For ordinary gears to produce abnormal noise, we must first check whether the gear's accuracy and geometric dimensions meet the design requirements.Check whether the distance in the gear box is out of tolerance, which affects the assembly size of the gear.

Gear abnormal noise solution:

1. Ensure that the gears can be meshed correctly,

2. Have good accuracy,

3. Maintain a smooth tooth surface and proper tooth clearance

4. Has good lubrication,

5. Tooth shape and tooth direction are modified in time,

6. Try to choose small modulus gears,

7. The smaller the pressure angle, the larger the height and the larger the coincidence degree.Equal slip ratio
