Shaft­mounted Gear Unit With Hollow Shaft And Shrink Disk; Fitting - Siemens FLENDER B3 E Series Assembly And Operating Instructions Manual

If the above values are exceeded, the housing, the hollow­shaft bearings or other
gear­unit components may be irreparably damaged. Before replacing the gear unit on
the machine shaft, always check the bearings for any signs of damage.
When using forcing screws or threaded spindles, the head of the thread pressing against the
driven machine should be rounded and well greased to reduce the risk of seizing at this point.
6.6 Shaft­mounted gear unit with hollow shaft and shrink disk
The end of the driven­machine shaft (material C60+N or higher strength) must have a centring means
to DIN 332 Form DS (with thread) in its end face (for connecting dimensions of the driven­machine shaft,
see dimensioned drawing in the gear­unit documentation).
6.6.1

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 (e.g. benzine).
Do not allow the cleaning agent (e.g. benzine) to contact the shaft­sealing rings.
Ensure adequate ventilation. Do not smoke!
Danger of explosion!
Check the hollow and machine shafts to ensure that seats and edges are not damaged. If necessary,
rework the parts with a suitable tool and clean them again.
The bore of the hollow shaft and the machine shaft must be absolutely free of grease
in the area of the shrink disk seat.
This is essential for safe and reliable torque transmission.
Do not use contaminated solvents or dirty cloths for removing grease.
