Defective reason | analysis | Solution method | |
Noise | Knocking | Gear surface damaged | Contact manufacturer,replace gear set |
Continual cacophony | Bearing damaged | Replace the damaged bearing | |
Periodical cacophony | Particle on gear surface | Check gear surface | |
Neigh | Lack of lubricant | Fill with lubricant | |
Intermittent cacophony | Dirty lubricant | Replace the new lubricant | |
Shake | Fixed foundation shake | Deflective mount on the surface | Re-adjust fixed pedestal |
Output shaft shake | Bearing damage | Replace the damaged bearing | |
Inner gear parts shake | Gear damage | Replace the damaged gear | |
Housing shake | Defective gear assembly | Re-adjust the gear set | |
Leakage | Oil seal leakage | Oil seal vulcanize | Replace the damaged oil seal |
Housing leakage | Housing with the sand hole | Replace housing with the sand hole | |
Housing shake | O-ring damaged | Replace the damaged O-ring | |
Over-heating | Oil seal damaged | Over-tighten oil seal | Replace over-tighten oil seal |
Over-heat housing | Over-road | Re-calculate load | |
Lack of lubricant | Low lubricant | Fill with lubricant | |
Over-heat motor | 1,the temperature of environment is too high 2,airiness is bad 3,pressure is too high or too low | 1,take measure to reduce the temperature 2,clean out the wind passage and check the motor if cooling fan has been damaged 3,adjust electrical source pressure | |
The motor can`t work | Electrical source haven`t been switched on | Check if the switch is contacted will,if the fuse wise is broken or the motor down-lead is broken | |
The rotate speed of the output shaft is too low | Wrong control connection outside Over loading Wrong ratio Electrical source pressure too low Over-load | Correct is on the right connection Reduce the load Check the rotation ratio of the cooling fan and output shaft by hand Adjust electrical source pressure Reduce load | |
Motor circumrotate,output shaft don`t circu mrotate | Inner gear set damaged | Please contact the manufacture to replace the gear set |
