Description
Technical field
Field of bearings is the utility model is related to, more particularly to a kind of dust-proof sliding bearing of axial limiting.
Background technology
Bearing is a kind of important parts in contemporary plant equipment, and its major function is the mechanical rotary body of support, is dropped
Coefficient of friction in low mechanical rotary body motion process, and ensure its rotating accuracy.By the difference of motor element frictional property, axle
Rolling bearing and the major class of sliding bearing two can be divided into by holding, and wherein sliding bearing is normalized, seriation, but with rolling bearing phase
Smaller than its radial dimension, vibration and noise, price is relatively low.
The ability of sliding bearing bearing load is more much bigger than the rolling bearing of same volume, therefore, the radial direction of sliding bearing
Size is small.So bearing the occasion of big load and requiring the occasion that radial dimension is small, structural requirement is compact, more using sliding axle
Hold, sliding bearing is not generally high in axially position intensity and precision, it is impossible to its efficiency as rotational support body is given full play to, and
And in use, the dust-proof effect of sliding bearing is very poor, dust easily enters Bearing inner, reduces service life.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of axial limiting dust-proof sliding bearing, and lifting is axially
Limit strength and sealing.
In order to solve the above technical problems, the technical scheme that the utility model uses is：A kind of axial limiting is provided to prevent
The sliding bearing of dirt, including bearing outer ring and bearing inner race, the bearing inner race are arranged concentrically among bearing outer ring, the axle
Bearing outer-ring side indent is provided with the annular blind hole concentric with bearing inner race, and the bearing inner race outer wall evagination is provided with and bearing
The corresponding slip ring of the annular blind hole of outer ring, the annular blind hole opening indent are provided with the first square groove, and described first
Circlip is provided with square groove, Sealing shield ring is provided between the circlip and bearing inner race.
In one preferred embodiment of the utility model, the bearing inner race and slip ring are integrated.
In one preferred embodiment of the utility model, the annular blind hole inwall is provided with corresponding with Sealing shield ring
Second square groove.
In one preferred embodiment of the utility model, the concentricity of the bearing inner race and bearing outer ring is 0.02mm.
In one preferred embodiment of the utility model, the bearing outer ring inwall is provided with the outside of annular blind hole
Oil storage tank, the annular bright and beautiful body in sea is provided with the oil storage tank.
In one preferred embodiment of the utility model, the bearing outer ring side is provided with the L being connected with oil storage tank
Type oil filler point.
The beneficial effects of the utility model are：A kind of dust-proof sliding bearing of axial limiting that the utility model is pointed out, profit
The axial force being subject to the slip ring of inner ring is delivered in the annular blind hole side wall of bearing outer ring, and lifting axial limiting is strong
Spend, the Sealing shield ring in blind hole effectively prevents dust from entering Bearing inner, good airproof performance.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Other accompanying drawings are obtained, wherein：
Fig. 1 is a kind of structural representation of the dust-proof preferred embodiment of sliding bearing one of axial limiting of the utility model.
Embodiment
The technical scheme in the embodiment of the utility model will be clearly and completely described below, it is clear that described
Embodiment is only part of the embodiment of the present utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to
The scope of the utility model protection.
Referring to Fig. 1, the utility model embodiment includes：
A kind of dust-proof sliding bearing of axial limiting, including bearing outer ring 1 and bearing inner race 2, the bearing inner race 2 are concentric
It is arranged among bearing outer ring 1, the side indent of bearing outer ring 1 is provided with the annular blind hole 3 concentric with bearing inner race 2, institute
State the outer wall evagination of bearing inner race 2 and be provided with the slip ring 4 corresponding with the annular blind hole 3 of bearing outer ring 1, annular blind hole 3 and cunning
Rotating ring 4 is engaged the axial force and radial load that single direction can be born with sliding bearing, recessed in the annular opening of blind hole 3
The first square groove 5 is equipped with, circlip 6 is provided with first square groove 5, between the circlip 6 and bearing inner race 2
Sealing shield ring 7 is provided with, circlip 6 plays limit effect to bearing inner race 2 and Sealing shield ring 7.
The bearing inner race 2 and slip ring 4 are integrated, simple in construction, easy processing, and the axial force born is larger.
The inwall of annular blind hole 3 is provided with the second square groove 8 corresponding with Sealing shield ring 7, prevents that Sealing shield ring 7 is de-
Fall and strengthen the sealing effectiveness of sliding bearing.
The concentricity of the bearing inner race 2 and bearing outer ring 1 is 0.02mm, ensures that sliding bearing rotates smooth and work essence
Degree.
The inwall of bearing outer ring 1 is provided with the oil storage tank 9 positioned at the annular outside of blind hole 3, is provided with the oil storage tank 9
The annular bright and beautiful body 10 in sea, high lubricating effect.
The side of bearing outer ring 1 is provided with the L-type oil filler point 11 being connected with oil storage tank 9, easy to operate.
In summary, a kind of dust-proof sliding bearing of the utility model is pointed out axial limiting, improves sliding bearing and holds
By the axial force and sealing of single direction, suitable for the working environment that radial direction assembly space is small, bearing capacity is larger.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases
The technical field of pass, similarly it is included in scope of patent protection of the present utility model.
