The scheme to continue is produced under this background.
The content of the invention
The technical problems to be solved by the invention be in view of the deficiencies of the prior art with defect and provide a kind of reinforced
Special micro- bearing.
Technical problem solved by the invention can be realized using following technical scheme：
A kind of reinforced micro- bearing of spy, including bearing outer ring and bearing inner race, between the bearing outer ring and bearing inner race
It is provided with steel ball and to keep the retainer of steel ball and dust-proof dustproof cover, it is characterised in that the bearing inner race
The thickness of thickness ratio bearing outer ring is thick, and the quantity of steel ball is 8 and more than eight.
In a preferred embodiment of invention, the diameter of bore of the bearing inner race is 3mm.
In a preferred embodiment of the invention, two outsides of the inner peripheral surface of the bearing outer ring are provided with a sealing surface
With a dustproof cover card access surface, the sealing surface is mutually perpendicular to the dustproof cover card access surface；Set in the dustproof cover card access surface
There is grease seal groove；The dustproof cover is modified form dustproof cover, and the modified form dustproof cover is once struck out using cold-rolled steel sheet
Type, the inner edge of the modified form dustproof cover are the periphery being adapted with the outer circumferential surface of the bearing inner race, and the modified form is prevented
The outer rim of dirt lid is provided with a seal section and a clamping section, and the clamping section is connected with the seal section and is located at the seal section
Outside, the clamping section is mutually perpendicular to seal section, the sealing surface of the inner surface of the seal section and the bearing outer ring
In sealing contact, the clamping section is engaged by clamping with the card access surface on the bearing outer ring.
In a preferred embodiment of the invention, the retainer is molded using cold-pressed steel plate.
As a result of technical solution as above, the beneficial effects of the present invention are：
1. the present invention by varying bearing inner race, the thickness of bearing outer ring, increases the number of steel ball, the footpath of bearing is improved
To bearing capacity and bearing capacity.Additionally by the appropriate thickness that bearing outer ring is thinned, the center-diameter of bearing is increased.Pass through increasing
Add the thickness of bearing inner race, reduce the lasso deflection after bearing assembling.
2. the dustproof cover of the present invention uses inner bead and clamp, and uses cold-pressed steel plate one-pass molding.It is easily installed, improves
The service life of bearing.
The present invention is suitable for high-bearing capacity, long-life, the special micro motor of low noise operating mode.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is attached drawing needed in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, without creative efforts, can be with
Other attached drawings are obtained according to these attached drawings.
Fig. 1 is the structure diagram of an embodiment of the present invention.
Fig. 2 is partial enlarged view of the present invention.
Fig. 3 is top view of the present invention.
Embodiment
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention easy to understand, below into
One step illustrates the present invention.
A kind of reinforced micro- bearing of spy as shown in Figure 1 to Figure 3, including bearing outer ring 100 and bearing inner race 200, bearing
Steel ball 310 is provided between outer ring 100 and bearing inner race 200 and to keep the retainer 300 of steel ball 310 and dust-proof
Dustproof cover 400.
The thickness of the thickness ratio bearing outer ring 100 of the bearing inner race 200 of the present invention is thick, and the diameter of bore of bearing inner race is
3mm, the quantity of steel ball is 8.Improve the radial direction bearing capacity and bearing capacity of bearing.It is thinned additionally by appropriate outside bearing
The thickness of circle 100, increases the diameter of steel ball 310.By increasing the thickness of bearing inner race 200, after reducing bearing assembling
Lasso deflection.
Two outsides of the inner peripheral surface of bearing outer ring 100 are provided with a sealing surface 110 and a dustproof cover card access surface 120, it is close
Front cover 110 is mutually perpendicular to dustproof cover card access surface 120；Grease seal groove 121 is provided with dustproof cover card access surface 120.
The dustproof cover 400 of the present invention uses cold-pressed steel plate one-pass molding, and its inner rim is provided with inner bead 420, dustproof cover 400
Outer rim be provided with seal section 430 and clamping section 410, inner bead 420 rolls to close to the direction of steel ball 310, inner bead 420
Inner surface 421 and the sealing of outer circumferential surface 210 of bearing inner race 200 coordinate.The seal section 430 of 400 outer rim of dustproof cover is to close to steel
