2.4 Installation

2.4.1 Preparation
Clean the gearbox shaft using a cloth soaked in white spirit, alcohol, or acetone, making
sure that the solvent does not get under the lip seal.
The geared motor must be in a horizontal position for cleaning.
Geared motor assembly :
The operation life of geared motor bearings depends largely on the care and attention
given to this operation.

The following formula is generally used as a good means for ascertaining the pulley radial
load :
M
= ×
Fr K 10
R
Belt tension must never exceed the values given by the manufacturer.
This tension can be determined with an instrument that measures natural belt flexion
frequency.
We cannot be held responsible for the gear box shaft fatigue resulting from excessive
strain.
The permissible loads (axial et radial) on the shaft are given as guidelines for a given shaft
diameter.
• Check that the gear shaft is carefully lined up with the
driven machine shaft so as to prevent vibrations, uneven
rotation or excessive stress forces on the shaft.
• Do not bang the shaft and avoid pressing fitting which
could score the bearing races (diagram 1).
• Use the threaded shaft end for fitting pulleys or
accessories. Parts may be brought into contact with the
nut or the shaft collar located under the lip seal (diagram
2).
• Where toothed drive belts are used the drive pulley must
be fastened as close as possible to the flange. The pulley
diameter is to be chosen so that the radial force does not
exceed the limits shown on the graphs on the following
pages.
Fr = radial loadl (N)
M = maximum output torque (N.m)

R = pulley radius (mm)
K =1,5 with a cogged belt
K = 2,5 with a V belt
K = 3,5 with a flat belt
