Embodiment 1

[0019] figure 1 A specific embodiment of the present invention is given, and it can be seen from the accompanying drawings that the present invention is a ball joint type rubber elastic element, including a metal inner sleeve (or mandrel) 1, a metal outer sleeve 2, and an elastic rubber body 4 , the metal stopper 3, the elastic rubber body 4 and the metal inner sleeve (or mandrel) 1 are vulcanized into an elastic body, and the elastic body is pressed into the metal outer sleeve 2; Edge; a metal stopper 3 is pressed on the outer edge of the elastic rubber body 4, and the metal stopper 3 is wrapped inwardly by the flanging of the metal jacket 2, so that the metal stopper 3 compresses the elastic rubber body to form a pre-compressive stress. There are two metal stoppers 3 , and one side of the elastic rubber body 4 in the axial direction.

[0020] The production of spherical hinge rubber elastic elements is as follows: image 3 shown. The specific assembly steps are as follows...

Embodiment 2

[0025] The structure of the second embodiment is similar to that of the first embodiment, except that the number of metal stoppers is changed from two to one, and only one is provided on either side of the elastic rubber body 4 in the axial direction. In this way, compared with the first embodiment, the axial precompression stress is adjusted, so that the axial stiffness is further reduced.

Abstract

A method for assembling spherical hinge rubber elastic element comprises the following steps: pressing an elastic body composed of elastic rubber body and metal internal sleeve into metal outer sleeve, then pressing the metal holder into the metal outer sleeve, turning the side of metal outer sleeve, forcing the metal holder to compress the elastic rubber body during the process of turning side so as to realize the pre-compression stress of elastic rubber body of spherical hinge rubber elastic element. The spherical hinge rubber elastic element comprises a metal internal sleeve, a metal outer sleeve, an elastic rubber body and a metal holder. The elastic rubber body and metal internal sleeve are vulcanized to be elastic body, which is pressed in the metal outer sleeve. A turned-over edge is on the metal outer sleeve; the metal holder is pressed at the outer edge of the elastic rubber body and covered by the turned-over edge of the metal outer sleeve. The advantage of the invention is that the radial and axial pre-compression stresses can be changed, so the radial and axial stiffness ratio can be regulated flexibly.

Description

technical field [0001] The invention belongs to a method for assembling vibration-damping parts and products, in particular to a method for making and assembling ball-joint-type rubber elastic components and products; it is mainly used in rubber elastic components for bogies of various locomotives and vehicles. It can be applied to any vibration-damping elastic connection parts such as construction machinery. Background technique [0002] Ball joint type rubber elastic element is a commonly used rubber-metal composite damping element, which can be widely used in various vibration damping places, especially in the bogies of rolling stock. Among them, the most common application is the three-piece structure (metal jacket + rubber + mandrel), and this structure has some characteristics, but also has disadvantages. The characteristic is that their performance can basically meet the use of various working conditions. The disadvantage is that the rubber elastic elements of the ba...
