1 Quality Precision Reliability Precisely what you need, Precisely when you need it

2 Regarding quality extremely pleased with Belden s products Belden offers the best product for the least cost. Regarding capabilities We had a problem with the boots on the universal joint assemblies from our previous supplier. Belden engineers came here to meet with our engineers to resolve the problem and redesign the parts. The boot redesign was included on our assemblies within days. We have had no problems since. Regarding delivery the delivery time has been reduced since I first started doing business with Belden. Belden prepared themselves by stocking many of our frequently ordered parts. Regarding delivery Belden cut their delivery in half by planning for our orders and stocking components in anticipation of our next release. Regarding capabilities We now buy other components from Belden. A Belden Sales Rep came to our facilities to look at how we were operating our equipment. She took part samples back to your [Belden s] engineering department. They suggested some changes and offered to make the parts for less than we were getting them before. We re getting a superior assembly that s cost effective.

10 Custom Universal Joints and rive Shafts Uniform speed ratio between driving and driven shafts Quick-change feature available Custom designed to meet customer specifications Belden design engineers can specify a universal joint assembly to meet the most unique requirements. In addition to the high-quality alloy steel standard of Belden universal joints, assemblies can be manufactured from a variety of materials, including various grades of stainless steel. Belden s capabilities allow us to provide precise, reliable and durable universal joints for customers exact application specifications. Quick/Change Feature A quick-change feature is available on our custom universal joint drive shaft assembly which allows the universal joint to be quickly removed and replaced without tools. This is an essential feature when machine downtime is crucial. The quick-change universal joint consists of two back-to-back single universal joints connected with a spring loaded intermediate shaft. Pinning of outer yokes is not required because the spring tension on the intermediate shaft holds the quick-change universal joint secure at each end. End Hub Configurations Belden offers a wide variety of end hub configurations. The six most conventional hub types, in either male or female, are available in metric or inch sizes. Solid hubs are also available. Custom universal joints and drive shaft assemblies are our specialty. K SW 1 M E S T F Keyway Hexagonal Bore Thread Spline Square 1

15 Universal Joint Boot Covers Added protection in adverse conditions Increases the lifetime of a Universal Joint when filled with Lubricant If the universal joint assembly is going to operate in an atmosphere that is polluted with chips, dirt, acids and/or other abrasives, it is highly recommended that boots be specified on the original assembly. Boots play an important role in protecting the joint and keeping it fully lubricated. Proper lubrication will prolong the useful life of an assembly by a factor of as much as five.

23 Terminology Universal Joint Pin and Block Universal Joint Cross and Bearing Universal Joint Needle Bearing Universal Joint Torque Axial, Parallel & Angular Misalignment A mechanical device that can transmit torque and/or rotary motion from one shaft to another at fixed or varying angles of intersection of the shaft s axis. Also know as the Cardan or Hooke joint, the pin and block is the simplest unit available. It allows for a more positive transmission of rotating power or torque than conventional flexible couplings. A forged cross with a needle bearing connection provides minimal backlash and precise positioning without compromising torque capacity. Needle bearings are installed at the pin ends to reduce backlash and increase precision and RPM capability. Torque is the force that causes rotation. Operating torque is the amount of torque that is transmitted during normal operation. Torque is commonly expressed in pound inches (lbf-in), pound-feet (lbf-ft), or Newton-meters (Nm). T [lbf-in] = Power [ HP] x 6324 T [Nm] = Power [kw] x 955 RPM RPM Axial misalignment is the amount of axial movement (end play) between the shafts, which is typically caused by motor vibration. Parallel misalignment is the offset between driving and driven shaft. Angular misalignment is the angle at which the shafts intersect. Axial Misalignment Parallell Misalignment Angular Misalignment Torsional Stiffness Zero Backlash uty Cycle Torsional stiffness is the degree of resistance against twist. It is commonly expressed in pound-inch/radian (lbf-in/rad) or Newton-meter/radian (Nm/rad) Pound Inch/Radian (lbf-in/rad) = 1 Newton-meter/Radian (Nm/rad) Pound Inch/egree (lbf-in/grad) = 1 Pound Inch/Radian (lbf-in/rad). Zero backlash refers to the amount of radial play within a coupling assembly. The load on a universal joint is either intermittent or continuous. Under most operating conditions, a joint s intermittent load capacity is greater than its continuous load capacity. Unit Conversion 1 lbf-in = Nm 1 Nm = lbf-in 1 HP =.7457 kw 1 Inch = 25.4 mm 1 lbf =.4536 kg 1 lbf-ft = Nm 1 Nm = lbf-ft 1 kw = HP 1 mm =.394 Inch 1 kg = lbf Constant Velocity In order to achieve constant velocity operation, driving & driven shaft are required to be aligned parallel. RIGHT WRONG Yoke Orientation When creating a double joint by connecting two single joints with a shaft, the yokes of the inbound joints are required to be aligned as shown below. RIGHT WRONG 23
