  • a lubricant e.g., lubricating oil or the like
  • the core rope 2 and the individual outer layer strands 3 are impregnated into the core rope 2 and the individual outer layer strands 3. That is, the lubricant is filled into minute gaps in the core rope 2 and in each of the outer layer strands 3.
  • the cross sectional structure of each of the core strand 4, the inner layer strands 6 and the outer layer strands 3 is made to be of a Seale type.
  • the number of the outer layer strands 3 can be increased to more than twelve in order to further suppress the wear of the outer layer strands 3, but if the number of the outer layer strands 3 is increased to more than twelve, the outer layer strands 3 will be made smaller in diameter. As a result, the area occupied by the outer layer strands 3 with respect to the core rope 2 becomes smaller. As a result, the ratio of the strength bearing capacity of the individual outer layer strands 3 with respect to the elevator rope 1 (the strength bearing ratio of the outer layer strands 3) becomes less than the ratio of the strength bearing capacity of the core rope 2 with respect to the elevator rope 1 (the strength bearing ratio of the core rope 2).
  • a determination as to whether the elevator rope 1 needs to be replaced is made by regular check so as to avoid trouble due to the aging degradation or deterioration of the elevator rope 1.
  • Such a determination of the need for replacing the elevator rope 1 is carried out by checking (observing) the state of the outer layer strands 3 (e.g., break, the degree of wear, or the like of the elemental wires 14 through 16). That is, whether the elevator rope 1 needs to be replaced is determined not by the state of the core rope 2 but rather by the state of the outer layer strands 3.
  • the elevator rope 1 it is set such that the strength bearing ratio of the outer layer strands 3 becomes larger than the strength bearing ratio of the core rope 2, by making the number of the outer layer strands 3 to be 12.
  • the total value of the breaking forces or loads of the individual elemental wires 8 through 13, which constitute the core strand 4 and the individual inner layer strands 6, (the collective breaking load of the core rope 2), is set to be equal to or less than 0.6 times the total value of the breaking forces or loads of all the elemental wires 14 through 16, which constitute the individual outer layer strands 3, (the collective breaking load of all the outer layer strands 3).
  • the collective breaking load of the core rope 2 is set to be 0.6 times the collective breaking load of all the outer layer strands 3, assuming that the collective breaking load of all the outer layer strands 3 is A, the collective breaking load of the core rope 2 is 0.6 x A, and an (initial) breaking load P1 of the elevator rope 1 immediately after the production thereof is represented by expression (1) below.
  • the six inner layer strands 6 are arranged on the outer peripheral portion of the inner layer covering member 5 with which the core strand 4 is covered, and the twelve outer layer strands 3 are arranged on the outer peripheral portion of the outer layer covering member 7 with which the core strand 4, the inner layer covering member 5, and the individual inner layer strands 6 are covered in a collective manner.
  • the individual outer diameters of the core strand 4, the inner layer strands 6 and the outer layer strands 3 can be made close to uniform, and the diameters of the individual elemental wires 8 through 16 can also be made close to uniform.
  • the diameter of the sheave, around which the elevator rope 1 is adapted to be wrapped can be made smaller, thus making it possible to reduce the size of the elevator apparatus as a whole.
  • Fig. 3 is a cross sectional view that shows a state of the elevator rope 1 of Fig. 1 being wrapped around a sheave.
  • a sheave 21 has a groove 22 formed on an outer peripheral portion thereof.
  • the cross sectional shape of the groove 22 is made semicircular. The elevator rope 1 is wrapped around the sheave 21 while being inserted into the groove 22.
  • the outer layer strands 3 are placed in contact with the inner surface of the groove 22. Since the number of the outer layer strands 3 is made to be twelve which is more than that, i.e., six, in the conventional cases, the number of those outer layer strands 3 which are in contact with the inner surface of the groove 22 becomes more, so the area of the portion of the elevator rope 1 being in contact with the sheave 21 can be increased. As a result, the contact pressure of the elevator rope 1 on the sheave 21 can be reduced, thus making it possible to suppress the wear of the elevator rope 1. Accordingly, it is also possible to further increase the life span of the elevator rope 1.
  • the outer layer strands 3 can be composed of the elemental wires 14 through 16 which are thinner than those used in the conventional cases, whereby the fatigue resistance of the elevator rope 1 can be improved.
  • the diameter of the sheave 21 which should be conventionally 40 times or more the diameter of the elevator rope, can be decreased up to about 30 times the diameter of the elevator rope 1.
  • the individual inner layer strands 6 are arranged along the outer peripheral portion of the inner layer covering member 5 at intervals from one another, and the individual outer layer strands 3 are arranged along the outer peripheral portion of the outer layer covering member 7 at intervals from one another.
  • the core strand 4 it is possible to prevent the core strand 4, the individual inner layer strands 6 and the individual outer layer strands 3 from being in contact with one another.
  • the respective wear of the core strand 4, the individual inner layer strands 6 and the individual outer layer strands 3 can be suppressed, thus making it possible to further increase the life span of the elevator rope 1.
  • the bending stress of the entire elevator rope 1 can be alleviated by the cushioning action of the inner layer covering member 5 and the outer layer covering member 7.
  • each of the core strand 4, the inner layer strands 6 and the outer layer strands 3 is formed by twisting a plurality of elemental wires with one another in a parallel twist. Accordingly, the state of contact of the individual elemental wires can be made into a line to line contact. As a result, the contact pressure of each elemental wire can be reduced, and the wear of each elemental wire can be suppressed. Thus, it is also possible to further increase the life span of the elevator rope 1. In addition, gaps between adjacent ones of the individual elemental wires can also be decreased in size, so the mounting or packing density (effective cross sectional area or stress area) of the individual elemental wires can be further improved.
  • the lubricant is impregnated into the core rope 2 and the individual outer layer strands 3, so friction between the individual elemental wires 8 through 16 of the elevator rope 1 can be reduced, and the wear of the individual elemental wires 8 through 16 can be suppressed. Accordingly, it is possible to further increase the life span of the elevator rope 1.
  • the collective breaking load of the core rope 2 is set to be equal to or less than 0.6 times the collective breaking load of all the outer layer strands 3.
  • the strength bearing ratio of the outer layer strands 3, for which a determination as to whether rope replacement is necessary is made can be made large. Accordingly, it is possible to make such a determination as to whether the replacement of the elevator rope 1 is necessary in a more accurate manner only by observing the state of the individual outer layer strands 3, whereby the occurrence of an incorrect determination as to whether the replacement of the elevator rope 1 is necessary can be prevented.
  • the individual outer layer strands 3 are twisted in a direction opposite to the twisting direction of the individual inner layer strands 6, so the untwisting torque of the elevator rope 1 can be reduced.
  • the collective breaking load of the core rope 2 is set to be equal to or less than 0.6 times the collective breaking load of all the outer layer strands 3, it is preferable that such a setting be in a range of from 0.4 times to 0.6 times.
  • Fig. 4 is a cross sectional view that shows a rope for an elevator according to a second embodiment of the present invention.
  • the cross sections of elemental wires 8 through 10 of a core strand 4 are made to deform by compressing the core strand 4 from its outer periphery.
  • the cross sections of elemental wires 11 through 13 of each inner layer strand 6 are also made to deform by compressing the inner layer strand 6 from its outer periphery.
  • the cross sections of elemental wires 14 through 16 of each outer layer strand 3 are also made to deform by compressing the outer layer strand 3 from its outer periphery.
  • the cross sections of the individual elemental wires of the core strand 4, the inner layer strands 6 and the outer layer strands 3 are deformed to take irregular shapes by individually compressing the core strand 4, the inner layer strands 6 and the outer layer strands 3 from their outer peripheries.
  • the construction of this embodiment other than the above is similar to that of the first embodiment.
  • the cross sections of the elemental wires of each of the core strand 4, the inner layer strands 6 and the outer layer strands 3 are deformed to take irregular shapes by individually compressing the core strand 4, the inner layer strands 6 and the outer layer strands 3 from their outer peripheries. Accordingly, gaps between individual elemental wires in each of the individual strands 4, 6, 3 can be further decreased in size, whereby the mounting or packing densities (effective cross sectional areas or stress areas) of the individual elemental wires 8 through 16 can be improved.
  • the outer peripheral portions of the individual strands 4, 6, 3 are smoothed by making the individual elemental wires to be deformed, so even when the individual strands 4, 6, 3 are in contact with one another for example due to aging deterioration, production errors, etc., it is possible to further decrease the contact pressure between adjacent ones of the individual strands, thereby making it possible to extend the life span of the elevator rope 1.

  • the inner layer strands 6 and the outer layer strands 3 are individually compressed from their outer peripheries to deform only the cross sections of the individual elemental wires 8 through 13 of the core strand 4 and the inner layer strands 6, whereas the deformation of the cross sections of the elemental wires 14 through 16 of the outer layer strands 3 is blocked or inhibited.

  • the cross sectional shapes of the elemental wires 14 through 16 when twisted with one another are left as they are.
  • the core strand 4 and the inner layer strands 6 are covered at least with the outer layer covering member 7, so the lubricant in the interior thereof is less liable to flow out to the outside. Accordingly, the lubrication condition in the interior of each of the core strand 4 and the inner layer strands 6 is also less liable to deteriorate even if the elevator rope 1 is used over the years.
  • the outer layer strands 3 are adapted to be in direct contact with the sheave 21, so the lubricant in the interior thereof is liable to flow out to the outside due to, for example, the migration of the lubricant to the sheave 21 or the like. Accordingly, if the elevator rope 1 is used over the years, the lubrication condition in the interior of the outer layer strands 3 becomes liable to deteriorate.
  • the lubricant in the interior of the outer layer strands 3 becomes liable to be squeezed out due to deformation processing, in addition to which gaps between adjacent ones of the elemental wires 14 through 16 for holding the lubricant are also decreased. Accordingly, the lubrication condition in the interior of the outer layer strands 3 becomes more liable to be deteriorated.
