Description
Technical field
The utility model relates to bearing, in particular to a kind of bearing with special sealing circle.
Background technique
Bearing is a kind of important spare part in contemporary mechanical equipment.Its major function is to support mechanical rotary body, is reduced
Coefficient of friction in its motion process, and guarantee its rotating accuracy.Bearing is in use, sealing and anti-dust performance due to bearing
It is bad, it is easy excessive dust stratification dirt, and enter in bearing cavity, causes bearing wear to damage, substantially reduce the service life of bearing.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of bearing with special sealing circle, it is not easy to overflow
Dust stratification dirt has good anti-dust performance, can greatly reduce the wear damage of bearing, prolong the service life.
To reach above-mentioned purpose technical solution provided by the utility model is: a kind of bearing with special sealing circle, packet
Inner ring and outer ring is included, rolling element is equipped between the inner ring and outer ring, the rolling element two sides are equipped with sealing ring, the sealing ring
For n shape, the sealing ring includes rubber bodies and skeleton, and rubber bodies bottom surface ecto-entad is respectively equipped with the first sealing lip and
Two sealing lips, the sealing ring are in n shape, and first sealing lip and the second sealing lip are equipped with air bag layer, and described first, second
Sealing lip inner sidewall is equipped with limiting slot, and the skeleton is mounted in limiting slot, and the outer ring inner wall is equipped with fitting groove, the rubber
For colloid top card in fitting groove, link slot, first sealing lip and the second sealing lip bottom is distributed in the interior ring outer wall
Portion is installed in link slot respectively.
Further, the outer ring is equipped with oilhole, and the oilhole penetrates through outer ring inside and outside wall, and the oilhole outer end opening is equipped with
Oil guide groove.
Further, the rolling element is spherical shape, and the rolling element is cased with retainer, and the retainer is by rolling element and rolls
Kinetoplast isolation.
Compared with prior art, it has the advantages that
The utility model can flick the dust for being attached to sealing ring under the action of air bag layer elastic force, while skeleton can
To support the first sealing lip well, not flexible abrasion extends sealing ring service life, and second sealing lip can be into one
Step reinforces the leakproofness of bearing, and after the first sealing lip wear damage, the second sealing lip equally can be good at blocks dust, keep away
Exempt to enter bearing inner race, greatly prolongs bearing service life.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the utility model ring structure schematic diagram.
The utility model is described in further detail with reference to the accompanying drawing.
Specific embodiment
As depicted in figs. 1 and 2, a kind of bearing with special sealing circle, including inner ring 1 and outer ring 2, the inner ring 1 and outer
Rolling element 3 is equipped between circle 2, the rolling element 3 is spherical shape, and the rolling element 3 is cased with retainer 31, and the retainer 31 will rolling
Kinetoplast 3 is isolated with rolling element 3, and the material of retainer 31 has some strength, and thermal conductivity is good, friction factor is small, wearability is good,
Impact flexibility is strong, density is smaller and linear expansion coefficient is close with rolling element 3, and the outer ring 2 is equipped with oilhole 21, and the oilhole 21 passes through
Logical 2 inside and outside wall of outer ring, 21 outer end opening of oilhole are equipped with oil guide groove 22, it may be convenient to add lubricant or lubrication for bearing
Oil reduces bearing friction power, prolongs the service life.
3 two sides of rolling element are equipped with sealing ring 4, and the sealing ring 4 is n shape, and the sealing ring 4 includes 41 He of rubber bodies
Skeleton 42, the 41 bottom surface ecto-entad of rubber bodies are respectively equipped with the first sealing lip 43 and the second sealing lip 44, the sealing ring 4
In n shape, first sealing lip 43 and the second sealing lip 44 are equipped with air bag layer 45, in first, second sealing lip 43,44
Side wall is equipped with limiting slot 46, and the skeleton 42 is mounted in limiting slot 46, and 2 inner wall of outer ring is equipped with fitting groove 23, described
For 41 top card of rubber bodies in the fitting groove 23,1 outer wall of inner ring is distributed with link slot 11, first sealing lip 43 and the
Two sealing lips, 44 bottom is installed on respectively in link slot 11, and bearing in use for some time, is easy excessive dust stratification dirt and is attached to
On first sealing lip, 43 outer wall, gravity of first sealing lip 43 by dust will be grey under the elastic force effect of air bag layer 45
Dirt flicks, while skeleton 42 can be very good the first sealing lip 43 of support, and not flexible abrasion extends 4 service life of sealing ring,
Second sealing lip 44 can further strengthen the leakproofness of bearing, after 43 wear damage of the first sealing lip, the second sealing
Lip 44 equally can be good at blocks dust, avoid enter into bearing, greatly prolong bearing service life.
Finally, it should be noted that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although
The utility model is described in detail referring to preferred embodiment, those skilled in the art should understand that, it can be right
The technical solution of the utility model is modified or replaced equivalently, without departing from the spirit and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
