Spirolox Retaining Rings or Smalley Wave Springs to replace an existing product, our engineering department will work with you to choose the best new design for your application. Send Smalley a sample of an existing ring or spring, drawings of the assembly or your design requirements and we will engineer and provide new solutions for your consideration. Once an alternative design is presented, engineering will work with you to obtain exact prototypes or samples of similar products for evaluation and testing. Mid-Stream design changes can also be accomplished with relative ease. It is not uncommon that dimensions need modification right in the middle of production. Once again, Smalley products can usually be changed at any point in the process by making a machine adjustment, without any tooling changes. You can count on the flexibility Smalley products offer for all your applications. Manufactured in USA Smalley

105 Material Types Material Types Selecting the proper material for an application requires a general knowledge of what is commonly available for use in Smalley flat wire products. Specifying the correct material can prevent additional cost and failure in operation. Carbon steel is the most commonly specified material. Stainless steels, although more costly than carbon steel, provide far superior corrosion resistance and have higher temperature operating limits. Carbon Steel Oil Tempered SAE high carbon tempered spring steel is a standard material for spiral retaining rings and wave springs. Tensile strength and yield strength are maximized as a result of the oil tempered martensitic structure. Hard Drawn SAE high carbon cold drawn spring steel is a standard material for snap rings. Hard drawn carbon steel has no scale as it receives its strength from the drawing process. In either temper, carbon steel is best suited in applications having a protected environment as it corrodes if not lubricated or atmospherically sealed. Additional corrosion protection can be added with special finishes. Rings and springs are normally supplied with an oil dip finish providing protection during shipment and for shelf storage. Carbon steel is highly magnetic and can be a variety of different colors including blue, black and gray. Stainless Steel 0 Stainless Steel 0 is the standard stainless steel for spiral retaining rings. This widely used material is specified because of its combination of corrosion resistance and physical properties. 0 obtains its spring temper condition by cold working. Though it is categorized as being a nonmagnetic stainless, 0 becomes slightly magnetic as a result of cold working. It is not hardenable by heat treatment. 0 has a silver-gray color. 6 Stainless Steel Nearly identical in physical properties and heat resistance to 0, 6 provides additional corrosion resistance, particularly against pitting, due to its molybdenum chemical content. 6 is generally used in food, chemical and sea water applications. 6 shows less magnetism than 0. However, as with 0, magnetism increases as the wire is cold reduced. This stainless grade is also not hardenable by heat treatment. 6 has a silver-gray color. 7-7 PH/C Stainless Steel Similar in corrosion resistance to type 0, this alloy is used almost exclusively for wave springs, yet offers both high tensile and yield strengths for special ring applications. In fatigue and high stress applications, 7-7 out performs even the finest grade of carbon steel. Spring properties are achieved by precipitation hardening Condition C to Condition CH-900. As a result, the material may be subjected to a temperature of C without a loss of spring properties. 7-7 PH C/CH-900 exhibits magnetism similar to high carbon steel. After precipitation hardening, 7-7 has a blue, brown or silver color as a result of open-air heat treatment, although atmosphere controlled heat treatment provides a bright color.

106 Material Types Super Alloys Inconel X-750* This nickel-chromium alloy is used most commonly in high temperature and corrosive environments. Two commonly specified tempers of Inconel are described below. Most commonly, Inconel X-750 is precipitation heat treated to a spring temper condition. In this state, it has temperature resistance to 700 F. The National Association of Corrosion Engineers (NACE) approves this hard temper to specification MR-0-75 (Rc50 maximum) for spiral retaining rings and wave/compression springs. # temper, which requires a longer heat treatment than spring temper, has a lower tensile strength but provides temperature protection to 000 F. Both spring temper and # temper may be heat treated in either an open air or atmosphere controlled furnace. Open air heat treatment may produce oxidation, which often results in a slight black residue. An atmosphere controlled environment eliminates oxidation and produces a component with no residue. n Rings and springs manufactured from this grade of Inconel have a blue/silver-gray color and exhibit no magnetism. A86 Alloy In applications up to 000 F, this alloy exhibits similar properties to Inconel X-750. Its spring temper condition is obtained by precipitation hardening. A86 may be heat treated similar to spring temper and # temper Inconel. n This material exhibits no magnetism and has a blue/silver-gray color. Elgiloy* Known for its excellent resistance to corrosive environments and use at elevated temperatures, this relatively new spring material is now readily available from Smalley. Commonly used in oil industry applications, Elgiloy shows improved reliability over other NACE approved materials by resisting sulfide stress cracking. Additionally, Elgiloy is said to out perform over 600% better than 7-7 PH in load retention at 650 F and provide over 00% more cycles (in fatigue resistance) than carbon steel, without breakage. n Elgiloy exhibits no magnetism and is blue-brown in color as a result of heat treatment. Coppers Beryllium Copper Alloy #5 Normally specified in a hard temper, this alloy produces excellent spring properties due to a combination of low modulus of elasticity and high ultimate tensile strength. The alloy gains its physical properties by precipitation hardening. In contrast to other copper alloys, beryllium copper has the highest strength and offers remarkable resistance to loss of physical properties at elevated temperatures. n Beryllium copper is nonmagnetic. Its electrical conductivity is about - times as great as phosphor bronze Phosphor Bronze, Grade A Phosphor bronze offers fair spring properties, fair electrical conductivity and is rated a step below beryllium copper in performance. It is purchased in a spring temper condition to maximize spring characteristics. n Phosphor bronze is hardenable only by cold working. This material is also nonmagnetic. *INCONEL X-750 is a registered trademark of Special Metals Corporation.

107 Material Finishes Material Finishes Black Oxide MIL-DTL-9, Class This finish provides a flat black finish. Black oxide is intended more for cosmetic appearance than for corrosion resistance. Cadmium Plating Cadmium Plate, AMS-QQ-P-6, Type I, Class, Cadmium Plate w/chromate Dip, AMS-QQ-P-6, Type II, Class Cadmium plating is used on carbon steel to increase the corrosion resistance of the product. The process of cadmium plating spiral retaining rings is costly and subjects the ring to the possibility of hydrogen embrittlement. Smalley offers stainless steel as the preferable option to cadmium. Oil Dip This is the standard finish for all Smalley products produced from carbon steel. The oil provides resistance to corrosion in transport and normal storage. The oil dip finish should not be considered a permanent finish. Passivation AMS 700, Method, Type, Class Passivation is an optional cleaning operation for stainless steel. It provides a bright finish and increased corrosion resistance. Passivation dissolves iron particles and other substances, which have become imbedded in the surface of stainless steel during production. If not dissolved, these foreign particles could promote rusting, discoloration or even pitting. In theory, the corrosion resistance of stainless steel is due to the thin, invisible oxide film that completely covers the surface of the ring and prevents further oxidation. Removing the contaminates prevents breaks in the oxide film for optimum corrosion resistance. Zinc Phosphate MIL-DTL-6, Type Z, Class This finish is sometimes referred to as Parkerizing and appears gray-black in color. The corrosion resistance of phosphate is superior to black oxide but inferior to cadmium plating or stainless steel. Phosphate can not be applied to stainless steel. Vapor Degrease/Ultrasonic Clean This is the standard cleaning and finish for all stainless steels. The process removes oil and other organic compounds from the material surface by use of a chlorinated solvent. The solvent effectively removes oil and grease from the exposed surfaces of the ring or spring. Ultrasonics are used in forcing the solvent to act between the turns of the ring. Vibratory Deburr/Hand Deburr Though all circumferential surfaces and edges of Spirolox Rings are smooth, sharp corners are always present on the gap ends due to the cut-off operation. To break the sharp corners, achieving a blended/smooth surface finish, rings may either be vibratory or hand deburred to meet your specifications. Manufactured in USA Smalley

108 Materials Specifications Federal, aerospace and other regulating agencies have prepared several specifications for sheet and strip materials, but few have been published for flat wire. Smalley procures its material to internally generated specifications. In addition to controlling tensile strength, rigid inspection procedures have been established to check for edge contour, physical imperfections, camber, cross-section and chemical composition. A B B A Ultimate Tensile Strength To check the spring properties of wire, Ultimate Tensile Strength is the preferred test method over hardness because spring temper flat wire develops different hardnesses at various indentation points. As a result of cold rolling, the top and bottom surfaces ( A ) become harder as they are more severely worked than the round edge areas ( B ). Tensile tests are more consistent as they evaluate the entire crosssection, not a single point as in a hardness test No-Tooling-Charges For Specials

109 Spring Design LOAD (P) WORK HEIGHT Spring Design Defining the Spring Requirements Although wave spring applications are extremely diverse, there is a consistently basic set of rules for defining spring requirements. Those requirements are used to select a stock/standard spring or design a special spring to meet the specifications. Working Cavity The working cavity usually consists of a bore the spring operates in and/or a shaft the spring clears. The spring stays positioned by piloting in the bore or on the shaft. The distance between the loading surfaces defines the axial working cavity or work height of the spring. Load Requirement The load requirement is defined by the amount of axial force the spring must produce when installed at its work height. Some applications require multiple working heights, where loads at or more operating heights are critical and must be considered in the design. Often minimum and/or maximum loads are satisfactory solutions, particularly where tolerance stack-ups are inherent in the application. Operating Environment High temperature, dynamic loading (fatigue), a corrosive media or other unusual operating conditions must be considered in spring applications. Solutions to various environmental conditions typically require selection of the optimal raw material and operating stress. Standard Springs vs. Special Springs Finding the right spring can be as easy as selecting a standard catalog item.

112 Spring Design Stress Operating Stress Compressing a wave spring creates bending stresses similar to a simple beam in bending. These compressive and tensile stresses limit the amount a spring can be compressed before it yields or takes a set. Although spring set is sometimes not acceptable, load and deflection requirements will often drive the design to accept some set or relaxation over time. Maximum Design Stress Static Applications Smalley utilizes the Minimum Tensile Strength found in this catalog s Materials section to approximate yield strength due to the minimal elongation of the hardened flat wire used in Smalley products. When designing springs for static applications we recommend the calculated operating stress be no greater than 00% of the minimum tensile strength. However, depending on certain applications, operating stress can exceed the minimum tensile strength with allowances for yield strength. Typical factors to consider are permanent set, relaxation, loss of load and/or loss of free height. Dynamic Applications When designing wave springs for dynamic applications, Smalley recommends that the calculation of operating stress not exceed 80% of the minimum tensile strength. Refer to the Fatigue Stress Ratio and Table for further fatigue guidelines. Residual Stress/Pre-Setting Increasing the load capacity and/or fatigue life can be achieved by compressing a spring beyond its yield point or presetting. Preset springs are manufactured to a higher than needed free height and load and then compressed solid. Both the free height and load are reduced and the material surfaces now exhibit residual stresses, which enhance spring performance. Fatigue Fatigue cycling is an important consideration in wave spring design and determining precisely how much the spring will deflect can greatly impact the price of the spring. An analysis should include whether the spring deflects full stroke or only a few thousandths each cycle or possibly a combination of both as parts wear or temperature changes. The fatigue guidelines in Table provide a conservative approach and allow for calculation of cycle life between work heights. Although these methods of fatigue analysis have proven to be a good approximation, testing is recommended whenever cycle life is critical. Formula: Fatigue Stress Ratio = X = (σ S ) (σ S (refer to Table ) ) Where: σ = Material tensile strength S = Calculated operating stress at lower work height (must be less than σ) S = Calculated operating stress at upper work height Fatigue Guidelines X Estimated Cycle Life <.0 Under 0, ,000 50, ,000 75, ,000 00, ,000 00, ,000,000,000 >.70 Over,000,000 Table Load/Deflection A comparison of the actual spring rate to the theoretical (calculated) spring rate provides practical limits for the working range of the spring. Spring rate (P/f) can be calculated by manipulating the deflection equations. See formulas in the Spring Design section. Figure shows a graph of theoretical and tested spring rate. Typically, theoretical rate is accurate until the spring starts to bottom out or reach its solid height. As a general rule, the calculated spring rate is linear through the first 80% of available deflection and for work heights down to times the solid height. Although the spring can operate beyond this linear range, measured loads will be much higher than calculated. Figure No-Tooling-Charges For Specials

113 Spring Design Hysteresis Wave springs exert a greater force upon loading and lower force upon unloading. This effect is known as hysteresis. The shaded area shows a graphic representation between the curves in Figure. In a single turn spring, friction due to circumferential and radial movements are the prime causes. Crest-to-Crest and Nested Springs also contribute to the frictional loss as adjacent layers rub against each other. Sufficient lubrication will minimize this effect. Figure Design Guidelines Material Cross-Section Material cross-section plays an important role in wave spring design. The most economical materials are those used in manufacturing Smalley standard springs and retaining rings. In addition, many other material cross sections are commonly used in special spring manufacture designs. Smalley engineering can provide assistance in selecting an economical alloy and cross section. As a basic guideline, use our standard SSR -Wave Spring series for cross-section/diameter relationships. Lighter material sections are usually acceptable. Heavier sections for a given diameter may be incorporated using the following information: Special wave spring design criteria for selecting material cross-sections: Maximum material thickness = standard ( SSR- ) thickness * Maximum radial wall = material thickness (any value) * 0 Minimum radial wall = material thickness (any value) * Solutions to this problem include dimensioning the spring to pilot closely on the I.D. and/or O.D. or designing the spring as a single turn Gap Type. Diameters Figure illustrates two methods of specifying diameters. In either case, the spring diameter is developed to provide proper operation between the bore and the shaft. Note: Smalley s manufacturing process of edgewinding controls either the O.D. or the I.D. The material radial wall is also tightly controlled. Therefore whenever possible, tolerance only one diameter and the radial wall instead of tolerancing both the O.D. and I.D. Bore Pilot For springs that pilot in the bore as shown in figure a, the bore and shaft diameters should be included in the spring specifications. Commonly used requirements would read: Spring must pilot and operate in a (minimum bore) bore diameter. Spring must clear a (maximum shaft) shaft diameter. The actual spring diameter is then developed at time of manufacture to provide the best fit and prevent binding due to expansion. For Gap Type and Overlap Type Springs, the outside diameter can be specified because binding is not a concern. The outside diameter can be toleranced to provide a minimum clearance in the bore or provide cling in the bore, as do the Smalley Bearing Preload Springs. Shaft Pilot For springs that pilot on a shaft as shown in Figure b, the inside diameter can be toleranced to provide a minimum clearance from the shaft. Since wave springs expand during compression, interference with the shaft is generally not a concern. To insure proper operation, include shaft and bore diameters in the spring specifications. Commonly used requirements would read: Spring pilots over and clears a (maximum shaft) shaft diameter. Spring operates in a (minimum bore) bore diameter. For Overlap Type Wave Springs and multiple turn Spirawaves, the radial wall must be sufficient to prevent misalignment between adjacent layers. For springs with a narrow radial wall, radial misalignment can occur during handling or during operation if the spring is not contained or closely piloted.

114 Engineering Support Engineering Design Spirolox Retaining Ring and Constant Section Ring applications, although diverse, can be analyzed with a straight forward set of design calculations. There are four main areas that should be considered in most applications.. Material Selection. Load Capacity. Rotational Capacity. Installation Stress Smalley Application Engineers are available to provide immediate technical assistance. The following pages of Spirolox Retaining Ring and Constant Section Ring engineering design have been developed from over 5 years of extensive testing and research into the various applications of retaining rings. The formulas are provided for the preliminary analysis of a ring application and the design of a Spirolox Retaining Ring. Design engineers commonly associate the word retaining ring to a basic style or type of retaining device. In reality, retaining rings are nearly as diverse as their applications. Spirolox Retaining Rings offer a distinct alternative, and in many instances an advantage, over the more common retaining rings available on the market today. Some of the major distinctions are: Spiral Wound in Multiple Turns Increases load capacity yet allows easy assembly by hand or as an automated process. 60 Retaining Surface No gap no protruding ears. Diameters from.00" to 0" Uniform Radial Section Provides a pleasant appearance on the assembled product. Beneficial when radial clearance is limited. Simplified Assembly Wind into groove. No special pliers/tools needed to install or remove. Removal notch provided for easy removal using a screwdriver. Design Flexibility Ring thickness can be changed to accommodate most any application by either varying material thickness and/or number of turns. Standard rings meet military and aerospace specifications. Special designs are produced quickly and economically in many alloys. No-Tooling-Charges For Specials

115 Ring Design Load Capacity Understanding the load capacity of a Spirolox Retaining Ring assembly requires calculations for both ring shear and groove deformation, with the design limitation being the lesser of the two. The load capacity formulas do not take into account any dynamic or eccentric loading. If this type of loading exists, the proper safety factor should be applied and product testing conducted. In addition, the groove geometry and edge margin (i.e., the distance of the groove from the end of the shaft or housing) should be considered. When abusive operating conditions exist, true ring performance is best determined thorough actual testing. Ring Shear Although not commonly associated as a typical failure of Spirolox Retaining Rings, ring shear can be a design limitation when hardened steel is used as a groove material. Ring thrust load capacities based on ring shear are provided within this catalog s tables of standard rings. These values are based on a shear strength of carbon steel with the recommended safety factor of. Formula: P R = D T S S π K Where: P R = Allowable thrust load based on ring shear (lb) D = Shaft or housing diameter (in) T = Ring thickness (in) S S = Shear strength of ring material (psi) K = Safety factor ( recommended) Example:. WH-550-S6. Safety factor = (.07) 08,000 (π) P R = P R =,787 lb RING SHEAR Groove Deformation (Yield) Groove deformation is by far the most common design limitation of retaining rings. As permanent groove deformation occurs, the ring begins to twist. As the angle of twist increases, the ring begins to enlarge in diameter. Ultimately, the ring becomes dished and extrudes (rolls) out of the groove. As a conservative interpretation, the following equation calculates the point of initial groove deformation. This does not constitute failure which occurs at a much higher value. A safety factor of is suggested. Ring thrust load capabilities based on groove deformation are provided within this catalog s tables of standard rings. Formula: P G = D d S y π K Where: P G = Allowable thrust load based on groove deformation (lb) D = Shaft or housing diameter (in) d = Groove depth (in) S y = Yield strength of groove material (psi), see Table K = Safety factor ( recommended) Example:. WH-550-S6. Groove material yield strength = 5,000 psi. Safety factor = PERMANENT MATERIAL DEFORMATION (.07) 5,000 (π) P G = P G = 8,769 lb The thrust load based on ring shear above, must be compared to the thrust load based on groove deformation to determine which is the limiting factor in the design. Typical Groove material yield strengths Hardened Steel 860 0,000 psi Cold Drawn Steel 08 70,000 psi Hot Rolled Steel 08 5,000 psi Aluminum 07 0,000 psi Cast Iron 0-0,000 psi Table Since ring shear was calculated at,787 lb, the groove yields before the ring shears. Therefore 8,769 lb is the load capacity of the retaining ring. Manufactured in USA Smalley

116 Ring Design Groove Geometry Groove Radius To assure maximum load capacity it is essential to have square corners on the groove and retained components. Additionally, retained components must always be square to the ring groove in order to maintain a uniform concentric load against the retained part. The radius at the bottom of the groove should be no larger than Table states. Shaft or Housing Maximum Radius Diameter on Groove Bottom inch and under.005 Max. Over inch.00 Max. Table SHARP CORNER MAXIMUM RADIUS ON BOTTOM Retained Component The retained part ideally has a square corner and contacts the ring as close as possible to the housing or shaft. The maximum recommended radius or chamfer allowable on the retained part can be calculated with the following formulas. Formula: Maximum Chamfer =.75(b - d) (on retained component) MINIMIZE DISTANCE MAXIMUM CHAMFER b Where: b = Radial wall (in) d = Groove depth (in) Example:. WH-00 Maximum Chamfer =.75( ) =.00 in Maximum Radius =.5( ) =.07 in Formula: Maximum Radius =.5(b - d) (on retained component) MINIMIZE DISTANCE MAXIMUM RADIUS d b d Edge Margin Ring grooves which are located near the end of a shaft or housing should have an adequate edge margin to maximize strength. Both shear and bending should be checked and the larger value selected for the edge margin. As a general rule, the minimum edge margin may be approximated by a value of times the groove depth. Z Formula: Shear K P z = S Y D G π Bending K 6 d P z = S Y D G π Example:. VS-5. Groove material yield strength = 0,000 psi. Safety factor =.

117 Ring Design Rotational Capacity The maximum recommended RPM for all standard external Spirolox Retaining Rings are listed in the ring tables of this manual. A Spirolox Retaining Ring, operating on a rotating shaft, can be limited by centrifugal forces. Failure may occur when these centrifugal forces are great enough to lift the ring from the groove. The formula below calculates the RPM at which the force holding the ring tight on the groove (cling) becomes zero. Rapid acceleration of the assembly may cause failure of the retaining ring. If this is a potential problem, contact Smalley engineering for design assistance. Maximum RPM Formula: N = 600 V E I g (π 5 ) Y γ A R M ½ Where: N = Maximum allowable rpm (rpm) E = Modulus of elasticity (psi) I = Moment of inertia = (t x b ) (in ) g = Gravitational acceleration (in/sec ), 86. in/sec V = Cling = (D G - D I ) (in) D G = Groove diameter (in) D I = Free inside diameter (in) Y = Multiple turn factor, Table n = Number of turns γ = Material density (lb/in ), (assume.8 lb/in ) A = Cross sectional area = (t x b) - (.)t (in ) t = Material thickness (in) b = Radial wall (in) R M = Mean free radius = (D I + b) (in) n Y Table Example:.

(π ).07 (.8).0076 (.75) 5 N = 6,59 rpm ½ Self-Locking This feature allows the ring to function properly at speeds that exceed the recommended rotational capacity. The self-locking option can be incorporated for both external and internal rings. The self-locking feature utilizes a small tab on the inside turn locking into a slot on the outside turn. Self-locking allows the ring to operate at high speeds, withstand vibration, function under rapid acceleration and absorb a degree of impact loading. Balanced Smalley s balanced feature statically balances the retaining ring. A series of slots, opposite the gap end, account for the missing material in the gap. This characteristic is very useful when the balance of the assembly is critical and it is necessary to reduce eccentric loading. Left Hand Wound Smalley retaining rings are wound standard in a clockwise direction. In special applications it is sometimes favorable to have the retaining ring reverse, left hand wound.

119 Ring Design Installation Stress Analysis The equations provided are used to check that the elastic stress limit of the ring material is not exceeded by stress due to installation. Standard parts that are assembled manually in the recommended shaft/bore and groove diameters do not require stress analysis. Special rings, or rings being assembled with special tooling, require stress analysis. To select a safe stress value, it is necessary to estimate the elastic limit of the raw material. The minimum tensile strength, as shown in the materials table of the catalog, can be used as a suitable estimate. As with any theoretical calculation, a closer analysis of the actual application may reveal that these stress values can be exceeded. However, particular consideration must be made to functional characteristics such as installation method, the number of times the ring will be installed and removed, thrust load and/or centrifugal capacity. After forming, the ring s natural tendency is to return to its original state. This places the inner edge of the radial wall in residual tension and the outer edge in residual compression. To account for the residual stress in the ring when expansion is taking place, only 80% of the minimum tensile strength should be used to compare to the installation stress; see Table. In special designs, where the installation stress exceeds the material s elastic limit, rings can be produced to diameters which will yield a predetermined amount during assembly. Once installed, the ring will have the proper cling (grip) on the groove. Installation Stress Formula: For external rings For internal rings E b (D S E = S - D I ) (D I + b)(d S + b) S C = E b (D O - D H ) (D O - b)(d H - b) Where: S E = Stress due to expansion (psi) S C = Stress due to compression (psi) E = Modulus of elasticity (psi) b = Radial wall (in) D S = Shaft diameter (in) D H = Housing diameter (in) D I = Free inside diameter, minimum (in) D O = Free outside diameter, maximum (in) Percent of Minimum Application Tensile Strength Shaft 80% Housing 00% Table Example: Compare theoretical installation stress to percent of minimum tensile strength.. WS-00-S0 8,000,000 (.075) ( ) S E = ( )( ) S E = 9,85 psi Minimum tensile strength of the ring material: 0,000 psi. Using 80%, (Table ), of 0,000 psi = 68,000 psi. 9,85 psi < 68,000 psi Since the installation stress is less than 80% of the minimum tensile strength, permanent set is not expected.

121 Hoopster Design Ring Abutment Unlike a conventional Spiral Retaining Ring or Snap Ring, the retained component in a Hoopster Retaining Ring* assembly may have a corner break. Thrust load is not sacrificed when the retained component has a broken corner because the moment arm is negligible in a Hoopster design. The sketches above illustrate acceptable abutment practice. Groove Design and Geometry Groove deformation is by far the most common design limitation of most retaining rings. Unlike a conventional retaining ring or snap ring that fails by deforming and twisting, the Hoopster Retaining Ring shows superior strength from its low profile and mechanical advantage over traditional retaining rings under load. With a Hoopster, there is no moment arm that twists the ring causing premature failure as with a conventional retaining ring. The shallow groove specification of a Hoopster makes the groove wall a critical specification, to ensure the function of the ring. To obtain maximum load capacity from a Hoopster Retaining Ring, it is essential to have sharp corners on the groove. The maximum radius on the groove bottom should be no greater than 0% of the ring s radial wall. Maintaining a sharp corner on the top of the groove is just as critical. Formula: Maximum Radius on Groove Bottom =.0b Where: b = Ring radial wall Thrust Capacity The shallow groove depth associated with a Hoopster, in combination with the groove material, are the controlling factors in determining thrust capacity. The Hoopster does not twist when loaded so pure thrust load based on the yield strength of the groove material maximizes the Hoopster s load carrying capacity. Formula: P G = D d S y π K Where: P = Allowable thrust load based on groove deformation (lb) D = Shaft or housing diameter (in) d = Groove depth (in) S y = Yield strength of groove material (psi) K = Safety factor ( recommended) Typical Groove Material Yield Strengths Hardened Steel 860 0,00 psi Cold Drawn Steel 08 70,000 psi Hot Rolled Steel 08 5,000 psi Aluminum 07 0,000 psi Cast Iron 0-0,000 psi Table 5 *PATENT PENDING Manufactured in USA Smalley

Particularly accurate for spring steels, as there is only a small difference between ultimate tensile strength and yield strength. Thrust Load Capacity (P G ) or (P R ): Overall capacity of an assembly to withstand a given value of thrust load in pounds. The limitation being the lesser of two mathematical calculations: ring thrust load capacity (P R ) or groove thrust load capacity (P G ). Yield Strength (S y ): The stress at which a material exhibits initial plastic deformation. WAVO: Single turn round wire wave spring. Manufactured in USA Smalley
