18×7类钢丝绳结构形式为在中心结构外依次捻制内层股和外层股,而与之同为2层股结构的23×7类钢丝绳,由于外层绳股数、组绳总股数相对较多,使在内层股谷部增加填充股成为现实,故其结构形式增加1种。2类钢丝绳层绳捻法配置涉及钢丝绳抗旋转性、组绳不同层股钢丝接触应力、生产技术难度等多种因素,不可一概而论。在破断拉力、抗旋转性能、抗冲击性能方面,23×7类钢丝绳具有明显优势。 18 × 7 type of wire rope structure in order to twist the inner and outer layers of the core structure in turn outside the structure, and with the same 2-story structure of 23 × 7 wire rope, the outer rope strand number, Relatively more number, so that the increase in the inner layer of stocks filled with a reality, so the structure of an increase of 1 species. Category 2 rope layer rope twist method involves the anti-rotation of the rope, the different layers of wire rope contact stress, the difficulty of production technology and other factors can not be generalized. In the breaking force, anti-rotation performance, impact resistance, 23 × 7 category rope has obvious advantages.
