Detailed description of the invention
Clearer, below in conjunction with this utility model for the purpose making this utility model implement, technical scheme and advantage
Accompanying drawing in embodiment, is further described in more detail the technical scheme in this utility model embodiment.In the accompanying drawings, ad initio
Represent same or similar element to same or similar label eventually or there is the element of same or like function.Described reality
Executing example is a part of embodiment of this utility model rather than whole embodiments.The embodiment described below with reference to accompanying drawing
It is exemplary type, it is intended to be used for explaining this utility model, and it is not intended that to restriction of the present utility model.New based on this practicality
Embodiment in type, the every other enforcement that those of ordinary skill in the art are obtained under not making creation type work premise
Example, broadly falls into the scope of this utility model protection.Below in conjunction with the accompanying drawings embodiment of the present utility model is described in detail.
In description of the present utility model, it is to be understood that term " " center ", " longitudinally ", " laterally ", "front", "rear",
The orientation of the instruction such as "left", "right", " vertically ", " level ", " top ", " end ", " interior ", " outward " or position relationship are for based on accompanying drawing institute
The orientation shown or position relationship, be for only for ease of description this utility model and simplify description rather than instruction or hint indication
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
The restriction of novel protected scope.
It is illustrated in figure 1 retainer schematic diagram of the present utility model, has between outer race 3 and bearing inner ring 2
Retainer 1, the lubricating oil guide surface at retainer 1 arranges two circumferential groove 11 and multiple axial groove 12, and so-called lubricating oil guide surface refers to
Be to maintain the face that frame 1 contacts with bearing inner ring 2, median plane 13 is then perpendicular to the axis of retainer 1 and is positioned at holding
The plane of frame center, circumferential groove 11 is arranged symmetrically in the both sides of median plane 13 and is placed in the outside rolling body opening 21, rolling
Body opening 21 is the hole depositing rolling body 4, and aforesaid outside is then proximate to the direction of retainer both ends of the surface, and axial groove 12 is arranged
Between two circumferential groove 11 and make to interconnect between two circumferential groove 11.
It should be noted that for preferably the lubricating oil between lubricating oil guide surface and bearing inner ring is carried out drain, by hoop
Groove 11 is arranged in parallel to median plane 13.It addition, the axis that axial groove 12 is arranged in parallel to retainer 1 is arranged than axial groove 12
Be more conducive to the circulation of lubricating oil for oblique line or curve, axial groove 12 is uniformly distributed in retainer 1 radial direction.
It addition, the area sum of axial groove 12 and circumferential groove 11 opening part is less than or equal to the one of lubricating oil guide surface area
Half in order to make there are enough contact surfaces between holding lubricating oil guide surface and bearing inner ring 2, in case making the carrying pressure of bearing
Power reduces.
Additionally, circumferential groove 11 and axial groove 12 are half slot, the bottom of groove can be made to deposit incessantly lubricating oil, and then lubricating oil flows to
Notch, promotes lubrication.
Retainer of the present utility model is to solve the inordinate wear problem that retainer 1 lubrication deficiency causes
And oil-free during oil-break, lean conditions, take and slot on the curb girder and crossbeam of retainer 1 for a point oil, the arranging of trapped fuel
Execute, improve the lubrication effect between retainer 1 and lubricating oil guide surface, improve bearing anti-oil-break ability, add axle
Holding the reliability of use, for high DN value, (the i.e. bearing bore diameter of line of slide speed limit DN value (mm) is taken advantage of with axle rotating speed (r/min's)
Long-pending) design of long-life bearing provides sound assurance.
Utilize the circumferential groove 11 offered on retainer 1 and axial groove 12 to carry out effective point of oil, trapped fuel, improve bearing and keep
Lubricant effect between frame 1 and lubricating oil guide surface, effectively reduces retainer abrasion in running, improves bearing and runs
Stability；Simultaneously, it is possible to use the residue lubricating oil in circumferential groove 11 and axial groove 12, bearing is increased anti-by nothing during oil-break
Oil environment oily, lean, improves service life and the reliability of bearing, can reach higher economic effect.
Concrete, the internal diameter lubricating oil guide surface of two curb girders of retainer 1 increases the circumferential groove of complete cycle respectively
11, it is ensured that circumferential groove 11 positional symmetry of both sides, consistent size；The pocket hole crossbeam internal diameter lubricating oil guide surface of retainer increases
Axial groove 12, it is ensured that axial groove 12 is uniform in circumference angle, consistent size；
Time actually used, lubricating oil is from 2 entrance bearings of bearing inner ring, defeated to the circumferential groove 11 of both sides by axial groove 12
Send lubricating oil, it is ensured that the lubricating oil guide surface of retainer 1 has sufficient lubricant effect；When occurring without oil condition, circumferential groove
11 and axial groove 12 can also preserve lubricating oil more, improve without the fretting wear state of bearing during oil condition, raising bearing
Reliability.
Retainer of the present utility model and bearing, by improving the bearing cage structure of lubricant effect, can improve
The lubrication effect of retainer guide surface, improves aircraft bearing anti-oil-break ability, reduces retainer damage probability, thus improves
The reliability of bearing and service life.
The above, optimum detailed description of the invention the most of the present utility model, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with
Described scope of the claims is as the criterion.
