Description
Technical field
The utility model is related to a kind of bearings.
Background technology
Bearing has generally comprised inner ring and outer ring, and sealing device is provided between the inner ring and outer ring, but existing
Sealing device sealing performance is poor, so as to be difficult suitable for the environment more demanding to sealing performance.
The content of the invention
In view of the deficiencies of the prior art, the utility model provides a kind of bearing with preferable sealing performance.
To achieve the above object, the utility model provides a kind of bearing with preferable sealing performance, includes inner ring
And outer ring, it is provided with sealing device between the inner ring and outer ring, the sealing device includes skeleton, sealing ring and close
Seal lid, the section of the skeleton is 7 fonts, and its transverse end is abutted against with outer ring inner ring face, the section of the sealing ring cover
For L-shaped, and its transverse end is mutually fixed with inner ring outer ring surface, and the sealing ring is fixed on skeleton, and it is corresponding be located at skeleton and
Between sealing ring cover, it is provided on the sealing ring radially applied against the first sealing lip in sealing ring cover transverse end, it is described
Sealing ring on be additionally provided with the second sealing lip that extension is tilted from radial inner end to radial outer end, on second sealing lip
It is provided with the sealing surface abutted against with sealing ring cover longitudinal end, and the corrugated setting of the sealing surface, the described second sealing
The spring ring that corrugated sealing surface is forced to be combined closely with sealing the formation of ring cover longitudinal end is additionally provided on lip.
The beneficial effects of the utility model are：Using the above structure, due to sealing device bag provided by the utility model
Skeleton, sealing ring and sealing ring cover have been included, the section of the skeleton is 7 fonts, and its transverse end is abutted against with outer ring inner ring face,
The section of the sealing ring cover is L-shaped, and its transverse end is mutually fixed with inner ring outer ring surface, and the sealing ring is fixed on skeleton
On, and it is corresponding between skeleton and sealing ring cover, therefore the skeleton and sealing ring cover form the rigid outer frame of sealing ring,
So as to form effective protection to sealing ring, and the sealing ring is not only formed by the first sealing lip with sealing the transverse end of ring cover
Sealing is also formed by the longitudinal end of the second sealing lip and sealing ring cover and sealed, therefore sealing performance is preferable, while the sealing
It is additionally provided with that corrugated sealing surface is forced to be indulged with sealing ring cover in the corrugated setting in face and second sealing lip
Form the spring ring combined closely to end, thus under the action of the spring ring not only can further lift-off seal effect, and
And can also be compensated automatically after sealing surface wear, thus in conclusion the utility model, which provides one kind, has preferable leakproofness
The bearing of energy.
The utility model, which can be further arranged to be additionally provided on the sealing ring, wraps skeleton transverse end end
Upper bound edge and the lower bound edge for wrapping skeleton longitudinal end end are additionally provided with radially outwardly projecting on the upper bound edge
Lug boss is correspondingly provided on the inner ring surface of the outer ring and forms the mating slot of interference with the lug boss.By above-mentioned
It sets, not only so that is combined between the sealing ring and skeleton is even closer secured, but also passes through the lug boss and slot
Cooperation, moreover it is possible to further stationary positioned sealing device.

The section of skeleton 3 is stated as 7 fonts, and its transverse end 31 is abutted against with 2 inner ring surface of outer ring, the section of the sealing ring cover 5 is L
Shape, and its transverse end 51 is mutually fixed with 1 outer ring surface of inner ring, the sealing ring 4 is fixed on skeleton 3, and corresponding positioned at skeleton 3
Between sealing ring cover 5, it is provided on the sealing ring 4 radially applied against the first sealing lip in sealing ring cover transverse end 51
41, it is additionally provided with the second sealing lip 42 that extension is tilted from radial inner end to radial outer end on the sealing ring 4, described the
The sealing surface 43 abutted against with sealing ring cover longitudinal end 52 is provided on two sealing lips 42, and the sealing surface 43 is corrugated sets
It puts, is additionally provided with that corrugated sealing surface 43 is forced to be formed tightly with sealing ring cover longitudinal end 52 on second sealing lip 42
The spring ring 6 of close combination.Be additionally provided on the sealing ring 4 the upper bound edge 44 that wraps 31 end of skeleton transverse end and
The lower bound edge 45 of 32 end of skeleton longitudinal end is wrapped, the lug boss of radially outwardly projecting is additionally provided on the upper bound edge 44
46, it is correspondingly provided on the inner ring surface of the outer ring 2 and forms the mating slot 21 of interference with the lug boss 46.By using
Said structure, the utility model provide a kind of bearing with preferable sealing performance.
