How to deal with reduction motor noise?

The noise generated by the reduction motor mainly comes from the friction, vibration and collision of the transmission gear. How to effectively reduce and reduce noise to make it more in line with the requirements of environmental protection is also a key research topic at home and abroad.

Reducing the gear transmission noise during the operation of the reduction motor 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 shape modification methods to minimize dynamic loads and speed fluctuations to achieve the purpose of reducing noise. Practice has proved that this method is an effective method. However, using this method requires shaping equipment, which is often unavailable in most small and medium-sized factories.

After years of research, it is proposed to optimize gear parameters, such as displacement coefficient, tooth height coefficient, pressure angle, and center distance, so as to minimize the meshing impact speed and the ratio of the meshing impact speed to the meshing impact speed to be within a certain numerical range. Gear design methods that reduce or avoid meshing pitch circle impact can also significantly reduce reduction motor gear noise.
