6.5 Fitting a shaftmounted gear unit with hollow shaft and parallel keyway
The end of the drivenmachine shaft (material C60+N or higher strength) must be provided with a parallel
key to standard "DIN 6885" Part 1 Form A. There should also be a centering hole to standard "DIN 332"
Form DS (with thread) on the end face. For the connection dimensions of the drivenmachine shaft, see
dimensioned drawing in the gearunit documentation.
6.5.1 Preparatory work
To facilitate demounting (see item 6.5.3), we recommend providing a connection for pressure oil on the
end of the drivenmachine shaft end, which is drilled through to the hollowshaft recess (see figure 25). This
connection may also be used for supplying rustreleasing agent.

DANGER
Risk of explosion
Danger to life through ignition of solventagent vapours or any other potentially explosive atmosphere
during cleaning work.
The gear unit must not be cleaned in a potentially explosive atmosphere.
– Avoid ignition sources.
– Do not smoke.
– Ensure adequate ventilation.
• Remove the corrosion protection from the hollow shaft and drivenmachine shaft with a suitable
cleaning agent.
CAUTION
Risk of injury through chemical substances
Observe manufacturer’s instructions for handling lubricants and solvents.
Wear suitable protective clothing.
NOTICE
Material damage
Risk of damage to the shaftsealing rings through chemically aggressive cleaning agents.
The cleaning agent must in no way be allowed to come into contact with the shaftsealing rings.
