Reducer of friction produces mainly stems from a drive gear noise, vibration and impact, how to effectively reduce and reduce noise, to make it more conform to the requirements of environmental protection is a key research topic at home and abroad.
Lower deceleration during gear transmission noise has become an important research topic in the industry, many scholars at home and abroad with the change of tooth mesh stiffness in gear transmission gear as the main factors of dynamic load, vibration and noise. With the method of repair, the dynamic load and velocity fluctuation are minimized to achieve the aim of reducing noise. This method proved to be a more effective method in practice. But in this way, the process needs to have the repair equipment, the general, small factory often cannot carry out.
After years of research, put forward by optimizing the gear parameters, such as coefficient of displacement coefficient, depth, pressure Angle, center distance, make the meshes to minimize the impact velocity, the recess action impact velocity and meshes into impact speed ratio in a certain scale, reduce or avoid the design method of gear meshing pitch shock, also can obviously reduce the reducer gear noise.
