  • the third strands 22 are disposed further inward than the outer peripheral surface of the inner layer 25. In other words, the third strands 22 are covered by the inner layer 25 so as not to be exposed outside the inner layer 25.
  • High-friction resin materials such as polyurethane resins, for example, can be used for the materials for the inner layer 25 and the outer layer 26. It is preferable for the high-friction resins to have a coefficient of friction greater than or equal to 0.2 to enable sufficient transfer efficiency of driving force to be ensured.

  • the hardness of the outer layer 26 is greater than the hardness of the inner layer 25.
  • the color of the inner layer 25 is also different than the color of the outer layer 26.
  • the third strand layer coating body 23 is constituted by flame-retarded resins.
  • a polyurethane resin was used as the material for the second strand layer coating body 12, but in Embodiment 3, because the second strand layer coating body 12 is not the outermost layer, a polyethylene resin, for example, can be used for the material for the second strand layer coating body 12. Specifically, it is desirable that the material for the second strand layer coating body 12 be a similar material to that of the first strand coating bodies 7, or a resin having a low melting temperature.
  • a diameter of an inner layer rope constituted by the core rope 1 and the second strand layer 11 is set so as to be less than or equal to 1/27 of a diameter of the sheaves with which it is used, in other words, the sheaves around which this elevator main rope is wound.

  • first strand coating bodies 7, a second strand layer coating body 12, and auxiliary strand coating bodies 15 are used, the core wires 5 and the first wires 6, the first wires 6 and the second wires 9, the second wires 9 and the auxiliary strand wires 14, the auxiliary strand wires 14 and the third wires 24, and the second wires 9 and the third wires 24 are respectively prevented from contacting each other directly, enabling deterioration due to abrasion to be prevented and bending stresses to be alleviated by a buffer action, thereby enabling extension of the service life of the elevator rope.
  • the third strand layer coating body 23 is disposed on a portion contacting the sheaves, the third strands 22 can be prevented from being abraded by direct contact with the sheaves. Furthermore, bending stresses arising due to the third wires 24 being crushed by the sheaves can also be alleviated, enabling extension of the service life of the elevator rope and also enabling reductions in the diameters of the sheaves.
  • the third strand layer coating body 23 is disposed on an outermost periphery, abrasion of the sheaves can also be prevented, enabling a degree of freedom in selecting materials for the third wires 24 and the sheaves to be improved. Consequently, overall strength can be increased further and the sheaves can be constructed inexpensively.
  • the third strand layer coating body 23, which comes into contact with the drive sheave, is constituted by high-friction resin materials, sufficient transfer efficiency of the driving force can be ensured even if the diameter of the drive sheave is reduced.
  • Soft or hard polyurethane resins can also be selected freely for the third strand layer coating body 23, but in order to ensure abrasion resistance performance against minute slippage on the surface of the sheaves, it is preferable to use hard polyurethane resins having a hardness of 90 or more. In addition, in order to prevent hydrolysis from occurring in the service environment, it is also desirable that the resins be ether-based rather than ester-based.
  • first strand coating bodies 7, the second strand layer coating body 12, and the auxiliary strand coating bodies 15 a material that slides freely and easily when the elevator rope is bent at the sheaves. Furthermore, the first strand coating bodies 7, the second strand layer coating body 12, and the auxiliary strand coating bodies 15 require a hardness that can resist being crushed between the wires. Hard, low-friction polyethylene materials are suitable as these materials.
  • the first strand coating bodies 7, the second strand layer coating body 12, and the auxiliary strand coating bodies 15 do not require such a large coefficient of friction as the third strand layer coating body 23, and since bending by the sheaves is not as great, they do not necessarily require superior elongation characteristics. Consequently, resins such as nylon, silicon, polypropylene, or polyvinyl chloride, etc., for example, may also be used as the materials for the first strand coating bodies 7, the second strand layer coating body 12, and the auxiliary strand coating bodies 15.
  • the third strands 22 have a simple seven-wire construction including a central wire 24a and six outer peripheral wires 24b, the diameter of the elevator rope can be reduced and disarray is less likely to occur, enabling coating of the third strand layer coating body 23 to be performed easily.
  • rotational torque in a direction in which the lay returns may occur in interior portions due to repetitive bending by the sheaves and tension due to loads over time, and there is a risk that the load burden balance of each of the layers may collapse, reducing breaking strength and service life.
  • the rotational torque in the interior portions can be balanced, enabling the overall lay-returning torque of the rope to be reduced.
  • Figure 5 is a cross section showing the elevator rope in Figure 3 wound around a sheave
  • Figure 6 is a cross section showing an abraded state of an outer peripheral portion of the elevator rope in Figure 5. Abrasion of the outer peripheral portion is caused by sustained operation or by abnormalities. In the state in Figure 6, there is a risk that traction capacity will decrease since the state of contact of the rope with a rope groove 30 is looser than the state in Figure 5.
  • Traction capacity e K2 ⁇
  • K 2 is approximately 1.2, but K 2 decreases with the abrasion of the outer peripheral portion of the rope.
  • K 2 hypothetically decreases to 1.0, since the contact angle ⁇ is constant, traction capacity cannot be ensured unless the coefficient of friction ⁇ is made twenty percent (20%) larger.
  • Embodiment 3 since the coefficient of friction of the inner layer 25 is greater than the coefficient of friction of the outer layer 26, reductions in traction capacity can be suppressed even if the outer layer 26 is abraded and the inner layer 25 is exposed. In particular, because the coefficient of friction of the inner layer 25 is greater than the coefficient of friction of the outer layer26bytwentypercent (20%) ormore, sufficient traction capacity can be maintained even if the inner layer 25 is exposed.
  • the coefficient of friction of the inner layer 25 can easily be made greater than the coefficient of friction of the outer layer 26 by setting the hardness of the outer layer 26 so as to be greater than the hardness of the inner layer 25.
  • the third strand layer coating body 23 is constituted by flame-retarded resins, if a fire occurs in the building, even if flames somehow get inside the hoistway, the fire can be prevented from spreading via the elevator rope. Spreading of the fire via the elevator rope can also be prevented if the third strand layer coating body 23 is constituted by flame-retardant materials.
  • Figure 7 is a cross section of an elevator rope according to Embodiment 4 of the present invention.
  • first strands 4 are each constituted by a plurality of first wires 6 without a first strand coating body.
  • the first strands 4 are in direct contact with core wires 5 and second wires 9.
  • a cross section of at least some of the core wires 5 is modified by compressing a core strand 3 from an outer periphery.
  • a cross section of the first wires 6 is also modified by compressing the first strands 4 from an outer periphery.
  • a cross section of at least some of the second wires 9 is modified by compressing second strands 8 from an outer periphery. The rest of the construction is similar to that of Embodiment 1.
  • the modified wires 5, 6, and 9 come into contact with each other at surfaces or lines rather than points, thus enabling the wire packing density to be increased. Furthermore, contact pressure among the core wires 5, among the first wires 6, and among the second wires 9 is reduced, suppressing abrasion of the wires 5, 6, and 9. In addition, disarray of the core strand 3, the first strands 4, and the second strands 8 is prevented, enabling extension of service life.
