- a steel cord is disclosed in which five sheath strands having the same diameter as the core strand are twisted around each other.
- an object of the present invention is to properly balance the cord structure and the gap amount between the filaments constituting the cord in the cord of the double twist structure, so that the rubber penetrability (rust resistance), the cord strength and the shear resistance are obtained.
- An object of the present invention is to provide a steel cord for reinforcing rubber articles that is compatible with the above.
- the steel cord for reinforcing rubber articles of the present invention has one core strand having a layer twist structure formed by twisting a plurality of steel filaments and a layer twist structure formed by twisting a plurality of steel filaments.

- the number of the sheath strands is preferably 7 to 9. In the cord of the present invention, it is preferable that all the filaments constituting the core strand have the same diameter. Furthermore, in the cord of the present invention, the cord diameter is preferably 5.00 mm or more.
- the average value Lc of the gap amount between the outermost sheath filaments constituting the outermost sheath of the core strand and the outermost sheath filament constituting the outermost sheath of the sheath strand exceeds 1 and is 1.5 or less.
- the core strand has a two-layer structure.
- the pneumatic tire of the present invention is characterized by using the steel cord for reinforcing rubber articles of the present invention as a reinforcing material.
- FIG. 1 and 2 are cross-sectional views in the width direction showing one configuration example of the steel cord for reinforcing rubber articles of the present invention.
- the cord shown in FIG. 1 includes a single core strand 11 having a two-layer twisted structure formed by twisting a plurality of steel filaments 1 and a two-layered twist formed by twisting a plurality of steel filaments 2.
- the sheath strand 12 is composed of a plurality of structures having the structure, in the illustrated example, eight sheath strands 12.
- the core strand 11 has a 3 + 8 structure in which a sheath is formed by twisting eight sheath filaments 1b around a core made of three twisted core filaments 1a.

- it is effective to increase the gap amount between the filaments, and particularly with respect to the total gap amount between the outermost layer filaments for the core strand located at the center of the cord. The larger the amount per gap, the better the rubber penetrability.
- the average value Lc of the gap amount between the outermost layer sheath filaments of the core strand is defined in the above range, and the number of outermost sheath filaments is set in the range of 7 to 10, thereby increasing the cord strength.
- a cord that has improved rubber penetration and improved rust prevention while ensuring shear resistance is realized.
- the average value Lc of the gap amount between the outermost layer sheath filaments of the core strand is defined as the strand from the circumference of a virtual circle or ellipse passing through the center point of all the outermost layer filaments constituting the strand. It is a calculated value obtained by subtracting the sum of the diameters of the outermost layer filaments to be formed and dividing by the number of outermost layer filaments constituting the strand.
- the average value Lc of the gap amount between the outermost sheath filaments needs to be 0.073 to 0.130 mm, preferably 0.100 to 0.110 mm. When the average value Lc of the gap amount between the outermost sheath filaments is less than 0.073 mm, sufficient rust prevention properties cannot be obtained, and when it exceeds 0.130 mm, the cord strength and shear resistance are insufficient. .

Since the core strand located at the center of the cord is less likely to penetrate the rubber than the sheath strand located around the core strand, from the viewpoint of further improving the rust prevention property, the average value of the gap amount between the outermost sheath filaments is It is preferable that the core strand is larger than the sheath strand.
- the average value Ls of the gap amount between the outermost sheath filaments of the sheath strand is a value obtained in the same manner as the average value Lc of the gap amount between the outermost sheath filaments of the core strand.
- the number of layers of the core strand layer twist structure is not particularly limited, and may be, for example, 2 to 3 layers. Therefore, when the first sheath and the second sheath are sequentially formed from the inside of the layer twist structure, when the core strand 11 has a two-layer twist structure as shown in FIG. 1, the outermost layer sheath of the core strand 11 is When the core strand 31 has a three-layered layer structure as shown in FIG. 2, the outermost layer sheath of the core strand 31 is the second sheath. Further, the number of layers of the layer twist structure of the sheath strand is not particularly limited, and may be, for example, 2 to 3 layers.
- the outermost sheath of the sheath strands 12 and 32 is the first sheath. .

If the core strand and the sheath strand are all the same diameter and the sheath strands are in the close-packed state so that there is no gap between them, six sheath strands can be arranged. In the present invention, as shown in the figure, the diameter of the sheath strand 12 is made smaller than the diameter of the core strand 11 so that 7 to 9 sheath strands 12 can be arranged. Therefore, by setting the number of sheath strands 12 to 9 to 9, the resistance of the core strand to the tightening force of the sheath strand can be improved, and the cut resistance of the cord can be improved.

- the core strand 11 it is possible to improve the shear resistance by making the core filament 1a smaller in diameter than the sheath filament 1b, but in this case, it is difficult to ensure the gap amount between the sheath filaments. It becomes. Therefore, when the core strand has a two-layer structure, it is preferable that all the filaments 1 constituting the core strand 11 have the same diameter.
- FIG. 1 As shown in FIG.
- the core filament 21a and the first sheath filament 21b all have the same diameter. Is preferred. If the core filament 21a has a smaller diameter than the first sheath filament 21b in the core strand 31, it will be difficult to ensure a gap between the first sheath filaments. Therefore, when the core strand has a three-layer structure, it is preferable that the core filament 21a and the first sheath filament 21b have the same diameter.
- the cord diameter of the cord of the present invention is preferably 5.00 mm or more, for example, 5.00 to 6.00 mm.
- a cord having a large diameter of 5.00 mm or more it is possible to ensure both strength and cut resistance required for large tires used in large vehicles such as construction vehicles. .
