Abstract:
A transmission comprising:a shaft;a rotatable driving member rotatably mounted on the shaft;a rotatable driven member rotatably mounted on the shaft;a plurality of power adjusters frictionally interposed between the rotatable driving member and the rotatable driven member and adapted to transmit power from the rotatable driving member to the rotatable driven member;a rotatable support member located concentrically over the shaft and between the power adjusters, and frictionally engaged to the plurality of power adjusters, so that the power adjusters each make three point frictional contact against the driving member, the driven member, and the rotatable support member;a plurality of pivot supports, one pivot support for each of the power adjusters, the pivot support adapted to modify an axis of rotation of each of the power adjusters;a ratio changer slidably mounted along the axis of the rotatable driving member and configured to pivot the pivot supports;a first compression member rotatably disposed over the shaft and adapted to direct the rotatable driving member toward the rotatable driven member; andwherein the first compression member includes a roller cage assembly having a plurality of rollers, each of the rollers configured to engage one of a plurality of shallow grooves on the rotatable driving member, the roller cage assembly rotatably affixed to the shaft.
