How should the noise of gear reducer be handled
When there is a problem with the gear reducer, we should check in time to solve the problem, as long as we have a certain understanding of the possible problems of the gear reducer.
1. Transmission parts are damaged during installation, the transmission parts are damaged due to improper operation, resulting in inaccurate or unstable movement. Due to damage, high-speed moving parts are damaged by oil film; The moving parts are artificially unbalanced; Both produce vibration and noise. Be aware of this problem and avoid it during installation. Damaged parts must be replaced to ensure stable noise levels.
2. When installing the reducer, the resonance between the fuselage and the foundation bracket and the connecting piece should be avoided as far as possible. A gear reducer usually has one or more gears inside a gear motor. Resonance occurs over certain velocity ranges. In addition to design reasons, in the absence of empty tests, there is a direct relationship between the installation and resonance positions, and the corresponding damping or blocking measures. Some need low transmission noise and vibration reducer, should use high toughness, high damping substrate to reduce noise and vibration.
3. The reduction motor parts of the energy-saving reducer are loose. Due to the loosening of various components (such as bearing pretightening mechanism, shafting positioning mechanism, etc.), the system positioning is not correct, abnormal position meshing, shaft system movement. Vibration and noise generation, this series needs to proceed from the design structure, as far as possible to ensure the stability of all kinds of mechanism connection, using a variety of connection methods.
Adjusting the geometric precision of the assembly is because the geometric precision of the installation does not meet the requirements of the standard, resulting in the resonance of the gear reduction unit and the noise, which should be directly related to improving the installation process, increasing tools and ensuring the overall quality of the assembly personnel.
