As an important part of the gear, I believe that readers know more about it. They must also know that the gear wears after a period of operation. If the wear is severe, the more direct manifestation is the generation of noise.The appearance of gear noise has a very good effect on work. It needs to be replaced or reinstalled. What are the main gear noise factors? I will analyze it here for everyone.

　　Due to the excitation of the dynamic meshing force, the gear system vibrates, thereby causing the vibration and noise of the gear system. Therefore, the noise intensity of the gear system is not only related to the dynamic excitation force of the gear tooth meshing, but also related to the wheel body, transmission shaft, bearing and The structural form, dynamic characteristics of boxes, etc., and the transmission characteristics of dynamic meshing force between them are related.Specifically, the main factors that cause gear noise are: (1) the influence of working conditions, gear types, design parameters, machining and assembly accuracy and errors on the dynamic meshing force; (2) establishing a gear system according to the type of gear Analyze the vibration form of the system under the action of dynamic excitation force; (3) The vibration state of each component in the gear system, the propagation process and propagation characteristics of the vibration from the meshing gear teeth to the surface of the box; (4) For Acceleration noise needs to be discussed how they are transmitted to the outside through the cabinet.

　　The existence of these reasons will lead to the generation of gear noise. If you want to avoid the noise, you can improve the operation of the gear through the above introduction.With the advancement of production technology, the types of gears have become more diverse. Therefore, it is also very important for everyone to choose the right type of gear. If the gear is too large, noise will definitely occur.The editor of this article will first introduce it here, I hope everyone can understand.
