  • Item Details
  •  This "Planetary Gear Assembly" or epicyclic gear train is a system consisting of one or more outer gears, or planet gears, revolving about a central, or sun gear. The apparatus was named after its first program, modeling of the movements of the planets in the heavens. At around 500 BCE, the Greeks devised the notion of epicycles, of circles going on the circular orbits and with this theory could approximate the elliptical path of the moon through the celestial sphere.
