Abstract
A caterpillar band steel cord comprises a steel cord body (2) which is formed by 3-7 central folded wires (1) in an identical-direction-twisting mode. Each folded wire (1) is formed by 3-27 inner layer brass plated steel wires (3) in a twisting mode. The caterpillar band steel cord has the advantages that electroplated brass is arranged on the surface of each steel wire and has the advantages of being hard to oxidize, good in flexibility, high in melting point, strong in binding capacity with rubber and the like, so that the diameter roughness of each steel wire is fine, compared with a radial tyre steel cord, higher openness is achieved, binding degree with the rubber is higher, tensile strength is high, the diameter is small, the using amount of the rubber can be greatly lowered, the thickness of a caterpillar band is lowered, service life of the caterpillar band is prolonged, and meanwhile the capacity to resist bad environment is greatly strengthened.
Description
Technical field
The utility model relates to steel cord technical field, specifically a kind of crawler belt steel cord.
Background technology
Rubber belt track steel cord, be by some brass plating steel wires by certain lay pitch and twist with the fingers to, be twisted into the product with certain structural steel tow.Be mainly used in short-distance and medium-distance and carry the framework material of the rubber belt track that matter is hard, sharp-pointed, block, high temperature resistant material is used, the crawler belt that is applicable to the solid material of stone pit, bulk coal, the sintering of steel plant, pelletizing, the larger crawler belt of drop and specific (special) requirements is carried.
The framework material that existing crawler belt is used is the steel wire rope of zinc-coated wire institute twisting.The defect such as have oxidation because metallic zinc has, flexibility is strong, fusing point is low with the adhesive power of rubber is poor, thin down to for a kind of obstruction the rugosity of steel wire diameter, thereby limited the attenuation of crawler belt thickness, resist ability and the service life of adverse circumstances.
Summary of the invention
The technical problems to be solved in the utility model is to provide the crawler belt steel cord that a kind of tensile strength is high, diameter is little.
The utility model crawler belt steel cord, these steel cord 2 You3-7Gen center strands 1 are stranded forming in the same way.
Described center strand 1 is by 3-27 root internal layer brass-plated steel wire 3 stranded forming.
The direction of lay of described brass-plated steel wire 3 is opposite with the direction of lay of center strand 1.
The advantage of the utility model crawler belt steel cord is: the surface of the utility model steel steel wire that cord utilizes is brass plating, it have be difficult to oxidation, flexibility is good, fusing point is high, with the advantages such as the adhesive power of rubber is strong, make the steel wire diameter rugosity thinner, than steel cords of radial tyre, have larger opening, higher with the degree of adhesion of rubber; Tensile strength is high, and diameter is little, can greatly reduce the use amount of rubber, and the thickness of attenuate crawler belt in the service life of prolongation crawler belt, is resisted simultaneously the ability of adverse circumstances and also greatly strengthened.
