Synchronous belt common problem summary and solution

- Jul 11, 2019-

First, the early break of the synchronous belt

1. The inertial forces of the passive wheel and the passive load are not taken into account.

2. The load is too large or the passive wheel is stopped due to an accident, which greatly increases the load force.

3. The pulley is too small and the belt is forcibly bent.


1. Improve the design.

Timing belt improved design

2. Check the design and replace it with a pulley with more than the original minimum number of teeth.

3. Pay attention and be careful when handling, storage and installation.

Second, the timing belt wear

1. The parallelism of the wheel is not allowed.

2. The bearing rigidity is insufficient.

3, with the wheel rib bending.

the timing belt wear

4. The diameter of the pulley is smaller than the belt width.


1. Correct the positioning of the pulley.

2. Increase the rigidity of the bearing and fix it firmly.

3. Correct the ribs or replace them.

4. Check the design.

Timing band correction

Third, synchronous toothed surface wear

1. The load is too large.

2. The belt tension is too large.

3, mixed with a layer of abrasive powder.

4, the teeth are rough.


synchronous toothed surface wear

1. Improve the design.

2. Adjust the belt tension.

3. Improve the environment and increase the protective cover.

4. Repair the gear teeth or change the pulley.

Fourth, synchronous toothed off

1. Jumping teeth.


2. The load of passive mechanical accidents increases.


1. Check the design.

2. Adjust the appropriate tension.

3. Increase the diameter of the pulley and increase the number of teeth.

4. Eliminate passive mechanical failure

5. Synchronous belt with adhesive wear and cracking

1. The outer tensioning wheel is blocked.

2. The outer tensioning wheel is not positioned properly.

3. I encountered a mechanical frame.

4, long-term low temperature.


High speed drive belt

1. Repair or replace the tensioner bearing.

2. Correct the position of the tensioning wheel.

3. Check and correct the mechanical parts.

4. Improve the ambient temperature.

Sixth, with adhesive rubber softening:

1, high temperature

2. The tensioning wheel stops.

3. Stick to oil.


1. Improve the ambient temperature.

2. Check and adjust the tensioning wheel.

3, do not stick oil or change the oil resistant timing belt

Seven, the belt longitudinal crack

1. The timing belt runs beyond the edge of the pulley.

2. The timing belt is wound with a rim on the pulley.


1. Adjust the position of the pulley.

2, enhance bearing rigidity, and securely fixed

Eight, the tensile part of the tensile part

1. Improper loading and unloading of the timing belt.

2. Incorporate debris or sharp and sharp residue.


1. Correctly load and unload the timing belt method.

2. Improve the environment. Add a protective cover.

Nine, the noise is too large during operation

1. The timing belt tension is too large.

2. Parallel misalignment of the two axes.

3. The width of the timing belt is greater than the diameter of the pulley.

4. The load is too large.

5. The timing belt and the belt teeth are not well connected.

1. Reduce the tensioning wheel (no deviation of the teeth).

2. Adjust the positioning of the pulley.

3. Improve the design.

4. Improve the design.

5. Check the timing belt and pulley.

Ten, with tooth wear

1. The load is too large.

2. The tension of the timing belt is too large.

3. The material of the pulley is not good.

4. Incorporating abrasive dust.

1. Improve the design.

2. Reduce the tension.

3. Use a material with high hardness and harden the surface.

4. Improve the environment and increase the protective cover.
