Pulley for positive systems aperfeicoada thrusters

摘要

In a pulley configuration which is adapted to increase the contact area between the pulley tooth tips and the land area of the positive drive belt teeth, on which the pulley is used, each pulley tooth tip has a longitudinal cross-sectional contour partially composed of two substantially circular arcs (24, 25) connected by a line segment (31) from 5% to 100% of the width (59) of the belt tooth on which the pulley is used, and preferably between 6% and 33% of the width of the belt tooth.
