How to control hydraulic winch noise

There are many sources of hydraulic winch noise, but in essence, it is the result of impact and vibration. Generally speaking, it is caused by poor meshing quality and unstable motion of the gear, which results in instantaneous acceleration in motion. The noise of the winch produced by our company is generally within the standard range, but occasionally the noise exceeds the standard. Since most of the products are qualified, the unreasonable factors of design and process should be eliminated.
