Further information
Further information about removing the corrosion protection can be found in the operating
instructions BA 7300 in the complete documentation for the gear unit.
Additional information on how gear units should be attached which, as a result of their weight,
require a crane or lifting gear, is provided in chapter Application planning (Page 45).
If the gear unit is to be transported with mounted parts and components, then it may be
necessary to use additional attachment points. The position of these attachment points can
be found in the dimension drawing in the complete documentation for the gear unit.
5.3.2.1 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.
