Steel cord for reinforcing a rubber product |
摘要 |
<p>A steel cord which is suitable for reinforcing a rubber product and has excellent fatigue resistance. The steel cord has a layer-twisted structure formed by steel filaments respectively having a diameter of 0.15 mm to 0.25 mm. A core of the steel cord is formed by 1 to 4 steel filaments. A least 6 steel filaments are wound around the steel filaments of the core to form at least one layer. When the steel cord is bent from a straight state to a state in which a radius of curvature thereof is d/(17 x 10<-><3>) wherein d is a diameter in millimeters of each steel filament in an outermost layer of the steel cord, a maximum amount of movement of each steel filament in the outermost layer in a cross-section of the steel cord is less than or equal to (-0.5454d + 0.1454) x 10<3> um. The steel cord preferably has a two-layer-twisted structure or a three-layer-twisted structure, and has an arrangement in which the diameters of the steel filaments gradually decrease from the core to the outermost layer. <IMAGE> <IMAGE></p> |
