Elastomer couplings

VARIODRIVE offers the robust claw couplings from R+W Couplings. The main advantages of claw couplings include vibration damping, easy installation, backlash-free transmission and electrical isolation. Whether for machine tools, packaging machines, automation systems, printing machines or mechanical engineering; the applications of these precision couplings are as diverse as their requirements.

Claw couplings are made up of three parts, the main component of which is an elastomeric star placed between two hub halves. This elastomeric star is the heart of the claw clutch. It is backlash-free, transmits large torque moments and captures axial, lateral and angular misalignments. When the right size and hardness is selected, the elastomer star optimises the entire driveline. In doing so, it dampens vibrations and possesses proper torsional rigidity. The preload of the elastomer star ensures backlash-free transmission, and the precision machining of the two hubs with curved concentric pitch parts ensure smooth rotation. The damping capability of claw couplings can have a particularly positive effect on the service life of adjacent equipment, especially under vibration, shock loads and dynamic movements.
