How To Reduce The Impact Of Planetary Reducer Noise?

The impact of gear processing on the noise of the reducer in the planetary reducer. The noise has a great influence on the stability of the work accuracy, the contact accuracy of the gear, the movement accuracy of the gear, the assembly accuracy and so on. If you want to reduce the noise of the reducer, To know the cause of the noise, the noise of the speed gear is caused by the vibration caused by the periodic alternating force generated by the internal gear meshing on the bearing and the box during its operation. The main criterion for evaluating the quality level of a cylindrical gear reducer (referred to as the reducer above) is its noise value.

After years of research, it is proposed to optimize gear parameters, such as modification coefficient, tooth height coefficient, pressure angle, center distance, to minimize the impact velocity of engagement, and the ratio of impact velocity of engagement to a certain value. Range, reduce or avoid the gear design method of meshing pitch circle impact, can also significantly reduce gear noise.

Reducing the gear transmission noise during operation of planetary reducers has become an important research topic in the industry. Many scholars at home and abroad regard the change of gear tooth meshing stiffness in gear transmission as the main factor of gear dynamic load, vibration and noise. Use the method of shape modification to minimize the dynamic load and speed fluctuation to achieve the purpose of reducing noise. This method has proved to be a more effective method in practice. However, with this method, the process requires shaping equipment, which is often impossible for the majority of small and medium factories.

The above discusses several common methods to reduce the noise of gear reducers, such as methods to reduce gear installation errors, methods to improve gear lubrication, and methods to improve improper matching of the box body and internal parts, and so on.
