Solution:
1、Calibrate the positioning of the pulley.
2、Increase the rigidity of the bearing and fix it firmly.
3、Correct the retaining edge or replace it.
4. Check the design.
Point 3.Synchronous belt tooth surface wear

2、Adjust the belt tensioning force.
3、Improve the environment and increase the protective cover.
4、Repair the light wheel teeth or change the pulley.
Point 4. Synchronous belt teeth break off
1、Skipped teeth.
2. Passive mechanical accident load increases.
Solution:
1. Check the design.
2、Adjust the proper tensioning force.
3、Increase the diameter of the pulley and increase the number of teeth.
4、Exclude passive mechanical failure
Point 5. Synchronous belt with rubber backing wear and cracking
1、The external tensioning wheel rotation is blocked.
2、Outer tensioning wheel misalignment.
3. Encounter the frame of the machinery.
4、Long-term low temperature state.

2、Check and adjust the tensioning wheel.
3、Do not stick to oil or change the oil-resistant synchronous belt.
Point 7. Belt longitudinal cracking
1、The timing belt runs beyond the edge of the pulley.
2、Synchronous belt rolls up the retaining edge of the pulley.
Solution:
1、Adjust the position of the belt pulley.
2、Enhance the bearing rigidity and fix firmly.
Point 8. The fracture of the tensile body part
1、Incorrect loading and unloading of timing belt.
2, mixed with debris or sharp and sharp residues.
Solution:
1、The correct method of loading and unloading synchronous belt.
2、Improve the environment. Add protective cover.
Point 9. Too much noise when running
1、Tensioning force of synchronous belt is too large.
2. Parallel misalignment of the two axes.
3、The width of the timing belt is larger than the diameter of the pulley.
4、The load is too large.
