ROTEX® coupling

Mounting the coupling
  1. NOTICE! Improper assembly may damage the hubs [1][2]. Possible damage to property. Heat the hub to about 80 °C to facilitate mounting. Mount the hubs [1][2] onto the input and output shafts [3][4].
  2. Insert the spider [5] or DZ elements into the cam section of the input and output hubs [1][2].
  3. NOTICE! Improper mounting can damage the coupling. Possible damage to property. During assembly, it is essential to observe dimension E so that the spider remains axially flexible during operation. The dimension E is listed in the following table. Move the gear unit/motor in axial direction until dimension E is reached. If the gear unit and motor have already been installed permanently, set dimension E by moving the hubs [1][2] axially on the input and output shafts [3][4].
  4. Secure the hubs by tightening the set screws [6].
