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.

Abstract: A torque transfer device has plural planets arranged for planetary rotation about one or more sun gears and within one or more ring gears. Each planet includes at least one planetary gear set comprising plural planetary gears connected to rotate together, but having a different diameter to form a differential gear system. To improve load sharing, the plural planetary gears of each planetary gear set may have a different helical angle, the plural planetary gear sets being axially movable with respect to one another. Alternatively or in addition, the planetary gears may be made flexible with respect to radial forces.

Abstract: A planetary gearbox with two rows of planets between an inner race and a coaxial outer race. An input gear may also mesh with the inner planets or the outer planets. To avoid unmeshing of the gears due to twisting from the applied torque, a camming effect may be used in which applied torque generates a radial preload. The gears that mesh with the input gear may do so at portions of the gears that also mesh with a corresponding one of the inner or outer race. The planets may be geared with axial portions with different helix angle. The inner race or outer race may be formed of two components geared with different helix angle to mesh with the different axial portions of the planets. By using these different components, assembly is eased as the components can be slid onto the planets axially.
