Abstract

The invention relates to a lubrication type angular contact knuckle bearing and the processing technology thereof. The lubrication type angular contact knuckle bearing comprises an outer ring 1 and an inner ring 2. The surface where the outer ring 1 and the inner ring 2 are mutually matched is a working surface, the working surface of the outer ring 1 is an inner spherical surface, and the working surface of the inner ring 2 is an outer spherical surface. The outer spherical surface of the inner ring 2 is a smooth outer spherical surface, in order to ensure the working surface of the bearing to be provided with more lubricating oil during working and reduce the abrasion of the bearing, a plurality of reticular lubricating oil grooves 11 which are evenly distributed and are frontally and inversely crossed for 45 to 75 degrees are processed on the inner spherical surface of the outer ring 1 of the bearing, the numbers of the frontal lubricating oil grooves and the inverse lubricating oil grooves are identical, the structure is suitable for the oil bath lubrication operating mode, the lubrication condition of the working surface of the high bearing area is ensured to be particularly improved, therefore to reduce the abrasion of the bearing and enhance the service life of the bearing.

Description

technical field [0001] The invention relates to a bearing and its processing technology, in particular to a lubricated angular contact joint bearing and its processing technology. Background technique [0002] In the existing lubricated angular contact joint bearing, the bearing is composed of an inner ring and an outer ring. The mating surface of the inner and outer rings is the working surface, the working surface of the inner ring is the outer spherical surface, and the working surface of the outer ring is the inner spherical surface. The inner spherical surface of the outer ring usually has two annular intersection lubricating oil grooves. For occasions where the work load is large and the lubrication condition is required to be good, the structure has less oil storage and the lubrication condition is poor. Contents of the invention [0003] The object of the present invention is to solve the problem of less oil storage on the working surface of the existing lubricat...
