A kind of hose for soft transmission shaft and its production method

Abstract

The invention provides a flexible pipe for a flexible drive shaft, which aims at reaching the purposes of high tensile strength and prolonging of service life in application. The flexible pipe for theflexible drive shaft is characterized by sequentially comprises a lining spring, a first lining fabric layer, a first steel wire weaving fixed skeleton, an inner adhesive layer and an outer adhesivelayer from interior to exterior. The invention also provides a production method of the flexible pipe for the flexible drive shaft. The flexible pipe has the advantages that by using a dense net whichis weaved by multiple ingots and multiple steel wires, a canvas without a fabric wiping adhesive is completely, uniformly and fixedly arranged at the outer layer of the lining spring along the warp,so that the use of gasoline is avoided; the applied material adopts the complete canvas with fabric wiping adhesive-free inner layer along the warp, the canvas with complete yarns has strong tension,a shaft pipe is not tensioned and shortened in use, and the tension deformation of the flexible pipe is avoided; especially, when the flexible pipe is applied to concrete vibration rods, the tensile,torsion and rapture strengths of the flexible pipe of the vibration rod are enhanced, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of construction engineering equipment, in particular to a hose for a soft transmission shaft and a production method thereof. Background technique [0002] The hose for the soft transmission shaft is sheathed outside the soft transmission shaft, so that the soft transmission shaft is inside the hose and transmits force through different rotational speeds. In the production method of the flexible transmission shaft hose used in the prior art, the high-quality cold-rolled steel strip is wound into a spiral tube shape, and then the oil stain on the surface is cleaned with gasoline, after the oil stain is removed, the pulp glue is applied, and then the rubber canvas is wrapped and described slurry glue is made with gasoline dissolving rubber, needs a large amount of gasoline, is inflammable and explosive, volatilizes a large amount of gasoline and the smell of sizing material, not only increases the unsafe facto...

In the production method of the flexible transmission shaft hose used in the prior art, the high-quality cold-rolled steel strip is wound into a spiral tube shape, and then the oil stain on the surface is cleaned with gasoline, after the oil stain is removed, the pulp glue is applied, and then the rubber canvas is wrapped and described slurry glue is made with gasoline dissolving rubber, needs a large amount of gasoline, is inflammable and explosive, volatilizes a large amount of gasoline and the smell of sizing material, not only increases the unsafe factor when making, and is harmful to environment There is a certain amount of pollution, which also makes the manufacturing process of the hose complicated and cumbersome; when the canvas is applied, in order to adhere the canvas to the lining spring and prevent the rubber from leaking into the lining spring, the canvas is obliquely cut into strips for use, resulting in the failure of the final product. The hose has a certain degree of stretchability and shrinkage, which affects the performance of the soft drive shaft
