Abstract
A continuously variable transmission has a main shaft rotating about a longitudinal axis. An input disk and output disk are fixed to the main shaft. An idler disk that rotates about and translates along the main shaft is mounted between the input and output disks. A plurality of conical input rollers engage mating surfaces on the input disk and the idler disk. A plurality of output rollers engage mating surfaces on the output disk and the idler disk. The input and output rollers move in planes orthogonal to the longitudinal axis to vary the drive ratio of the transmission. Input gears are connected to rotate coaxially with the input rollers, and output gears are connected to rotate coaxially with the output rollers. The rollers translate relative to the gears. Ring gears engage the input and output gears to input and output power. Alternatively, power can be input or output through one of the rollers.
