The following table shows the general failure causes and troubleshooting methods for helical gear motors
| Fault | Possible Causes | Treatment Methods |
|---|---|---|
| Reducer overheating |
1.Overload 2.Insufficient/excessive lubricating oil |
1.Check load, adjust to rated value or replace with higher-power reducer 2.Use oil as specified |
| Abnormal stable operation noise |
1.Rotation/grinding noise (bearing damage) 2.Knocking noise (irregular meshing) |
1.Check lubricating oil 2.Contact user service department |
| Abnormal unstable operation noise | Oil contamination or insufficient oil volume | Replace oil or add oil to rated volume |
| Breather oil leakage |
1.Excessive oil volume 2.Incorrect breather installation |
1. Correct oil level 2.Install breather properly |
| Oil leakage | Seal damage | Contact user service department |
| Output shaft not rotating when motor runs | Reducer key connection damage | Send for repair |
