Compared with prior art, it has the advantages that：

Sealing ring clamping described in the utility model is more secured, and deformation not easily to fall off can be very good to block dust, prevent Dust enters in bearing, greatly reduces bearing wear damage, improves service life.

Description of the drawings

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 below in conjunction with the accompanying drawings.

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 with Rolling element 3 is equipped between outer ring 2, the rolling element 3 is spherical shape, and the rolling element 3 is cased with retainer 31, and the retainer 31 draws Guide roll kinetoplast 3 is maintained in bearing, and the retainer 31 is isolated by rolling element 3 with rolling element 3, and the material of retainer 31 has one Determine intensity, and thermal conductivity is good, friction factor is small, wearability is good, impact flexibility is strong, density is smaller and linear expansion coefficient and rolling element 3 It is close.

Described 1 one end of inner ring extends outwardly, and the extended segment of the inner ring 1 is equipped with top wire hole 11, and the top wire hole 11 is installed There is a jackscrew 12, in inner ring 1 after installation axle, jackscrew 12 is withstood on axis, can play fixed function；2 outer wall of outer ring is equipped with and leads Oil groove 21,21 slot bottom of oil guide groove are equipped with oilhole 22, and the oilhole 22 penetrates through 2 inner wall of outer ring, can facilitate addition lubricating oil Or lubricating grease, bearing is maintained, reduces wear damage, extends bearing service life.

The outside of the rolling element 3 is equipped with sealing ring 4, and the sealing ring 4 includes skeleton 5, sealing lip 6 and rubber bodies 41, The skeleton 5 is to include top 51, middle part 52 and bottom 53, and the top 51 is hook, and 2 inner wall of outer ring is equipped with fitting groove 23,23 cell wall of fitting groove is equipped with limiting slot 24, and the top 51 is installed in limiting slot 24 so that sealing ring 4 assembles more Add securely not easily to fall off, while the middle part 52 tilts from inside to outside, and the bottom 53 extends downward close to inner ring 1, in dust After product overflow on skeleton, it can outward skid off, be not easily accessible in bearing along 52 outer wall of middle part, the rubber bodies 41 are fixed on skeleton 5 inner wall, the sealing lip 6 are arranged on 41 bottom surface of rubber bodies, and 41 inner wall of rubber bodies is equipped with strut 42, and the strut 42 pushes up Face is connected with top 51, and 42 bottom surface of strut is arranged in pairs or groups close to inner ring 1, the strut 42 with skeleton 5 so that sealing ring 4 is not easy Deformation, service life is longer, can preferably block dust, avoid enter into bearing.

6 bottom surface of sealing lip is in contact with 1 outer wall of inner ring, and the sealing lip 6 includes epipharynx 61, middle lip 62 and outer lip 63, it is equipped between the outer lip 63 and bottom 53 and forms the first hollow layer 64, second is formed between the middle lip 62 and outer lip 63 Hollow layer 65 forms third hollow layer 66 between the middle lip 62 and epipharynx 63, the sealing lip 6 of multilayer designs so that sealing ring 4 There are more outposts of the tax office, can firmly keep off on the outside dust, be not easily accessible in bearing, reduce bearing wear damage, significantly Improve service life.

Finally it should be noted that：Above example is 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 with reference to preferred embodiment, it will be understood by those of ordinary skill in the art 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 right of the utility model.
