R+W Elastomer Insert Coupling - Series EK

FOR SMOOTH RUNNING: ELASTOMER INSERT COUPLINGS FROM R+W

The main advantages of elastomer insert couplings include vibration damping, easy installation, zero backlash transmission, and electrical isolation. Whether for machine tools, packaging machines, automation systems, printing machines or general mechanical engineering - the uses for elastomer couplings are as diverse as their requirements.

Elastomer couplings are part of a wider group, known as jaw couplings, the key component of which is an elastomer segment inserted between two hub halves. This elastomer insert is 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. When properly selected for size and hardness, the elastomer insert optimises the entire drive train and exhibits important characteristics, such as vibration damping, torsional stiffness and thermal stability. Electrical conductivity is also an important feature of the special ATEX certified version, providing a path to ground for any electrostatic charges, and eliminating the potential for sparking when used in hazardous environments. Preloading of the elastomer insert ensures backlash free transmission, and the precision machining of the two hubs with curved drive jaws guarantees concentricity for smooth running. The damping ability of elastomer couplings can have an especially positive effect on the service life of adjacent equipment, especially in case of vibration, shock loading and dynamic motion.
