Abstract
A torque transfer device has a ring gear and inner and outer planet gear sets, which may not be orbiting but rotating in fixed positions relative to a housing. One of the gear sets may comprise compound gears. There may also be a sun gear connected to a planet gear set. The sun gear may be an input and the ring gear an output for a reducing gear system to act as a torque amplifier. The gears may be tapered and there may also be an axial force applied to one of the gear sets to tighten the meshing between the tapered gears. One of the gear sets, for example a gear set to which an axial force is applied, may be floating.
