Fitting push-on gear units
Attention!
The bearings, gear wheels, shafts and housing may be damaged by incorrect fitting.
The push-on gear
unit must be fitted onto the shaft using a suitable puller, which
will not exert
damaging axial forces on the gear unit. In particular, do not hit the gear unit with a hammer.
Assembly and subsequent
dismantling is aided by
applying
an anti-corrosive lubricant
to the
shaft before fitting (e.g. Nord Anti-Corrosion Art.No. 089 00099). Excess grease or anti-corrosion
agent may
escape after assembly and
may drip off.
Clean these
points on the
output shaft after
a running-in time of approx. 24 hours. This escape of grease is not due to a leak in the gear unit.
Figure 3-4: Applying lubricant to the shaft and the hub
Note!
The gear unit can be fitted to shafts with
and
without
a
shoulder
using
the fastening element
(Option B). Tighten the bolt of the fastening element to the correct torque. (See Chapter 6.2 for
torque
values) For gear units
with
option H66,
the
factory-fitted closing cap must
be
removed
before assembly.
For shaft mounted
gear units with option
H66 and fastening element
(Option
B) the pressed-in
closing cap
must be pushed
out before
fitting
the
gear
unit.
The pressed-in closing cap may
be
destroyed during
dismantling. As standard
a second closing cap is supplied as a loose spare part.
After fitting the gear unit, fit the new / new condition closing cap as described in Section 3.11.

Figure 3-7: Gear unit mounted to shaft without a shoulder using the fastening element
A gear unit can be dismantled from a shaft with shoulder using the following device, for example.
Figure 3-8: Dismantling using dismantling device
When mounting push-on
gears with torque
support
s, the
support
must
not
be
distorted.
Tension-
free mounting is aided by the rubber buffer (Option G and/or VG).
Figure 3-9: Mounting the rubber buffer (Option G and/or VG) on parallel shaft gear units
To fit the rubber
buffer, tighten
the screw fastening until there
is
no play
between
the contact
surfaces
w

e
n
there
is no load.
Then turn the fastening nut (only
applies for screw fastenings
with adjusting threads) half a turn in order to pre-tension the rubber buffer. Greater pre-tension is
not permissible. Secure the screw fastening from coming loose, e.g. with Loctite 242 or a second
nut.
