Noise Reducer Methods

Oct 27, 2016

Reduced deceleration runtime gear drive noise has become an important research topic within the industry, many scholars at home and abroad have put the gear meshing stiffness of gear dynamic load, vibration and noise factors. Modification of the method, its dynamic load 

and speed fluctuations kept to a minimum, for the purpose of noise reduction. This approach has proven to be an effective method in practice. In this way, process modification is required on devices, the majority of medium and small plants are often impossible to implement.

After years of research, presented by optimizing the gear parameters, such as pressure coefficient of addendum modification coefficients, height, angle, distance, minimize the meshing impact speed, out impact speed to lighten the impact velocity ratio within a range, reduce or avoid impact design method of gear intermeshing pitch circle or reducer gear noise can be significantly reduced.
