三角股钢丝绳,属于异形股钢丝绳中的一种。异形股钢丝绳习惯上常分为三角、椭圆和扁股者三类;若按所组成之钢丝绳的结构特点也可基本分为三角和椭圆股者两大类。这是因为,椭圆股和扁股在股的构造上就十分相似,区别仅仅在于椭圆度不同,而在其组成钢丝绳时,均可用以制造5股以上的多层股(不扭转)和单层股(扭转)的钢丝绳;三角股则只可能用以制造单层的6股钢丝绳。异形股可使所组成之钢丝绳的外轮廓,接近于半密封式结构钢丝绳的形状,而不显著降低钢丝绳的可挠性。由于异形股的各个股面,比圆形股的曲率大为减小,而使钢丝绳的外表面,没有太大的缺空,工作时与卷鼓或绳轮之沟槽的接触面大大增加,各钢丝上分担的压力减小,磨耗亦减少,其使用寿命比圆股(包括线接触者)钢丝绳成倍
Triangle wire rope, wire rope belonging to a special-shaped one. Special-shaped wire rope used to be often divided into triangle, oval and flat-necked three categories; if the composition of the wire rope can also be divided into the basic characteristics of the triangle and the oval-shaped stocks are divided into two categories. This is because the elliptical and flat strands are very similar in the construction of the strands, with the only difference being in the ovality that they can be used to make more than 5 strands of strands (non-twisting) and monolayers (Twisted) wire rope; triangular stocks can only be used to make a single layer of 6 wire rope. The profiled strand allows the outer contour of the formed wire rope to be close to that of a semi-hermetic structural wire rope without significantly reducing the flexibility of the rope. Due to the various strands of the profiled strand, the curvature of the circular strands is greatly reduced, the outer surface of the rope is not greatly shorted, the contact surface with the groove of the drum or sheave greatly increases in work, The pressure on the steel wire is reduced, the wear is also reduced, and its service life is doubled than that of the round wire (including the line contact)
