Safety Warning When using Lovejoy products, you must follow these instructions and take the following precautions. Failure to do so may cause the power transmission product to break and parts to be thrown with sufficient force to cause severe injury or death. Refer to this Lovejoy Catalog for proper selection, sizing, horsepower, torque range, and speed range of power transmission products, including elastomeric elements for couplings. Follow the installation instructions included with the product, and in the individual product catalogs for proper installation of power transmission These couplings require no lubrication and provide highly reliable service for light, medium, and heavy duty electrical motor and internal combustion power transmission applications.

Spider / jaw couplings compensate for parallel, angular and axial displacements.

Request Information. Close Window. Measurement and Control Systems The torsional stiffness of the GS Series coupling provides zero backlashes needed for the accuracy for measurement and control systems. The low torques of these applications give the GS Series the ability to provide zero backlashes due to the elastomeric pre-stress. Servo and Positioning Drives The GS Series provides a zero backlash, flexible connection for servo and positioning drives.

Large stocks for quick delivery and in-house machine shop for exact fit to your application machinery. The flexibility of the drive ring allows the power transmission coupling to compensate for parallel, angular and axial displacements. Maximum shaft diameters of mm can be accommodated with maximum torques up to 15, Nm and maximum speeds of 19, rpm. Spidex power transmission couplings are torsionally flexible shaft couplings, the operating characteristics of which are two hubs with concave claws, transmitting the torque by meshing with an elastic involute gear ring. Due to the complete flexibility and ductility of the elastomer ring, it compensates for parallel and angular displacements as well as to absorb longitudinal movement of the shafts. The involute teeth of the elastomeric inserts are crowned in order to avoid edge pressure on the tooth flanks and so avoid undesirable axial thrust. The puncture proof spider coupling can be loaded extremely high since the elastic elements are submitted to compression and not to bending moments of force.

These couplings require no lubrication and provide highly reliable service for light, medium, and heavy duty electrical motor and internal combustion power transmission applications. Other features and benefits include: Fail-safe will still perform if elastomer fails. No metal to metal contact.

Application service factors for the Spidex® jaw coupling

Step 1. Determine the Service Factor Step 2. Determine minimum torque rating in lbs. This means Step 3. Multiply full load torque by the selected serv- the second motor requires a larger flexible coupling then ice factor the first. Ignoring the service factor can cause you to use a coupling too small for your application, leading to pre- Step 4. Determine shaft size mature wear and maintenance.
