Abstract:
The present invention relates to a wire for wrapping which is wound spirally on the outer circumference of a main cable in which a plurality of metal wires are compactly arranged in parallel, wherein the wire for wrapping is a zinc-aluminum-alloy-coated shaped steel wire with superior corrosion resistance which has an S-shaped cross section coated with a zinc-aluminum alloy and has a thickness of coating layer of at least 20µm at any part of the outer circumference of the S-shaped cross section. A method of producing a zinc-aluminum-alloy-coated shaped steel wire according to the present invention comprises the steps of: primarily rolling a material wire rod; performing stress-relief heat treatment for the primarily rolled wire at a temperature of 300-500°C; coating the heat-treated primarily rolled wire with a zinc-aluminum alloy; and secondarily rolling the coated primarily rolled wire at a rolling quantity of 5-40% to obtain the shaped steel wire of the S-shaped cross section.
Abstract:
A resin-coated high-tension flat steel wire includes a high-tension flat steel wire and a fiber-reinforced polyamide resin coated layer. A shape of the high-tension flat steel wire when viewed from a section perpendicular to a longitudinal direction thereof is a rectangular shape including curved portions at four comers thereof. When, among four straight lines that form the rectangular section, the ranges from both end points of the straight lines that form long sides to one fourth of the length of the straight lines are respectively defined as one-fourth segments, a shape of the fiber-reinforced polyamide resin coated layer in the rectangular section includes a mountain shape having an apex within each of the one-fourth segments, and includes a minimum point, where the thickness of the fiber-reinforced polyamide resin coated layer is the minimum, between the apex and both the ends within each of the one-fourth segments.
Abstract:
A strand (20) for a cable bolt (14) comprises a plurality of metallic elongated members (22, 24) twisted together. At least one of the elongated members has a corrosion resistant coating (54) and surface deformation, so as to improve the bodig efficiency and the anchorage of the strand.
Abstract:
A bicycle control cable (12) is provided with a central wire (22) and a radial protrusion (24). The central wire (22) includes at least one metallic strand (34) defining a radially outermost surface (22a) of the central wire (22). The radial protrusion (24) extends along the radially outermost surface (22a) in a direction intersecting with a center longitudinal axis of the central wire. The radial protrusion (24) reduces a sliding resistance of the central wire (22). The central wire (22) and the radial protrusion (24) are configured and arranged to slidably move in an axial direction with respect to the center longitudinal axis of the central wire within an outer case (26) to operate a bicycle component.
Abstract:
An object of the present invention is to improve durability of a bead portion of a tire by optimizing a sectional shape and arrangement of a bead wire(s). The pneumatic tire comprises: a pair of bead portions having bead cores embedded therein, each bead core being constituted of plural bead wires extending in the tire circumferential direction; a pair of side wall portions extending from the bead portions on the outer side in the tire radial direction; a tread portion extending over the respective sidewall portions; and a carcass extending in a toroidal shape across the aforementioned portions and having respective end portions being turned up around the bead cores, wherein the bead wires each have complementary shape portions in a section in the tire widthwise direction, by which shape portions adjacent bead wires are complementarily engageable with each other.
Abstract:
A reinforcing structure designed for handling compression stress states when the structure is molded into a composite. The structure, specifically a wrapped cord (10, 20) with metallic filaments (12) contained therein, is suitable for both compression and tension load forces. The reinforcing structure has a core (14) comprising a plurality of essentially straight, nested filaments (12) arranged in parallel, the filaments (12) forming a line of contact with adjacent filaments (12) that extends along the length of the filaments (12). Wrapped about the core (14) is at least one helically wound wire (16).
