Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments:

the utility model provides a joint bearing's concrete embodiment:

as shown in fig. 1 to 3, a joint bearing comprises an outer ring 1 with an inner spherical surface and an inner ring 2 with an outer spherical surface, wherein the inner spherical surface of the outer ring 1 is provided with an annular caulking groove 3, the notch of the annular caulking groove 3 faces the outer spherical surface of the inner ring 2, a wear-resistant lining plate 4 is embedded in the annular caulking groove 3, a clamping groove facing the outer spherical surface of the inner ring 2 is formed in the wear-resistant lining plate 4, and a rolling ball 5 is clamped in the clamping groove. When the knuckle bearing is used, frictional extrusion force generated in the relative rotation process of the inner ring 2 and the outer ring 1 is transferred to the rolling balls 5 of the inner ring 2 and the wear-resistant lining plate 4, not only is the frictional extrusion transferred, but also the surface friction between the inner ring 2 and the outer ring 1 is transferred to the rolling friction between the inner ring 2 and the rolling balls 5, the rolling friction force is effectively absorbed by the rolling balls 5, even if the rolling friction force is large, and the wear-resistant lining plate 4 is damaged, the wear-resistant lining plate 4 can be taken out of the annular embedded groove 3, the rolling balls 5 or a new wear-resistant lining plate 4 can be replaced, the outer ring 1 is effectively protected, the wear-resistant lining plate does not need to be replaced even if being used for a long time, and the service life of the knuckle bearing is effectively prolonged.
