R+W Antriebselemente
The low-wear, flexible gear couplings from R+W are used in a wide variety of industries. Particularly in heavy-duty operation – such as on the high torque shafts of mixers, rolling mills, crushers, test stands and conveyors – gear couplings transmit torques from 1,900 to 2,080,000 Nm with high torsional rigidity and low backlash. To ensure optimal performance, R+W manufactures both the coupling hubs and the flange sleeves with precise crowned gearing, made from high-strength steel.
Durable, reliable, and flexible: these characteristics make industrial couplings ideal for all applications that require maximum safety and performance in the face of constant and extreme loads. Engineers and operators across a wide range of industrial sectors are aware that machine component failures and downtime drive up cost and, in the worst cases, can lead to accidents – making proper industrial coupling selection critical.
The main advantages of elastomer 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 optimizes the entire drive train and exhibits important characteristics, such as vibration damping, torsional stiffness, and thermal stability.
