Abstract
The utility model relates to a kind of inner chamber and the double-row conical bearing of internal diameter all with sealing.The utility model comprises two inner rings and an outer ring, connect with jump ring between two inner rings, retainer is provided with between inner ring and outer ring, retainer is provided with double-row conical, Bearing inner grease up, bearing two ends are pressed with seal ring, it is characterized in that this bearing cavity sets up an O RunddichtringO, are provided with a backbone sealing ring in the end of an inner ring internal diameter of bearing.The utility model solves automobile hub bearing carrying, in using process grease from the leakage of the facet contacting point of two bearings inner ring, automotive hub can also be solved when running in the presence of a harsh environment, muddy water etc. enter internal diameter, cause the corrosion of internal diameter, reduce the problem of bearing life.
Description
Technical field
The utility model relates to a kind of automobile bearing, especially relates to a kind of inner chamber and the double-row conical bearing of internal diameter all with sealing.
Background technique
Automobile bearing has generally comprised inner ring, outer ring, is fixed with single-row or biserial roller between Internal and external cycle by retainer.Chinese patent discloses a kind of sealed double-row tapered roller bearing (Authorization Notice No.: CN 2625638Y) of new structure, it comprises an outer ring with double raceway, two single raceway inner rings, two retainers, a cone spacer between two row rollers and inner ring, the external diameter of outer ring is " V " font, in the exterior edge face of two retainers, each adaptation has a skeleton, each skeleton is all fitted and is combined with a seal ring, the sectional shape of skeleton, seal ring is like channel-section steel, and the material of seal ring is rubber.Chinese patent also discloses a kind of double-row conical bearing (Authorization Notice No.: CN 2864213Y) of two sides band dust-proof cover, it is made up of outer ring, inner ring, tapered roller, retainer and spacer ring, bearing outer ring both ends of the surface are with dust-proof cover, and outer ring is directly as the working surface supported.Above-mentioned automobile double-row conical bearing just solves the sealing of bearing self two end faces, thoroughly can not solve the leakage of lubricating grease from two inner ring surface of contact, and bearing is when rugged environment use, outside muddy water enters internal diameter, accelerate corrosion, reduce the life-span etc. of bearing.
Model utility content
The utility model is by a kind of inner chamber of design and the Novel double-row tapered roller bearing of internal diameter all with sealing, object to be to solve in automobile hub bearing carrying, using process grease from the leakage of the facet contacting point of two bearings inner ring, automotive hub can also be solved when running in the presence of a harsh environment, muddy water etc. enter internal diameter, cause the corrosion of internal diameter, reduce the problem of bearing life.
The utility model, to the problems referred to above, is mainly solved by following scheme:
A kind of inner chamber and the internal diameter Novel double-row tapered roller bearing all with sealing, comprise two inner rings and an outer ring, connect with jump ring between two inner rings, retainer is provided with between inner ring and outer ring, retainer is provided with double-row conical, Bearing inner grease up, and bearing two ends are pressed with seal ring, it is characterized in that this bearing cavity sets up an O RunddichtringO, be provided with a backbone sealing ring in the end of an inner ring internal diameter of bearing.
Described O RunddichtringO is fixed in the semi-circular groove of inner-ring small flange external diameter by retaining ring.
Described backbone sealing ring is by the axle interference fit with bearing fit.
The beneficial effects of the utility model are as follows:
1, bearing cavity sets up an O RunddichtringO, and is fixed on retaining ring in the semi-circular groove of inner-ring small flange external diameter, and when solving bearing carrying and use, grease is from the leakage of the facet contacting point of two bearings inner ring.
2, design a backbone sealing ring in the end of bearing one inner ring internal diameter, by with the axle of bearing fit and the interference fit of sealing circle, improve sealability, when solution automobile runs in the presence of a harsh environment, muddy water etc. enter internal diameter, accelerate corrosion, make the problem that bearing life reduces.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is inner chamber O RunddichtringO structure for amplifying schematic diagram.
Accompanying drawing 3 is internal diameter backbone sealing ring structure for amplifying schematic diagram.
In figure: seal ring 1, outer ring 2, inner ring 3, roller 4, retaining ring 5, O RunddichtringO 6, jump ring 7, retainer 8, seal ring 9, dust cover 10, backbone sealing ring 11.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of inner chamber as shown in Figure 1 and the internal diameter Novel double-row tapered roller bearing all with sealing, there are inner ring 3 and outer ring 2, connect with jump ring 7 between two inner rings, retainer 8 is provided with between inner ring and outer ring, retainer is provided with double-row conical 4, Bearing inner grease up, bearing the inner is provided with seal ring 9, and bearing two ends are pressed with seal ring 1 and seal ring 10.
As shown in Figure 2, with traditional double row tapered roller bearing unlike: this bearing cavity sets up an O RunddichtringO 6, and is fixed on retaining ring 5 in the semi-circular groove of inner-ring small flange external diameter.
As shown in Figure 3, a backbone sealing ring 11 is set up in internal diameter end.During use, backbone sealing ring 11 reaches the effect of inner diameter seal by the interference fit of the axle coordinated with it.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
