[1] This planetary gear set, commonly used in automatic transmissions, is constructed from two gear pairs, ring–planet and planet–planet. The gearset provides four forward gear ...
The sun and planet gear converted the vertical motion of a beam, driven by a steam engine, into circular motion using a 'planet', a cogwheel fixed at the end of the connecting rod (connected to the beam) of the engine.
