Processing method for improving anti-torsion ability of shockproof lining

Abstract

The invention relates to a processing method which can improve the torsion resistance capacity of an anti-earthquake bush, aiming at the anti-earthquake bush in which an inner metal sheath is connected with an outer metal sheath by a rubber layer; after the rubber vulcanization molding process, radial compression processing is carried out to the excircle diameter of the outer metal sheath; the radial compression amount of the excircle diameter of the outer metal sheath is calculated by the following formula: Delta D is equal to (D1-D2) multiplied by K; in the formula, Delta D represents the radial compression amount of the excircle diameter of the outer metal sheath; D1 represents the inner-circle diameter of the outer metal sheath before the radial compression; D2 represents the excircle diameter of the inner metal sheath; K represents the rubber compression ratio, with the value ranging from 3 to 10 percent. The processing method improves the torsion resistance capacity of the existing anti-earthquake bush, and solves the problem that when in use, the anti-earthquake bush loses anti-earthquake effect and has short service life as the internal tissue of the rubber is destroyed due to the radial torsion force and the axial deviation angle tensile force.

Description

technical field [0001] The invention relates to a method for manufacturing a shockproof bush, in particular to a treatment method for improving the torsion resistance of the shockproof bush. In the torsional anti-vibration system. Background technique [0002] Currently commonly used anti-vibration bushings (also known as rubber bushings), such as figure 1 As shown, it consists of an outer metal sheath (also known as the shell) 1, an inner metal sheath (also called the inner shell) 3, and a rubber layer 2 arranged between the inner metal sheath 3 and the outer metal sheath 1 and elastically connecting them. Because this kind of bushing has good elasticity and damping and shock-isolation performance, it is widely used in the shock-absorbing system of vehicles and construction machinery equipment. The manufacturing method of the above-mentioned anti-vibration bushing is usually to make the outer metal sheath 1 and the inner metal sheath 3 first, and then position the outer m...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a treatment method for improving the torsion resistance of the anti-vibration bushing, the purpose of which is mainly to solve the problems caused by radial torsion and The internal structure of the rubber is damaged due to the axial deflection angle tension, which leads to the problem of cracking and loosening at the connection between the rubber and the inner and outer metal sleeves, which makes the shockproof bush lose the shockproof effect and shorten the service life.
