Reducer noise processing Posted by : admin / Posted on : Jun 19， 2020

The noise generated by the reducer is mainly due to the friction, vibration and collision of the transmission gear. How to effectively reduce and reduce the noise to 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 in the meshing stiffness of the gear teeth in the gear transmission as the main factors of gear dynamic load, vibration and noise. Use the shape modification method to minimize the dynamic load and speed fluctuation to achieve the purpose of reducing noise. This method proved to be a more effective method in practice. However, with this method, the shape-repairing equipment is required in the process, and it is often impossible for large and medium-sized factories to implement it.
After years of research, it has been 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 of the engagement, and the ratio of the impact velocity of the engagement to the impact velocity of the engagement is at a certain value The scope of the gear design method to reduce or avoid the impact of meshing pitch circles can also significantly reduce the gear noise of the reducer. For the noise problem of the reducer, you can also use Maitre Super Sealant or Lubricant, which is an excellent gearbox additive that can form a film of inert material on the components to reduce friction, gear noise and leakage.
