Abstract
A belt and sprocket system comprising a tensile cord disposed within a belt body, at least two teeth projecting from the belt body, the belt comprising a pitch length measured between the at least two teeth on the belt, one of the at least two teeth having a tooth tip and a profile comprising a first radius and a second radius and a third radius disposed between a first linear segment and a second linear segment, the sprocket having a groove for receiving one of the at least two teeth, the groove profile comprising a first radius and a second radius and the third radius and a fourth radius, each of which is connected in series to the others and each of which is unequal in length to the other radii, the tooth having a width that is approximately 35% of a pitch length at 90% of a tooth height so as to result in an interference fit between the one of at least two teeth and groove at 90% of the tooth height; and a volume between the tooth tip and the groove.
