Date Dec. 7, 1995Variable speed drive to be connected to a rotating driving shaft (5) and to a rotating driven shaft (6) includes at least two angled bearings (7, 7'), controller for controlling the orientation of the axis (13, 13') of each angled bearing (7, 7') adapted so that the axes are offset from one another, and transmission (9,9', 11, 11') adapted so that in each phase of the movement at least one of the angled bearings (7, 7') engages and at least one of the bearings (7, 7') does not engage. The controller is adapted to alter the slant of all the angled bearings (7, 7') on the basis of a signal for controlling the variation in the variable speed drive ratio.
