3.3.2
Close design (with shaft sealing ring)
This variant incorporates an adapter plate (5) with
shaft seal (7), which means that the gearbox forms
a compact, closed unit.
The adapter plate (5) and drive hub (1) are
separately delivered loose. Clean the fitting
surfaces of the motor (3) and drive hub. Check
the motor shaft (2) for axial and radial runout as
described in chapter 3.1. Also lightly grease the
motor shaft.
After cleaning the fitting surfaces, place the
adapter plate with radial shaft seal (7) onto the
motor housing. Heat the drive hub to approx
120 °C from the opening and slide it onto the
motor shaft until it reaches the stop.
Then check reference dimension “C” and change
using shims if necessary.
CAUTION
Risk of motor shaft damage if the hub is not
sufficiently heated.
Tighten the threaded pin (9) and secure it to
prevent it from turning, see chap. 3.4.
CAUTION
Thoroughly grease the radial shaft seal and the
drive hub before installation. When installing,
make sure that the sealing lip and the radial
shaft seal are in the correct position.
NOTE
The radial shaft sealing ring in the drive motor
must be removed on the output end when the
closed design is used.
In the case of motor adaptation and loosely
supplied sealing/spacing washers, the latter must
be pasted in by means of a jointing compound
(e. g. Loctite 574) prior to assembly.
