Inferring the possibility of entering impurities in the harmonic reducer: 1. The assembly environment of harmonic reducer is poor; 2. The burrs of the matching parts of the harmonic reducer, such as the impurities left under the impurities after processing, are not cleaned up, and the parts are stopped. Small burrs, etc;

Inferring the possibility of entering impurities in the harmonic reducer:
1. The assembly environment of harmonic reducer is poor;
2. The burrs of the matching parts of the harmonic reducer, such as the impurities left under the impurities after processing, are not cleaned up, and the parts are stopped. Small burrs, etc;
3. Use air guns and other processing parts to splash impurities on the assembly table. Pay attention to this phenomenon: first use the air gun to stay away from the assembly environment, and then please do not disassemble the harmonic reducer;
4. Oil is contaminated, that is, impurities into the oil;
5. The assembler enters the assembly process. When cleaning the relevant parts of the harmonic reducer, the operator should use detergent to wash his hands, remove impurities attached to his hands or wear rubber gloves;
6. Use a fan to cool down in summer.
7. Thread glue or flat glue, etc.
The above points one by one investigation, will soon be able to find the reason for the entry of impurities in the harmonic reducer.








The harmonic reducer is prone to wear and failure during use, resulting in reduced accuracy. The following are some tips that the harmonic reducer needs to be paid attention to in daily use to help extend the service life.
1. Generally speaking, for the harmonic reducer with a long continuous operation time, the standard is to replace the new oil for 5000 hours or once a year, stop the operation for a long time, and replace the new grease before starting the operation. When changing the oil, the same oil as the original factory should be added, and it should not be mixed with different brands of oil, but it is allowed to mix and use oil with the same trademark and different viscosity;
2. When replacing the grease, the harmonic reducer should be cooled when the power is off, and there is no risk of burning, but it should be replaced when it is still warm, because when the oil temperature is completely cooled, the oil viscosity increases and it is difficult to drain the oil.


3. During the operation, it is found that the temperature rise exceeds 80 degrees C. In addition to abnormal noise and other phenomena, it should also be stopped to find out the cause and eliminate the fault. After replacing the grease, it can continue to work;
