5 PRECISION PRODUCTS FOR CRITICAL APPLICATIONS All Smalley retaining rings, wave springs and constant section rings are manufactured with our unique edgewinding 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 are coiled 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 where space is at a premium. 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 the spring cavity by as much as 50%. Of course, this will also reduce the weight and raw material cost of the assembly. Constant Section Rings Constant section rings, or snap rings, are often specified for heavy duty or impact-loading applications. Produced by edgewinding, they are fixtures in the automotive and heavy equipment industries as their larger cross section produces strength and durability. In addition, a variety of Smalley end types are available for easy application in a wide range of applications.

10 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.

11 Wave Spring Introduction Wave Spring Types 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. Gap Type Wave Spring Overlap Type Wave Spring 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 ( ) 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 (87)

12 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 Springs Linear springs 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 linearly or radially depending on the installed position. Axial pressure is obtained by laying the spring flat in a straight line. Circular wrapping the spring produces a radial force or outward pressure. Linear springs are available cut to length or as a continuous coil, for the user to cut as needed.

13 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 (87)

14 Wave Spring Applications F. Slip Clutch G. Bearing Pre-Load H. Flow Valve I. Low Voltage Connector J. Sprinkler Valve 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 Crest-to-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. smalley.com No-Tooling-Charges For Customs

15 Wave Spring Applications K. Oil Valve L. Ball Valve 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. Ball Valve A Smalley Crest-to-Crest Wave Spring is used to reduce the overall spring height in this application. The wave spring allows the seat to oscillate on the ball, keeping a tight seal in the operating position. The reduction in spring height and resulting smaller spring cavity also reduce the weight of the valve. M. Quick Disconnect The sliding member of the disconnect is held in its forward/locked position against the retaining ring, by the Crest-to-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.

18 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 stainless steel.

22 Cross Reference Guide - SSB Bearing Table What is Bearing Preload? Ball bearings, composed of multiple parts working together as an assembly, are designed with clearances that permit freedom of motion. Clearance is not necessarily a result of manufacturing precision bearings may be designed with greater clearance to accommodate higher axial loads or minor axial misalignment. As clearance and manufacturing tolerances stack up, a bearing assembly will begin to experience axial and radial play. Bearing Preload is the process of adding a sustained axial load, independent of external loads, to the bearing. An axial preload ensures constant contact between the ball complement and bearing races reducing or eliminating both modes of play. Spring Preload, a versatile execution of Bearing Preload, utilizes single turn Wave Springs to add the necessary preload forces despite dimensional variation and thermal expansion. Properly preloading a bearing can increase its life and eliminate the vibration and noise that results from specified clearance, manufacturing precision, and wear. Bearing without a preload: Clearance between components can cause vibration and wear. Bearing with a preload: The ball complement and bearing races mate reliably reducing or eliminating vibration and wear.

The springs energize the vanes against the bore for better sealing. Detent Preload Smalley Linear Springs are used to load pins that are positioned inside grooves so a rotating element can detent to specific positions. The springs are designed to exert a precise load to give the rotation a desired resistance. Manufactured in USA Smalley (87)

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 stainless steel. However, Smalley can make them to order in nearly any size or material.

41 Spring & Fatigue Testers 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.) Spring Tester. 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 (87)

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 custom 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 custom designs Easy installation and removal Request FREE samples Get free samples of any standard catalog item at Or use form on page of this catalog.

43 Ring Introduction Other Ring Types & Custom 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. WaveRing 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. Custom Rings A major segment of Smalley manufacturing is in custom or prototype retaining rings. Common Smalley customs 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 small. Prototypes can be quickly and economically produced to test a design; in days, not weeks.

47 Ring Applications A. Rubber Boot B. Pneumatic Fitting C. Conduit Connector D. Gear Bracket 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 (87)

48 Ring Applications H. Pressure Gauge G. Bike Lock J. Actuator Valve I. Gear Assembly K. Pneumatic Clutch L. Hose Fitting 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 heavyduty 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 smalley.com No-Tooling-Charges For Customs

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 smalley.com No-Tooling-Charges For Customs

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.

77 ID/OD Lock ID/OD Retaining Ring Lock Spirolox Retaining Rings can operate in an internal and an external groove simultaneously. Spiral type retaining rings have many benefi ts for the ID/OD Lock, these bene fits include concealed fastening, no required assembly tooling and a 60 rotational capacity. With a Spirolox Retaining Ring, the application is tamper-proof and aesthetically pleasing. In this featured application, the retaining ring is initially installed in the housing groove. When the mating component in the assembly is added, the retaining ring compresses into the groove. The groove is deep enough for the rings radial wall to fit into as the component slides into position. Finally, when the grooves meet, the retaining ring snaps into the shaft groove (groove depth equals / the retaining rings radial wall) while still in the housing groove. In the pneumatic fitting and hose connector applications depicted below, a -Turn retaining ring without removal notches or an o ffset, creates an ID/OD lock, permitting the 60 rotation of the nut.

103 Laminar Seal Rings A Smalley Laminar Seal Ring set is a metallic labyrinth seal consisting of multiple rings in a groove. The arrangement and the specific orientation of the rings are dictated by the application and the severity of the environment. There are 6 series of standard imperial and Metric Laminar Seal Ring configurations from which to select. 8 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 imperial and 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. 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. Advantages of Laminar Seal Rings No friction with other rotating components, ideal for high speed applications. Prevent dirt and splash water from contaminating components. When used in conjunction with other seals, Laminar Seals provide a primary seal against severe contamination, before the contaminants come in contact with the secondary seal. Sets of multiple rings provide an efficient labyrinth seal. Rings may be produced from a wide variety of alloys to withstand more severe conditions including higher temperatures and corrosive environments. As a metallic mechanical seal they can outperform rubber seals in durability and life expectancy. The change from rubber to metal reduces the need for frequent seal replacement.

104 Laminar Seal Rings 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 comprised of single-turn rings in either rings per set or 5 rings per set. APPLICATIONS: ring sets protect components from low dirt and low splash water contamination. 5 ring sets provide a better labyrinth seal to protect components from medium dirt and medium splash water contamination. Double -Turn Laminar Seal Rings The sets are comprised 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. APPLICATIONS: ring sets protect components from medium dirt and medium splash water contamination. ring sets provide a better labyrinth seal to protect components from heavy dirt and heavy splash water contamination. 0 smalley.com No-Tooling-Charges For Customs

105 Laminar Seal Ring Applications A. Coupling B. Bearing Protection C. Pulley Idler D. High Speed Spindle A. Coupling The seal arrangement in this assembly has been custom designed for optimum protection against contamination. Gases build up pressure in a center cavity, protected on both ends from contaminants entering. B. Bearing Protection The ring set protects the ball bearing from contaminants like dirt and water. The seal retains grease/lubricant and prevents contaminates from penetrating into the critical components of the assembly. C. Pulley Idler The ring set designed in this application extends the life of the ball bearing by keeping contaminants from penetrating the precision bearing surfaces even though the bearing itself is sealed. When the shaft rotates only the groove ring rotates while the housing rings remain stationary. D. High Speed Spindle The QS series has been designed into the spindle assembly to protect the tandem bearings against corrosive elements. Though it is not the primary seal in the assembly, it is designed as the final seal protecting the bearings. All rings in the set will cling to the shaft due to the high rotational speed of the main spindle. Manufactured in USA Smalley (87)

111 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. n 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. n 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. n 6 has a silver-gray color. 7-7 PH Condition CH900 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 CH900. As a result, the material may be subjected to a temperature of 650ºF ( C) without a loss of spring properties. 7-7 PH Condition CH900 exhibits magnetism similar to high carbon steel. n 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. Manufactured in USA Smalley (87)

112 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.

113 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. Zinc Plating Zinc Plate, ASTM B6, Type V, Fe/Zn 5, SC (Colorless) Zinc Plate, ASTM B6, Type VI, Fe/Zn 5, SC (Colored Chromate) Zinc plating is used on carbon steel to increase the corrosion resistance of the product. Zinc plating is often used as a cost effective and ecologically friendly alternative to Cadmium plating. Our standard Zinc plating, Type V and Type VI, are RoHS compliant. The thickness level of the plating is controlled by the service condition number (SC number) which can be designated by the customer. Zinc plating does not guarantee coverage between the turns of multiple turn rings. The process does subject the ring to the possibility of hydrogen embrittlement. Smalley offers stainless steel as a preferable option to both cadmium and zinc plating. 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 (87)

114 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, crosssection and chemical composition. 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 cross-section, not a single point as in a hardness test. A B B A smalley.com No-Tooling-Charges For Customs

115 Spring Design 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. LOAD (P) WORK HEIGHT 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. Custom Springs Finding the right spring can be as easy as selecting a standard catalog item.

118 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. 8 smalley.com Figure No-Tooling-Charges For Customs

119 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) * 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. 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. Figure a Figure b 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. Manufactured in USA Smalley (87)

120 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 50 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. 0 smalley.com No-Tooling-Charges For Customs

121 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 (87)

122 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. MAXIMUM RADIUS ON BOTTOM Table SHARP CORNER 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. Where: b = Radial wall (in) d = Groove depth (in) Example:. WH-00 Maximum Chamfer =.75( ) =.00 in Maximum Radius =.5( ) =.07 in Formula: Maximum Chamfer =.75(b - d) (on retained component) Formula: Maximum Radius =.5(b - d) (on retained component) MINIMIZE DISTANCE MINIMIZE DISTANCE MAXIMUM CHAMFER MAXIMUM RADIUS d b 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 Where: z = Edge margin (in) P = Load (lb) D G = Groove diameter (in) S Y = Yield strength of groove material (psi), Table d = Groove depth (in) K = Safety factor ( recommended) Example:. VS-5. Groove material yield strength = 0,000 psi. Safety factor =. Load =,000 lb Shear Bending () 000 (6).0 (000) z = z = 0,000 (.06) π 0,000 (.06) π z =.059 in z =.05 in Therefore the minimum edge margin that should be used is.059 inv smalley.com No-Tooling-Charges For Customs

123 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: 600 V E I g N = (π ) Y γ A R 5 M 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 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.

In special applications it is sometimes favorable to have the retaining ring reverse, left hand wound.

125 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: Where: For external rings For internal rings E b (D S E = S - D I ) S C = E b (D O - D H ) (D I + b)(d S + b) (D O - b)(d H - b) 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.

127 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 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) K = Safety factor ( recommended) 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 5 *PATENT PENDING Manufactured in USA Smalley (87)

134 Glossary Bore Diameter: (See housing diameter) Centrifugal Capacity (N): A mathematical expression for determining the speed (in revolutions per minute, rpm) at which a retaining ring will lose cling on the groove. Cling: A value that signifies the amount of interference fit between a retaining ring and its groove. Crest-To-Crest: Term used to identify a Smalley Flat Wire Compression spring in a Series configuration, having a sinusoidal waveform. The wave contour in each 60 turn provides a peak to valley relationship that decreases spring rate proportionally to the number of turns. Dish: This ring dimension is the height difference in the ring cross section s axis of symmetry between O.D. and I.D. as illustrated below: DISH Edgewinding: Smalley s manufacturing method of circle coiling rectangular section flat wire on edge. Free Gap: The distance between the Free Ends of a ring or spring as it rests in its free state. FREE I.D. FREE GAP RESTRAINED TO GAGE INSTALLED GAP Housing Diameter (DH): Also referred to as bore diameter. This dimension represents the inside diameter of the assembly where an internal retaining ring is installed. FREE I.D. FREE GAP RESTRAINED TO GAGE INSTALLED GAP Hydrogen Embrittlement: A condition where hydrogen is absorbed within the internal grain structure of metal tending to make it susceptible to cracking and failure, particularly under sustained loads. Environments such as hydrogen sulfide (HS) or processes such as electroplating or pickling can induce hydrogen embrittlement. Installed Gap: (see Free Gap) This ring dimension is the distance between the ring ends while the ring is restrained at a specific gage diameter. Recommended as a more precise method of control over a free gap. Installation Stress (SC) or (SE): Mathematical expression based on a radial strain. Useful in determining how far a Spirolox Retaining Ring can be expanded or contracted during installation. Keystone: Derived from the definition of a wedge shaped stone. This term, illustrated below, refers to the wedge shaped cross section as a result of edgewinding flat wire. Left Hand Wound: Also referred to as reverse wound, design term signifying the counter-clockwise winding direction of a pitched coil. Hardness: The resistance of a material to plastic deformation, usually by indention. Helix: (see pitch) Hoopster: Term used to identify the style of retaining ring with minimal radial projection and shallow groove depth. LEFT HAND WOUND RIGHT HAND WOUND Linear Spring: Term used to identify a straight length of flat wire having a sinusoidal waveform. Used as a compression spring in both axial and radial applications. Material Thickness (t): Also referred to as wire thickness. This dimension, as illustrated below, is useful in determining the overall ring thickness.

135 Glossary Misalignment: Also referred to as skew, this ring dimension is the radial variance of a multiple turn retaining. Removal Notch: Also referred to as a radius notch or scallop, this standard Spirolox Retaining Ring design feature is used to facilitate removal of the ring from its groove by means of a screwdriver or similar type tool. MISALIGNMENT Modulus of elasticity (E): A measure of the rigidity of a material. Nested: Term used to identify a Smalley Flat Wire Compression Spring in a Parallel configuration, having a sinusoidal waveform. The wave contour in each 60 turn matches (nests), increasing the spring rate proportionally to the number of turns. W.H. f H N Z Residual Stress: Stress induced by a cold working process such as edgewinding. It may or may not be beneficial, depending upon the application. Reverse Wound: (see left hand wound) Right Hand Wound: Design term signifying the clockwise direction that a Spirolox Retaining Ring is normally wound. (also see Left Hand Wound) Number of Turns (n): The number of 60 turns of flat wire formed in a retaining ring or wave spring. Offset: As illustrated below, this design feature is a bend in the material at the gap. This provides flat and parallel surfaces for ease of installation. t Ring Thickness (T): Total thickness of an edgewound retaining ring. It may be determined by multiplying the material thickness by the number of turns and adding in the keystone value. RING THICKNESS RIGHT HAND WOUND NO OFFSET Permanent Set: A ring that has been expanded or contracted to a point where its elastic properties have been exceeded and does not return to its original diameter is said to have taken permanent set. Pi-Cut Ends: Term signifying a particular ring design where the ends have been cut in an angular direction from the center of the ring as illustrated below. Pitch: Also referred to as helix, this ring dimension is the distance between two adjacent layers of the retaining ring. PITCH PI-CUT OFFSET Radial Wall (b): Width of a retaining ring when measured from inside to outside edge. Radius Notch: (see Removal Notch) Rod Diameter: (see shaft diameter) Safety Factor (K): Mathematical constant used in many design formulas to account for theoretical inaccuracies. Scallop: (see Removal Notch) Shaft Diameter (DS): This dimension represents the outside diameter of the assembly where an external retaining ring is installed. Shear Strength (SS): An index of the quality of a material through a mathematical expression which divides the force required to shear a material by its cross-sectional area. Stress Relieve: Low temperature heat treatment for removing any residual stresses induced by edgewinding and/or forming. Tensile Strength: An index of the quality of a material through a mathematical expression which divides the material s load capacity in tension by its original cross-sectional area. Particularly accurate for spring steels, as there is only a small difference between ultimate tensile strength and yield strength. Thrust Load Capacity (PG) or (PR): 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 (PR) or groove thrust load capacity (PG). Yield Strength (Sy): The stress at which a material exhibits initial plastic deformation. WAVO: Single turn round wire wave spring. Manufactured in USA Smalley (87)
