TOOTHED BELT AND MEANS OF TRANSMISSION RELATED THERETO

摘要

TOOTHED BELT AND TRANSMISSION MEANS RELATED THERETO (Case 8814) A toothed belt (1) having between its teeth (7) and the grooves (8) adjacent to the said teeth curvilinear connection segments (17) whose ends are located on the end of the tooth flank and the base line delimiting the grooves. The first end (18) of the curvilinear connection segment coincides with the fir t terminal point of an arc (20) tangent to the end of the flank and to the base line delimiting the grooves, the second end (19) of the curvilinear segment being located between the second point (21) of the said arc and the point of intersection (22) of the central axis of the groove L-L and the base line. Preferably, the toothed belt forms part of a transmission means including pulleys in which at least one of the pulleys is provided with teeth (24) filleted laterally with respect to the adjacent grooves (23) by means of curvilinear segments (31, 32) shaped to correspond to the curvilinear connection segments of the belt. Preferably, the curvilinear connection segments of the belt and of the pulley are parabolic arcs.
