Planetary gearbox
also known as a planetary reducer system or epicyclic gear train, is a type of gear mechanism consisting of one or more outer gears (planet gears) revolving around a central (sun) gear. Typically, these systems also include a ring gear (annulus) that meshes with the planet gears. The planet gears are mounted on a movable carrier which also connects to the output shaft of the gearbox. Here's a breakdown of its components and functions:
