Alignment
Introduction
Depending on the order specification, the top of the housing has machined surfaces (alignment
surfaces) to assist with provisional alignment of the gear unit in the horizontal direction.
DANGER
Risk of fatal injury from flying fragments
Failure to align the unit with the required degree of accuracy can cause the shaft to rupture.
A ruptured shaft can result in serious or even fatal injuries.
Align the gear unit exactly so that it conforms to the specified alignment values.
Damage to the gear unit or its components or mounted parts is possible.
The accuracy of the alignment between the shaft axes largely determines the service life of the
shafts, bearings and couplings. Please therefore always endeavour to achieve zero deviation
in the alignment of the shaft axes (does not apply to ZAPEX couplings). In this context, please
also refer to the relevant operating instructions for further information about, for example, the
requirements of couplings.
Procedure
The gear unit can be equipped with alignment threads in the housing feet to make it simpler to
align.
Figure 5-1 Alignment surface
To align the gear unit by its alignment surface, proceed as follows:
1. For the precise position of the alignment surfaces, refer to the dimension drawings in the
complete documentation.
2. Note the values inscribed in the alignment surfaces.
3. Use these surfaces as a guide for aligning the gear unit horizontally to ensure that it will run
smoothly.
Further information
Further information and the precise position of the alignment thread are provided in the
dimension drawing in the overall gear unit documentation.
