Improper belt tension and misalignment develop
bearing and belt failures.
FIGURES 1 and 2 deal with proper tension and
correct alignment of belts and pulleys when used
on blower applications.
FIGURE 1 indicates the recommended tension,
determined by grasping the belt as shown and
when a normal pressure is applied, a deflection of
approximately 1” in the belt will occur.
If the deflection is much in excess of that indi-
cated, belt slippage may occur and excessive belt
wear can result.
If the deflection is somewhat less than indicated,
the belt is too tight and will shorten the life of the
bearing. Excessive tension will actually pull the
shaft through the oil film in the bearing and
allow metal to metal contact. In addition to
decreasing the bearing life, it will contribute to
noisy blower operation. Any defects in the belt or
pulleys will be exaggerated.
FIGURE 2 deals with a recommended method for
checking correct alignment of pulleys. Excessive
misalignment produces increased belt wear and
can produce lateral motion of the wheel and shaft
to the point that considerable noise can develop.
