5.4 Belt drive
Improper design and/or installation of the V-belt
drive can result in a considerable reduction of he
bearing life and/or to breakage of the drive shaft.
If the drive shaft breaks and/or in case of bearing
damage, ROTORCOMP can only grant a warranty
if the belt driven is properly designed and exe-
cuted.
The following information must be observed for
this purpose.
– The belt drive must not be underdimensioned.
The maximum design power for a belt drive is
contained in the technical data for the respec-
tive model.
– The belt pulley must be pushed onto the drive
shaft as far as possible and secured.
– Use a belt tensioner with a scale.
– Observe the belt tensioner and the tensioning
direction for the different belt types (V, flat,
toothed belt etc.).
– The V-belt pulleys must be balanced.
It is not permissible to drive the belt pulley onto
the drive shaft by striking it with a hammer, and
this can result in bearing damage.
– When aligning the belt drive, exact parallelism
without vertical and horizontal angular errors
must be ensured.
– A torsionally rigid base frame for the belt drive
must be installed so that it aligns exactly with
the compressor air end.
– "Fluttering" of the belt of the belt drive should
be prevented with construction measures (axis
spacing of pulleys, belt tension and stability of
the base frame and tensioner).
– Do not exceed the specified maximum power
P
max
at the drive shaft.
5.4.1 Belt tensioner with scale
Figure 5-3
The belt drive must first be correctly adjusted with
the pretension measuring device.
The tensioning element must be set to zero after
installation. This enables the correct belt tension
to be easily adjusted again without the pretension-
ing measuring device using the scale 1 on the ten-
sioning element.
