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.
)
Note!
Tighten all screws to the coupling hubs and the motor fastening of
gearboxes in ATEX design with an intermediate strength screw retention.
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 (¶ 29)
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 (¶ 28).
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.
