Demounting - Siemens FLENDER H SH Series Assembly And Operating Instructions Manual

6.4.3

Demounting

• Remove the axial securing device from the hollow shaft.
• If frictional corrosion has occurred on the seating surfaces, rust­releasing agent may be used in order
to facilitate forcing off the gear unit. The rust releaser can be injected through the pressure­oil
connection (see Fig. 41), e.g. using a pump.
• When the rust­releasing agent has taken effect, pull the gear unit off with the device (see figs. 43
and 44).
• Removing the gear unit from the driven­machine shaft can be done locally as follows:
─ using forcing screws in an end plate (see Fig. 44) or
─ using a central threaded spindle or
─ preferably using a hydraulic lifting unit ("Lukas").
The end plate and/or the auxiliary plate for forcing off the gear unit are not included in our
delivery.
Each of the two end faces of the hollow shaft is provided with 2 threaded holes (for dimensions,
see fig. 45) to receive bolts for fastening the end plate to the hollow shaft.
