Planetary Gear Sets
Planetary Gear sets
A planetary gear set or an epicyclic gear train consists of a sun gear, planet gears, planet carriers, and an internal gear. A planetary gear set is usually installed in the gearbox. There are two types of planetary gear sets: single planetary gear sets and compound planetary gear sets. The planetary gear set is compact and lightweight. Its functional advantages are a high load and a large transmission ratio. Applications include cranes, automobiles, aircraft, and boats.
