Gear units – Manual with installation instructions
26 B 1000 en-3921
Do not distort the support when installing push-on gear units with a torque support. Tension-free
mounting is aided by the rubber buffer (Option G or VG).
Figure 9: 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. For screw fastenings with standard thread, then rotate the fastening nut half a
turn in order to pre-tension the rubber buffer. Greater pre-tension is not permissible.
Explanation
1 Always support torque support
on both sides
Figure 10: Attaching the torque support on bevel gear and worm gear units
Tighten the fastenings of the torque support with the correct torque (see chapter 7.3 "Screw tightening
torques")and secure them against loosening, e.g. with Loctite 242 or Loxeal 54-03.
3.7 Fitting a hollow shaft with shrink disc (Option: S)
Risk of damage to the gear unit if the shrink disk is installed incorrectly
• Do not tighten the tensioning bolts if the solid shaft is not installed. This would permanently deform
the hollow shaft.
Hollow shafts with shrink discs must be protected from dust, dirt and moisture. NORD recommends
option H/H66 (see chapter 3.9 "Fitting the covers (option: H, H66)").
