Abstract

PURPOSE:To improve the efficiency of transmission by interposing a rotatable gear between teeth provided on opposed cam surfaces of cylindrical end face cams giving a thrust to a driven rotor to press a driven frictional wheel against a drive frictional ring by the action of said cam. CONSTITUTION:When 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 and said wheels 54, 56 are pressed against said ring 39 by the action of cylindrical end face cams 65, 69 harder than they are previously. Teeth 65c, 69c are provided respectively on opposed cam surfaces of said cams 65, 69 to interpose a rotatable gear 73 between these teeth rows. Thus, the differential motion between both cams 65, 69 is securely ensured by the engagement of the teeth rows and the gear 73 without any slip to reduce resistance along with the action of said cams 65, 69 for secure operation. Thus, the slip along with the increase of load can be remarkably reduced to improve the efficiency of transmission.
