Background

Planetary gears are gear systems whose axes of rotation, in addition to being able to rotate about their own axis of rotation like a fixed axis gear, also rotate with the planet carrier about the axes of the other gears. Rotation about its own axis is called "rotation", and rotation about the other gear axis is called "revolution", just like a planet in the solar system, and hence its name. Planetary gear transmissions have many unique advantages over conventional gear transmissions. The most remarkable characteristic is that power splitting can be carried out when power is transmitted, and the input shaft and the output shaft are on the same horizontal line. Planetary gear transmissions have been widely used in reduction, speed-increasing and speed-changing devices in various mechanical transmission systems. Particularly, it has found a great deal of application in aircraft and vehicles (particularly heavy vehicles) because of its "high load, high gear ratio" feature.
