Description

Technical Field

[0001] The present invention relates to the technical field of planetary gear processing, and in particular to a tool for processing planetary gears. Background Art

[0002] The planetary gear transmission system includes a central gear Za, an internal gear zb and multiple planetary gears Zc mounted on the planet carrier X. Each planetary gear Zc is externally meshed with the central gear Za and internally meshed with the internal gear Zb. The multiple planetary gear teeth Zc must be evenly distributed, and there must be gaps between adjacent planetary gear teeth Zc so that they cannot collide. This transmission system has many advantages. First, due to the rotation and revolution of the planetary gears, it can reduce the speed, increase the torque and output power to the outside. Secondly, by changing the length of the internal teeth, different reduction ratios can be obtained to meet the requirements of different loads. In addition, since the meshing accuracy of the planetary gears can be detected by an automatic meshing detection device, the performance of this transmission system can be guaranteed. When selecting the reduction ratio of the planetary gears, priority should be given to using a series close to the priority coefficient R10 recommended by the national standard. This allows the load torque and speed of the drive motor to be reasonably selected, thereby optimizing the heating, life and electromagnetic interference of the drive motor.
