The noise of reducer is a kind of noise pollution and also a common mechanical fault in maintenance. In order to reduce the gear noise of reduction machine, the cause of gear noise increase must be determined accurately first. When the cause of the noise increase is found, the defective gear or related parts can be replaced and repaired, and the assembly of the defective parts can be adjusted again, so that the equipment can restore the original noise level.

Main factors influencing the increase of gear noise of reduction gear:

1. There is influence of external vibration sources;

2. The rotation eccentricity of the gear rotation system increases;

3. Serious failure of tooth surface.

Common methods for determining the noise source of reduction gear:

1. Use the transmission diagram for analysis;

2. Analyze and judge by intuitive observation;

3. Red powder coating for judgment;

4. Use the metered measurement method to judge.

Deceleration and noise increase have a certain impact on our equipment, not only the sound is bad, but also affect the work of the reducer, when the noise of the reducer increases, even if the processing.
