FLENDER Standard Couplings Flexible Couplings — RUPEX Series © Siemens AG 2015 General information ■ 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 connection. 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.
■ Technical data Power ratings 8 All article numbers listed below apply to standard buffers of NBR material in the 80 ShoreA variant. 1) The maximum speed of the respective type must be noted. For further information on permissible shaft misalignment, please see the operating instructions.
