Description
Technical field
It the utility model is related to bearing, more particularly to shield bearing.
Background technology
Bearing be with a kind of very important parts in contemporary plant equipment, its major function be formed into rotary shaft or
Other movable bodies, guiding rotation or moving movement simultaneously bear the load being transmitted to by axle or Wednesday part.Existing bearing exists
During use, ball is easy to be corroded by dust, greasy dirt etc., so as to which ball can be caused stuck or worn, then shortens
The service life of ceramic bearing.Market also has some bearings to be provided with dust cap, but the edge of dust cap and bearing inner race
Periphery between have larger gap, and the outer surface of dust cap is very smooth, and dust falls after dust-proof cap surface easily again
Secondary movement is floatd into the gap between dust cap and bearing inner race, hence into Bearing inner, is corroded ball, is reduced making for bearing
With the life-span, and traditional dust cap easily comes off during bearing operation, can also reduce the service life of bearing.
The content of the invention
The utility model is undesirable for dustproof design effect of the prior art and the shortcomings that easily come off, there is provided anti-
Dirt bearing.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：
Shield bearing, including bearing inner ring, outer race and the roller between bearing inner ring and outer race, axle
Hold and dustproof gasket is installed between inner ring and outer race, outer race is provided with the dust guiding groove through outer race both sides, prevents
The side of dirt pad towards roller is defined as inner side, and the opposite side of dustproof gasket is defined as outside, the one end open of dust guiding groove with
The outer surface distance 2-4mm of dustproof gasket, is fixed with dust removal brush on bearing inner ring, the bristle of dust removal brush with the outside of dustproof gasket
Surface contact, dust removal brush by bearing inner ring drive and the dust on dustproof gasket is swept into dust guiding groove, on bearing inner ring also
Provided with through hole, through hole is located at the opening position between the outer surface and dust removal brush of dustproof gasket.Pass through dust guiding groove and dust removal brush
Coordinate and the dust accumulated on dustproof gasket is guided and removed, dust is discharged by dust guiding groove outside bearing, ensure that axle
The normal work held, increase the physical life of bearing, it is simple and reasonable for structure, it is practical.
Preferably, the opening of dust guiding groove towards bearing inner ring sets dust retaining ring.Dust retaining ring is set to have on dust guiding groove
Effect prevents that the dust into dust guiding groove from being blown back in bearing again, ensure that the efficient of dedusting.
Preferably, dustproof gasket tilts towards outer race.Dust natural subsidence is made extremely by the inclined setting of pad
The opening of dust guiding groove, is easy to dedusting.
Preferably, through hole is the hole that diameter tapers into, the small-caliber end of through hole is located on the outside of bearing inner ring, through hole
Heavy caliber end is located on the outside of bearing inner ring.By the design of through hole, air can be guided to form air-flow and coordinate dust removal brush by dust
Bring dust guiding groove into.
The utility model has significant technique effect as a result of above technical scheme：Pass through dust guiding groove and dedusting
The cooperation of brush is guided and removed to the dust accumulated on dustproof gasket, dust is discharged by dust guiding groove outside bearing, is ensured
The normal work of bearing, increases the physical life of bearing, simple and reasonable for structure, practical.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
The toponym that each number designation is referred in accompanying drawing is as follows：1-bearing inner ring, 2-outer race, 3-roller,
4-dustproof gasket, 11-dust removal brush, 12-through hole, 21-dust guiding groove, 211-dust retaining ring.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Embodiment 1
Shield bearing, as illustrated, including bearing inner ring 1, outer race 2 and installed in bearing inner ring 1 and outer race 2
Between roller 3, dustproof gasket 4 is installed, outer race 2 is provided with outside bearing between bearing inner ring 1 and outer race 2
The dust guiding groove 21 of the both sides of ring 2, the side of dustproof gasket 4 towards roller 4 are defined as inner side, and the opposite side of dustproof gasket 4 is defined as
Outside, the one end open of dust guiding groove 21 and the outer surface distance 2-4mm of dustproof gasket 4, dust removal brush is fixed with bearing inner ring 1
11, the bristle of dust removal brush 11 is contacted with the surface in the outside of dustproof gasket 4, and dust removal brush 1 is driven by bearing inner ring 1 and by dustproof gasket
Dust on 4 is swept into dust guiding groove 21, and through hole 12 is additionally provided with bearing inner ring 1, and through hole 12 is located at the outer surface of dustproof gasket 4
With the opening position between dust removal brush 11.
The opening of dust guiding groove 21 towards bearing inner ring 1 sets dust retaining ring 211.
Dustproof gasket 4 tilts towards outer race 2.
Through hole 12 is the hole that tapers into of diameter, and the small-caliber end of through hole 12 be located on the outside of bearing inner ring 1, through hole 12 it is big
Bore end is located at the outside of bearing inner ring 1.
Due to the design of dust guiding groove 21, when bearing inner ring 1 rotates relative to outer race 1, it is fixed on bearing inner ring 1
Dust removal brush 11 dust on dustproof gasket 4 is purged and dust is pushed into close to outer race 2, rotated in addition in bearing
When, the air-flow of cooperation through hole 12, dust is gradually promoted and discharged in dust guiding groove 21 and by dust guiding groove 21 outside bearing.
In a word, preferred embodiment of the present utility model is the foregoing is only, it is all according to present utility model application the scope of the claims institute
The equivalent changes and modifications of work, it should all belong to the covering scope of the utility model patent.
