Abstract
This utility model relates to a kind of taper roll bearing, the double-row conical bearing of a kind of good airproof performance, belongs to bearing mnanufacture technical field.Including skeleton, duplex bearing inner ring, bearing outer ring, taper roller and retainer, at skeleton, laminating is provided with rubber seal, and rubber seal uses many structure of sealing lips, and the sealing lip of rubber seal extends to Bearing outer；Sealing ring protective cover it is provided with on the outer face of duplex bearing inner ring.The sealing lip of rubber seal is extended to Bearing outer by this utility model, increases its sealing effectiveness, efficiently solves the short problem causing sealing effectiveness the best of sealing lip；Also set up sealing ring protective cover in the outside of rubber seal, protection extends to the sealing lip of outside, prevents sealing lip from damaging in transportation.
Description
Technical field
This utility model relates to a kind of taper roll bearing, the double-row conical bearing of a kind of good airproof performance, belongs to bearing mnanufacture technical field.
Background technology
Taper roll bearing belongs to divergence type bearing, the inside and outside circle of bearing is respectively provided with tapered raceway, this class bearing is divided into the different structures such as single-row, biserial and four-row tapered roller bearing by the columns of filled roller, radial load and single direction axial load can be born for single-row tapered roller bearing, when bearing bears radial load, an axial thrust load will be produced, so needing another bearing that can bear opposite direction axial force to be balanced.
Taper roll bearing many employings open architecture, without any sealing structure or dustproof construction, this open type design bearing because of extraneous and bearing working cannot be separated from, cause the life-span of bearing or running accuracy to be affected by certain.At present, also there are some double-row conical bearings to use and seal structure, but sealing lip is short or the sealing ring problem causing sealing effectiveness the best easy to wear because designed sealing ring exists.
Utility model content
For these reasons, the purpose of this utility model is to provide the double-row conical bearing of a kind of good airproof performance.
To achieve these goals, the technical scheme that this utility model is used is:
A kind of double-row conical bearing of good airproof performance, including skeleton, duplex bearing inner ring, bearing outer ring, taper roller and retainer, at skeleton, laminating is provided with rubber seal, and rubber seal uses many structure of sealing lips, and one of them sealing lip extends to Bearing outer；Sealing ring protective cover it is provided with on the outer face of duplex bearing inner ring.
The cross section of described sealing ring protective cover is fold-line-shaped structure; this fold-line-shaped structure is combined by a right-angle structure and an obtuse angle structure connection; wherein right-angle structure is fitted with inner face and the outer face of duplex bearing inner ring, and obtuse angle structure is away from the outer face of duplex bearing inner ring.
On described duplex bearing inner ring, symmetry offers annular groove, and the two ends of U-shaped adapter sleeve are connected in two grooves of symmetry respectively.
The cross section of described skeleton is L-type, and the two of which sealing lip of rubber seal is U-shaped, and U-shaped sealing lip fits in medial surface and the lateral surface of skeleton.
The sealing lip of rubber seal is extended to Bearing outer by this utility model, increases its sealing effectiveness, efficiently solves the short problem causing sealing effectiveness the best of sealing lip；Also set up sealing ring protective cover in the outside of rubber seal, protection extends to the sealing lip of outside, prevents sealing lip from damaging in transportation.
Below by way of the drawings and specific embodiments, this utility model is further elaborated.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structure for amplifying schematic diagram that in Fig. 1, rubber seal is fitted with skeleton.
Detailed description of the invention:
Shown in Fig. 1 and Fig. 2, the double-row conical bearing of a kind of good airproof performance that this utility model provides, including skeleton 4, duplex bearing inner ring 2, bearing outer ring 1, taper roller 3 and retainer 6, at skeleton 4, laminating is provided with rubber seal 7, the cross section of skeleton 4 is L-type, rubber seal 7 uses many structure of sealing lips, wherein sealing lip 71 and sealing lip 72 constitute U-shape structure, tightly fitted and envelope in the interior outer face of skeleton 4 by the sealing lip of U-shape structure, and externally-located sealing lip 72 length is more than sealing lip 71 so that sealing effectiveness is more preferable；One of them sealing lip 73 of rubber seal 7 extends to the outside of bearing, further enhancing the sealing effectiveness to bearing.Damage in transportation in order to avoid extending to the sealing lip 73 of outside; and then affect its sealing effectiveness; on the outer face of duplex bearing inner ring 2, also it is provided with sealing ring protective cover 8; the cross section of sealing ring protective cover 8 is fold-line-shaped structure; this fold-line-shaped structure is combined by a right-angle structure and an obtuse angle structure connection; wherein right-angle structure is fitted with inner face and the outer face of duplex bearing inner ring 2, and obtuse angle structure is away from the outer face of duplex bearing inner ring 2.
Further setting as such scheme, on duplex bearing inner ring 2, symmetry offers annular groove (not marking in figure), the two ends of U-shaped adapter sleeve 5 are connected in two grooves of symmetry respectively, the inner ring of two taper roll bearings is tightly connected together by U-shaped adapter sleeve 5, prevents bearing inner ring assembly in transportation from separating with outer ring.
Above example is only in order to illustrate the technical solution of the utility model and unrestricted, other amendment or equivalents that the technical solution of the utility model is made by those of ordinary skill in the art, without departing from the spirit and scope of technical solutions of the utility model, all should contain in right of the present utility model.
