How to deal with the noise of gear reducer

When there is a problem with the gear reducer, we should check it in time to solve the problem, as long as we have a certain understanding of the possible problems with the gear reducer. Today, we mainly introduce how to deal with the noise of the gear reducer.

1. Damage of transmission parts

Damage of transmission parts During installation, transmission parts are damaged due to improper operation, resulting in inaccurate or unstable movement. Due to the damage, high-speed moving parts are damaged by oil film; The moving parts are artificially unbalanced; Vibration and noise are produced. This reason must be paid attention to and avoided during installation. Irreparable damaged parts must be replaced to ensure a stable noise level.

2. Vibration reduction and blocking measures

Vibration reduction and blocking measures when installing a reducer, it is necessary to avoid the resonance between the fuselage and the foundation bracket and connector as much as possible. Noise is generated. Gear reducers usually have one or more gears inside the gear motor.

Resonance occurs in some speed ranges. Except for design reasons, there is a direct relationship between installation and resonance position without empty test, and corresponding vibration reduction or blocking measures are provided. Some reducers that need low transmission noise and vibration should use high toughness and high damping substrates to reduce noise.

3. The reducer motor parts of the energy-saving reducer are loose.

Due to the looseness of various parts (such as bearing pre-tightening mechanism, shafting positioning mechanism, etc.), the system positioning is incorrect, the abnormal position is engaged, the shaft system moves, vibrates and produces noise.

This series needs to start from the design structure, try to ensure the stability of the connection of various mechanisms, and adopt various connection methods.

Adjusting the geometric accuracy of the assembly is because the geometric accuracy of the installation does not meet the requirements of the standard, which leads to the resonance and noise of the gear reducer assembly. This should be directly related to improving the installation process and increasing tools to ensure the overall quality of the assembler.
