Epicyclic gear systems have a long history of industrial use. As early as 1781, James Watt patented a sun and planet gear arrangement used in one of his early engines. However, advances in internal gear manufacturing did not parallel those in

Epicyclic gearing systems also incorporate the use of an outer ring gear or annulus, which meshes with the planet gears.” Annulus, Planets 

By varying the size of the sun and planets the gear ratio can be altered. The outlet drive could be taken either off the bar 'c' or if 'c' was fixed off the rotating annulus. Comparison of Epicyclic gearing to Tandem gearing. Advantages • The output may be reversed to requirement • Small size and weight for given ratio (approx. 5% of wheel

The planetary or epicyclic gearbox is made up of a carrier, the planetary gears, an outer ring with teeth that face inwards, commonly referred to as an internal gear, and the sun gear in the center. The solar gear spins when power is applied. The standard by which the planetary gears mesh with the sun gear determines how the sun gear revolves

An epicyclic gear train is a coaxial speed reducer or increaser stage comprised of a sun gear, planet gear(s), and a ring gear (Townsend 1992; Coy et al. 1985). The ratio attained from the gear train depends on the component that

Planetary gears, also known as epicyclic gears, were developed by the Greeks more than 2,000 years ago and were initially intended to help
