Reducing machine noise processing method

Gear transmission schematic The noise generation of the Cycloidal reducers is mainly due to the friction, vibration and collision of the transmission gear, how to effectively reduce and reduce the noise, make it more environmentally friendly requirements is also a key research topic at home and abroad.
Reducing the gear transmission noise of the parallel shaft helical gearbox has become an important research topic in the industry. Many scholars at home and abroad regard the change of the meshing stiffness of the gear in the gear transmission as the main factor of the dynamic load, vibration and noise of the gear. With the modified method, so that the dynamic load and speed fluctuations to a minimum, in order to achieve the purpose of reducing noise. This method proved to be a more effective method in practice. But with this method, the process needs to have modified equipment, the majority of small factories are often unable to implement.
After years of research, it is proposed that by optimizing the gear parameters such as the displacement coefficient, the tooth height coefficient, the pressure angle and the center distance, the meshing impact velocity is reduced to a minimum, and the ratio of the outburst impact velocity to the hitting impact velocity is at a certain value Range, to reduce or avoid the impact of the pitch circle gear design method, but also significantly reduce the gear unit gear noise.
