Embodiment approach 1
[0031] First, a structure of an elevator rope 1 having a rope core 2 obtained by bundling a plurality of fiber bundles 4 as a core material without twisting will be described. Next, the strength of the elevator rope 1 having the rope core 2 in which the fiber bundles 4 are bundled without twisting will be described, and the features of the present invention will be described.
[0032] figure 1 It is a cross-sectional view of an elevator rope 1 having a rope core 2 obtained by collecting 4 fiber bundles as a core material. The elevator rope 1 according to Embodiment 1 has a plurality of (eight in this example) steel strands 3 arranged on the outer periphery of the rope core 2 and composed of twisted strands. The elevator rope 1 has a structure in which eight steel strands 3 are wound around a rope core 2 , and has a structure of, for example, 8×S (19), 8×W (19), or 8×Fi (25) defined in JISG3525. Steel strands 3 are used for the elevator rope 1 of the present embodiment, but t...
Embodiment approach 2
[0058] In this embodiment, the respective outer peripheries of the fiber bundles 4 as the core material are covered with the core material coating material 8 as the resin, and the coated core material 12 bundles coated with the core material coating material 8 are collected, Thereby, the rope core 11 is integrated, and it differs from Embodiment 1 in this point. In this embodiment, the material of the core material is not limited either. In this embodiment, the fiber bundle 4 will be described as a core material.
[0059] Figure 8 It is a sectional view of the elevator rope 10 of Embodiment 2. Like Embodiment 1, the elevator rope 10 of Embodiment 2 has a plurality of (eight in this example) steel strands 3 arranged on the outer periphery of a rope core 11 and composed of twisted strands. The rope core 11 is covered by the rope core covering material 7 . A plurality of fiber bundles 4 serving as core materials are respectively coated with a resin of the core material coati...
Embodiment approach 3
[0073] This embodiment differs from Embodiments 1 and 2 in that the number of steel strands 16 arranged on the outer periphery of the rope core 11 is twelve.
[0074] Figure 11 It is a sectional view of the elevator rope 15 of Embodiment 3. Figure 11 It is a figure in the case of applying the rope core 11 of Embodiment 2. The rope core 11 according to Embodiment 2 has fiber bundles 4 and a coated core material 12 in which the fiber bundles 4 are coated with a core material coating material 8 as a core material, and the rope core 11 is coated with a rope core coating material 7 . In this embodiment, the rope core 11 is applied, but it is not limited thereto, and any rope core having a higher mass than strength may be used. The rope cores 2 and 6 described in Embodiments 1 and 2 are also included.
[0075] In the elevator rope 15 of Embodiment 3, compared with the structure in which eight steel strands 3 are wound as shown in Embodiments 1 and 2, the cross-sectional area of...
