3.21 Torque supports (Option: D, ED, MS)
NOTICE!
Risk of gear unit damage if the torque arm is installed incorrectly
• 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.
• The torque arm is not suitable for transferring transverse forces.
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 permissible.
For helical gear units with motor adapters, the torque support is located opposite to the motor adapter.

Figure 22: Permissible installation tolerances of the torque arm (option D and ED) (schematic diagram)
The length of the torque support (Option: D) can be adjusted within a certain range.
The gear unit is aligned horizontally by means of the threaded bolt and the nuts of the torque arm and
secured with lock-nuts.
Tighten the fastenings of the torque arm with the correct tightening torques (please see chapter 7.4
"Screw tightening torques")and secure against loosening (e.g. Loctite 242, Loxeal 54-03).
The Option ED torque support has an integrated elastic element and cannot be adjusted in length.
