5.2 CHANGES OF COUPLING
DANGER!
A change at the coupling parts is only permitted
after having checked with the manufacturer.
For making the shaft bore by the user, please pay attenti-
on to the following items:
• The maximum admissible bore diameter d1 + d2 (see
Technical Data) must not be exceeded. In case of
disregard of these values, the coupling might break.
Flying fragments can cause serious personal injuries.
This concerns all materials.
• The predetermined planning and rotation accuracy of
the manufacturer must be adhered to.
• For making the finish bore, a careful alignment must be
made.
• For the axial safety device, please use a locking screw.
• If using a locking screw, following tightening torques
must be kept (see table):
5.3 MOUNTING
INDICATION!
Before mounting, we recommend to check the bores,
shaft, hub and feather key for accuracy.
A heating of the hubs to approx. 80°C eases the fitting
onto the shaft.
DANGER!
In order to avoid burnings by the contact with ted
hubs, please wear safety gloves.
CAUTION!
Please pay attention to the danger of ignition in
hazardous areas.
ATTENTION!
When mounting the coupling, please ensure that the
dimension E (see Technical Data) must absolutely be
kept, so that the gear ring is axially movable during
operation. Disregard might lead to damages.
• After mounting of the hubs to the shafts of the drive and
load side, the dimension “E” must be adjusted by relo-
cation of the aggregates or the hubs on the shafts.
• Shafts with inserted feather key and a smaller diameter
than the inner diameter of the gear ring dh may reach
into the gear ring. The distance between the shafts must
not be lower than 50% of the dimension “E”.
• For securing the hubs by relocation, please tighten the
locking screw with corresponding starting torque
(Table 5.3).
