Abstract
As an inherent property of steel wire ropes,torsion coefficient determines the anti-rotation performance of steel wire ropes in use.It is related to the geometric structure parameters of steel wire rope,including the number of steel wires(strands)in each layer,the nominal diameter of steel wires(strands)in each layer,the twist angle of strands(ropes)in each layer and the twist direction(twisting method)of strands(ropes).Taking 6×7-WSC steel wire rope as an example,it is explained that the twist direction of strand(rope)is the core factor affecting the torque coefficient of steel wire ropes.In addition,taking a 6×19S-IWRC steel wire rope with a nominal diameter of 38 mm as an example,the twist directions of steel wire ropes and the twist directions of the strands were subject to permutation and combination,and the torque coefficients of steel wire ropes with 32 different twist directions were calculated.The calculation results show that the torque coefficient of wire ropes twisted in the same direction is 1.56 times that of wire ropes twisted in the different direction,that is,the anti-rotation performance of the wire rope twisted in the different direction is better than that of the wire rope twisted in the same direction,and the twisting method of wire ropes twisted in the left and right directions is in mirror symmetry.关键词
