Problems solved by technology

[0002] The existing spherical plain bearing is mainly composed of an inner ring and an outer ring, which can bear a relatively large load. Because the sliding contact area of ​​the inner ring and the outer ring is large, the friction between the inner ring and the outer ring of the bearing is relatively large, and it is easy to be damaged. Moreover, the existing joint bearing connection structure is easy to cause the connecting parts to fall off during application. Because it is not easy to disassemble, it is very inconvenient for maintenance. After one of the components of the shutdown bearing is damaged, the entire joint bearing is usually replaced together. wasted resources

Abstract

The present invention discloses a hydraulic special joint bearing comprising an inner ring and an outer ring. The inner ring is located within the outer ring. Sealing rings are disposed at junctions of both sides of the inner ring and the outer ring, respectively. The outer ring comprises an upper end cover and a lower end cover. Fixed lugs are disposed at two ends of the joint of the upper end cover and the lower end cover, respectively. Corresponding threaded holes are formed in the fixed lugs. The upper end cover is fixedly connected with the lower end cover by means of a bolt. Two oil passages are formed in an outer surface in the circumferential direction of the inner ring. An oil filling hole is formed in the upper end cover. The oil filling hole is a herringbone hole, and communicates with the oil passages. The oil passages are capable of reducing the degree of friction between the inner ring and the outer ring, convenient for lubricating oil to flow within the joint bearing to reduce the attrition of the joint bearing, and also convenient for later maintenance and repair of the joint bearing.
