General
Note!
Standard hubs, clamping hubs and clamping ring hubs are
maintenance−free.
We recommend carrying out a visual inspection of the star−shaped
spider/ring gear and the system parts within the inspection intervals.
Mounting the standard hub / clamping hub
1. Fit motor keyway (2).
– With some sizes a shorter featherkey is supplied, which is to be mounted. The
sizes concerned by this are shown on ( 25)
2. Push coupling hub onto the motor shaft, observe dimension m ( 25).
3. Secure coupling hub against axial movement using the fixing screw or clamping
screw (1).
4. Lay spider in the coupling claw on the gearbox side.
5. Align claws of the motor−side coupling hub with its counterpart.
6. Slowly push on motor, and bolt on to the gearbox flange.
