Function
The motor torque is transmitted to the hub on the drive side via
the shaft-hub connection, which is mostly designed as a keyway
有限公司nnection. With the aid of elastomer buffers mounted on steel
pins, the torque is conducted to the hub on the output side.
The hub on the output side further transmits the torque to the
driven machine or a gear unit located in between. Because of
the primarily compression-loaded buffers, the coupling has a
progressive torsional stiffness.
