Abstract
Official abstract text for this publication.
A wire rope includes a strand that is formed by winding a plurality of metal wires. The strand includes a core wire and side wires. Each of the side wires is arranged on an outer periphery of the core wire. In a transverse section of the strand, each of the side wires includes end portions positioned at opposite ends in a circumferential direction of the core wire. Each of the end portions includes a contact portion in contact with an end portion of an adjacent side wire, and a non-contact portion not in contact with the adjacent side wire. A Vickers hardness of the contact portion is higher by 1% or more than a Vickers hardness of the non-contact portion. A surface roughness Ra of an outer peripheral surface of each of the side wires is 0.10 μm or less.
First claim
Opening claim text (preview).
What is claimed is: 1 . A wire rope, comprising: a strand that is formed by winding a plurality of metal wires, wherein: the strand includes a core wire arranged in a center of the plurality of metal wires, and side wires that make up a remainder of the plurality of metal wires, each of the side wires being arranged on an outer periphery of the core wire, in a transverse section of the strand, each of the side wires includes end portions positioned at opposite ends in a circumferential direction of the core wire, each of the end portions includes a contact portion in contact with an end portion of an adjacent side wire, and a non-contact portion not in contact with the adjacent side wire, a Vickers hardness of the contact portion is higher by 1% or more than a Vickers hardness of the non-contact portion, a surface roughness Ra of an outer peripheral surface of each of the side wires is 0.10 μm or less, the strand is obtained by die-drawing a twisted wire including a plurality of circular-cross-section metal wires, and a cross-sectional width of the strand is 57.2% to 85.7%, or 42.9% to 71.4%, of a diameter of the twisted wire before the die-drawing. 2 . The wire rope according to claim 1 , wherein at each of the end portions, the Vickers hardness of the contact portion is higher by 3% or more than the Vickers hardness of the non-contact portion. 3 . The wire rope according to claim 1 , further comprising a plurality of strands including the strand, wherein the wire rope is formed by winding the plurality of the strands.
