3.8 Torque support
The length of the torque support can be adjusted within a certain range. The torque support
consists of a fork head with a bolt (1), a threaded bolt (2), a maintenance-free joint head (3) and
a fork plate with a bolt (4).
Assembly should be carried out from the side of the machine, in order to reduce the bending
moment on the machine shaft. Tension and pressure and installation upwards or downwards are
not permissible.
Distortion of the torque support during assembly or operation must be avoided, as otherwise the
service life of the output shaft bearings may be reduced. Torque supports are not suitable for the
transfer of radial forces, therefore they may only be used in combination with motor mounts or
couplings which do not transfer radial forces.
For helical gear units with motor mounts, the torque support is located opposite to the motor
mount.
The gear unit is aligned horizontally with the threaded bolt and the nuts of the torque support
and must be secured with lock-nuts.

3.9 Fitting shrink discs
Attention!
The operating instructions for the shrink disc must be observed.
