Functionality and Mechanism of Planetary Gearbox

Planetary gearboxes, also known as epicyclic gearboxes, are named so due to their resemblance to the solar system. The central gear, known as the sun gear, is orbited by planetary gears (hence the name), which are enclosed within a ring gear. The unique mechanism of this system allows for high torque transmission, high efficiency, and compactness compared to other types of gearboxes. The rotational motion and torque from the input shaft are transferred to the output shaft through the interaction of the sun, planet, and ring gears, providing a wide range of gear ratios in a small package.
