ABSTRACT:
A transmission system including two axially spaced torus discs or rotors, one serving as an input and the other as an output and between which there is a set of circumferentially spaced drive rollers in frictional rolling contact with part toroidal surfaces on the discs, each roller being mounted in a bearing structure which can tilt about an axis at right angles to the axis of rotation of each roller to vary the distances from the gear axis at which the roller engages the two discs respectively to vary the ratio of the gear, means being provided for moving each roller bearing structure generally tangentially of the gear axis, and arranged to apply a force to said structure in a direction non-parallel with respect to the plane which is perpendicular to the gear axis and there being means for accommodating the effective movement of the roller bearing axes relatively to the gear axis in a direction parallel to the gear axis.
