The selection of gear parameters for planetary reducers has a significant impact on noise. Specifically, the planetary reducer uses high-quality low-carbon alloy steel through gear grinding process to reduce noise and vibration. However, when using it and facing paired combinations, many operators need to pay attention to the working tooth surface hardness of the small gear being slightly higher than that of the large gear.

Under the condition of meeting the strength requirements, spiral elevators can consider using gears of different materials to mesh and achieve noise reduction.
1. The use of a smaller pressure angle can reduce the operating noise. Considering the impact of strength, the value is usually 20 °.
When the structure allows, priority should be given to using helical gears, which have a significant reduction in vibration and noise compared to spur gears. Generally, the helix angle is required to be selected between 8 ℃ and 20 ℃.
On the premise of meeting the bending fatigue strength, when the center distance of the reducer is constant, a larger number of teeth should be selected to improve the fit, make the drive stable, and reduce noise. On the premise of meeting the driving requirements, the number of teeth of the large and small gears should be made as prime as possible to disperse and eliminate the impact of gear manufacturing errors on the drive. It is also possible for certain teeth on the large and small gears to periodically mesh with each other, thereby making the drive stable and reducing noise.
3. Under the affordability of users, the accuracy level of gears should be raised as much as possible during design. Precision grade gears generate much less noise than low precision grade gears.
When producing planetary reducers, in order to reduce the noise of gear reducers, Zhaowei Electromechanical selects a smaller backlash when driving with pulsating rotation. For a more balanced load, a slightly larger backlash should be selected. Thus producing low-noise and high-quality planetary reducer products.
