Definitions

  • the present invention provides a Wire rope differing substantially from, but which can have some features in common with, the wire rope structures disclosed in my copending applications, Serial No. 70,160, led November 18, 1960, and Serial No. 192,156, tiled May 3, 1962, which applications were issued as United States Patent Nos. 3,131,530 and 3,154,910 on May 5, 1964, and November 3, 1964, respectively.
  • the invention relates to wire ropes wherein synthetic plastic material is used although from different considerations than those obtaining hitherto. It proceeds from the fact that the chief reason for the destruction of the rope structure resides in the high pressures per unit of surface area which occur not only between the wires or strands of the rope but also between the outer elements of moved ropes and their guide pulleys.
  • the round cross-section of the ropes and wires leads unavoidably to the contact zones between adjoining parts being punctiform or at the most linear in form, and this leads to abrasion, notching, ilattening, etc.
  • the invention proposes working into the natural gaps between the outer elements of the rope synthetic plastic material iillings which, preferably without any adhesive connection to the said elements, are bounded by a cylindrical generated surface corresponding to the rope diameter.
  • plastic fillings are made to engage beyond the centre circle between the outer elements in the manner already described, they can readily be extended inwardly so far, without changing the normal rope, that they extend through between the outer elements as far as the rope elements which follow the said outer elements, and if necessary partly surround the said inner elements.
  • the synthetic plastic material is to terminate externally at a cylindrical generated surface which corresponds to the diameter of the rope and which, accordingly, adjoins tangentially the outer elements of the rope.
  • the illustrated rope comprises a core strand 1 (1+6 wires), and inner layer 2 of strands (strands of 1-l-6 wires) and an outer layer 3 of strands (7 parallel lay strands comprising core wire and 12 inner and 12 outer wires).
  • the illings of hard tough plastic material may extend inwardly into the rope so far that they engage the outermost wires ⁇ of the strands of the inner layer 2, but not so far as to lie radially beneath the outer strands.
  • Eachprlling thus has a cross-section of dovetailed shape with'the inner portion of its body wedged, inside the circle 11, between confronting inner side portions of adjacent strands of the outer layer 3 and between those portions and the outermost wires of a strand of the inner layer 2.
  • the rope is not exactly circular, it may be that for example the synthetic plastic material will at rst slightly cover one or other outer strand, for example in the form of a thin skinl of plastic material, the ropeadjusts itself in such a manner during use that the peripheral line of the rope bounds both the synthetic plastic material and the outer strands.
  • a stranded wire rope comprising inner wire rope elements overlaid by a circumferential .series ofV outer ⁇ helical Wire strands spacedapart inparallel lay, and 'lillings of a hard tough synthetic plastic material extending radially in the spaces between said outer strands and holding said strands laterally separated one from another, said llings terminating at their outer side substantially at the peripheral outline of said series, and being separate at their inner sides and there terminating away from the radially innermost surfaces of said strands, and being suiciently hard andtough that they keep said strands from contacting one another laterally and limit the radial pressure of said strands upon saidinner elements when the rope is under strain.
  • a stranded wire rope according to claim l said fillings having no adhesive connection to said strands spaced apart in parallel lay.
  • a stranded wire rope comprising inner wirerope elements overlaid by a circumferential series ofV outer helical wire strands spaced apart in parallel lay, and iillings of a polyamide resin extending radially in the spaces;- between said outer strands and holdingrsaid strands laterally separated one from another, said fillings termin-ating at their outer side substantially at the peripheral outline of said series, and being separate at their inner sides and there terminating away from the radially innermost surfaces of said strands, and being suiciently hard and tough that they keep said strands from contacting one another laterally and limit the radial pressure of said strands upon said inner elements when the ropeis under strain;
  • a stranded wire rope comprising inner wire ropeY elements overlaid by a circumferential series of outerv I of outer helical wire strands spaced apart in parallel lay,
  • a stranded wire rope comprising inner wire rope elements overlaid by a circumferential series of outer helical wire strands wound thereupon in parallel lay with small ⁇ spacings left between said strands, and llings of a hard tough-synthetic plastic material, each of substantially dovetail cross-section, molded into said spacings and holding said strands laterally/,separated one from another, said llings terminating at their outer side substantially at the peripheral outline of said series and extending inwardly in wedging engagement with confronting side portions of'said strands insidey the center line of said series, and being separate at their inner sides and there terminating away from the radially innermost surfaces of said strands, and being suciently hard and tough that they keep said strands from contacting one another laterally and limit-the radial vpressure of Vsaid outer strands upon said inner elements when theV rope is under strain, the outermost surfaces of said fillings deining a substantially cylindrical rope surface substantially tangent
