ABSTRACT:
A multiribbed power transmission belt having an inner portion of the compression section thereof defined by arcuate side surfaces converging inwardly. In one form, the side surfaces are circular. The outer portion of the compression section is defined by planar side surfaces converging inwardly. In one embodiment, the outer portion side surfaces are tangent to the inner portion arcuate surfaces and, in another form, the outer portion planar side surfaces intersect the arcuate side surfaces of the inner portion of the compression section. The distal tip of the ribs, in one form, is circular concentric with the side surfaces of the inner portion. In an alternative disclosed form, the tip surface is planar transversely to the rib.
