Definitions

  • the invention relates to a low-rotation wire rope in full steel construction, consisting of an outer strand layer and an opposite stranded rope core.
  • Such a wire rope is a "spiral round strand rope 18 ⁇ 7, low rotation" object of DIN standard sheet 3069. These are ropes with a central fiber insert in the Rope core.
  • the rope core consists of 6 strands consisting of a wire layer and a heart wire constructed and arranged around a hemp soul.
  • DIN 3069 replaced the hemp inlay with a single-layer strand made of 1 + 6 wires be. In this case it would be the 19 ⁇ 7 wire rope construction.
  • wire ropes have a relatively small metallic cross section and therefore one correspondingly low breaking strength. Furthermore, they do not have an optimal circulation the outer strand layer on the rope core.
  • DE-C-240 777 which is a wire rope with a steel core Suspension cable for cable cars, i.e. standing goods.
  • DE-OS 23 25 931 shows a round strand wire rope in a low-rotation or rotation-free design, in which the outer strands of the core are parallel lay strands, whose metallic cross section is at least 50% larger than the metallic cross section the outer strands of the rope.
  • a wire rope as contained in Fig. 1 of DE-C-240 777 is and it is because of the large diameter the core outer strands, which form the main part of the metallic cross-section in the side! identify the need to design them in parallel laydown.
  • these form an expensive design basis for the rope core design.
  • the support of the outer strand layer on the rope core can be improved will.
  • EP-A-0 444 245 relates to a solid steel wire rope with a steel strand insert, in particular for lifts.
  • the steel strand insert and the outer strand layer have the same Direction of impact.
  • no more than 10 outer strands can be arranged, because then the outer wires would become too thin, which is caused by the friction drive on the elevator rope leads to wire breaks too early and leads to premature rope laying.
  • the invention has for its object to provide a low-rotation wire rope, the with a simple structure and therefore inexpensive manufacture, a long service life has high breaking strength and is in operation even when deflected over the on this Hoist sector in use Diameter of the deflection elements with special consideration of the mandatory Multi-layer winding of the rope on the drum has proven itself.
  • the rope diameter is the same Larger metallic cross section compared to comparable designs after the State of the art achieved. This leads to a significant increase in breaking strength.
  • a higher breaking strength means for the designer of hoists with a given one Load capacity that a greater rope safety is given or a thinner wire rope can be used.
  • a particular advantage of the wire rope according to the invention lies in the essential better support of the rope outer strand layer on the rope core, the much more cylindrical-round is less rotational and more rotation-free than the previous insoles Styles. This results in significantly lower specific contact pressures under load in the zone known as critical between the underside of the outer rope strand and the periphery of the rope core.
  • This and the design of the rope core as a parallel lay strand ensure that the rope structure is protected, which is to be regarded as the basis for a further increase in rope performance.
  • the wire rope according to the invention is also with a single central heart strand as the rope core considerably less twist than a rope with the same number of outer strands that over a classic central insert are arranged.
  • the wire rope according to the invention has high dimensional stability has, which ensures a uniform rope diameter, which is special is important for rope drums in horizontal jib cranes.
