    Abstract: 本发明提供一种用于如钢水包起重机之类的重负荷起重机上的钢丝绳,该钢丝绳不仅几乎抗旋转,而且还不易因钢丝的磨损和疲劳而断裂。抗旋转钢丝绳有多根侧股,在每一侧股中,钢丝按与芯股钢丝拧法相同的方向在芯股周围拧成股。侧股按与芯股钢丝拧法相反的方向拧成股,从而形成钢丝绳。侧股的间距倍数最好小于钢丝绳的间距倍数。侧股直径与芯股直径之间的比率最好为大约1.3到大约1.8。股间距倍数最好为大约5到大约8,且钢丝绳间距倍数最好为大约8到大约10。芯股和侧股最好均含有在最外一层有扁平表面的成型钢丝。

    Abstract: Provided is a steel cord for reinforcing a rubber article which can further improve cut resistance when applied to a tire while maintaining the amount of steel to be used. A steel cord for reinforcing a rubber article comprising: one core strand 11 having a two-layered layered-twisted structure formed by twisting a plurality of steel filaments 1; and a plurality of sheath strands 12 having a layered-twisted structure formed by twisting a plurality of steel filaments 2, wherein the sheath strands are twisted around the core strand. A ratio dc/ds of a diameter dc of a sheath filament constituting the sheath of the core strand to a diameter ds of an outermost layer sheath filament constituting the outermost layer sheath of the sheath strand is more than 1.25 and not more than 1.50.

    Abstract: A steel cord that is especially useful for reinforcing a crown portion of a tire is provided. In particular, a steel cord free from manufacturing problems existed in the conventional art and allowing for stable quality and good production efficiency is provided, and a rubber-steel cord composite and a tire that are equipped with the same are provided.A steel cord has a multiple-twist structure including N (N=2 to 8) strands 2 that are twisted together, each strand 2 having a plurality of wires 1 that are twisted together. When the diameter of each strand is denoted by d (mm), the diameter of a circle circumscribing the cord is denoted by D (mm), and the twisting pitch of the cord is denoted by P (mm), εc defined by the following expression, εc=√(−b/2+√(b2/4−c))−1 (where b denotes −1+π2(−4R2+d2)/P2, c denotes π2d2k(4π2R2+P2)/P4, R denotes (D−d)/2, and k denotes tan2(π/2−π/N)), satisfies εc≧0.005.
