Further, the shock absorption layer is a rubber layer.

Further, the shock absorption layer is solidified on the attachment surface of the bearing inner ring.

Furthermore, the resetting structure comprises a groove formed in the damping layer and a protruding portion arranged on the outer side face of the bearing inner ring, the protruding portion is located in the groove, and when the bearing inner ring swings, the protruding portion swings correspondingly in the groove.

Furthermore, the groove surface of the groove is a spherical surface, and the outer side surface of the convex part is also a spherical surface.

Further, the self-resetting radial spherical plain bearing is subjected to integral vulcanization treatment.

In conclusion, the utility model has the following beneficial effects:

1. the damping layer is arranged between the bearing outer ring and the bearing inner ring and made of soft rubber, so that the damping layer has good shock absorption performance, and all the parts are vulcanized to further increase elasticity and tensile modulus and prolong the service life as the parts such as the bearing outer ring and the bearing inner ring move frequently.

2. The bulge and the groove are both arranged into spherical surfaces, so that the bearing inner ring can swing, and after the swing is completed, the quick reset can be completed along the spherical surfaces, and the self-reset function with large force is achieved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the following detailed description of the present invention is provided with reference to the accompanying drawings and the detailed description. The advantages and features of the present invention will become more apparent from the following description. It is to be noted that the drawings are in a very simplified form and are all used in a non-precise scale for the purpose of facilitating and distinctly aiding in the description of the embodiments of the present invention. To make the objects, features and advantages of the present invention comprehensible, reference is made to the accompanying drawings. It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for matching with the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the implementation conditions of the present invention, so that the present invention has no technical significance, and any structural modification, ratio relationship change or size adjustment should still fall within the scope of the present invention without affecting the efficacy and the achievable purpose of the present invention.

Example (b):

a self-resetting radial spherical plain bearing is shown in figure 1 and comprises a steel sleeve 1, a bearing inner ring 3 and a bearing outer ring 2, wherein the steel sleeve 1 is arranged in a hollow mode, the bearing inner ring 3 and the bearing outer ring 2 are installed in an inner cavity of the steel sleeve 1, and the bearing inner ring 3 swings freely. The outer side of the steel sleeve 1 is also provided with an integrally formed connecting rod, and the joint bearing can be arranged in a braking system through the connecting rod.

Further, as shown in fig. 1 and 2, the outer side surface of the bearing outer ring 2 is attached to the inner wall of the steel bushing 1, and chamfers are arranged on two side surfaces of the outer side surface of the bearing outer ring 2, wherein the angle of the chamfers is 15 degrees, so that the bearing outer ring 2 can be smoothly installed in the steel bushing 1, and the damage caused by collision of the edges can be reduced as much as possible.

Further, as shown in fig. 1 and 2, a damping layer 4 is disposed between the bearing inner ring 3 and the bearing outer ring 2, and the damping layer 4 is solidified on the attachment surface of the bearing inner ring 3. The shock absorbing layer 4 is preferably a rubber layer which has good elasticity and plasticity, and when the shock absorbing layer 4 works, the shock absorbing layer can absorb shock generated by the action of the components, so that the shock absorbing effect is improved. The self-resetting radial spherical plain bearing is subjected to integral vulcanization treatment, so that the elasticity and the tensile modulus are further increased. Because the shock-absorbing layer 4 is adapted to the working state that the bearing outer ring 2, the bearing inner ring 3 and other parts frequently move and are in the working state of high load, all the parts are vulcanized and strengthened, and the service life of the shock-absorbing layer 4 is prolonged.

Further, as shown in fig. 2, a resetting structure is arranged between the bearing inner ring 3 and the bearing outer ring 2, the resetting structure includes a groove 41 formed on the damping layer 4 and a protrusion 31 arranged on the outer side surface of the bearing inner ring 3, and the protrusion 31 is embedded in the groove 41. The groove surface of the groove 41 is a spherical surface, the outer side surface of the protruding part 31 is also set to be a spherical surface, when the bearing inner ring 3 swings, meanwhile, the protruding part 31 rotates in the groove 41, due to the effect of the spherical surface, the bearing inner ring 3 has a tendency of rotating and resetting, and when the influence of external force is removed, the bearing inner ring 3 can automatically reset.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
