Gear Units Equipped With Solid Shaft; Gear Units With Hollow Output Shaft - BONFIGLIOLI HDP Series Installation Use And Service Manual

5.1.2 GEAR UNITS EQUIPPED WITH SOLID SHAFT

When installing external parts do not use hammers or other tools to avoid the risk of
damaging the gear unit shafts and supports. On the contrary, proceed as shown in the
following diagram, ideally preheating the part to be coupled. For further details refer to
heading 5.3
Bolt (1) and spacer (2) are to be supplied by customer.
To minimise the loads on the shaft bearings, when mounting transmission elements with asymmetrical

5.1.3 GEAR UNITS WITH HOLLOW OUTPUT SHAFT

Before installing the gear unit by means of its hollow low speed shaft, perform the following operations:
1. Use petrol to remove any anti-corrosion coatings from the hollow shaft and the machine shaft.
In this case it is essential to avoid all contact between petrol and the shaft oil
seals.
2. Check the hollow shaft and the machine shaft to ensure that the seats and edges are
undamaged.
To facilitate mounting hollow shaft gear units onto the machine's driven shaft, proceed as indicated in
the diagram below. Also refer to Annex 3 of this Manual for dimension information on customer's shaft.
