Products: Mechanical Transmission Systems Planetary Gear, Large Transmission Ratio

1. A planetary gear is a special type of gear that is usually located between two sun wheels and exhibits the motion characteristics of a planet as it rotates. It usually interacts with one or more other gears to achieve the transmission and speed change of power. Planetary gears are used in many mechanical transmission systems, such as automobiles, aircraft, industrial equipment, and precision instruments.

2. The working principle of planetary gears is based on the interaction between gears. When the sun gear of a planetary gear is fixed, the rotation of the other sun gear or sun gear meshing with it will drive the planetary gear to rotate around its axis. At the same time, the rotation of the planetary gear will drive the rotation of another center wheel meshed with it, thereby realizing power transmission and speed change.
