    Abstract: PROBLEM TO BE SOLVED: To provide a steel cord for reinforcing a rubber article, by preventing the preceding breakage of filaments and improving the strength at break of the steel cord as a whole, and to provide a pneumatic tire using the same.
    SOLUTION: This double-twisted structure steel cord is provided by twisting a core filament 11 with at least one layer sheath filaments 21 as a layer-twisted structure to form one strand, further twisting in a plurality of strands as the layer-twisted structure consisting of a core strand 1 and at least one layer of sheath strands 2 to make one steel cord. The tensile strength of the filament for forming the strand is made as "the tensile strength of the filament in a layer close to the center of the strand"≥"the tensile strength of the filament in a layer far from the center of the filament", and the mean tensile strength of the strand for forming the steel cord is made as "the mean tensile strength of the layer close to the center of the steel cord"

    Abstract: 平衡性可绕性俱佳的电梯钢丝绳,其结构包括中心股、内层股、和外层股,所述内层股对称地包捻中心股,所述外层股对称地包捻在钢丝绳最外侧。本实用新型结构简单、合理、紧凑,由于所述钢丝绳是由8个外层股包捻中心子绳捻制而成,每个外层股是由内层6根粗钢丝和外层6根粗钢丝、6根细钢丝包捻一根中心钢丝呈瓦林吞式捻制而成。这种结构的钢丝绳具有较高的抗疲劳弯曲性能,大大提高了钢丝绳的可绕性,进而提高了钢丝绳的承载能力。此电梯用钢丝绳的平衡性、可绕性以及承载能力俱佳,可以降低钢丝绳的伸长率。
