Definitions

  • the invention relates to a flat belt-like support and propellant with at least two tension members made of synthetic fibers, wherein the tension members extend at a distance from each other axially parallel to the longitudinal axis of the support and propellant and are embedded in a jacket according to the definition of the independent claim.
  • WO 2004/035913 A1 is a flat belt-like support and propellant known with tension members made of synthetic fibers, being provided as a tension carrier at least two stranded strands, which have stranded synthetic fiber yarns and are designed to absorb power in the longitudinal direction.
  • the strands are spaced along the longitudinal direction of the support and propellant and embedded in a common jacket.
  • At least one of the strands has an electrically conductive indicator yarn which is stranded together with the synthetic fiber yarns of the strand, the indicator yarn being arranged outside the center of the yarn bundle.
  • the indicator yarn has an elongation at break which is less than the breaking elongation of individual synthetic fiber yarns of the strand.
  • the indicator yarn may be contacted to allow electrical monitoring of its integrity.
  • the synthetic fiber rope has become known for driving by a traction sheave.
  • the synthetic fiber rope is constructed as a twin rope of two stranded in opposite directions of rotation ropes, which are rotationally fixed and fixed in their parallel, spaced position to each other by a common cable sheath.
  • the present invention integrally formed on both ropes cable sheath acts as a torque bridge, the longitudinal rope of the twin rope, due to the rope structure resulting, oppositely oriented torques of the ropes canceled each other and thus over the total cross section of the twin rope torque compensation between the sum of all right and left-handed Litzenanteile creates.
  • the twin rope behaves during the run over a pulley rotation.
  • the invention aims to remedy this situation.
  • the invention as characterized in claim 1 solves the problem of providing a support and propellant with smaller bending stresses in the tension members.
  • the pulley-side strand half When bending a strand around the traction sheave or around the deflection pulley, the pulley-side strand half is subjected to compressive stresses and the free strand half to tensile stresses. Between the compression / tension-stressed strand halves runs the neutral pressure neither tensile nor tensile stressed. Too high compressive / tensile stresses in the strand lead to premature failure of the strand.
  • Each tension member consists of several layers of strands, wherein the strands forming the strand layer are stranded. (Helical rounding of strands of a strand layer around the underlying strand layer). Each strand consists of several yarn layers, the yarns forming the yarn layer being stranded. (Helical twisting of yarn layer yarns about the underlying yarn layer). Each yarn consists of several, unidirectional or unsewn synthetic fibers also called filaments. Each yarn is impregnated in a plastic bath. The plastic wrapping a yarn or strand is also called matrix or matrix material. After stranding the yarns into a strand, the plastic of the yarns is heat-treated homogenized. The strand then consists of stranded yarns completely embedded in the plastic.
  • a strand consists of stranded yarns, which in turn consist of unstretched or unidirectional synthetic fibers, a yarn consisting for example of 1000 synthetic fibers, also called filaments.
  • the stranding direction of the yarns in the strands is provided so that the individual fiber is oriented in the pulling direction of the rope or in the cable longitudinal axis.
  • Each yarn is impregnated in a plastic bath.
  • the plastic surrounding a yarn or strand is also called matrix or matrix material.
  • the fibers are joined together by the matrix but have no direct contact with each other.
  • the matrix completely encloses or embeds the fibers and protects the fibers from abrasion and wear. Due to the rope mechanics, shifts occur between the individual fibers in the strands. These shifts are not converted by a relative movement between the filaments, but by a reversible stretching of the matrix.
  • the stranding of yarns into a strand is referred to as the first stranding step.
  • the stranding of strands to a tension member or a rope is referred to as a second stranding stage.
  • the tensile carrier may be composed of chemical fibers such as aramid fibers, Vectran fibers, polyethylene fibers, polyester fibers, etc.
  • each strand consists of yarn layer stranded yarns.
  • the relative movements from strand to strand leading to wear of the strands can be kept small. This ensures a long service life of the tension members.
  • thinner strands have a higher tensile strength than strands of large diameter due to the size factor, which advantageously results in a higher breaking load.
  • the support and propellant for applications in elevator construction in particular as a support and propellant for the elevator car and the counterweight, for example, the geometry of a flat belt or a ribbed belt or the geometry of a toothed belt.
  • the tension members are arranged side by side, the tension members are alternately struck or stranded in the S and Z directions and are relatively close together.
  • at least two, preferably between 4 and 12 tension members are provided.
  • these tension members are constructed as a fiber composite, wherein the plastic surrounding the strand (matrix material) is preferably made of polyurethane and the fibers which absorb the tensile forces are preferably made of aramid.
  • the Matrix material mixed between 1% and 10% Teflon.
  • Other additives such as wax or Teflon powder are also useful.
  • the jacket can have a Shore hardness of 72A to 95A and the matrix can have a Shore hardness of 80A to 98A.
  • Shore hardness 85A for the sheath and 95A which corresponds to a Shore hardness 54D
  • the carriers are alternately beaten or stranded in the S direction and in the Z direction.
  • the torque of one tension member rotates in the opposite direction as the torque of the other tension member, so that the torques cancel each other out.
  • the torque-neutral support and propellant does not twist by the introduction of a tensile force. It is also possible for two or three stranded in the S direction and two or three stranded in the Z direction tensile carriers are arranged side by side.
  • the decisive factor is that the stranding in the S and Z directions is torque-neutral compared to the longitudinal axis running in the center of the support and propellant.
  • the lay length SL is also related to the modulus of elasticity of synthetic fibers. With an increasing modulus of elasticity, a shorter lay length can be selected with a constant fiber cross-sectional area without the spring stiffness of the suspension element being reduced.
  • the inventive support and propellant is flat belt-like and consists of at least two tension members made of synthetic fibers, wherein the tension members with a distance from each other axially parallel to the longitudinal axis of the support and Propellant and are embedded in a jacket, and each tension member consists of several strands, each strand is formed of several stranded yarns.
