Components
A planetary reducer typically consists of the following key components:
Sun Gear The central gear around which the planet gears revolve.
Planet Gears Multiple gears that rotate around the sun gear and mesh with both the sun gear and the ring gear.
Carrier The structure that holds the planet gears in place and rotates, providing the output of the gear system.
Ring Gear The outer gear with internal teeth that mesh with the planet gears.
