The technical problem to be solved by the utility model is in view of the deficiencies of the prior art with defect and provide it is a kind of plus
The special micro- bearing of strong type.
Following technical scheme may be used to realize in the technical issues of the utility model is solved：
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 the retainer for keeping steel ball and dust-proof dustproof cover, which is characterized in that the bearing inner race
Thickness is thicker than the thickness of bearing outer ring, and the quantity of steel ball is 8 and eight or more.
In a preferred embodiment of utility model, the diameter of bore of the bearing inner race is 3mm.
In a preferred embodiment of the utility model, to be provided with one close in two outsides of the inner peripheral surface of the bearing outer ring
Cover and a dustproof cover card access surface, the sealing surface are mutually perpendicular to the dustproof cover card access surface；In the dustproof cover card access surface
It is provided with grease seal slot；The dustproof cover is modified form dustproof cover, and the modified form dustproof cover is once rushed using cold-rolled steel sheet
Molded, the inner edge of the modified form dustproof cover is periphery compatible with the peripheral surface of the bearing inner race, the improvement
The outer rim of type dustproof cover is provided with a seal section and a clamping section, and the clamping section connect with the seal section and is located at described close
The outside of section is sealed, the clamping section is mutually perpendicular to seal section, and the inner surface of the seal section is close with the bearing outer ring
Cover is in sealing contact, and the clamping section is engaged by clamping with the card access surface on the bearing outer ring.
In a preferred embodiment of the utility model, the retainer is molded using cold-pressed steel plate.
As a result of technical solution as above, the beneficial effects of the utility model are：
1. the utility model increases the number of steel ball, improves bearing by change bearing inner race, the thickness of bearing outer ring
Radial bearing capacity and bearing capacity.Additionally by the appropriate thickness that bearing outer ring is thinned, the center-diameter of bearing is increased.It is logical
The thickness for increasing bearing inner race is crossed, the lasso deflection after bearing assembly is reduced.
2. the dustproof cover of the utility model uses inner bead and clamp, and uses cold-pressed steel plate one-pass molding.It is easily installed,
Improve the service life of bearing.
The utility model be suitable for high-bearing capacity, the long-life, low noise operating mode special micro motor.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only

Under, other drawings may also be obtained based on these drawings.
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model.
Fig. 2 is the utility model partial enlarged view.
Fig. 3 is the utility model vertical view.
Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
The utility model is expanded on further in face.
The reinforced micro- bearing of spy of one kind 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 bearing inner race 200 of the utility model is thicker than the thickness of bearing outer ring 100, the diameter of bore of bearing inner race
Quantity for 3mm, steel ball is 8.Improve the radial bearing capacity and bearing capacity of bearing.Bearing is thinned additionally by appropriate
The thickness of outer ring 100 increases the diameter of steel ball 310.By increasing the thickness of bearing inner race 200, after reducing bearing assembly
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
Cover 110 is mutually perpendicular to dustproof cover card access surface 120；Grease seal slot 121 is provided in dustproof cover card access surface 120.
The dustproof cover 400 of the utility model uses cold-pressed steel plate one-pass molding, and inner rim is provided with inner bead 420, dust-proof
The outer rim of lid 400 is provided with seal section 430 and clamping section 410, and inner bead 420 is rolled to close to the direction of steel ball 310, inner bead
