Installing the torque arm at helical-bevel gear units and helical-worm gear units

When mounting the torque arm to a helical-bevel gear unit or helical-worm gear unit, it is important to ensure that it is carried out correctly, especially with regard to the stresses.

The following figure shows a secured bushing with a support on both sides.

The reamer bolt or screw must be held in a fork-like design without tensions. On the one hand, the bolt should have little radial clearance to the bushing to keep the impact load low during changeover, but large enough to prevent a distortion of the drive during standstill.

Avoid axial tension on the bushing, especially as this may cause tension on the drive.

Even self-designed torque arms should be fastened this way without tension.
