Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 to 4, the lossless bearing steel wire of the present embodiment includes a steel core 1; the steel core 1 is made by four steel wires intertwine, and the surface of steel core 1 is provided with protective structure, and protective structure includes

endotheca

2, and 2 covers of endotheca are established on the surface of steel core 1, and the surface cover of endotheca 2 is equipped with sponge layer 3, and the fixed surface of sponge layer 3 is connected with overcoat 4, and the fixed surface of overcoat 4 is connected with cushion 5, and the fixed surface of cushion 5 is connected with inoxidizing coating 6.

Referring to fig. 1, the protective structure further comprises a plurality of inner cavities 7, the inner cavities 7 are formed in the surface of the sponge layer 3, and the inner cavities 7 are uniformly arranged in a surrounding manner by taking the steel core 1 as an axis.

This embodiment can improve the buffering effect on sponge layer 3 through setting up inner chamber 7, can form the chamber that separates the temperature simultaneously, reduces inside and outside temperature exchange influence.

Referring to fig. 4, the surface of the steel core 1 is provided with a longitudinal groove 8, the length of the longitudinal groove 8 is equal to the length of the steel core 1, and two ends of the longitudinal groove 8 are communicated with two ends of the steel core 1.

This embodiment can reduce the area of contact of steel core 1 through setting up longitudinal groove 8, prevents to produce the loss because of the friction between the adjacent steel core 1.
