A continuously variable mechanical transmission comprised of two wheels, either friction or toothed, of which one or both are in the shape of hemispheres. A hemisphere wheel is mounted through a bearing on a fork with two pivots attached to the inner race of the bearing, allowing the wheel to rotate around two perpendicular accesses. The center of the wheel is attached tot he shaft through a double universal joint or a flexible shaft. The other wheel can be a regular narrow wheel fixed to the second shaft. By rotating the hemisphere wheel around the fork pivots the diameter of the wheel engaged with the second wheel is increased or decreased allowing the transmission rate to vary. |
