Cover plate of the fan
A detailed view of the gear unit can be obtained from the drawings in the gearunit documentation.
For gear units fitted with a fan, sufficient space must be allowed for air intake when
fitting the safety guards for the coupling or other components.
The correct distance is given in the dimensioned drawing in the gearunit
documentation.
It must be ensured that the cover plates are correctly fastened. The cover plates must
be protected against damage from outside. The fan must not come into contact with
the cover plates.
The cooling effect is considerably reduced if the fan or the housing surface are dirty
(see section 10, "Maintenance and repair").

Couplings, clutches
As a rule, flexible couplings should be provided for the drive of the gear unit. The fitted fan must not cause
axial forces exceeding the maximum forces agreed in the contract.
For maintenance and operation of the couplings, refer to the specific operating instructions for the
coupling.
When installing the drives, make absolutely certain that the individual components are
accurately aligned in relation to each other. Inadmissibly large errors in the alignment
of the shaft ends to be connected due to angular and axial misalignments result in
premature wear and/or material damage.
Fitting the motor on the motor bell housing ensures an exact alignment.
