The noise of planetary reducer mainly comes from friction, vibration and collision of transmission gears. How to effectively reduce noise is a very important research direction.
Reducing the noise of planetary reducer gear transmission has become an important research topic in industry. Many scholars at home and abroad regard the change of gear meshing stiffness as the main factor affecting the dynamic load, vibration and noise of gears. In order to reduce noise, the dynamic load and speed fluctuation are minimized by improvement. Practice has proved that this method is effective. However, with this method, molding equipment is required technically, and the vast number of small and medium-sized factories are often unable to implement it.
After years of research, a gear design method is put forward. By optimizing gear parameters such as modification coefficient, tooth height coefficient, pressure angle and center distance, the influence of meshing pitch circle is reduced or avoided, and the meshing impact speed is minimized. The ratio of meshing impact speed to meshing impact speed is within a certain numerical range, which can also significantly reduce the gear noise of planetary reducer.
The above is an introduction to the noise problem of planetary reducer.
