Ten common problems and solutions for synchronous belts
2025-10
1. Early fracture of the synchronous belt;
1. The inertia force of the passive wheel and passive load is not considered.
2. The load is too large or the passive wheel stops rotating due to an accident. Thereby greatly increasing the load force.
3. The pulley is too small. The belt was forcibly bent.
Solution 1. Improve the design. 2. Check the design and replace it with a pulley with a smaller number of teeth than the original one. 3. Full attention and caution should be exercised during handling, storage, and installation operations.
2. Belt edge wear of synchronous belt:
1. The parallelism of the wheels is not accurate.
2. Insufficient bearing rigidity.
3. The pulley ribs are bent.
4. The diameter of the pulley is smaller than the width of the belt.
Solution: 1. Correct the positioning of the pulley. 2. Increase the rigidity of the bearing and fix it firmly. 3. Correct or replace the ribs. 4. Check the design.
3. Tooth surface wear of synchronous belt:
1. The load is too large.
2. The belt tension is too large.
3. Mixed with abrasive powder layer. 4. Rough gear teeth.
Solution: 1. Improve the design. 2. Adjust the belt tension. 3. Improve the environment and increase the protective cover. 4. Polish the gear teeth or replace the pulley.
Four, the tooth of the synchronous belt breaks down:
1. Jumping teeth.
2. Passive mechanical accident load increases.
Solution: 1. Check the design. 2. Adjust the appropriate tension. 3. Increase the diameter of the pulley. Increase the number of teeth. 4. Eliminate passive mechanical failures.
5. Wear and cracks of the rubber backing of the timing belt:
1. The rotation of the outer tension wheel is blocked.
2. The positioning of the outer tension wheel is misaligned.
3. It hits the frame of the machine. 4. Long-term low temperature state.
Solution: 1. Repair or replace the tensioner bearing. 2. Correct the position of the tension wheel. 3. Check and correct the mechanical parts. 4. Improve the ambient temperature.
6. Softening with adhesive:
1. High temperature
2. The tensioner stops rotating.
3. Stick oil.
Solution; 1. Improve the ambient temperature. 2. Check and adjust the tension wheel. 3. Do not stick to oil or change the oil-resistant timing belt
Seven, the belt is longitudinally cracked;
1. The timing belt runs beyond the edge of the pulley.
2. The timing belt is rolled on the side wall of the pulley.
Solution: 1. Adjust the position of the pulley. 2. Enhance the rigidity of the bearing and fix it firmly.
8. Fracture of the tensile body part;
1. Incorrect loading and unloading of the timing belt.
2. Mixed with debris or sharp residue.
Solution; 1. Correctly load and unload the timing belt. 2. Improve the environment. Increase the protective cover.
9. Excessive noise during operation:
1. The tension of the timing belt is too large.
2. The 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 toothing of the timing belt and the pulley is not good.
Solution; 1. Reduce the tensioner wheel (no skipping of teeth shall prevail). 2. Adjust the positioning of the pulley. 3. Improve the design. 4. Improve the design. 5. Check the timing belt and pulley.
10. Wear of belt gear teeth;
1. The load is too large.
2. The tension of the synchronous belt is too large.
3. The material of the pulley is not good.
4. Incorporate abrasive dust.
Solution; 1. Improve the design. 2. Reduce the tension. 3. Use high-hardness materials and harden the surface. 4. Improve the environment and increase the protective cover.
