Definitions

  • the invention relates to a wire rope as a traction rope for elevators, which runs over a traction sheave with a round groove, wherein the wire rope contains a steel rope core which is surrounded by several steel outer strands.
  • the plastic coating serves to protect and preserve the rope, to cushion it and protect it from corrosion.
  • the steel outer strands with a plastic coating have, according to the drawing of the EP 0 111 797 A1 a smaller metallic cross-section compared to the steel outer strands without plastic coating. According to page 6, paragraph 1, of this publication, the "smaller" steel outer strands with a plastic coating only fill gaps and are not intended to have a load-bearing function.
  • EP 0 111 797 A1 discloses the preamble of claim 1.
  • the steel rope core is overmolded with a plastic sheath, which is surrounded by steel outer strands, which are at least partially embedded in the plastic sheath of the steel rope core.
  • This well-known wire rope is particularly suitable for elevators whose traction sheaves are designed with friction grooves that represent a round groove with undercut, a wedge shape or a wedge shape with undercut.
  • the invention is based on the object of creating a wire rope for an elevator traction sheave provided with a round groove, whereby on the one hand the friction coefficient of the rope and so that the rope performance is improved and on the other hand the service life of the rope is increased.
  • the steel outer strands provided with a plastic coating and the steel outer strands without a plastic coating can be arranged helically as the outer layer of the wire rope.
  • the steel outer strands provided with a plastic coating are load-bearing and transmit driving forces to the entire wire rope in the axial direction of the wire rope.
  • the plastic sheath preferably consists of a thermoplastic material selected from the group consisting of polypropylene, polyurethane, polyvinyl chloride, polyether-polyurethane or polyamide.
  • wire rope according to the invention according to one of claims 1 to 4 can also be used for traction sheaves which are formed with friction grooves which have a round groove with undercut, wedge shape or wedge shape with undercut.
  • the known wire rope shown contains a steel rope core 1 which is surrounded by several steel outer strands.
  • the individual steel outer strands consist of a large number of individual wires.
  • the steel rope core 1 is surrounded by, for example, twelve steel outer strands. Of these twelve steel outer strands, six steel outer strands 2a are provided with a plastic coating 4, wherein the steel outer strands 2a provided with a plastic coating 4 are arranged alternately with steel outer strands 2 without a plastic coating.
