The noise produced by planetary reducer is mainly caused by the friction, vibration and impact of gear transmission system. How to reasonably reduce the noise and make the mixer more in line with the requirements of environmental protection is also an urgent problem to be solved. One of the most important problems in the world. Reducing the transmission noise of planetary reducer has become an important topic in manufacturing industry. Many experts and scholars in the world regard the change of gear transmission bending stiffness as the main factor of gear transmission load, vibration and noise. In order to reduce the noise, the fluctuation is reduced by adjusting the load and speed. This method is more reasonable in combination with practice. However, in this way, the mechanical equipment must be adjusted in the manufacturing process, which is usually impossible for many small and medium-sized processing plants.
