The possibility of the harmonic reducer entering impurities is inferred:
1. The assembly environment of the harmonic reducer is poor;
2. The burrs of the harmonic reducer fittings themselves, such as the impurities left over from processing are not cleaned up, and the fittings have small burrs such as mouths, screw holes, etc.;
3. Use an air gun to blow and flush the workpiece to make impurities splash to the assembly table, etc.; for this phenomenon, attention should be paid: first, use an air gun to clean the workpiece away from the assembly environment, and secondly, please do not disassemble the harmonic wave when it is not ready. reducer;

4. The oil is polluted, that is, the impurities enter the oil;
5. The assembler is brought in during the assembly process. When the related parts of the harmonic reducer are cleaned, the operator should wash his hands with detergent to remove the impurities adhering to the hands or wear rubber gloves to assemble;
6. Use a fan to cool down in summer.
7. Thread glue or plane glue etc. enter
The above points are checked one by one, and the reason for the entry of impurities in the harmonic reducer can soon be found.
The harmonic reducer is easy to wear and fail during use, resulting in a decrease in accuracy. The following are some tips that need to be paid attention to in the daily use of the harmonic reducer, which will help prolong the service life.
1. Under normal circumstances, for the harmonic reducer that has been continuously operated for a long time, according to the standard of working 5000 hours or replacing the new oil once a year, it should be out of use for a long time, and new lubricating grease should be replaced before restarting the operation. When changing the oil, the same oil as the original one should be added, and it should not be mixed with oils of different brands, but oils with the same trademark and different viscosities are allowed to be mixed.
2. When replacing the lubricating grease, it should be replaced when the harmonic reducer has cooled down without the danger of burning but is still warm under the condition of power failure, because when the oil temperature is completely cooled, the viscosity of the oil will increase, and it will become difficult to drain the oil. .
3. When it is found that the temperature rise exceeds 80℃ and abnormal noise occurs during operation, the operation should be stopped, the cause should be found out and the fault will be eliminated, and the operation can be continued after replacing the lubricating grease.
