Definitions

  • the invention relates to a wire rope as a traction cable for elevators, which runs over a traction sheave with round groove, wherein the wire rope contains a steel cable insert, which is surrounded by a plurality of steel outer strands.
  • EP 0 444 245 B1 describes a wire rope with a steel cable insert, in particular for elevators.
  • the steel cable insert is encapsulated with a plastic casing, which is surrounded by steel outer strands, which are at least partially embedded in the plastic casing of the steel cable insert.
  • This known wire rope is particularly suitable for elevators whose traction sheaves are formed with friction grooves, which represent a round groove with undercut, wedge shape or wedge shape with undercut.
  • the invention has for its object to provide a wire for a provided with a circular groove elevator pulley, on the one hand, the coefficient of friction of the rope and so that the rope performance improved and on the other hand, the life of the rope should be increased.
  • the coefficient of friction is adjustable by the proportion of plastic coated outer strands.
  • the proportion of plastic-coated steel outer strands which is required to adjust the required friction value, can be increased up to 100% by all steel outer strands are provided with a plastic sheath.
  • wire ropes with e.g. 6 to 12 steel outer strands to provide each half of these steel outer strands with a plastic sheath.
  • the achievable friction coefficient ⁇ ( ⁇ ) in traction sheaves with a round groove is between 0, 15 and 0.3.
  • the plastic outer sheathed steel outer strands and the outer steel sheaths may be plastic-sheathed
  • the steel outer strands provided with a plastic jacket, including the plastic jacket have no relative to the steel outer strands Plastic coating a radial projection of 0, 1 to 3.0 mm, preferably 0.2 to 0.8 mm.
  • the provided with a plastic sheath steel outer strands are preferably load-bearing and transferred in the axial direction of the wire driving forces on the entire wire rope.
  • the plastic coating is preferably made of a thermoplastic material which is selected from the group of polypropylene, polyurethane, polyvinyl chloride, polyether polyurethane or polyamide.
  • the plastic forming the sheath is preferably admixed with color pigments for characterizing certain coefficients of friction.
  • the provided with a plastic sheath steel outer strands preferably have over the remaining wire rope an electrically insulating effect.
  • the core of the inventive wire rope forming steel cable insert may preferably be additionally provided with a plastic sheath.
  • wire rope according to the invention according to one of claims 1 to 13 can also be used for traction sheaves, which are formed with friction grooves having a round groove with undercut, wedge shape or wedge shape with undercut.
  • Figure 1 shows in cross-section a known wire rope with one of several
  • Figure 2 shows a cross section of the wire rope according to the invention
  • the darg Congress in Figure 1 known wire rope, in particular traction cable for elevators, contains a steel cable insert 1, which is surrounded by several, in the present case eight steel outer strands 2.
  • the individual steel outer strands 2 consist of a plurality of individual wires.
  • the steel cable insert 1 is surrounded by, for example twelve steel outer strands.
  • half, ie six steel outer strands 2a are provided with a plastic jacket 4, the outer steel strands 2a provided with a plastic jacket alternating with steel outer strands 2 without plastic jacket.
  • the provided with a plastic sheath 4 steel outer strands 2a have, including the plastic sheath 4 relative to the steel outer strands 2 without plastic sheathing a radial projection a from 0.1 to 3.0 mm, preferably from 0.2 to 0.8 mm.
