ABSTRACT:
An infinitely variable ratio traction drive comprises a pair of drive cones driven in opposite directions by an input shaft. A number of intermediate drive shafts with intermediate drive cones splined onto them extend radially with respect to the input shaft so that the intermediate cones are in driving contact with the input drive cones. The intermediate shafts are connected to the output shaft by bevel gears, a planetary drive, or a traction drive or any combination of these. The drive ratio can be varied by altering the radial position of the intermediate cones on their respective shafts.
