How to reduce the noise of the reducer

The high noise of the reducer has always been an inevitable problem of many mechanical equipment.Noise is caused by the operation of mechanical equipment and is unavoidable.Therefore, noise has always been a 'unsolvable' problem.But while noise is unavoidable, we can do our best to minimize it.Next, Restore Maker will introduce:

For standard reducers, the manufacturing precision of the gears determines its noise value.The main function of reduction gears is to transmit speed and torque.Therefore, the requirements of gear manufacturing accuracy and its working stability are the main issues.Gears with high working stability not only have a long service life, but also have less impact and vibration in the gearbox, so they are less noisy.

In addition, the working stability precision of the gear is also required to limit the change of the instantaneous speed ratio of the gear.The error is the rotation angle error that occurs many times when the gear rotates.It causes the gears to bump and vibrate during the meshing process, which causes the noise of the gears, which is a high frequency impact sound.For gears, the factors that affect the working stability are its base pitch error and its transparent profile error.

The motion accuracy of the gear refers to the accuracy of the transmission motion, that is, the maximum error value of the rotation angle error of each rotation of the gear cannot exceed a certain limit.Since the motion accuracy of the gear is a large periodic error, the cumulative error of the gear rotation due to the radial runout of the gear ring will generate low-frequency noise.However, if the cumulative error in circular pitch increases, it will cause jerks between gears and changes in angular velocity.For now, the noise will obviously increase and there will be a rumbling sound.
