5.6.1 Assembly
Measures to be taken prior to assembly
CAUTION
Risk of injury due to chemical substances
Observe the manufacturer’s guidelines on how to handle lubricants and solvents.
Wear suitable protective clothing.
Improper use can damage the gear unit. Be sure to take the following precautions:
• Use a suitable cleaning agent to remove the corrosion protection from the hollow shaft and
the machine shaft.
• Inspect the hollow shaft and machine shaft for damaged seats and edges.
• If necessary, rework the components with an appropriate tool and then clean them again.
NOTICE
Risk of damage to shaft sealing rings
Aggressive chemical cleaning agents may cause damage to shaft sealing rings.
Do not allow the cleaning agent to come into contact with the shaft-sealing rings.
Note
The bore of the hollow shaft and the machine shaft must be free of any grease
Make sure that the hollow shaft bore and the machine shaft are completely free of grease in the
area around the shrink disk seat. The reliability with which torque is transmitted depends to a
large extent on this.
Do not use any contaminated solvents or soiled cleaning cloths, nor any cleaning agents that
contain oil (such as petroleum or turpentine) to degrease the surfaces.
