The choice of planetary reducer is very important for the motor. When selecting a planetary reducer, the selection of the reducer gear is a very important part. Because the gears are not matched and unreasonable, the reducer will not operate normally. How to choose the planetary reducer to select the gear?
1. When selecting a gear, the planetary reducer should pay attention to the hardness of the working tooth surface of the pinion gear is slightly higher than the working tooth surface hardness of the large gear.
2, the use of a smaller pressure angle can reduce the running noise, comprehensively consider the impact of strength, usually take the standard value of 20 ° C. When the structure allows, the use of helical gears should be given priority, and the vibration and noise are greatly reduced compared with the spur gears. Generally, the helix angle is selected between 8 ° C and 20 ° C.
3. Under the economic ability that the user can withstand, the accuracy level of the gear should be improved as much as possible. High-precision grade gears produce much less noise than low-precision grade gears.
4. Under the premise of satisfying the bending fatigue strength, when the center distance of the planetary reducer is constant, more teeth should be selected, which can improve the coincidence degree, make the transmission smooth and reduce noise. Under the premise of meeting the transmission requirements, the number of teeth of the large and small gears should be made as large as possible, so as to disperse and eliminate the influence of the gear manufacturing error on the transmission, and also avoid the teeth of the large and small gears periodically meshing with each other, so that the transmission is stable. Reduce noise.
The above is the method of selecting the planetary reducer gear. What we can see is that the use of the planetary reducer is an aspect that must be paid attention to for the choice of gears. I hope that the introduction of Dongguan Ji Chuang Xiaobian can help everyone.
