Abstract
An idler pulley is described for a front end accessory drive. The idler pulley includes plurality of angled spokes, such as angled ribs molded into the pulley to join an outer hub and an outermost belt interacting region. As the belt runs over the surface of the pulley, any defects on the belt running surface of the pulley due to shrinkage and fill are now angled, and angling of the defects reduces direct impact with the belt and therefore reduces the structureborne noise produced by operation of the belt and the pulley.
