The noise of the reducer is mainly caused by the friction, vibration and collision of the transmission gear. How to effectively reduce and reduce the noise and make it more in line with environmental protection requirements is also a key research topic at home and abroad. Reducing the gear transmission noise during the operation of the reducer has become an important research topic in the industry. Many scholars at home and abroad regard the change of gear tooth stiffness in gear transmission as the main factor of gear dynamic load, vibration and noise. Use the shape modification method to minimize the dynamic load and speed fluctuations to achieve the purpose of reducing noise. This method has proved to be a more effective method in practice. However, with this method, there is a need for a trimming device in the process, and large and medium-sized factories are often unable to implement it.

Reducer application field
After years of research, it is proposed to optimize the gear parameters, such as the displacement coefficient, the tooth height coefficient, the pressure angle and the center distance, to minimize the impact velocity, and the ratio of the impact velocity to the impact velocity is at a certain value. The range, the gear design method that reduces or avoids the impact of the pitch circle, can also significantly reduce the gear noise of the reducer. For the noise problem of the gearbox, it is also possible to use the METTLER Super Sealant or Lubricant, which is an excellent gearbox additive that forms a film of inert material on the part, reducing friction, gear noise and leakage.
