Abstract
The utility model discloses a kind of sealing bearing, include inner ring, outer ring, ball and retainer, inner ring is sleeved on mandrel, ball is installed on retainer, and be correspondingly arranged between inner ring and outer ring, the axial length of outer ring is more than the axial length of inner ring, outer ring grows and is provided with sealing ring between the part of inner ring and mandrel, described sealing ring has internal ring portion and outer portion, internal ring portion is sleeved on mandrel, and it is provided with the lip contacting sealing with mandrel, outer portion is set in outside internal ring portion, and fit with the inner surface interference of outer ring, the axial outer end of internal ring portion and the axial outer end of outer portion are closed by radially connected portion and are connected, the ring spring making it radially-inwardly shrink also it is arranged with on described internal ring portion.By above-mentioned setting so that bearing provided by the utility model not only sealing effectiveness is more preferable, and can automatically repair compensation after sealing surface wear.
Description
Technical field
This utility model relates to a kind of bearing.
Background technology
Along with the extensive application of bearing, people it is also proposed higher requirement to the sealing effectiveness of bearing, but due to existing
The sealing structure of bearing is typically each provided between inner ring and outer ring, is therefore limited by installing space, the sealing effect of bearing
Fruit is the most not ideal enough, and existing sealing structure is after using abrasion, it is impossible to automatically repairs compensation, thus also accelerates sealing
The inefficacy speed of structure.
Summary of the invention
For the deficiencies in the prior art, this utility model provides a kind of sealing effectiveness energy more preferably and after sealing surface wear
Automatically the sealing bearing compensated is repaired.
For achieving the above object, this utility model provides a kind of sealing bearing, includes inner ring, outer ring, ball and guarantor
Holding frame, inner ring is sleeved on mandrel, and ball is installed on retainer, and is correspondingly arranged between inner ring and outer ring, the axle of outer ring
Be more than the axial length of inner ring to length, outer ring grows and is provided with sealing ring between the part of inner ring and mandrel, described sealing ring
Having internal ring portion and outer portion, internal ring portion is sleeved on mandrel, and is provided with the lip contacting sealing with mandrel, and outer portion is set in
Outside internal ring portion, and fitting with the inner surface interference of outer ring, the axial outer end of internal ring portion and the axial outer end of outer portion are by radially
Connecting portion is closed and is connected, and described internal ring portion is also arranged with the ring spring making it radially-inwardly shrink.
The beneficial effects of the utility model are: use said structure, due to sealing ring of the present utility model be installed in outside
Between circle and mandrel, therefore the installing space of sealing ring becomes much larger, and the sealing surface on sealing ring expands accordingly, and sealing effectiveness is more
Good, meanwhile, because being also arranged with the ring spring making it radially-inwardly shrink on described internal ring portion, therefore use abrasion in lip
After, by the inside contraction of ring spring, can automatically repair compensating sealing surface, thus be effectively improved sealing effectiveness, and greatly
The big service life extending sealing ring.
This utility model can be further arranged in the axial inner ends of internal ring portion be additionally provided with prevent ring spring axially sliding
Rib.Rib is set, can effectively prevent ring spring from use skidding off from sealing ring.
This utility model may further be provided as being embedded with inverted L-shaped skeleton in outer portion and radially connected portion.Inverted L is set
Shape skeleton, can be greatly reinforced the integral rigidity intensity of sealing ring, the sealing effectiveness of further lift-off seal circle.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Detailed description of the invention
Giving a kind of sealing bearing as shown in Figure 1, include inner ring 1, outer ring 2, ball 3 and retainer 4, inner ring 1 overlaps
Being contained on mandrel 5, ball 3 is installed on retainer 4, and is correspondingly arranged between inner ring 1 and outer ring 2, the axial length of outer ring 2
More than the axial length of inner ring 1, outer ring 2 grows and is provided with sealing ring 6 between the part of inner ring 1 and mandrel 5, described sealing ring 6
Having internal ring portion 61 and outer portion 62, internal ring portion 61 is sleeved on mandrel 5, and is provided with the lip 63 contacting sealing with mandrel 5, outward
Ring portion 62 is set in outside internal ring portion 61, and fits with the inner surface interference of outer ring 2, the axial outer end of internal ring portion 61 and outer portion 62
Axial outer end by radially connected portion 64 close connect, described internal ring portion 61 is also arranged with and makes it radially-inwardly shrink
Ring spring 7, the axial inner ends of internal ring portion 61 is additionally provided with the rib 65 preventing ring spring 7 axially sliding.Outer portion 62 He
It is embedded with inverted L-shaped skeleton 66 in radially connected portion 64.
Use said structure, owing to sealing ring 6 of the present utility model is to be installed between outer ring 2 and mandrel 5, therefore seal
The installing space of circle 6 becomes much larger, and the sealing surface on sealing ring 6 expands accordingly, and sealing effectiveness is more preferable, meanwhile, because of described interior
Also it is arranged with the ring spring 7 making it radially-inwardly shrink in ring portion 61, therefore after lip 63 uses abrasion, passes through annular elastomeric
The inside contraction of spring 7, can automatically repair compensating sealing surface, thus be effectively improved sealing effectiveness, and be greatly prolonged sealing ring 6
Service life.
