Novel knuckle bearing

Abstract

The invention relates to a novel knuckle bearing. The novel knuckle bearing comprises an inner ring with an outer spherical surface, an outer ring sleeving the inner ring and a connecting rod integrated with the outer ring. The novel knuckle bearing is characterized by also comprising an upper copper ring and a lower copper ring positioned between the inner ring and the outer ring, wherein inner cavities of the upper copper ring and the lower copper ring are respectively provided with an arc-shaped surface matched with the outer spherical surface of the inner ring; a storage cavity capable of storing lubricating grease is enclosed among the upper copper ring, the outer ring, the lower copper ring and the inner ring; the upper copper ring and the lower copper ring are connected with the outer ring. The novel knuckle bearing has the advantages that one original copper ring is changed into the upper copper ring and the lower copper ring, so that the original copper-mesh composite lubricating strip is saved; since lubricating grease in the storage cavity is adopted for lubricating the inner ring, the related procedure of using a punching machine to shrink the large-opening end of the copper ring at beginning is saved, so that the assembling time is greatly saved.

Description

technical field [0001] The invention relates to a new joint bearing. Background technique [0002] Spherical joint bearings are widely used in automobile manufacturing, engineering machinery and other fields, and can withstand large loads. Such as figure 2 As shown, the existing joint bearing generally includes an outer ring 50, a copper ring 51, a copper mesh composite lubricating strip 54, an inner ring 52, and a connecting rod 55 integrated with the outer ring 50. After the production of the copper ring 51 is completed, the upper end of the copper ring 51 The diameter of the lumen is often larger than the diameter of the lower end lumen, that is, the upper port is larger and the lower port is smaller, see image 3 , the purpose of doing this is to facilitate the loading of the copper mesh composite lubricating strip 54 and the inner ring 52 in the subsequent sequence. When assembling the above-mentioned joint bearing, first put the copper mesh composite lubricating str...

AI Technical Summary

Problems solved by technology

From the assembly process of the above joint bearing, it is not difficult to see that people have used the punching machine twice, and each time the punching machine is used, the processes of positioning, clamping, stamping and disassembly are indispensable. Such operations will definitely increase the assembly time of the joint bearing. In addition, Before using the punching machine for the first time, after the copper mesh composite lubricating strip 54 was installed in the annular groove 56, because the inner cavity diameter at the upper end of the copper ring 51 was greater than the inner cavity diameter at the lower end, the copper mesh composite lubricating strip 54 was easy to move from the large mouth. end slides out, complicating assembly
