Abstract
The purpose of this utility model is to provide a kind of arc-shaped bearing cage, the technical issues of being well clamped to roller for solution and preferably radiate.A kind of arc-shaped bearing cage, including outer ring plate, inner ring plate and card adapter plate；The card adapter plate uses circular groove plate, and between the outer ring plate and inner ring plate, card adapter plate is equipped with multiple pocket holes for being clamped roller.Utility model advantageous effect：This bearing cage can form point lock by pocket hole, the first fore shaft and the second fore shaft to roller, can be formed to roller and keep effect well, while be conducive to the heat dissipation in the roller course of work.
Description
Technical field
The utility model is related to bearing cage technical field, specifically a kind of arc-shaped bearing cage.
Background technology
Bearing cage is the important component for being clamped bearing roller, for some Special use occasions.Bearing is kept
Device not only will be to stronger intensity, supporting the reliable holding of roller with formation；Meanwhile it is excellent to need requirement to have roller
Good heat dissipation performance.
Utility model content
The purpose of this utility model is to provide a kind of arc-shaped bearing cage, for solve well to be clamped roller with
And the technical issues of preferably radiating.
The technical solution adopted by the utility model to solve its technical problems is that：
A kind of arc-shaped bearing cage, including outer ring plate, inner ring plate and card adapter plate；The card adapter plate is using arc-shaped
Concave-board, between the outer ring plate and inner ring plate, card adapter plate is equipped with multiple pocket holes for being clamped roller.
Further, the two sides of the card adapter plate is respectively arc convex and arc-shaped concave.
Further, the arc convex forms the first buckling groove with inner ring plate, card adapter plate；Outer ring plate and inner ring plate it is outer
End is tilted to the inside of first buckling groove respectively, forms the first fore shaft.
Further, the arc-shaped concave forms the second buckling groove with inner ring plate, card adapter plate；Outer ring plate and inner ring plate it is outer
End is tilted to the inside of second buckling groove respectively, forms the second fore shaft.
Further, the pocket hole is interference fitted with roller.
The effect provided in utility model content is only the effect of embodiment, rather than whole effects that utility model is all
Fruit, has the following advantages that in above-mentioned technical proposal or advantageous effect：
This bearing cage can form point lock by pocket hole, the first fore shaft and the second fore shaft to roller, can be to roller
It is formed and keeps effect well, while being conducive to the heat dissipation in the roller course of work.

Fig. 2 be the utility model embodiment in card adapter plate arc-shaped concave outwardly when overall structure diagram；
Fig. 3 is the schematic top plan view that the utility model embodiment is clamped after roller；
In figure：1. outer ring plate；2. inner ring plate；3. card adapter plate；4. pocket hole；5. arc convex；6. arc-shaped concave；7. the first lock
Mouthful；8. the second fore shaft；9. roller.
Specific implementation mode
In order to clearly illustrate the technical characterstic of this programme, below by specific implementation mode, and its attached drawing is combined, to this
Utility model is described in detail.It should be noted that illustrated component is not drawn necessarily to scale in the accompanying drawings.The utility model
It is omitted to known assemblies and known technology description, to avoid the utility model is unnecessarily limiting.
As shown in Figures 1 to 3, a kind of arc-shaped bearing cage, it is whole to use cirque structure, including outer ring plate 1, inner ring
Plate 2 and card adapter plate 3；The card adapter plate 3 uses circular groove plate, between the outer ring plate 1 and inner ring plate 2, card
Fishplate bar 3 is equipped with multiple pocket holes 4 for being clamped roller 9.
The two sides of shown card adapter plate 3 is respectively arc convex 5 and arc-shaped concave 6, and 5 height of arc convex is less than outer ring plate 1
With the height of inner ring plate 2, the arc convex 5 and the outer ring plate 1, inner ring plate 2 form for being clamped 9 side of roller
One buckling groove；The outer end of outer ring plate 1 and inner ring plate 2 is respectively to being tilted a certain angle on the inside of first buckling groove, to be formed
The first fore shaft 7 for being clamped roller.The junction of first buckling groove and the outer ring plate 1 and inner ring plate 2, is adopted respectively
Prevent the stress of corner from excessively concentrating to improve structural strength with rounded corner.The arc-shaped concave 6 and the outer ring plate
1, inner ring plate 2 forms the second buckling groove for being clamped 9 other side of roller；The outer end of outer ring plate 1 and inner ring plate 2 is respectively to described
It is tilted a certain angle on the inside of second buckling groove, to form the second fore shaft 8 for being clamped roller 9.Second buckling groove with
The junction of the outer ring plate 1 and inner ring plate 2, is respectively adopted rounded corner, to improve structural strength, prevents the stress of corner
Excessively concentrate.4 diameter of pocket hole is slightly less than by the diameter of clamping roller 9, in this way when roller 9 and pocket hole 4 coordinate, pocket hole 4
Upper and lower ends and roller formed and be interference fitted.
The advantages of the utility model embodiment, is：This bearing cage can pass through pocket hole 4, the first fore shaft 7 and second
Fore shaft 8 forms point lock to roller 9, can be formed to roller 9 and keep effect well, while is conducive in 9 course of work of roller
Heat dissipation.
It is the known technology of those skilled in the art in addition to the technical characteristic described in specification.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but not to this practicality newly
The limitation of type protection domain, on the basis of technical solutions of the utility model, those skilled in the art need not pay creativeness
The various modifications or changes that can make of labour it is still within the protection scope of the present utility model.
