"WebbIn a planetary gear set you have the sun gear (center), planet gear (can be any number of them depending on the math), and the ring gear which is the outside shell which has teeth facing inwards. You can drive any layer (s,p or r). If you drive the planet gears and keep the sun gear stationary the ring gear becomes the output and rotates faster. " - Landing gear shimmy
