6.5 Shaftmounting gear unit with hollow shaft and internal spline to DIN 5480
The shaft end of the driven machine must be designed with internal splines to DIN 5480. Furthermore,
a centring hole to DIN 332 Form DS (tapped) should be provided (for the connection dimensions of the
driven machine shaft, see dimensioned drawing in the gear unit documentation).
6.5.1 Preparatory work
To facilitate demounting (see also item 6.4.3.), we recommend providing a connection for pressure oil on
the end of the driven machine shaft. For this a hole must be drilled through to the hollow shaft bore
(see fig. 46). This connection may also be used for supplying rustreleasing agent.

6.5.2 Fitting
The gear unit must not be cleaned in an explosive environment.
• Remove the preservative agent from the hollow shaft and the machine shaft with a suitable cleaning
agent (such as benzine).
Do not allow the cleaning agent (e.g. benzine) to contact the shaftsealing rings.
Ensure adequate ventilation. Do not smoke!
Danger of explosion!
• Check the hollow and machine shafts to ensure that seats, teeth or edges are not damaged. If
necessary, rework the parts with a suitable tool and clean them again.
Coat with a suitable lubricant to prevent frictional corrosion of the contact surfaces.
