Three-sliding radial spherical plain bearing

Abstract

The invention provides a three-sliding radial spherical plain bearing. The three-sliding radial spherical plain bearing is characterized in that an inner ring with an outer spherical surface is sleeved in an outer ring with an inner spherical surface, the inner ring is in spherical fit with the outer ring, the three-sliding radial spherical plain bearing is characterized by being provided with a plurality of section planes which are arranged at equal intervals and are vertical to the axis of the inner ring, and a plurality of oil storage holes which are uniformly distributed along the circumference are formed in a circular section intersecting line of each section plane and the inner hole wall of the inner ring; and a driving end is fixedly connected with the outer ring, the oil storage holes are filled with lubricating grease, a shaft penetrates through the inner ring and is in clearance fit with an inner hole of the inner ring, and a lubricating oil film is formed between the inner hole of the inner ring and the shaft. When the radial spherical plain bearing is used, the radial spherical plain bearing is prevented from losing efficacy due to jamming, and the service life of the bearing is prolonged.

Description

technical field [0001] The invention relates to a centripetal joint bearing structure. Background technique [0002] The radial joint bearing is a kind of spherical sliding bearing. The inner ring with outer spherical surface is sleeved in the outer ring with inner spherical surface. The inner ring and outer ring are spherically matched, and the shaft passes through the inner ring and fits with the inner hole of the inner ring. Its typical features are the ability to withstand heavy loads and the ability to self-align. [0003] Problems existing in the radial joint bearing of the existing structure: [0004] 1: The shaft and inner ring often cause the bearing to be stuck due to too much axial friction. [0005] 2: The friction between the inner ring and the outer ring is too large to cause the jamming and the failure of the bearing function. [0006] 3: The service life of the bearing needs to be further improved. Contents of the invention [0007] The invention provid...
