Abstract:
An annular metal cord includes an annular core portion and an outer layer portion. The annular core portion is formed by connecting together both ends of a first strand material which is made up of six twisted first metal filaments. The outer layer portion is formed by winding spirally a second strand material which is made up of six twisted second metal filaments around the annular core portion. The second strand material is wound at a predetermined winding angle relative to a center axis of the annular core portion, and a winding initiating end portion and a winding terminating end portion are connected together. As a result, the breaking strength of the annular metal cord can be made large, and the production thereof can be facilitated.
Abstract:
A bead cord is described including an annular core and a side wire. The side wire is helically wound around the annular core. Further, the annular core is made of a strand wire. The strand wire includes a plurality of twisted core wires. The plurality of core wires may have substantially the same diameter.
Abstract:
A method for manufacturing a bead cord wire includes the steps of subjecting a steel wire to a descaling treatment, subjecting the descaling-treated steel wire to a chemical conversion coating treatment through electrolysis so as to form a phosphate coating on a surface of the steel wire, and subjecting the chemical-conversion-coating-treated steel wire to drawing so as to produce a bead cord wire. In producing the bead cord wire, the drawing is conducted in such a way that the phosphate coating remains on the surface of the bead cord wire.
Abstract:
A light weight alloy bead core 30 is described having an inner core 33 made of an alloy of a light weight metal wire 34 with an outer sheath 35 of steel wires 36. The bead core 30 is particularly suited for heavy-duty service conditions in tires 100 for aircraft, off-road equipment, and commercial trucks.
Abstract:
An extruded polymeric rod is elongated in the solid state by being drawn through a forming device to produce a solid polymeric core having an orientated structure which comprises elongated crystals orientated in the axial direction of the core. The core may also comprise crystals orientated in respective radial directions. The single rod may be replaced by a bundle of rods.
Abstract:
Small diameter wire rope having a relatively ductile and preferably solid core is found to be strong yet better resists shearing forces than similar rope having a high strength core strand.
Abstract:
A wire strand is made by helically winding a number of layers of steel wire around a steel king wire. The wires in such layers are made from a first steel grade while the king wire is made from a second steel grade. In addition, the outermost layer of wire in the strand may be made from a third steel grade. A wire rope is formed by helically winding a number of such wire strands around a wire core.
Abstract:
A steel wire rope is presented for use in elevators and lifting applications. The steel wire rope contains a core surrounded by multiple strands. The outer filaments of the core and the outer filaments of the strands are likely to contact one another during use. The outer steel filaments of the core have an average Vickers hardness that is at least 50 Vickers hardness numbers lower than that of the outer filaments of the strands. As the hardness of the outer filaments of the core is substantially lower than that of the outer filaments of the strands, those softer filaments will preferentially abrade away during use. In this way the core is sacrificed while preserving the integrity of the outer filaments of the strands. The use of this ‘sacrificial core’ results in a higher residual breaking load after use.
Abstract:
A tow cable for a decoy on a fast jet aircraft is described. The tow cable has a composite structure with a high friction fibre outer containment braiding, and low friction fibre internal strength members. Additional to these internal fibres may be electrical conductors and optical fibres. The whole composite providing a tow cable with high towing endurance and reliable in-flight performance, for flight profiles including high performance manoeuvres and in-flight refuelling.
Abstract:
An object of the invention is to provide a high strength and light hybrid rope. At the center of the hybrid rope 1, there is arranged a high strength synthetic fiber rope 3 formed by braiding multiple high strength synthetic fiber bundles 30 each composed of multiple high strength synthetic fiber filaments 31. Given that the pitch of braid of the high strength synthetic fiber bundles 30 is represented by “L” and the diameter of the high strength synthetic fiber rope 3 is represented by “d”, the pitch of braid “L” and the diameter “d” are adjusted such that the value L/d is equal to or higher than 6.7.
