ABSTRACT:
A pulley configuration which increases the contact area between the pulley tooth tips and the land area of the belt teeth. The increased contact area reduces land area wear between belt teeth. The pulley tooth tip has a longitudinal cross-sectional contour partially composed of two substantially circular arcs connected by a line segment which is substantially straight or slightly curved. The length of the line segment is from 5 percent to 100 percent of the width of the belt tooth on which the pulley is used, and preferably between 6 percent and 33 percent of the width of the belt tooth. The pulley in combination with a toothed belt forms a positive power transmission system.
