Several methods to improve the performance of planetary reducer

For planetary gear reducer, its gear is a more important and weak part. In order to improve the work efficiency, some enterprises make the planetary reducer work with high load for a long time, and the load of the gear is also increasing, so as to increase the failure rate of the equipment. In order to meet the needs of various enterprises, we will tell you some small methods to improve the load and performance of the equipment.

1. Gear modification

Modification of the tooth profile and tooth root end modification is a good method to modify the heavy drive gear and improve the performance. It is used for heavy-duty gear. The tooth end modification of the gear is usually prevented by the end of 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

Not only with the accuracy of the gear grade tooth surface strength, but also pay attention to the absolute value of pitch error. If the pitch error is large, the rolling pressure applied to the gear teeth is also large.

4. Increase tooth width

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

5. Add gear module and increase tooth profile angle

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