Abstract
The invention discloses an easy-to-lubricate bearing, which comprises an outer ring, an inner ring and a cylindrical roller that are assembled together. The arc surface of the cylindrical roller is provided with a spiral groove along the axial direction, two end faces of the cylindrical roller are provided with mounting blind holes, two annular ribs extend respectively from two end faces of the inner ring along the radial direction, two sides corresponding to the two annular ribs are provided with support pillars uniformly along the circumferential direction, and the support pillars on the two annular ribs are in one-to-one correspondence, the cylindrical roller is installed between the two annular ribs of the inner ring, and the support pillars on the annular ribs are correspondingly mounted in the mounting blind holes on the two end faces of the cylindrical roller respectively. The outer surface of the cylindrical roller is provided with the spiral groove, on the one hand, lubricating oil and grease can be effectively stored, and on the other hand, along with the rotation of the roller, the spiral groove can bring lubricating grease to lubrication places between all the components, so that the overall lubrication effect of the bearing is greatly improved.
Description
Technical field
The invention belongs to technical field of bearings, particularly relate to a kind of bearing being convenient to lubricate.
Background technique
As everyone knows, bearing is made up of outer ring, inner ring, retainer and rolling element, and the key factor affecting bearing working life is frictional loss.Friction between rolling element and Internal and external cycle, the friction between rolling element and retainer and the friction etc. between inner ring and axle, these frictions all can the whole service life of loss bearing, existing remission method is by adding lubricant oil, lubricating grease etc. in bearing, but the equipped sealing between each parts of bearing is higher, therefore, lubricating oil filling or lubricating grease enter inside bearing, comparatively difficulty, and easily the lubricant oil do not entered in bearing, lubricating grease are dripped on ground and cause waste.
Summary of the invention
In order to solve the problem, the object of this invention is to provide a kind of bearing being convenient to lubricate, this bearing is convenient to add lubricant oil, lubricating grease etc. to Bearing inner in the course of the work and is lubricated, and can substantially increase the working life of bearing.
For achieving the above object, the present invention adopts following technological scheme:
A kind of bearing being convenient to lubricate, comprise the outer ring of matched together, inner ring and cylindrical roller, the arc-shaped surface of described cylindrical roller is axially arranged with helical groove along it, the both ends of the surface of cylindrical roller are provided with installing blind, the both ends of the surface of described inner ring radially extend an annular rib respectively, the bi-side that two annular ribs are corresponding are along the circumferential direction laid with supporting post, and the supporting post one_to_one corresponding on two annular ribs, described cylindrical roller is installed between two annular ribs of inner ring, and two annular rib upper support columns are corresponding is respectively installed in the installing blind of cylindrical roller both ends of the surface.
Further, the center of described cylindrical roller is axially arranged with hollow lumen along it, and helical groove is communicated with the hollow lumen of cylindrical roller by some through holes that its bottom surface is offered.
Owing to adopting technological scheme as above, the present invention has following superiority:
The present invention arranges helical groove by the outer surface of cylindrical roller, can effectively store lubricant oil, fat on the one hand, on the other hand along with the rotation of roller, lubricant grease can be taken to the place of lubricating between each parts by helical groove, and the overall lubrication effect of bearing is substantially increased; In addition, due to the outer surface of cylindrical roller offering helical groove, so make the area of contact of cylindrical roller and inside and outside circle greatly reduce, decrease frictional loss.

Fig. 2 is the structural representation of inner ring in the present invention;
In Fig. 1: 1-cylindrical roller; 2-helical groove; 3-installing blind; 4-inner ring; 5-annular rib; 6-supporting post.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further detailed explanation.
As Fig. 1, shown in 2, a kind of bearing being convenient to lubricate, comprise the outer ring of matched together, inner ring and cylindrical roller, the arc-shaped surface of described cylindrical roller 1 is axially arranged with helical groove 2 along it, the both ends of the surface of cylindrical roller 1 are provided with installing blind 3, the both ends of the surface of described inner ring 4 radially extend an annular rib 5 respectively, the bi-side that two annular ribs 5 are corresponding are along the circumferential direction laid with supporting post 6, and supporting post 6 one_to_one corresponding on two annular ribs, described cylindrical roller 1 is installed between two annular ribs 5 of inner ring, and two annular rib 5 upper support columns 6 are corresponding is respectively installed in the installing blind 3 of cylindrical roller 1 both ends of the surface.
The center of described cylindrical roller 1 is axially arranged with hollow lumen along it, and helical groove is communicated with the hollow lumen of cylindrical roller by some through holes that its bottom surface is offered; After adding lubricant oil to Bearing inner, lubricant oil flow in hollow lumen by the through hole on helical groove, can reduce outflow of lubrication oil Bearing inner largely, substantially prolongs the working life of bearing.
The present invention arranges helical groove by the outer surface of cylindrical roller, can effectively store lubricant oil, fat on the one hand, on the other hand along with the rotation of roller, lubricant grease can be taken to the place of lubricating between each parts by helical groove, and the overall lubrication effect of bearing is substantially increased; In addition, due to the outer surface of cylindrical roller offering helical groove, so make the area of contact of cylindrical roller and inside and outside circle greatly reduce, decrease frictional loss.
Claims (2)
1. be convenient to the bearing of lubrication for one kind, comprise the outer ring of matched together, inner ring and cylindrical roller, it is characterized in that: the arc-shaped surface of described cylindrical roller is axially arranged with helical groove along it, the both ends of the surface of cylindrical roller are provided with installing blind, the both ends of the surface of described inner ring radially extend an annular rib respectively, the bi-side that two annular ribs are corresponding are along the circumferential direction laid with supporting post, and the supporting post one_to_one corresponding on two annular ribs, described cylindrical roller is installed between two annular ribs of inner ring, and two annular rib upper support columns are corresponding is respectively installed in the installing blind of cylindrical roller both ends of the surface.
2. the bearing being convenient to lubricate according to claim 1, it is characterized in that: the center of described cylindrical roller is axially arranged with hollow lumen along it, helical groove is communicated with the hollow lumen of cylindrical roller by some through holes that its bottom surface is offered.
