Outer spherical bearing

Abstract

The invention discloses an outer spherical bearing which comprises a bearing outer ring. An outer ring roller path is arranged on the outer surface of the inner side of the bearing outer ring. A firststeel ball is arranged in the outer ring roller path. A second steel ball is arranged below the first steel ball in the outer ring roller path. A bearing inner ring is arranged in the bearing outer ring. An inner ring roller path is arranged on the outer side of the first steel ball on the outer surface of the bearing inner ring. The outer side of the first steel ball and the outer side of the second steel ball are provided with a retainer respectively. A first sealing ring is arranged between the bearing outer ring and the bearing inner ring. A second sealing ring is arranged on one side ofthe first sealing ring between the bearing outer ring and the bearing inner ring. The outer surface of the bearing outer ring is in the shape of a semi-spherical surface with the radius of 500mm. According to the outer spherical bearing, the service life of the bearing is prolonged, and the replacement and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of bearings, in particular to an outer spherical bearing. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy; the current standard 6203-2RS bearing inner and outer diameters are cylindrical Surface design, this design can not realize the self-aligning effect, when used in the mechanical structure with poor axis alignment between the shaft and the seat hole, the bearing is easy to wear, and the service life is reduced, which brings certain adverse effects to the actual use. To this end, we propose an outer spherical bearing. Contents of the invention [0003] The main purpose of the present invention is to provide an outer spherical bearing, which can effectively solve the problems in the background technology. [0004] In o...
