Common Faults and Solutions for V Belts
A: There is noise: the tension is too large or too small, the solution: the tension should be adjusted.
B: Edge wear:
1) Timing belt incident is not parallel
2) Timing belt wheel steering deflection
3) Rising pulley has cracks
4) Bearing has gaps
Solution:
1) Straighten the non-parallel synchronous belt wheels and replace the synchronous belt.
2) Replace the tensioner, suspension wheel and timing belt
C: Wear of the surface fabric at the root of the convex tooth
(1) Excessive tension
(2) Excessive temperature
(3) Damage to the synchronous pulley.
Solution:
(1) Adjust the tension
(2) Find the cause of the high temperature and repair it
(3) Replace the synchronous pulley
D: The flanks of the convex teeth are abnormally worn, the bottom is cracked, and the convex teeth are cut:
(1) The tightening force is too large or too small
(2) There is foreign body
(3) The timing belt pulley or the tension pulley is seized.
Solution:
(1) Adjust the tension
(2) Remove foreign objects
(3) Find the cause and repair
E: The volume of the surface fabric of the convex teeth: the engine or other parts have liquid leakage.
Solution: repair the leaking parts and replace the timing belt
F: Movement scratches on the convex teeth:
(1) Foreign matter
(2) The timing belt is damaged before or during installation
Solution:
(1) Remove foreign objects
(2) Replace the timing belt and install it correctly
G: Cracks appear on the back of the synchronous belt:
(1) The surrounding temperature is too high or too low
(2) There is foreign matter
(3) The suspension wheel is sticky
(4) Aging
Solution:
(1) Find the cause and solve it
(2) Replace the timing belt and check the door cover
(3) Replace the idler wheel and timing belt
(4) Replace the timing belt
H: The timing belt suddenly breaks:
(1) There is a foreign body
(2) The tension is too large
(3) The timing belt is improperly bent before installation
Solution:
(1) Remove foreign matter
(2) Adjust the tension
(3) Replace the timing belt
I: Related parts are damaged:
(1) There is a gap in the bearing
(2) The moving contact surface is damaged
Solution: (1) Replace the tensioner, idler and guide wheel
