Synchronized zone faults

1. Overload;

Check the design; Choose the correct bandwidth;

2. The inertia of driven wheel is too large.

Choose the correct synchronous pulley;

3. The diameter of synchronous pulley is too small.

Redesign the number of meshing teeth;

4. Excessive pretension force;

Adjust appropriate preload;

5. Torsion of synchronous belt, poor operation;

Careful operation of storage, transportation and installation;

6. Excessive impact load

Prevent accidental failure and change design

7. The synchronous belt climbs up the retaining ring.

Adjust the axis parallelism and check the retaining ring.

8. Fragments or foreign objects fall into the transmission.

Clean up dirt and check protective baffles.

Overwear of synchronous belt edge

1. Synchronized pulleys are not parallel;

Adjust parallelism;

2. Insufficient stiffness of bearing parts;

Increase stiffness, it is fixed.

3. Bending of retaining ring;

Correction or replacement of retaining ring;

4. Rough surface of retaining ring;

Correction or replacement of retaining ring;

5. The synchronous belt touches the protective baffle or bracket of the transmission device.

Check the protective baffle or bracket.

Overwear of synchronous belt teeth

1. Overload;

Check the design and choose the correct bandwidth.

2. The pre-tightening force is too large;

Adjust appropriate preload;

3. Rough surface of gear teeth;

Check and adjust the surface roughness.

4. Serious radial runout of synchronous pulley;

Check and adjust radial circular runout;

5. Dust or sand;

Avoid mixing in sundries.

6. Vigorous vibration;

Adjustment of structure or use of shock absorber;

7. Too much dirt falls into the transmission.

Clean up dirt.

Cutting with teeth

1. Overload or excessive impact load;

Check design;

2. The number of meshing teeth is not less than 6 teeth or belt.

Check the design to make the number of teeth odd;

The number of teeth is a multiple of the number of teeth.

3. The pretightening force is too small.

Adjust preload;

4. The diameter of synchronous pulley is too small.

5. Excessive ambient temperature or mixing of oil and other impurities

Change the ambient temperature and use protective cover.

6. The load suddenly increases when the accident stops running.

Check equipment to prevent cattle accidents again.

Longitudinal fissure of synchronous belt

1. The synchronous belt runs out of the synchronous pulley;

Adjust parallelism;

2. The synchronous belt runs to the retaining ring.

Adjust the parallelism and check the retaining ring.

3. The synchronous belt is cut on the retaining ring during installation.

Pay attention to installation.

Synchronization belt elongation

1. The bearing is not fixed reliably, and the center distance decreases during operation.

Attention should be paid to the improvement of the structure during installation or design.

2. Looseness of tension layer;

Replacement belt;

3. Tension wheel loosening;

Check the tension wheel, pay attention to installation;

4. Synchronized pulley wear;

Replacement of synchronous pulley;

5. Overload.

Check the design and change the bandwidth.

With back crack or band softening

1. The ambient temperature is too high.

Change the ambient temperature.

Excessive noise in operation

1. Overload;

Check design;

2. The pre-tightening force is too large;

Adjust preload;

3. Synchronized pulleys are not parallel.

Adjust parallelism and calibrate during installation.

4. The diameter of synchronous pulley is smaller than the bandwidth.

Check design;

5. Bad meshing between synchronous belt and synchronous pulley.

Check the synchronous belt and pulley.
