VARIABLE SPEED TRANSMISSION

摘要

A variable speed transmission drives or is driven by a shaft (12); the torque transmitted is directly proportional to the degree push rods (18) are extended by the extendable eccentric cam (32). The rotation of a variable displacement cam (32) mounted on a shaft (12) selectively forces a series of circumferentially mounted retractable push rods (18) or roller bearings (20) against an internal cyclical periodic track (14) to effect rotation of a case (10).
