Getriebe zur Erzeugung eines ungleichfoermigen Abtriebes aus einem gleichfoermigen Antrieb

摘要

A drive assembly or gear unit is formed with a drive unit which is rotatably supported on a power output shaft between two bearing positions on the output shaft. The drive unit includes a pair of crankshafts which are offset relative to each other by 180 DEG , with each of the crankshafts carrying planet wheels which mesh with a stationary sun gear. The crankshafts are formed with cranks which cooperate with the arms of a twin-armed rocker member which is rotatably affixed to the output shaft in order to apply driving force thereto.
