Several small methods to improve the performance of planetary reducer

2021-10-05

For the planetary gear reducer, its gear is an important and weak component. Some enterprises have made the planetary gear reducer work with high load for a long time to improve the working efficiency, and the load of the gear is also increasing, thus increasing the failure rate of the equipment. In order to meet the needs of various enterprises, today I will tell you some small methods to improve the load and performance of the equipment.

1. Gear modification

Modifying the tooth profile and tooth root end modification is a good way to modify the performance of the heavy drive gear. It is used for heavy gear. The tooth end modification of the gear is usually prevented by the end of the overload tooth dislocation.

2. Adjust the displacement coefficient

If the displacement coefficient is selected correctly, the bearing capacity of the gear can be increased by 20%~30%.

3. Accuracy and error of control device

It is not only related to the gear surface strength of precision, but also the absolute value of pitch error. If the tooth pitch error is large, the rolling pressure applied to the gear tooth is also large.

4. Increase tooth width

When the outer diameter of the planetary gear reducer is constant, the width is increased, and the internal gear can effectively improve the bearing capacity of the gear.

5. Add gear module and increase tooth profile angle

The outer diameter of the planetary reducer remains unchanged, so it is necessary to increase the bearing capacity, properly increase the gear modulus and reduce the number of gear teeth.
