The sun gear acts as the central gear in a planetary gear system, receiving rotation from the input shaft. it exerts force on the planetary gears, causing them to rotate. The inner ring gear is fixed, the planetary gears will also revolve along the trajectory of the inner ring gear while being driven by the sun gear. The planetary gear is connected to the output shaft through a planetary carrier, so when the planetary gear rotates and revolves, it will ultimately transmit the rotational force to the output shaft, achieving the effect of deceleration and increasing torque.
Advantages of Planetary Gear Box
1. High Torque Density:
Due to the compact design, can transfer the maximum amount of torque in a limited space.
2. Precise and Stable:
Central loading concentration, no lateral pressure on the gear teeth, and the power is transmitted radially.
3. Long Service life:
Distribute the load among different gears, decreasing the strain on individual gears.
