ABSTRACT:
A mechanical transmission (10) is disclosed which utilizes a plurality of sets of rollers (94-104) with associated rotating discs (74, 152, 170 and 196). The rollers (94-104) are ellipsoidally shaped with concentric rows of teeth thereon. The associated discs (74, 152,170 and 96) have concentric rows of holes aligned for receiving the roller teeth. The rollers (94-104) are caused to tilt about a center shaft (88) by a control link (216) to engage various of the rows of teeth on the rollers (94-104) with the associated discs (74, 152, 170 and 196). Tilting of the rollers (94-104) in differing directions to differing degrees produces varying input to output drive ratios.
