1. Effect of gear processing on gear reducer noise. Noise has a great influence on work stability accuracy, gear contact accuracy, gear motion accuracy, assembly accuracy, etc. If you want to reduce the noise of the gearbox, you must know the cause of the noise. The noise of the gearbox is caused by vibration caused by periodic cross-change forces caused by gear meshing during machine operation. The main criterion for evaluating the quality level of the cylindrical gear reducer is its noise value. With the internationalization of product standards, there are strict restrictions on the noise value of the gearbox in China, which requires the study of the noise control of the gearbox.
(1) The effect of gear processing error on noise. Reducing and controlling gear noise is the basis for reducing gear noise. In order to reduce gear noise, both structural design and gear accuracy must be considered.
1. Structural design requirements for low noise gears. The effect of gear structure design on noise is very important. The ideal design is to maximize the bending strength of the gear teeth, select a larger gear changer and a suitable helix angle, and increase the meshing coefficient in order to reduce noise.
2. The effect of gear manufacturing accuracy on noise. For standard series reducers, the manufacturing accuracy of the gear determines its noise value. The main function of the gear of the reducer is to transmit speed and torque, so its working stability level is the main requirement of its gear manufacturing accuracy. Gears with high working stability levels not only have a long service life, but also have less impact and vibration in the transmission, so limiting the working stability error of the gears is the key to reduce gear noise.
