V-belts
are used on older model heavy spinner hangers. The proper installation
procedures, alignment, inspection and general maintenance of these drives are vitally
impo11ant to efficient performance of the machine.
Always use matched belts. V-belts are manufactured either by molding or are cut
to specified shape. The cross-sectional dimensions of v-belts made by various
manufacturers are not always identical, some belts may be slightly wider, some thinner or
the angle of the belt sides may be different. Make sure that all the belts on one drive are
from the same manufacturer and that they are properly matched. Never match used belts
with new ones. Belts which are improperly matched could cause a reduction in the
efficiency of the v-belt drive.
Always use matched sheaves. A sheave with an improper diameter for the belt
being used will cause a significant reduction in belt life.
When replacing v-belts it should not be necessary to pry or lever them into or out
of the sheave grooves. If excessive force is used to pry v-belt internal breakdown may
occur. To properly install or remove v-belts release pressure on the air cylinder or release
tension on the drive chain. This should allow the belt to be easily removed.
Always use a full set of v-belts. The efficiency and durability of a multiple v-belt
drive can only be assured if the drive is operated with a full set of belts as originally
designed. Operating a drive with less than a full set of v-belts results not only in loss of
efficiency but also causes an overload on the belts, shortening belt life.
Proper v-belt tension is important. If a drive is set up with the v-belts too tight, it
will force the belts to pull an unnecessary load which may cause overheating of the
bearings. If the drive is too loose, the belt may slip causing a drop in efficiency as well
as causing undue wear on the belts and sheaves. A v-belt drive is properly tightened
when a slight bow is noted on the slack side of the belt while it is running.
A void contact with oil, grease and acid. Oil and grease will cause swelling of the
v-belts and can result in premature failure. Do not be careless during lubrication. Acids
will greatly reduce belt life and hence all contact with acid should be avoided. Never use
belt dressing on a v-belt drive.
