The centripetal joint bearing provided by the invention is mainly characterized by comprising an outer ring and an inner ring, wherein the external surface of the outer ring is provided with an outer ring outer diameter lubrication groove and two symmetrical outer ring lubricating oil holes, the outer spherical surface of the inner ring is provided with an inner ring outer spherical surface lubrication groove, which is perpendicular to the center line of an inner hole, and four uniformly distributed inner ring lubricating oil holes, the inner diameter surface of the inner ring is provided with two inner ring inner diameter spiral lubrication grooves, and the two inner ring inner diameter spiral lubrication grooves are intersected with the inner ring lubricating oil holes. The centripetal joint bearing provided by the invention has the characteristics of increase of oil storage in an inner diameter surface groove, reduction of abrasion and clamping stagnation between the inner diameter and a shaft, prolongation of the service life of the bearing, improvement of process operability, enhancement of product quality and working efficiency, etc. and is mainly applicable to centripetal joint bearings which are in need of good lubrication conditions, an automobile brake drum, a low speed and heavy load.
Description
Technical field
The invention belongs to plain radial bearing technical field, be specifically related to two spiral fluted plain radial bearings of a kind of bearing bore diameter band.
Background technique
In existing plain radial bearing, for sufficient lubrication, at inside diameter surface, arrange several perpendicular to the lubricated arc groove of end face, lubrication groove oil storage is few like this, sufficient not evenly to the fuel feeding on internal diameter and axle sliding contact surface, the easy to wear and clamping stagnation of internal diameter and axle, can not meet automobile brake drum needs, such is perpendicular to the lubricated arc groove of end face, emery wheel and the interrupted penetration of a cutting tool of workpiece groove when grinding, grinding wheel spindle produces resiliently deformable, and groove limit mouth size is large, reject rate is high, and manufacturability is poor.In addition, processing needs special device, and work efficiency is low.
Summary of the invention
Object of the present invention is exactly for above-mentioned deficiency, to provide a kind of and increase oil storage in inside diameter surface groove, reduce wearing and tearing between internal diameter and axle and clamping stagnation, raising bearing working life, improve technique operability, improve the quality of products and the plain radial bearing of the threaded groove of internal diameter of work efficiency.
Technical solution of the present invention is: the plain radial bearing of the threaded groove of a kind of internal diameter, comprise outer ring and inner ring, outer ring outer surface width centre bit is equipped with Yi Tiao outer ring external diameter lubrication groove and two symmetrical outer ring oilholes, inner ring outer spherical surface width centre bit be equipped with one with the perpendicular inner ring outer spherical surface lubrication groove of inner hole centreline and four uniform inner ring oilholes, it is characterized in that: inner ring internal diameter screw lubrication groove is set on inner ring aperture surface, and this inner ring internal diameter screw lubrication groove and inner ring oilhole intersect.
Inner ring internal diameter screw lubrication groove described in technical solution of the present invention is two.
Two inner ring internal diameter spiral fluted slot pitches described in technical solution of the present invention are 16-18mm; Inner ring internal diameter spiral fluted groove width is that 3.8-4.3mm, groove depth are 0.8-1mm.
Outer ring inner ball surface described in technical solution of the present invention is provided with outer ring inner ball surface screw lubrication groove.
The groove width of the outer ring inner ball surface screw lubrication groove described in technical solution of the present invention is that 3.8-4.3mm, groove depth are 0.8-1mm.
The invention has the beneficial effects as follows, screw lubrication groove can store a certain amount of lubricating grease, arrives more full and uniform wearing and tearing and the clamping stagnation having reduced between internal diameter and axle of oil film of internal diameter and axle contact surface, thereby improves the working life of bearing.In addition, while reworking, can make within a short period of time bearing and working surface reach good lubricating status at every turn.Improve technique operability, the penetration of a cutting tool of grinding strip spiral chute internal diameter is consistent, and grinding wheel spindle does not produce resiliently deformable, improves the quality of products and work efficiency.The present invention is mainly applicable to require that lubrication state is good, the plain radial bearing of automobile brake drum, low speed, heavy duty.
Accompanying drawing explanation
Fig. 1 is the structural representation of internal diameter band spiral fluted plain radial bearing of the present invention.
Mark in figure: 1-outer ring, external diameter lubrication groove ,1-2 outer ring, 2-inner ring ,1-1 outer ring oilhole, 2-1 inner ring outer spherical surface lubrication groove, 2-2 inner ring oilhole, 2-3 inner ring internal diameter screw lubrication groove.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, the present invention is comprised of outer ring 1 and inner ring 2, and outer ring 1 internal surface and inner ring 2 outer surfaces are sliding contact surface, and outer ring 1 internal surface is inner ball surface, inner ring 2 outer surfaces are outer spherical surface, and outer ring 1 external diameter width centre bit is equipped with annular outer ring external diameter lubrication groove 1-1Ji outer ring oilhole 1-2; Inner ring 2 outer spherical surface width centre bits be equipped with one with perpendicular annular inner ring outer spherical surface lubrication groove 2-1 and the inner ring oilhole 2-2 of inner hole centreline, on inner ring 2 internal diameters, have inner ring internal diameter screw lubrication groove 2-3, this inner ring internal diameter screw lubrication groove 2-3 intersects in inner ring oilhole 2-2.Article two, the slot pitch of inner ring internal diameter spiral chute 2-3 is 16-18mm; The groove width of inner ring internal diameter spiral chute 2-3 is that 3.8-4.3mm, groove depth are 0.8-1mm.
Adopt the plain radial bearing of this structure to have two kinds of lubricating systems, the one, 1 outer ring oilhole 1-2 enters inner ring 2 outer surface inner ring outer spherical surface lubrication groove 2-1 and screw lubrication groove 2-3 through outer ring from shell aperture, to inject lubricating grease, through these lubrication grooves, lubricating grease is delivered to the sliding contact surface (working surface) of inside and outside circle 2,1, on inner ring 2, inner ring oilhole 2-2 enters the matching surface of inner ring and axle again, lubricated to the matching surface of inner ring and axle.Another kind of mode is lubricating grease to be injected into the matching surface of axle and inner ring from axle oil inlet hole, the working surface that makes lubricating grease arrive Internal and external cycle through inner ring oilhole 2-2 arrival inner ring outer spherical surface lubrication groove 2-1, inner ring internal diameter screw lubrication groove 2-3 is lubricated, and lubricating grease also can arrive by outer ring oilhole 1-2 capable the lubricating of matching surface of outer ring and shell aperture.Plain radial bearing is mainly the joint shaft bearing that bears radial load, and plain radial bearing of the present invention is applicable to require lubrication state good, and the mechanical mechanism of low speed, heavy duty can be sooner, lubricated more fully.
As another embodiment of the present invention, outer ring inner ball surface also can be provided with outer ring inner ball surface screw lubrication groove, and oil storage is more like this, lubricated more full and uniform.The groove width of outer ring inner ball surface screw lubrication groove is that 3.8-4.3mm, groove depth are 0.8-1mm.
