    Abstract: A high speed ratio drive system is formed of planet rollers, each having varying diameter, an outer fixed ring in contact with one diameter of the planet rollers, and an outer drive ring in contact with another diameter of the planet rollers. An inner drive element is provided by a sun drive roller in contact with the planet rollers or by a planet carrier. Preferably the system has an axial reflective symmetry minimizing twisting forces on the planet rollers.

    Abstract: A speed reducer drive can drive an output relative to a fixed ring using planet rollers having different diameter in contact with the output and fixed ring. Elements of the device can be formed of axially arranged segments for ease of construction. Backlash may be removed by manipulation of the drive before tightening segments of the rollers to fix the segments together by friction. The rolling contacts between elements can include a mix of geared contacts for better torque and ungeared contacts to act as bearing surfaces. Geared or ungeared surfaces may be tapered. Elements may be axially adjustable relative to each other, allowing backlash to be removed in combination with taper.
