Description
Technical field
The present invention relates to technical field of bearings more particularly to a kind of bearing outer rings of good airproof performance.
Background technique
Numerous areas is needed using bearing in the prior art, and bearing is one of component most widely used in mechanical engineering, especially
It is rolling bearing, he is to carry out support rotating part by being in rolling contact between main element, and rolling bearing has friction
Resistance is small, and power consumption is few, starts the advantages that being easy.Rolling bearing is usually to have inner ring, outer ring, rolling element and retainer etc.
Four component compositions, inner ring are used to assemble with axle journal, and outer ring is used to and bearing saddle bore assembly, and usually inner ring is with axle journal time
Turn, outer ring is fixed, but can also with outer ring is turned round and inner ring is motionless or Internal and external cycle turns round simultaneously occasion.As bearing uses
Time it is long, although the frictional force of rolling friction is small, will appear abrasion, especially start moment, influence making for bearing
Use the service life；On the other hand, the sealing problem of bearing is also an extremely important problem, and traditional bearing places the mode of sealing ring
It is not enough securely and inconvenient.
Summary of the invention
The present invention be directed to shortcoming and defect in the prior art, provide it is a kind of with excellent antifriction quality, wearability, from
Lubricity, used time bearing capacity also with higher, good seal performance, dust protection bearing outer ring.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals:
A kind of bearing outer ring of good airproof performance, including outer ring ontology, the inner wall of the outer ring ontology is circumferentially provided with to be rolled for ball
Dynamic roll along trace, the outer ring main body are provided with to place the first installation step of sealing ring in the front-end and back-end of roll along trace
With the second installation step, liner is provided on the roll along trace, is provided on the inner wall of the outer ring ontology for placing liner
Card slot, the material of the outer ring ontology is high-carbon-chromium bearing steel.
As preferred: the material of the outer ring ontology is carburizing bearing steel.
As preferred: it is fillet that first installation step connect side-walls with the second installation step outward.
The invention has the advantages that: structure of the invention designs rationally, by being provided with liner on the inside of bearing outer ring roll along trace,
So that bearing outer ring has excellent antifriction quality, wearability, self-lubrication, used time bearing capacity also with higher；And it sets
The step for the installation sealing ring set, further improves the sealing performance of bearing.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Appended drawing reference: 1, outer ring ontology；2, it pads；11, roll along trace；12, the first installation step；13, the second installation step.
Specific embodiment
Present invention is further described in detail with embodiment with reference to the accompanying drawing.
As shown in Figure 1, a kind of bearing outer ring of good airproof performance, including outer ring ontology 1, the inner wall week of the outer ring ontology 1
To the roll along trace 11 rolled for ball is provided with, the outer ring main body is provided with to place in the front-end and back-end of roll along trace 11
The first installation step 12 and the second installation step 13 of sealing ring are provided with liner 2, the outer ring ontology on the roll along trace 11
The card slot for placing liner 2 is provided on 1 inner wall, the material of the outer ring ontology 1 is high-carbon-chromium bearing steel, by axis
It is provided with liner 2 on the inside of bearing outer-ring roll along trace 11, so that bearing outer ring has excellent antifriction quality, wearability, self-lubrication, uses
When bearing capacity also with higher；And the step of the installation sealing ring of setting, further improve the sealing performance of bearing.
In the present embodiment, the material of the outer ring ontology 1 is carburizing bearing steel, material be carburizing bearing steel (such as
G20Cr2Ni4A), the hardness after Overheating Treatment is generally not less than 60HRC, since these elements of general bearing all can be through
150 DEG C of tempering is crossed, so the hardness of element will not decline usually when the operating temperature of bearing is not higher than 120 DEG C.
In the present embodiment, it is fillet that first installation step 12 connect side-walls with the second installation step 13 outward, if
The fillet set is pressed into sealing ring in seal groove more easily, it is easier to be pressed into place, be also prevented from operator certainly
Scratch is received when being pressed sealing ring.
The present invention has the first installation step 12 and the second erecting bed in the design of the two sides of the inner wall roll along trace 11 of outer ring ontology 1
Rank 13, first installation step 12 and the second installation step 13 can install sealing ring, and the sealing ring being arranged in step can
So that the sealing performance of entire bearing greatly improves, so that the bearing of composition is oil-proof, dust protection.
The above is only a preferred embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to the present invention
Limitation.
