Timing Belt And Pulley Operational Reasons And Solutions (3)

Timing Belt And Pulley Operational Reasons And Solutions (3)

Belt contractions

Reasons: Mix other things or sharp residue

Treatments: Improve the environment, increase shield

Noise while running

Reasons:

1. Belt tension be too serious

2. Tow-axis parallel are misalignment

3. Belt width is greater than the belt pulley diameter

4. Under heavy load

5. Belt and pulley grip badly

Treatments:

1. Reduce tension

2. Adjust pulley orientation

3. Check the design

4. Check the belt and pulley

   
   

Belt pulley fray

Reasons:

1. Under heavy load

2. Belt tension be too serious

3. Belt pulley material is poor

4. Mix fray dust

Treatments:

1. Check the design

2. Reduce tension

3. Use high hardness material and take hardening treatment

4. Improve the environment, increase shield

   
   

Looks like stretched

Reasons:

1. Short distance between principal axis

2. Use weakly pulley material

Treatments:

1. Adjust the distance principal axis, reinforce bearing support

2. Use high hardness material pulley and take hardening treatment
