Oscillating bearing

Abstract

The invention relates to an oscillating bearing which is widely applied to the fields of automobile manufacturing, engineering machinery and the like, and can bear greater loadings. The oscillating bearing comprises an inner ring, an outer ring, a connecting rod, an upper copper ring and a lower copper ring, wherein the inner ring is provided with an outer spherical surface; the outer ring is sleeved on the outer part of the inner ring; the connecting rod is integrated with the outer ring; the upper copper ring and the lower copper ring are positioned between the inner ring and the outer ring; the inner cavity of the upper copper ring and the inner cavity of the lower copper ring are internally provided with arc surfaces which are matched with an outer spherical surface of the inner ring; a storage cavity which can store lubricating oil grease is surrounded among the upper copper ring, the outer ring, the lower copper ring and the inner ring; and the upper copper ring and the lower copper ring are connected with the outer ring. Through the oscillating bearing provided by the invention, the assembling time can be saved greatly, and the assembling difficulty is reduced.

Description

Technical field: [0001] The invention relates to a bearing, in particular to a 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 order. When assembling the above-mentioned joint bearing, first put the copper mesh co...

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
