3 GNRL INFORMTION R+W LSTIC JW COUPLINGS SHFT MISLIGNMNT lateral angular axial FUNCTION The equalizing element of the K coupling is the elastomer insert. It transmits torque without backlash or vibration. The elastomer insert defines the characteristics of the entire drive system. Backlash is eliminated by the press fit of the elastomer into the hubs. Through variation of the Shore hardness of the elastomer insert, the coupling system can be optimized for the ideal torsional characteristics.
