NOTICE
Use of incorrect attachment points
Use of incorrect attachment points may result in damage to the gear unit.
• Only attach the gear unit at the lifting eyes provided for this purpose.
• Do not use the pipework to move the gear unit. The pipework must not be damaged.
• Do not use the threads in the end faces of the shaft ends for attaching lifting equipment to
transport the gear unit.
• Lifting equipment must be adequately designed to accommodate the weight of the gear
unit.
5.7 Shaft-mounted gear unit with ange coupling
Requirement
Ensure that in the area around the shrink disk seat, the bore of the hollow shaft and the machine
shaft must be absolutely free of any grease. 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.
Mounting a shaft-mounted gear unit with ange coupling
In order to avoid damaging the gear unit by canting it and by unevenly tightening the tensioning
screws proceed as follows.
1. Before tightening the tensioning screws, ensure that the anges are centred with respect to
one another.
2. Tighten the tensioning screws crosswise and evenly with the full torque.
3. Avoid deforming or distorting the gear units when tightening the tensioning screws.
Note
Replace any bolts that are no longer t for use by new bolts of the same strength class and type.
Further information
You can nd additional information about the tightening torque of the tensioning screws in the
dimension drawings in the coupling operating instructions.
