Abstract:
1. A variable speed transmission, comprising: a longitudinal axis; a plurality of balls distributed radially about the longitudinal axis, each ball having a tiltable axis about which it rotates; a rotatable input disc positioned adjacent to the balls and in contact with each of the balls; a fixed output disc positioned adjacent to the balls opposite the input disc and in contact with each of the balls; a rotatable idler having a constant outside diameter and positioned radially inward of and in contact with each of the balls; a cage, adapted to maintain the radial position and axial alignment of the balls and that is rotatable about the longitudinal axis; and an idler shaft connected to the idler adapted to receive a torque output from the idler and transmit the torque output out of the transmission.
