Abstract
The utility model discloses a heat -resisting bearing seal circle, include the rubber body of making plausible annular skeleton and attaching to the skeleton, the rubber body including connecting in the sealed lip of skeleton internal diameter edge and connecting in the location portion of skeleton external diameter edge, the axial extension on the terminal surface in the outside of skeleton has a plurality of heat dissipation thin slices. The utility model discloses can distribute the heat of bearing inner chamber when using, prevent that the sealing washer is hit by a bullet out from the bearing, improve the life of bearing.
Description
Technical field
The utility model relate to a kind of heat-resisting bearing sealed ring.
Background technology
Existing bearing sealed ring, using the rubber seal with skeleton, installed in the close of bearing axial direction two side ends face
In sealing groove, and make the structure that the inner lip of sealing ring contacts with interior ring recess.Because bearing can produce amount of heat after operating, because
The seal groove of bearing both sides end face is mounted on sealing ring, causes heat to distribute, and raises bearing cavity temperature, and pressure increases
Greatly, when bearing cavity after temperature, pressure exceed certain value, sealing ring will just be ejected seal groove by the gas of intraluminal inflation,
And then cause the impurity such as dust, water to enter into bearing cavity, while the lubricating grease in bearing can also overflow, it is scrapped in advance,
The service life of bearing is had a strong impact on.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of heat-resisting bearing sealed ring, can dissipate when in use
The heat of bearing cavity is sent out, sealing ring is prevented because HTHP is ejected from bearing, the service life of bearing is improve.
To achieve the above object, the utility model provide a kind of heat-resisting bearing sealed ring, including annular skeleton with
And the rubber bodies of skeleton are attached to, described rubber bodies include being connected to the sealed lip at skeleton inner diameter edge and being connected to
Location division at skeleton radial outer edge, it is axially extending on the end face on the outside of the direction of skeleton to have multiple radiating thin slices.
Advantage using above-mentioned technical proposal is：Due to bearing, in running, bearing cavity temperature can gradually rise, and pass through
The structure that radiating thin slice is set in skeleton end face outside can distribute the heat conducted to skeleton by bearing cavity, and then keep away
The problem for having exempted to cause bearing sealed ring to eject because of hypertonia in bearing cavity；And it is connected to the inside and outside footpath edge of skeleton
Rubber bodies the connection between sealing ring and bearing inner race and outer ring can be made even closer such that it is able to make bearing in high temperature resistant
In the case of can also keep sealing state.
Used as further improvement of the utility model, each radiating thin slice is annular, and multiple radiating thin slices are radially
Linear distribution.
Advantage using above-mentioned technical proposal is：Annular and radially the radiating thin slice of linear distribution are beneficial to processing and manufacture
And it is more attractive in appearance.
Used as further improvement of the utility model, described skeleton is opened up respectively at inner diameter edge and at radial outer edge
There is annular groove, the connecting portion in the insertion annular groove is correspondingly provided with rubber bodies.
Advantage using above-mentioned technical proposal is：Due to skeleton at inner diameter edge and at radial outer edge annular groove and
The setting of connecting portion in rubber bodies, can be easy to the cast and attachment of rubber bodies, the structure of sealing ring is more stablized.
As further improvement of the utility model, antirusting paint is scribbled on the radiating thin slice.
Advantage using above-mentioned technical proposal is：Because the radiating thin slice of skeleton is regular in extraneous air,
Easily corroded by water, air and solid particulate matter, can prevent skeleton from getting rusty using antirusting paint, further improving is made
Use the life-span.
Brief description of the drawings
Fig. 1 is the profile of the utility model embodiment；
Fig. 2 is the enlarged diagram of part A in Fig. 1.
Specific embodiment
The embodiment of heat-resisting bearing sealed ring of the present utility model is as shown in Figure 1-2：Skeleton 32 including annular and
It is attached to the rubber bodies of skeleton 32（31a, 31b）, described rubber bodies include being connected to the sealing lip at the inner diameter edge of skeleton 32
The portion 31b and location division 31a being connected at the radial outer edge of skeleton 32, it is axially extending on the end face on the outside of the direction of skeleton 32 to have
Multiple radiating thin slice 32b.In actual use, the location division 31a of the rubber bodies of sealing ring is connected in the outer ring 1 of bearing
In the sealing ring mounting groove 11 in footpath, and the sealed lip 31b of rubber bodies then constitutes certain work between the retaining wall of bearing inner race 2
Make gap.
1. it should be noted that the radiating thin slice 32b described in the utility model is shaped in skeleton 32, and skeleton 32
The preferential material stronger using thermal conductivity；Radiating thin slice 32b can be that each radiating thin slice is annular, and multiple radiating thin slices
Radially linear distribution, it is also possible to be arranged radially along the center of circle of skeleton 32 and the circumferentially distributed end face outside in skeleton 32
On, it is contemplated that the processing reason such as difficulty and cost, in the present embodiment, described radiating thin slice 32b preferably often
Individual radiating thin slice 32b is annular, and multiple thin slice 32b radially linear distributions that radiate.
In the present embodiment, described skeleton 32 offers annular groove 32a respectively at inner diameter edge and at radial outer edge,
Rubber bodies（31a, 31b）On be correspondingly provided with connecting portion in the insertion annular groove 32a.The setting of annular groove 32a can be easy to
Rubber bodies（31a, 31b）Cast and attachment, the mating reaction of annular groove 32a and connecting portion makes rubber bodies（31a, 31b）Do not allow
Easily come off separation from skeleton 32.
Further, since skeleton radiating thin slice 32b be exposed in the external environment beyond bearing cavity, be often subject to water,
The erosion of air and solid particulate matter, gets rusty easily in the course of time, has a strong impact on the service life of sealing ring, therefore can adopt
Hinder antirusting paint with being applied on skeleton radiating thin slice 32b, it would however also be possible to employ electroplating technology treatment skeleton radiating thin slice 32b makes it not
It is erodible.It is contemplated that plating is relatively costly, in the present embodiment, preferably scribble on the thin slice 32b of radiating it is anti-
Rust coating.
Above example, simply one kind of the utility model preferably specific embodiment, those skilled in the art are in this reality
It is included in protection domain of the present utility model with the usual variations and alternatives carried out in new technique aspects.
