Planetary reducer & gearbox is a kind of transmission mechanism. It utilizes the speed transducer of the gearbox to reduce to the turnover number of the motor to the required one and obtain a big torque. How does a planetary gearbox work? We can learn more about it from the structure. The main transmission structure of the planetary gearbox is a planet gear, sun gear, and ring gear. a ring gear is located in close contact with the internal gearbox case. The sun gear driven by the external power lies in the center of the ring gear. The rotation of the planet gears drives the output shaft connected with the carrier to output the power.
