Mechanism Planetary Reducer Hollow Shaft Mounting Low Backlash Planetary Gearing

Planetary reducer also known as a planetary gear 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:

Sun Gear The central gear around which the planet gears revolve.

Planet Gears Multiple gears that revolve around the sun gear and mesh with both the sun gear and the ring gear.

Ring Gear (Annulus) An outer gear that encircles the planet gears and meshes with them.

Planet Carrier A structure that holds the planet gears in place as they rotate around the sun gear.
