Abstract
The utility model discloses an improved structure of a radial spherical plain bearing. The improved structure comprises an inner ring and an outer ring which are mutually engaged; the inner ring is provided with an outer spherical surface; the outer ring is provided with an inner spherical surface; the outer spherical surface of the inner ring is a smooth surface; and two mutually intersected closed-loop grooves are arranged on the inner spherical surface of the outer ring. By adopting the technical scheme, the improved structure has the advantages that the outer spherical surface of the inner ring is the smooth surface; the two mutually intersected closed-loop grooves are arranged on the inner spherical surface of the outer ring; and the improved structure is convenient in processing and comparatively high in production efficiency as only two closed-loop grooves are arranged.
Description
Technical field
The utility model relates to a kind of bearing, specifically is a kind of plain radial bearing.
Background technique
Plain radial bearing is a kind of sliding bearing of special construction.Its structure is simpler than rolling bearing, it mainly is made up of an inner ring and the outer ring by inner ball surface by outer spherical surface, can bear bigger load, according to its different types and structure, can bear radial load, axial load or radially, axial simultaneous joint load.Be widely used in the engineering hydraulic jack, forging machine tool, engineering machinery, automation equipment, automobile absorber, water conservancy machinery, rocking apparatus, industries such as vibratory equipment.This plain radial bearing is abound with the more shallow oil groove of the degree of depth that distributes as net shape on the outer spherical surface of its inner ring, grease is sent into by this oil groove and is lubricated during use.Owing to be abound with latticed oil groove on the outer spherical surface of inner ring, processing is trouble comparatively, and manufacturing efficiency is lower.
The model utility content
The purpose of this utility model provides a kind of easy to process, the structure-improved of the plain radial bearing that manufacturing efficiency is higher.
The technical solution of the utility model is such: the structure-improved of plain radial bearing comprises inner ring with outer spherical surface that matches and the outer ring with inner ball surface; The outer spherical surface of above-mentioned inner ring is a smooth surface, offers two closed loop oil grooves that intersect on the inner ball surface of above-mentioned outer ring.
Above-mentioned every closed loop oil groove is all around one week of inner ball surface of above-mentioned outer ring.
The point of intersection of above-mentioned two closed loop oil grooves is positioned on the largest circumference of inner ball surface of above-mentioned outer ring.
After adopting such scheme, the beneficial effects of the utility model are: the outer spherical surface of inner ring is a smooth surface, offers two closed loop oil grooves that intersect on the inner ball surface of outer ring, owing to have only two closed loop oil grooves, easy to process, manufacturing efficiency is higher.
