Planetary Wheel & Sun Gear

In a simple planetary gear mechanism,the sun wheel is located in the center of the planetary gear mechanism,and the sun wheel and the planet wheel are always engaged.

The two outer gears engage and rotate in opposite directions.Just as the sun is at the center of the solar system,the sun's wheel gets its name from its position.

In addition to the planet wheel can rotate around the supporting axis of the planet rack,in some conditions,it will also be driven by the planet rack,rotating around the central axis of the sun wheel,which is like the rotation of the earth and the revolution around the sun.When this happens,it is called the transmission mode of the planetary gear mechanism.
