ELASTOMER COUPLINGS – DEFINITION, FUNCTION AND PROPERTIES

The elastomer coupling is part of the claw coupling group, but it has an essential additional component: an elastomer insert placed between the two hub halves. This elastomer insert is the central element of the elastomer coupling. It transmits torques from 0.5 to 25,000 Nm without play and compensates for misalignments of axial, lateral and angular shafts. Chosen in the right version and hardness, the elastomer insert optimizes the entire drive chain and guarantees important elements such as vibration absorption, torsional rigidity and temperature resistance. In the particular “ATEX” case, electrical conductivity is also an important characteristic. The compression of the elastomer insert ensures no necessary play, two extremely precisely manufactured hubs with concave claws guarantee precise concentricity. There are different versions with clamping cone. Good absorption has a positive effect on service life, especially in installations subject to frequent shocks, changes or vibrations.
