Alignment
Alignment
The gear unit housing has machined surfaces (alignment surfaces) to help you align the unit
horizontally in the longitudinal axis. The machine shaft determines the horizontal mounting
position in the transverse axis.
DANGER
Risk of fatal injury from ying 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 specied 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 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.
