  • Each wire 2 is covered with a wire coating 4, the whole of the rope 1 is coated with an intermediate coating material 6, and its outermost layer is covered with a rope coating 5.
  • the maximum bending stress ( ⁇ bmax) occurs in an outermost layer of each wire 2 in a cross section, and the value of the stress is proportional to distance from a center of the wire 2. That is, the value is proportional to the diameter ⁇ of the wire 2.

  • the sheave diameter D is reduced to 100 mm, the rope diameter d is set to 12 mm, and the wires constituting the rope 1 have a diameter ⁇ of about 0.25 mm, the value D/d becomes 8.3 mm.
  • the bending stress ⁇ b occurring in the wire 2 can be reduced by reducing the diameter ⁇ of the wire 2 as described above.
  • the diameter of the wire 2 affects the life of the rope if the abrasion by mutual movement of the wires 2, which is a life factor concerning the rope, is taken into consideration.
  • the mutual movement of the wires 2, that is, slippage distance increases as the rope diameter d increases.
  • the rope diameter d is small.
  • reduction of the rope diameter d also reduces the breaking strength of the rope 1, so that the breaking strength of the wires 2 must be increased. Therefore, the wires 2 constituting the rope 1 may have a breaking strength of 1,770 MPa or more.
  • each wire 2 is covered with the wire coating 4 in order to reduce abrasion caused by the mutual movement of the wires 2.
  • the wire coating 4 is composed of a resin such as polyethylene, polyamide, ethylene tetrafluoride, polyurethane, epoxy, or vinyl chloride.
  • the wire coating 4 has a smaller modulus of elasticity in comparison with steel, so that when the wires 2 come into contact with each other, a sufficient contact area is obtained to allow the wires to slide under a low surface pressure. As a result, the wires 2 are prevented from coming into local concentrated contact with each other, thereby reducing their abrasion.
  • the wire coating 4, intended to reduce the abrasion of the wires 2, is formed of material undergoing lower plastic flow pressure than steel, that is, soft coating material.
  • Frictional force associated with mutual contact slippage of the wires 2 is generally represented by the product Aw ⁇ s of the contact area Aw and the shearing strength s of the material.
  • the contact area Aw substantially equals (vertical load)/(plastic flow pressure of the material), so that steel, which is a base material, has a small contact area.
  • shearing associated with the mutual slippage of the wires 2 is received by the wire coating 4, which is formed of soft coating material with a low shearing strength, and the vertical load is supported by the steel wires 2, which is the base material, so that low friction is obtained.

That is, as described above, reduction of contact surface pressure is effective in reducing the amount of the abrasion.
  • the case in which the entire rope 1 is covered with the coating in a closed state and comes into contact with the sheave groove can increase the radius of curvature at contact points to enlarge the contact area, that is, reduce the contact surface pressure. Further, other than the radius of curvature at the contact points, it is possible to increase the contact area and to reduce the contact pressure by lowering the modulus of elasticity of the material.
  • the intermediate coating material 6 is arranged between the wires 2 and the rope coating 5 applied to the outermost layer and reduces abrasion of the rope coating 5 from the inside. Further, the rope coating 5 also has a function of shielding the entire rope 1 from the ambient air, thereby improving the corrosion resistance of the rope 1. Therefore, the rope 1 ensures stable reliability and life even in mechanical systems installed outdoors. Further, it is desirable that the rope coating material is inflammable. Furthermore, the rope coating 5 can be arbitrarily colored, and therefore, it is possible to make the mechanical systems installed outdoors or indoors have wide possibility in design thereof.
  • the steel wires 2 do not directly contact with each other or with the sheave groove.

  • the method of twisting the rope 1 used in the mechanical system includes Lang's lay that the wires 2 and the strands 3 are twisted in the same direction and ordinary lay that the wires 2 and the strands 3 are twisted in opposite directions.

  • the driver 59 is shown to overhang above the cage 51 but may be installed in a gap between the cage 51 and an elevating passage wall 64 using a thinner motor or reduction gear.
  • the under-cage pulleys 52, sheave 56, and counterweight pulley 58 in FIG. 8 may have smaller diameters than those in an elevator with a conventional rope.
  • the elevating passage for the elevator has a pit dug in a bottom thereof as a free space.

  • the cage 51 is generally provided with an emergency stop device that brakes the cage 51 when the rope 53 is broken. Since the total weight of the cage 51 and the under-cage pulleys 52 decreases, braking force needed to the emergency stop device is reduced, whereby it is possible to make the emergency stop device lighter than conventional devices.

  • a geared type driver it is possible to reduce the reduction ratio of the reduction gear or omit the reduction gear. This makes it possible to reduce an area of an installation space for the driver 59 located at the top of the elevating passage, thus obtained is advantage for reducing an amount of protrusion of the elevating passage if a ceiling of the building on the top floor is low.
  • the sheave 56 and the counterweight pulley 58 be substantially linearly arranged in the gap between the cage 51 and the elevating passage wall 64.
  • an installation position of the counterweight pulley 58 is shifted in the direction of arrow A in the drawing. This enlarges a gap between the elevating passage wall 64 and the counterweight 57, above in the drawing, thereby making it possible to increase the width dimension (dimension B in the drawing) of the counterweight 57.
  • the life of the rope 53 is extended, so that it is possible to extend rope replacement period. That is, the coefficient of friction between the rope 53 and the sheave 53 becomes larger than the case in which a conventional rope is used, so that it is possible to reduce pressing force of rope 53 against the sheave 56.
  • the pressing force is generated by tension of the rope resulting from the total weight of the cage 51 and the counterweight 57. Accordingly, slippage never occur between the rope 53 and the sheave 56 even if the pressing force is reduced, that is, the total weight of the cage 51 and the counterweight 57 is reduced. With this, obtained is advantage to reduce the manufacturing costs of the cage 51 and the counterweight 57 as well as the capacities of the driver 59 and the power source.
  • the longitudinal axes of the under-cage pulleys 52 and the sheave 56 are substantially perpendicular to each other rather than extending in the same direction. If a conventional flat belt is used in an elevator of such layout, the belt is twisted between the under-cage pulleys 52 and the sheave 56. The twisted flat belt obliquely enters the under-cage pulleys 52 and the sheave 56, which becomes a cause of partial wear or an instability of the friction characteristic.
  • the rope 53 of the present invention is substantially circular in cross section and therefore, there is no case in which a partial wear is resulted and the frictional characteristic becomes unstable, even if a layout in which twisting of the rope occurs is employed.
  • resin fiber ropes may be altered or degraded when exposed to ultraviolet rays, and thus cannot be used under conditions that sunlight is incident directly or indirectly on the elevating passage as in the case with observation elevators or elevators provided at outdoor.
  • the rope of the present invention uses steel wires as strengthen members for bearing loads. Therefore, it is not degraded even when exposed to ultraviolet rays but can be used even in the environment described above.
  • the resin fiber rope may be altered to have its strength extremely reduced. Accordingly, when used in an elevator, the resin fiber rope may be broken by a fire in the building depending on its material. Further, when a flat belt with steel twisted wires becomes hot due to a fire in the building, sheathing resin material used to bundle the steel twisted wires may melt to allow the twisted wires to be entangled with each other, thereby causing the elevator to malfunction.
  • the rope of the present invention uses steel wires as strengthen members for bearing loads. Consequently, even if the elevating passage becomes hot because of a fire, only the resin coating material may melt and the strength is maintained up to about 1,000°C as in the case with conventional wire ropes.
  • the strength of the rope must be further increased.
  • the rope 53 of the present invention has a lighter weight per unit length than conventional wire ropes of equivalent strength.
  • the rope of the present invention is light weight and therefore, rope transporting, installing, and removing operations performed when the elevator is installed or the rope is replaced with a new one become easy.
  • the resin fiber rope generally has large initial elongation when it is initially used, and its length must be adjusted after a fixed time lapsed from the installation. This is because the resin fibers are softer than steel wires, so that it takes much time that the fibers are adapted to each other and come into close contact with each other.
  • the center of the rope of the present invention is structure by steel wires, and therefore, its initial elongation becomes stable early as in the case with conventional wire ropes, thereby eliminating the need to adjust the rope length again.
  • the rope of the present invention has its surface coated with the resin, and therefore, it can be arbitrarily colored by properly selecting the type of the resin or mixing a pigment into the resin.
  • the presence of the rope can be made unnoticeable by making it in the same color as that of the building or elevating passage, or conversely, the operation of the elevator can be emphasized by making it in a color completely different from that of the building or elevating passage.
  • different parts of the rope may be made in respective colors, so that different combinations of colors are viewed depending on the vertical position of the cage 51. In this case, it is needed to prevent the resin layer from being separated at boundaries of the colors.
