Claw coupling

torsionally flexiblemotorgearbox

Torsionally flexible claw couplings consisting of two hubs and a set of rubber elements that fit radially between the claws of the two hubs. Rated torque: 19 Nm to 62,000 Nm, ATEX compliant. The N-EUPEX claw coupling is available as a catalogue standard in 23 sizes with a rated torque of between 19 Nm and 62000 Nm. The coupling is suitable for use at ambient temperatures of between -30°C and +80°C. By using alternative elastomer elements, the permissible ambient temperature range can be extended to between -50°C and +100°C. Frequently, the coupling is used to connect the motor to the gear unit input shaft. The coupling is suitable especially for drives with uniform to average dynamic loads. » Adapters and hubs: Grey cast iron EN-GJL-250 » Brake disks: EN-GJS-400 spheroidal graphite cast iron or S355J2G3 steel » Brake drums: Grey cast iron EN-GJL-250 » Low-temperature application: Shock loads in the drive caused by e.g. starting of drives with large masses to be accelerated (e.g. in fan drives) result in high component loads, particularly at low temperatures. For such applications a particularly robust coupling series must be selected.
