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 ( 33)
2. With a clamping hub:
– slightly loosen the clamping screw
– Fit coupling hub on the motor shaft using a center hole thread (do not mount by
hammer strokes, in order to avoid damage to the roller bearings in the motor).
– Observe mounting dimension m of the coupling hub ( 31).
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.
– The mounting process can be facilitated by lightly greasing or oiling the ring
gear sides or the hub sides. For this purpose, only use mineral oil−based
lubricants without additives, silicone−based lubricants, or vaseline.
5. Align claws of the motor−side coupling hub with its counterpart.
6. Slowly push on motor, and bolt on to the gearbox flange.
