Embodiment Construction
[0018] As shown in the figure, the tensile assembly includes a wrapping body 1 and a carrier body 2 , and the carrier body 2 is composed of a coating layer 3 and a carrier core wire 4 . There are 9 strands on the periphery of the load-bearing core wire 4 . In the center of the load-bearing core wire 4 there is a strand. Each strand of the carrying core wire 4 is formed by parallel twisting of a plurality of metal core wires. In this way, the contact between the metal core wires of each strand is a line contact, so the contact stress between the metal core wires is reduced. At the same time, the carrying core wire 4 can maintain a good shape. In order to improve the bending fatigue strength of the load-bearing core wire 4, the metal core wire is required to be relatively thin, about 0.15-0.6 mm. In addition, in order to further increase the bending fatigue life of the load-bearing core wire 4 , the ratio of the diameter of the load-bearing core wire 4 to the diameter of the ...
