A combined friction variable-speed driver includes a case with installed in it with possibility of rotation first spring-supported disc, cylindrical roller with mechanism of displacement that interacts with the disc and the first drive unit. Additionally the device has the second drive unit, second spring-supported disc that is kinematically through toothed gearings connected to the first disc, and the second roller with displacement mechanism. The rollers are arranged spherical, truncated at two sides, with opposite positions of depressions and installed on spherical axles. Mechanisms for displacement of rollers are arranged as con-rods connected to spherical axles and additionally the first and the second spline shafts with toothed hearings are installed. One of the wheels of those are connected to the first and the second unit, and the other wheels are fit to the first and the second spline shafts, with restricted stroke along those, and equipped with spline bushings arranged with possibility of rotation and displacement along the axles of the shafts and friction interaction with spherical rollers. |
