Troubleshooting Troubleshooting ?Synchronous belt/Belt sprocket
1 |
---|
Cause 1 | Overload | Solution | Check the inertia of the driven object, motor, conditions of use, etc. |
---|---|---|---|
Cause 2 | Shock load | Solution | Increase the belt size or install a shock damping mechanism. |
Cause 3 | Bent belt | Solution | Exercise caution during belt transportation, storage and installation. |
Cause 4 | Too small belt sprocket diameter | Solution | Increase the number of belt sprocket teeth above the allowable minimum number of teeth. |
2 |
---|
Cause 1 | Overload | Solution | Modify the design. |
---|---|---|---|
Cause 2 | Too high installation tension | Solution | Adjust the installation tension. |
Cause 3 | Insufficient installation tension | Solution | Adjust the installation tension. |
Cause 4 | Incorrect belt sprocket tooth profile or incorrect dimensions of the tooth part | Solution | Use a belt sprocket having the correct tooth profile and dimensions. |
Cause 5 | Use in dusty atmosphere | Solution | Improve the atmosphere or install a cover. |
3 | Belt tooth jumping |
---|
Cause 1 | Shock load | Solution | Increase the belt size. |
---|---|---|---|
Cause 2 | Insufficient belt installation tension | Solution | Apply an adequate installation tension. |
Cause 3 | Insufficient number of meshed teeth | Solution | Either increase the number of belt sprocket teeth or increase the number of meshed teeth by using an idler. |
Cause 4 | Insufficient rigidity of frame on which belt is used | Solution | Use a frame having sufficient rigidity. |
4 |
---|
Cause 1 | Ultimate symptom of Problems 2 and 3 | Solution | Same action as for Problems 2 and 3. |
---|
5 |
---|
Cause 1 | Poor parallelism between shafts | Solution | Make the shafts parallel. |
---|---|---|---|
Cause 2 | Poor belt sprocket alignment | Solution | Align the belt sprockets accurately. |
Cause 3 | Insufficient rigidity of frame on which belt is used | Solution | Use a frame having sufficient rigidity. |
Cause 4 | Bent flange | Solution | Replace the bent flange with a good one or remedy the bent flange. |
6 |
---|
Cause 1 | Belt running on edges of belt sprocket | Solution | Align the belt sprockets and make the shafts parallel. |
---|---|---|---|
Cause 2 | Belt running on flange | Solution | Apply an adequate installation tension. |
7 |
---|
Cause 1 | Jammed with foreign objects | Solution | Improve environment or install a cover. |
---|---|---|---|
Cause 2 | Belt running on flange | Solution | Apply an adequate belt installation tension and make the shafts parallel accurately. |
8 |
---|
Cause 1 | Swelling due to oil/water | Solution | Either improve environment so that the belt is not wetted by oil/water or install a cover. |
---|
9 | Apparent elongation of belt |
---|
Cause 1 | Approaching shafts due to movement of shafts | Solution | Secure the bearing rigidly. If shock is strong, use a stopper to prevent the bearing from moving. |
---|
10 |
---|
Cause 1 | Slipping of back pushing idler | Solution | Apply an adequate installation tension. Reduce the inertia of the idler |
---|---|---|---|
Cause 2 | Adhesion of oil | Solution | Either improve environment so that the belt is not wetted by oil or install a cover. |
Cause 3 | Use in high temperature atmosphere | Solution | Lower the atmosphere temperature |
11 | Wear of rubber on back of belt |
---|
Cause 1 | Poor parallelism of back pushing idler shaft | Solution | Make the idler shaft parallel. |
---|---|---|---|
Cause 2 | Poor rotation of back pushing idler | Solution | Improve idler rotation. |
12 |
---|
Cause 1 | Too small belt sprocket diameter | Solution | Increase the belt sprocket diameter. |
---|---|---|---|
Cause 2 | Use in low temperature atmosphere | Solution | Optimize atmosphere temperature |
13 |
---|
Cause 1 | Inadequate belt sprocket material | Solution | Impart wear resistance to the belt sprocket by using harder material, hardening the tooth surface or surface treatment. |
---|---|---|---|
Cause 2 | Use in dusty atmosphere | Solution | Improve the atmosphere or install a cover. |
Cause 3 | Too high installation tension | Solution | Adjust the installation tension. |
14 | Noise |
---|
Cause 1 | Too high installation tension | Solution | Apply an adequate installation tension. |
---|---|---|---|
Cause 2 | Overload | Solution | Increase the belt size. |
Cause 3 | Poor shaft parallelism or poor belt sprocket alignment | Solution | Make the shafts parallel and align the belt sprockets. |
