The elastomer insert is at the heart of the elastomer coupling. It transmits torques from 0.5 to 25,000 Nm without backlash, and compensates for axial, lateral and angular shaft misalignment. We will be discussing alternatives to keyways in motion systems. The age-old tradition of using shaft keys in mechanical drives has served the power transmission industry well for many years. Today’s increasing demands for speed, precision, and small size have changed the standard for shaft locking devices, and challenged motion components manufacturers to develop new methods of keyless shaft locking for dynamic loading.
