Title:
TRANSMISSION MECHANISM
Document Type and Number:
Japanese Patent JPS5377960
Kind Code:
A
Abstract:
A transmission system comprising 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 rotatably mounted in a bearing structure which can tilt about an axis at right angles to the axis of rotation of each roller so as to vary the distances from the gear axis at which the roller engages the two discs respectively, thus varying the drive ratio of the gear and means for moving each of the roller bearing structures generally tangentially with respect to the axis and arranged to apply a force to said structure in a direction to vary the castor angle, there being means for accommodating effective movement of the roller bearing axes relatively to the gear axis in a direction parallel to the gear axis.
