SOLUTION: The wire ropes each having a fiber core 10a, 10b, 10c are equipped with a fiber-bundled core 1 produced by bundling multiple numbers of high strength fiber yarns 1a and impregnating with a lubricant, a braided coating layer 3 coating the fiber-bundled core 1 by braiding fibrous yarns 3a, 3b, and 6 or 12 wire strands 4a, 4b or 4c twisted around the braided coating layer 3. Also, the fiber-bundled core 1 is bundled and coated by a bundling members 2 (2a, 2b, 2c) capable of penetrating the lubricant for mediating the bundling member 2 between the fiber-bundled core 1 and the braided coating layer 3 in the wire ropes having the fiber cores 10a, 10b, 10c.

2. Description of the Related Art Conventionally, in an elevator or a lift, a fiber core impregnated with a lubricant by twisting a plurality of (three in the illustrated example) fiber strands formed of hemp or the like as shown in FIG. a (a + 9 + 9) twisted wire strands b and six (or eight, not shown) twisted into
A lightweight and flexible wire rope R with a fiber core having a lightweight and flexible structure configured in a × S (19) structure or an 8 × S (19) structure is widely used. Further, when the wire rope with the fiber core is repeatedly bent and deformed by using it for an elevator or a lift, etc., the fiber core is rubbed by the wire strand of the wire strand and the life is shortened. It is formed of natural fiber or synthetic resin fiber which is relatively hard to be worn and has low strength and large elongation.

Since the conventional wire rope with a fiber core has a structure in which a plurality of wire strands are twisted around the fiber core as described above, the fiber rope is formed by the strands of the wire strand. The core is easily rubbed locally, which contributes to a shortened life. In addition, since the fiber core is formed of a low-strength, large-strength fiber that is relatively hard to be rubbed as described above, the fiber core has a larger elongation than the wire strand and hardly contributes to the rope strength. There are problems with rope strength, durability, etc., such as the shape being easily deformed.

A wire rope 10 with a fiber core of the first embodiment
In a, the fiber bundle core 1 bundles a large number of high-strength fiber yarns 1a without twisting them, so that the fiber bundle core 1 effectively contributes to the rope strength with excellent high strength and high elasticity and small elongation. It is bundled and covered with the braided coating layer 3 or the fiber bundle member 2 to effectively prevent abrasion by the wire strand 4a. The core diameter of the fiber bundle core 1 is easily adjusted in accordance with the rope diameter by increasing or decreasing the diameter or the number of the high-strength fiber yarns 1a, and the fiber bundle core 1 is formed to have a uniform core diameter over the entire length. The wire strands 4a of the outer layer are filled through the braided coating layer 3 and the fiber bunching member 2 into the group of outer strands 4a, thereby effectively increasing the strength and durability of the ropes, such as increasing the support force of the wire strands 4a, that is, the rope shape retention force. I have. The braid coating layer 3 covers the fiber bundle core 1 directly or via the fiber bundle member 2 to cover the fiber bundle core 1. This braid mechanism has a moderate flexibility and the wire element of the wire strand 4a. It is easy to move following the line, so that the abrasion is reduced, and the abrasion of the fiber bundle core 1 is effectively prevented. The fiber bundle member 2 moderately strongly bundles the fiber bundle core 1, and the fiber bundle core 1 is further prevented from abrasion due to the bundle and coating by this interposition, and the rope shape retaining force by the fiber bundle core 1 is further increased. ing. The fiber bundle member 2 and the braided coating layer 3 allow the lubricant impregnated in the fiber bundle core 1 to permeate properly for a long period of time and have excellent lubricity and significantly increase the rope life. Furthermore, even if the braided coating layer 3 and the fiber bunching member 2 are applied, the weight and flexibility of the rope are not significantly impaired, and the weight and flexibility are secured almost in the same manner as in the conventional example. The sex etc. are effectively enhanced.

As apparent from Tables 1 and 2, the fiber cores of both comparative examples, which are formed of fiber yarns of relatively low strength and large elongation and whose elongation is further increased by twisting, have high strength. The fiber bundle core of each embodiment having a structure in which fiber yarns of small elongation are bundled has a significantly higher tensile modulus of elasticity, i.e., tensile strength, and significantly reduced core elongation, resulting in a significant increase in rope breaking force, i.e., rope strength. Have been.
In addition, it was confirmed that the above-mentioned effects and effects were obtained, such as the fatigue property, that is, the service life was effectively increased by the braided coating layer. In addition, in each embodiment other than the display,

According to the present invention, since the fiber bundle core having the above-mentioned structure is bundled without twisting a large number of high-strength fiber yarns, the rope has excellent high strength and small elongation. Contributing to the increase in strength, the braided coating layer or the fiber bundling member bundles and coats the fiber bundle core, effectively preventing the fiber bundle core from being abraded by a braid mechanism, etc., and also forms a rope together with the fiber bundle core. The rope strength and durability have been effectively increased by increasing the power. In addition, even if a braided coating layer or a fiber bundle member is applied, the weight and flexibility of the rope are not significantly impaired, and the weight and flexibility are secured almost in the same manner as the conventional example. And the cord strength and durability are effectively improved.
