Abstract
Abstract A V-belt for transmitting power has one or more flexible internal steel cord belts incorporated therein together with conventional textile reinforcing means. The steel cord belt reinforcement is in a plane parallel to the inner and outer parallel faces of the V-belt. The provision of the steel cord belt reinforcement minimizes belt cracking and materially increases belt tensile strength and stability without substantially lessening flexibility of the V-belt.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
103 words
A power transmission belt comprising a belt body formed of elastomer and having inner and outer parallel faces, and at least one flexible steel cord belt reinforcement for said transmission belt bonded integrally therewith and extending from side-to-side thereof and continuously longitudinally of the transmission belt, said steel cord belt comprising a relatively this assemblage composed of two adjacent layers of flexible steel wires, each layer of wires being arranged in closely spaced side -by-side relationship and on an opposite bias relative to the longitudinal axis of the transmission belt, the plane of said reinforcement being parallel to said inner and outer faces.
Claim 2
Dependent Claim
103 words
A power transmission belt comprising a belt body formed of elastomer and having inner and outer parallel faces, and at least one flexible steel cord belt reinforcement for said transmission belt bonded integrally therewith and extending from side-to-side thereof and continuously longitudinally of the transmission belt, said steel cord belt comprising a relatively this assemblage composed of two adjacent layers of flexible steel wires, each layer of wires being arranged in closely spaced side -by-side relationship and on an opposite bias relative to the longitudinal axis of the transmission belt, the plane of said reinforcement being parallel to said inner and outer faces.
Claim 3
Dependent Claim
39 words
A power transmission belt according to claim 1, wherein said elastomer belt body comprises a V-belt body and said flexible steel cord belt reinforcement is arranged internally of said transmission belt and between said inner and outer parallel faces.
Claim 4
Dependent Claim
25 words
A power transmission belt according to claim 1, wherein said flexible steel cord belt is a thin sngle layer belt of interwoven steel wire strands.
Claim 5
Dependent Claim
31 words
A power transmission belt according to claim 3, and said flexible steel cord belt comprising a thin highly flexible single layer belt near the radial center of said elastomer belt body.
Claim 6
Dependent Claim
42 words
A power transmission belt according to claim 4, and certain of said steel cord belts disposed relatively near the inner and outer circumferential surfaces of the belt and other steel cord belts disposed relatively near the radial center of the belt body.
