Definitions

  • This invention relates to steel wire ropes, strands, steel cores and/or finished or partly finished rope, irrespective of the type of core used or whether the ropes are stranded or locked coil, and is a divisional application of application Serial No. 455,300, tiled September 10, 1954.
  • the invention is more especially, but not solely, ap-
  • the invention consists of a multi-layered, steel-wire rope or core characterized in that the king wire is faceted according to the number of wires in the first layer over it and the wires of the intermediate layer or of each successive intermediate layer are individually of polygonal section, the section of the wires of the outer layer being that of a keystone with an arcuate head, this arc being a segment of the ropes or cores curved outer circumference and adjacent wire sections being in close contact with one another over their straight edges, whereby the Wires are prevented from rolling in relation to each other.
  • These steel wire ⁇ ropes or cores are preferably made by imparting thereto a controlled degree of plastic ow with a uniform pressure all around as described and claimed in application Serial No. 455,300, of which this application is a division.
  • Fig. 1 is a cross-section of a 9/9/1 rope according to the invention with a corresponding round wire rope indicated in phantom;
  • Fig. 2 is a cross-section of a 12/6/1 rope
  • Fig. 3 is a view similar to Fig. 1 of a 12/6/1 rope with filler wires.
  • the preferred method utilizes the application of the combined resultant reactive force arising from plastic iiow under compression, coupled with predetermined elongation of the strand, while passing the rope through a suitable die capable of providing a drawing action thereon.
  • Back tension is applied to the longitudinal axis of the strand as it passes into the die, of suicient magnitude to initiate plastic ow prior to the strand entering the die, while not exceeding the limit of proportionality of the strand (that is, the point on a stress-strain curve at which the strain ceases to be proportional to the stress).
  • the originally round wires making up the rope will have been individually reformed to a geometric pattern in which the king wire has become faceted according to the number of wires laid over it, the point of contact of the next layer of overlying wires forming the base of a pentagon on each facet of the king wire, the next layer being of reversed pentagons and so on.
  • the king wire 1 is faceted with a plurality of sides 2 according to the number of Wires 3 laid over it.
  • the contact surface of the layer of Wires 3 overlying the king wire forms, in cross-section the base of a pentagon on each side or facet 2 of the king wire, and the next layer of wires 4 forms reversed pentagons, and so on, producing an interpenetrating relationship between successive layers.
  • a steel rope or core embodying this invention is materially smaller in external diameter than is a similar stranded rope or core formed of conventional round wire, Iindicated at 5, Fig. 1, where both contain the same total cross-section of metal.
  • the outer layer of wires necessarily must have a cross-sectional area considerably larger than the next successive inner layer or the outer layer will result in a relatively thin flat-sectioned wire.
  • Such a substantially uniform-sectioned multi-layered rope may have several combinations of shapes depending to a cer tain extent upon the number of wires in each layer and upon the utilization of substantially all of the cross-sectional area of the rope by the wires of uniform crosssection or by filling in some of the space in the rope by so-called filler wires.
  • the lirst type of construction is illustrated in crosssection in Fig. 2.
  • six wires 6 are arranged around a hexagonal king wire 7, and twelve wires 8 are arranged in the layer surrounding the six-wire layer.
  • the layer of wires 6 immediately adjacent to the king wire 7 are formed with pentagonal cross-sections, and the outer layer of wires 8, which contacts the outer periphery of the pentagonal wire layer, have a substantially quadrangular cross-section.
  • the outer layer of wires is formed with the outer side 9 thereof as a segment of the circumference of the rope formed on a radius corresponding to the radius of the stranded rope.
  • the Awire *ropev includes-a hexagonal king wire lll'surrounded by six/wires 11 of' substantially the same cross-sectional area as the king wire' 10, with an outer layer of'wiresVV 12 arrangedj around the intermediate layer ofwi-res 11; T his rope has substantially the same configurationY as that shown ⁇ in Fig.- 2 and, in addition, is provided with relatively small quadrangular diamondshaped filler wiresv 13 in the space between the outer edges of adjacent wires 11 in the intermediate layer of wires and theV adjacent surfaces of the outer layer' of wires ⁇ 152'.
  • these filler wires 13 also have r substantially at sides and result in two additional sides 14v on each of theintermediate layer wires 11 and one additional flat side 15 on each wire 12in the outer layer' of wires; Obviously, other arrangements off-filler wires can beutilized'l'netween any of the wires and-between any layers of wires. In this'construction the wire ropeis especially'free'of# airV gaps.
  • the outer periphery 16 of the outer wires 12 also is formedas a'segment of a circleA corresponding to the outer circumference of the rope, as in the Yother constructionsiillustratedlin Figs. 1 ⁇ and 2.
  • a multi-layered steel wire-rope comprising a centralking wire, at least one intermediate layer of wiressur rounding the kingv wire, ⁇ and ⁇ an outer layerof Wires: arranged around the intermediate layer, the kingwire beingof polygonalcross-section and faceted corresponding toy the number of wires inthe intermediate layer, each wire inthe intermediate layer being ofpentagonal cross-section pointing radially outwardly, the cross-sectionofV each wire inthe outer layer being quadrangular inshape!

  • a multi-layered steel wire rope as set forth in claim l wherein the wires in the layers of wire are individually of pentagonal cross-section and the wires in successive layers of wires alternately point in opposite directions radially in relation to the axis of the rope whereby the successive layers are in interpenetrating relationship.
