CONVEYING BELT TENSION AND ALIGNMENT
A contoured belt with molded flights is used to convey material along the frame. The
tension and alignment of the belt should be checked weekly, or more often if required,
to be sure that it does not slip or run to one side. A properly tensioned belt will not slip
when it is operating. Operating the belt with less slippage will increase the belt life and
causes less stress on bearings, pulleys and shafts.
To maintain the belt, follow this procedure:
Place all controls in neutral or off, stop motor and disable power
source before working on belt.
1. Use the take-up bolts located at the tail to set the tension of the belting.
2. If the belt needs to be tightened to prevent slippage, use the take-up adjustments
on the tail end only.
3. The belt is tightened by turning both take-up adjustments an equal number of
turns.
4. Use the drive roller to check the alignment. The belt should be centered.
5. Turn the belt 1/2 revolution when the belt is new and check the drive and tail roller.
If out of alignment, the belt will move to the loose side. Loosen the jam nut on the
bearing position bolts and adjust those bolts to set the position of the belt. Once the
alignment is set, tighten the jam nuts.
6. Run and check again. Check frequently during the first few minutes of operation
and then several times during the first 10 hours. The belt normally seats itself
during the first 10 hours of operation and can be checked weekly after that.
7. The belt is properly aligned when the belt runs in the center of the head and tail
rollers.
