6.3 V-BELTS
Qube incorporates an innovative, automatic V-belt tensioning system combining motor mass and spring
tension to maintain a constant and appropriate force on the V-belts, lengthening belt life. (See Figure 6)
Additionally, the automatic V-belt tension system provides for even tension on the belts throughout the
operating life of the belts, reducing wear on the belts, shafts and bearings. A visual inspection of the V-belt
drive should yield the appearance shown in Figure 7.
The Qube also has a visual
indicator for the belt tension
and is set at the factory;
however, this setting may
have changed in transit,
necessitating adjustment.
When the belt is properly
tensioned the visual indicator
(pin) is at the top position. As
the belts stretch the indicator
moves downward. When the
pin reaches the lower most
position the belt tension
should be readjusted such
that the indicator is again in
the bottom position.
It is recommended to check
belt tension monthly and make
any manual adjustments
found necessary:
1. Turn off and lock out
power to your Qube.
2. Turn top latches and
open top panel of the
enclosure.
3. Remove front door by
removing (2) bolts and
lifting door.
4. If visual indicator pin has
not reached the bottom of
the indicator slot, then the
belt(s) is (are) properly
tensioned and no
adjustments are required.
If the visual indicator pin
has reached the top of
the indicator slot then
the belt(s) needs to be
re-tensioned by following
the remaining steps.
