Epicyclic gearing - Wikipedia
Overview. Epicyclic gearing or planetary gearing is a gear system consisting of one or more outer, or planet, gears or pinions, revolving about a central sun gear or sun wheel. Typically, the planet gears are mounted on a movable arm or carrier, which itself may rotate relative to the sun gear.Epicyclic gearing systems also incorporate the use of an outer ring gear or annulus, which meshes ...
