This Industrial Mini Planetary Gearbox is commonly used in automobiles, industrial machinery, and robotics. It uses a system of planetary gears to increase or decrease the speed of a rotating shaft. This gearbox consists of a sun gear, planet gears, and a ring gear. The sun gear is the central gear that is connected to the input shaft. This Industrial Mini Planetary Gearbox is mounted on a carrier and rotate around the sun gear. The ring gear is an outer gear that meshes with the planet gears. When the input shaft is rotated, the sun gear rotates and the planet gears rotate around it, causing the output shaft to rotate at a different speed than the input shaft. This allows the gearbox to increase or decrease the speed of the output shaft.
