How to make reducer noise less

The problem of high noise has always been an inevitable problem for many mechanical equipment. The formation of noise is caused by the operation of mechanical equipment and is inevitable. Therefore, noise has always been an "unsolvable" problem. However, although the noise is unavoidable, we can reduce it as much as possible. Next, the reducer manufacturer will introduce:

For the standard reducer, the manufacturing accuracy of the gear determines its noise value. The main function of reducer gear is to transmit speed and torque, so the requirements for its gear manufacturing accuracy and its stability are mainly concerned. The gear with higher working stability level not only has a long service life, but also has much less impact and vibration in transmission, so the noise is smaller.

In addition, the working stability accuracy of the gear is also required to limit the change of the gear's instantaneous speed ratio. The error is the angle error that occurs many times per revolution of the gear. It makes the gear produce impact and vibration in the meshing process, resulting in gear noise, which is a high-frequency impact sound. For a gear, the factors affecting its working stability are its base pitch error and its involute tooth profile error.

The movement accuracy of the gear refers to the accuracy of the transmission movement, that is, the maximum error value of the rotation angle error of the gear per revolution cannot exceed a certain limit. Because the gear motion accuracy is a large periodic error, and the accumulated pitch error caused by the radial runout of the gear ring within one cycle of gear rotation will produce low-frequency noise. However, if the accumulated pitch error increases, it will cause gear meshing impact and angular velocity changes. At this time, the noise will increase significantly and give out a rumble.
