Embodiment 1

[0061] Embodiment 1 of the dust-proof rod-end joint bearing in the present invention: the dust-proof rod-end joint bearing in the present invention can effectively block the intrusion of dust and the like between the inner ring of the bearing and the outer ring of the bearing through the dust-proof cover arranged on it. The working surface of the bearing reduces the wear of the working surface of the bearing and improves the service life of the bearing.

[0062] Such as figure 1 and figure 2 As shown, the main components of the dust-proof rod end joint bearing include a rod end body 10. The rod end body 10 has the same structure as the rod end body of other rod end joint bearings in the prior art. A bearing outer ring 13 is installed in the end hole, and the bearing outer ring 13 is relatively fixedly arranged with the rod end body 10 . A bearing inner ring 14 is movable in the bearing outer ring 13. There is a spherical fitting surface between the bearing outer ring 13 and...

Embodiment 2

[0083] Embodiment 2 of the dust-proof rod end joint bearing in the present invention: the difference from the above embodiment is that the axis of the fixed support ring in this embodiment no longer coincides with the axis of the outer ring of the bearing, and the two are arranged in a manner parallel to the axis , the normal line of the fixed mating surface on the fixed support ring is perpendicular to the axis of the fixed support ring.

Embodiment 3

[0084] Embodiment 3 of the dust-proof rod end joint bearing in the present invention: the difference from the above embodiments is that the fixed mating surface on the fixed support ring in this embodiment is located on the inner peripheral surface of the fixed support ring, and is not limited to The scheme of arranging the fixed mating surface on the outer peripheral surface of the fixed support ring is adopted; or the fixed mating surface is arranged on both the inner peripheral surface and the outer peripheral surface, so as to improve the applicability of the fixed support ring.

Abstract

The invention provides a dustproof rod end joint bearing and a dustproof rod end joint bearing production method. The dustproof rod end joint bearing and the dustproof rod end joint bearing productionmethod can solve the problems of the weak sealing effect and weak reliability caused by easy falling due to influences on a sealing cover by external force in the prior art. The dustproof rod end joint bearing comprises a rod end body provided with a rod end hole, a bearing outer ring, a bearing inner ring, a dustproof cover comprising an inner edge and an outer edge positioned at the inner and outer peripheries of a ring body correspondingly, an inner edge support structure arranged near the bearing inner ring, and an outer edge support structure arranged near the bearing outer ring and comprising a fixed support ring; the fixed support ring is fixed on the rod end body or on the bearing outer ring or between the rod end body and the bearing outer ring, and is clamped and fixed by the rod end body and the bearing outer ring; and fixed matching surfaces are arranged on the inner peripheral surface and / or the outer peripheral surface of the fixed support ring, and are used for being infixed sealing connection with the outer edge of the dustproof cover to form peripheral surface sealing between the dustproof cover and the fixed support ring.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a dust-proof rod-end joint bearing and a production method for the dust-proof rod-end joint bearing. Background technique [0002] Rod end joint bearings, also known as fisheye joints, consist of an inner ring and an outer ring with a sliding spherical surface as the contact surface, and are mainly used in low-speed swinging motions, tilting motions, and rotating motions. When the rod end joint bearing is in use, the inner ring and the outer ring slide relatively. There is no sealing structure on the outer side of the inner ring and the outer ring. The dust in the work site will enter the bearing working surface through the gap between the inner and outer rings, making the bearing Severe abrasive wear on the working face and failure. [0003] In order to solve the problem of the failure of the rod end joint bearing due to abrasive wear, the technicians proposed to add a dust co...
