A friction variable-speed drive for drive of three units that includes a body with installed in it, with possibility of rotation, spring-supported disc, cylindrical roller with mechanism of displacement, drive unit that interacts with the disc and mechanism for adjustment of gear ratio. Additionally the second and the third units are included, the second and the third rollers with mechanism for displacement and adjustment of gear ratios. The rollers are made spherical, cut at two sides with conical, placed oppositely depressions and are installed on spherical axles. The mechanisms of displacement of the rollers are arranged as con-rods connected with one ends to spherical axles, and additionally the first, second and third spline shafts with toothed gearings are installed. |
