A simple planetary gear set consists of three parts: a sun gear, a carrier with planetary pinions mounted to it, and an internally toothed ring gear. The sun gear is located in the center of the assembly. It meshes with the teeth of the planetary pinion gears. Planetary pinion gears are small gears fitted into a framework called the planetary carrier. The planetary carrier is designed with a shaft for each of the planetary pinion gears. The carrier and pinions are considered one unit—the mid-size gear member. The planetary pinions surround the sun gear and are surrounded by the ring gear, which is the largest part of the gear set. The ring gear acts like a band to hold the gear set together and provide great strength to the unit.
