TOOTHED PULLEY AND MEANS OF TRANSMISSION RELATED THERETO

摘要

A toothed pulley is provided which includes a plurality of grooves alternating with a plurality of teeth. The flank of each groove is joined to the head of the adjacent tooth by means of a connection formed of at least two convex curvilinear segments and a recess. The curvilinear segments are tangent to the end of the flank and to the terminal point of the tooth head delimitated by the outer circumference of the pulley respectively. The pulley engages with a toothed belt which includes a connection between the tooth flank and the adjacent groove, which may be in the form of a parabolic arc.
