Abstract
PURPOSE:To improve the efficiency of transmission by disposing balls on the cam surface of a cylindrical end face can giving a thrust to a movable driven rotor constitute a driven frictional wheel to be pressed against a drive frictional ring by the action of said cam. CONSTITUTION:If a slip takes place between driven frictional wheels 54, 56 and a drive frictional ring 39, a rotational phase difference takes place between a driven rotor 48 and a movable driven rotor 57 so that said wheels 54, 56 are pressed against said ring 39 by the action of cylindrical end face cams 65, 72 harder than they are previously. Namely, if the slip takes place between the frictional wheels, said cams 65, 72 act as a toggle joint for increasing a contact force between said wheels. By arranging balls 69 between the cam surfaces of said cams 65, 72 can be reduced the frictional resistance in the operation of cams provide a smooth cam operation, so that the slip along with the increase of load can be remarkably reduced to and improve the efficiency of transmission.
