The harmonic reducer realizes the harmonic transmission function through elastic deformation. Compared with other gear reducers, its noise is relatively small. The main reason for the noise of the harmonic reducer is the friction, vibration and collision of the transmission gear. What are the causes and solutions for the noise of our harmonic reducer during use?
1. Cause one of the noise of the harmonic reducer:
Product accuracy problem: The accuracy of the harmonic reducer is not up to the standard, which will cause the friction, vibration and collision of the transmission gear to become more intense, resulting in greater noise, and in severe cases, it will damage the harmonic reducer.
Solution: Strictly control the accuracy of the harmonic reducer during production.

2. The second reason for the noise of the harmonic reducer:
Wrong use of lubricating grease: Unreasonable lubrication and wrong use of lubricating grease will cause immeasurable damage to the reducer. At high speeds, gear tooth surface friction will generate a lot of heat, improper lubrication will cause damage to the gear teeth, affect accuracy, and increase noise. The design requires the gear pair to have an appropriate clearance (the clearance between the non-working surfaces of the meshing gear teeth to compensate for thermal deformation and store lubricating grease).
Solution: The correct selection and use of special grease for harmonic reducers can ensure the safe and effective operation of the system, delay the deterioration trend, and stabilize the noise level.
3. Three reasons for the noise of the harmonic reducer:
Wrong use of harmonic reducer: the noise of the harmonic reducer will increase with the increase of the load, and the use of harmonic reducer in violation of the regulations for over-large loads will increase its noise and greatly reduce its service life.
Solution: Normal use according to the load range specified by the manufacturer.
4. Four reasons for the noise of the harmonic reducer:
There is no regular maintenance and maintenance: regular replacement of grease, replacement of worn parts, loose parts of fasteners, removal of internal debris, can effectively reduce noise.
Solution: Regular maintenance and maintenance can ensure the safe operation of the harmonic reducer, reduce noise, and extend the service life.
There are four main reasons for the noise of the harmonic reducer. These illegal production and use of the harmonic reducer should be avoided and eliminated as much as possible, so that the noise problem of the harmonic reducer can be solved more effectively, and it can be more effective. In order to prolong the service life of the harmonic reducer, the safety of the harmonic reducer can be more effectively guaranteed.
