1. What is TND HDH Ringfeder Elastic Disc Coupling?

Coupling is a mechanical part that connects two shafts to accurately transfer power from the drive shaft to the driven shaft while compensating the mounting hole.

In particular, the TND HDH disc coupling is a flexible shaft coupling that transmits torque from the drive shaft to the driving bolt in a tangential direction on a common bolt circle. This torque is transmitted between the bolts through a series of thin, stainless steel discs, assembled into a set. The versatility of disc couplings comes from the deformation of the material between the bolts. Disc couplings are suitable for high-performance motion control applications and can typically handle speeds up to 12,200 rpm. minute.
