Figure 3-8: Gear unit mounted to shaft without a shoulder using the fastening element
A gear unit can be dismantled from a shaft with shoulder using the following device, for example.
Figure 3-9: Dismantling using dismantling device
When mounting push-on gears with torque supports, the support must not be distorted. Tension-
free mounting is aided by the rubber buffer (Option G and/or VG).
Figure 3-10: Mounting the rubber buffer (Option G and/or VG) on parallel shaft gear units
To fit the rubber buffer, tighten the screw fastening until there is no play between the contact
surfaces when there is no load. Then turn the fastening nut (only applies for adjusting threads)
half a turn in order to pre-tension the rubber buffer. Greater pre-tension is not permissible.
Secure the screw fastening against coming loose, e.g. with Loctite 242 or a second nut.
