FILLED-TYPE LINEAR CONTACT STRUCTURE STEEL WIRE ROPE

摘要

A filled-type linear contact structure steel wire rope and a manufacturing method therefor. The steel wire rope comprises a core, strands, and filler wires or filler strands or partially filler wires and partially filler strands, the core and the strands being point contact or linear contact strands, the strands and the filler wires or filler strands or partially filler wires and partially filler strands being formed and twisted on the core in one step, gaps between the core and the strands being filled with the filler wires or filler strands or partially filler wires and partially filler strands having a certain steel wire tensile strength, the strands and the filler wires or filler strands or partially filler wires and partially filler strands being synchronously led to a closure point during rope twisting, forming the product in one step. The filler wires or the filler strands are used to increase the density coefficient of the steel wire rope. Given the same steel wire tensile strength, the new structure increases the filled area by 3-5% in a product having an equivalent diameter design, and correspondingly increases the breaking force by 3-5%.
