A toroidal transmission includes a stator having a plurality of helical races that together define a toroidal cavity having an axis, and first and second shafts rotatable about the axis, the first shaft carrying a worm, the second shaft carrying a plurality of multiple-tooth rotors arranged in a circle about the axis so that the rotor teeth are facing toward the axis and drivingly engage the worm and the rotor teeth facing away from the axis extend into the cavity and drivingly engage the races. The transmission has a first mounting plate having an opening therein receiving the first shaft and a second mounting plate having an opening therein receiving the second shaft, the plates being positioned on opposite sides of the rotors perpendicular to the axis. The stator comprises a circular array of individual arcuate twisted ribs spaced apart about the axis, each rib having one end connected to the first plate and its other end connected to the second plate so that portions of the away-facing rotor teeth project into the spaces between the ribs, which spaces thus constitute the stator races. A method of assembling the transmission is also disclosed as are a method and apparatus for making the transmission's stator.
