  4. How to make the noise of reducer smaller...

The problem of loud noise has always been an inevitable problem of many mechanical equipment. The formation of noise is caused by the operation of mechanical equipment, and it is inevitable. Therefore, noise has always been a "unsolvable" problem. However, although noise is inevitable, we can try our best to reduce it. Next, the reducer manufacturer will introduce it to you:


For a standard reducer, the manufacturing accuracy of the gear determines its noise value. The main function of the reducer gear is to transmit the speed and torque, so the requirements for its gear manufacturing accuracy and its working stability are the main concerns. Gears with high working stability not only have a long service life, but also have 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 instantaneous speed ratio of the gear. Its error is the rotation angle error that occurs many times per rotation of the gear. It makes the gear collide and vibrate during the meshing process, thus generating gear noise, which is a high-frequency impact sound. For a gear, the factors that affect the working stability are its base pitch error and its involute tooth profile error.

The motion accuracy of the gear refers to the accuracy of transmission motion, 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 error of the circumferential pitch within one rotation of the gear caused by the radial runout of the gear ring will generate low-frequency noise. However, if the accumulated error of the circumferential pitch increases, it will cause gear meshing impact and angular velocity variation. At this time, the noise will obviously increase and make a rumble.
