Step 5: Examine for Tough or Worn Surfaces
Run your fingers alongside the floor of the pulleys to detect any roughness or unevenness. Worn or tough surfaces can enhance friction between the belt and pulley, inflicting untimely put on and overheating.
Step 6: Examine the Pulley Bearings
If potential, verify the pulley bearings for any play or looseness. Defective bearings could cause the pulleys to wobble or misalign, which might adversely have an effect on the belt’s efficiency.
Step 7: Examine the Pulley Hub
Study the pulley hub for any cracks, bends, or deformations. A compromised hub can weaken the pulley and enhance the danger of catastrophic failure.
Step 8: Examine Pulley Offset and Runout
Utilizing a dial indicator, measure the offset and runout of every pulley. Offset refers back to the lateral displacement of the pulley from the middle of the shaft, whereas runout measures the variation within the pulley’s rotation.
| Acceptable Offset | Acceptable Runout |
|---|---|
| Lower than 0.020 inches | Lower than 0.005 inches |
Extreme offset or runout could cause the belt to vibrate or slip, resulting in decreased efficiency and decreased lifespan.
