Power transmission belt

摘要

A V-belt construction wherein a belt body defining an inner compression rubber portion and an outer compression rubber portion with tensile cords extending longitudinally therethrough is provided with a plurality of transversely extending reinforcing staple fibers distributed in the outer compression rubber portion such that the tensile cords are embedded within the distribution of the staple fibers. V-belts of the invention are provided both in raw edge and fabric-covered form. The rubber in which the tensile cords are embedded preferably has a hardness in the range of approximately 70 DEG to 90 DEG . Different distributions of the transverse staple fibers are disclosed.
