Abstract
A streamlined, self-cleaning, non-driven pulley having a center flange extending radially from a center hub which has axially extending radial ribs on either side of the flange. The space between adjacent ribs is filled by a web sloping radially inward toward the axis of rotation of the pulley and axially outward from the center flange. In operation with a belt having two parallel longitudinal rows of internal driving lugs, the pulley flange contacts the belt between the lug rows to support the belt. Each belt lug is supported by the ribs as it passes over the pulley to maximize the width of support to the belt tensile member while under working load.
