Gear manufacturers analyze why noise occurs when gears mesh
Gear machining is mainly a process in which the specific structure and precision of the gear are obtained by mechanical methods. Noise sometimes occurs during the machining process. The gear noise is mainly caused by the vibration caused by the meshing collision between the gears. out the sound.
What are the reasons for the noise caused by the meshing of gears:
In the process of meshing between the two gears, because the gear teeth are elastically deformed, the load of the previously meshed gear teeth will be relatively smaller, and they will immediately recover to the load position, giving a tangential acceleration to the gear body, plus the original meshing gear teeth. The bending deformation and gear manufacturing error under the load make the gear teeth disengage from the meshing collision during the entire meshing process, forming the so-called meshing impact force.
Under the action of this excitation, the gear will also excite the vibration of the gear, which will generate noise and propagate through the air and solid media. Therefore, the main cause of noise in gear machining is the vibration generated during the meshing process.
It is very important to control the gear transmission noise now, and the requirements for the transmission error of the equipment in industrial production are becoming more and more strict, so it is necessary to find a way to control and avoid the generation of noise.
The above is the introduction of the reasons why the gear manufacturers generate noise when analyzing the gear meshing.
