The harmonic reducer realizes the harmonic transmission function through elastic deformation. Compared with other gear reducers, its noise is relatively small, and the main reason for the noise is caused by the friction, vibration and collision of the gear transmission. How to do it? To effectively reduce noise, what problems should be paid attention to in use, this article will introduce the use and maintenance of the reducer.

Timely and reasonable use of lubricating oil: wrong use of lubricating grease, unreasonable lubrication and wrong use of lubricating grease will cause immeasurable damage to the reducer. When rotating at high speed, the friction of the gear tooth surface will generate a large amount of star heat energy. Improper lubrication will cause damage to the tooth surface, affect the accuracy of the precision, and increase the noise. In the design, proper calculations must be made between gear pairs to compensate for thermal deformation and to store oil. Reasonable use and selection of lubricating oil can ensure the safe and effective operation of the system, delay the deterioration trend of the system, and stabilize the noise level.

Correct use of harmonic reducer: normal use according to the load range specified by the manufacturer can avoid damage and damage to components and ensure the stability of the noise level. Wrong use of harmonic reducer: the noise of harmonic reducer will increase with the increase of load. If it is increased, the use of illegal oversized loads will increase its noise and greatly reduce its service life.

Regular maintenance: Regularly replace the grease of the harmonic reducer, replace the worn parts, tighten the loose parts, remove the internal impurities, realize the functions of cleaning the gearbox, quickly filter the waste oil, etc., which can ensure the safe operation of the harmonic reducer and reduce the noise and prolong the service life.
