Abstract
The utility model discloses a steel cord for a pedrail. The steel cord can improve the flexibleness of the pedrail and comprises a coating layer formed by a central cord and at least two outer layer cords twisted on the central cord. Each outer layer cord comprises a central steel wire, and at least two peripheral steel wires twisted on the central steel wire; and the central cord is formed by at least two steel wires through twisting. In the steel cord, the central cord is improved, the central steel wire is eliminated, and the six steel wires are twisted, thereby improving the flexibleness of the steel cord and reducing the density of the steel cord. The pedrail made of the steel cord better solves series of problems caused by the fracture of the central steel wire in the central cord of the steel cord in the original track pedrail, which bother people for a long time and remain unsolved. Additionally, the manufacturing cost is lower, the service life is longer, and the fatigue resistance is increased by 20 percent.
Description
Technical field
The utility model relates to the steel cord, refers more particularly to steel cord for caterpillar belt.
Background technology
Present steel cord for caterpillar belt, as shown in Figure 1, its structure comprises: center strand 1 and the clad that is made of the outer strand 2 of the six roots of sensation that is stranded on this root center strand 1, center strand 1 has identical structure with outer strand 2, is made of with the six roots of sensation peripheral steel wire 12 and 22 that is stranded on this root core wire 11 and 21 core wire 11 and 21 respectively.The flexibility of the crawler belt of being made as skeleton by this steel cord is relatively poor, after long-term the use, core wire in the center strand of steel cord can rupture, the core wire of fracture can puncture the rubber layer that is coated on steel cord outside, not only have influence on the service life of crawler belt, and exposed core wire outside also can have influence on the normal operation of the relevant devices such as harvester that this crawler belt is installed.
The utility model content
Technical problem to be solved in the utility model is: a kind of steel cord for caterpillar belt that improves the crawler belt flexibility is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: steel cord for caterpillar belt, comprise: center strand and by at least two clads that outer strand constitutes that are stranded on this root center strand, every outer strand comprises: core wire and be stranded at least two peripheral steel wire on this root core wire, described center strand is twisted together by at least two steel wires.
Described center strand is twisted together by six roots of sensation steel wire, and described clad is made of the outer strand of the six roots of sensation, and every outer strand is made of a core wire and the six roots of sensation peripheral steel wire that is stranded on this root core wire.
The beneficial effects of the utility model are: the utility model is improved the center strand, has removed core wire, directly many steel wires is twisted together, and has improved the flexibility of this steel cord, has reduced the density of this steel cord.With the crawler belt that this steel cord is made, solved well that people thirst for solving always and the core wire fracture of unsolved original crawler belt invar cord center strand and a succession of problem of causing; And manufacturing cost is lower, longer service life, and its anti-fatigue performance has improved about 20%.
