General Information
Maintenance of Belts
FIG. 30: Cross sections of some of the belts used on the
machine are shown.
A drive inspection must be done every one to two weeks.
Check belts frequently for excessive wear, tearing,
breaking, increasing, and unraveling.
Belt tensions are controlled with spring loaded idlers on
most drives on the machine. Over tightening puts too
much strain on the belt and too much loading on the
shafts and bearings.
Look and listen for any not normal vibration or sound
while watching the drive in operation. A drive kept in good
condition will operate smoothly with little noise.
Inspect the guards for looseness or damage. Keep all
guards free from debris, dust, or grime deposit on either
the inside or the outside of the guard. Deposits of material
on the guards operate as insulation causing the drives to
run hotter.
Belts that are running hot, running in a hot environment,
or from slipping will harden and form cracks from the
bottom of the belt up.
An internal temperature increase of 10 degrees C (18
degrees F) can cut belt life in half.
Inspect for oil or grease leaking on the drive. This can
indicate over lubricated bearings or a fluid leak. If this
material gets on the rubber belts, the belts can increase in
D-5594
size and become distorted, causing an early belt failure.
FIG. 30
Belts must be replaced if there are signs of cracking,
fraying, or not normal wear.
