The technical scheme providing for reaching above-mentioned purpose this utility model is：A kind of bearing with special seal circle, Including inner ring and outer ring, between described inner ring and outer ring, it is provided with rolling element, the both sides of described rolling element are provided with sealing ring, described close Seal includes sealing lip, skeleton and rubber bodies, and described rubber bodies are fixed on outer ring inwall, and described rubber bodies extend downwardly with Sealing lip is connected, and described sealing lip bottom is contacted with inner ring, and described sealing lip includes epipharynx and outer lip, described epipharynx and outer lip It is elliptical shape, and described outer lip and epipharynx ecto-entad tilt, and form sealing space, institute between described outer lip and epipharynx State skeleton and be arranged on rubber body sidewall.

Further, the inwall of described outer ring is provided with groove, and the top of described rubber bodies is fixing in a groove, described rubber The middle inside of body is provided with mounting groove, and described skeleton is fixed in mounting groove.

Further, the two ends of described inner ring stretch out in outer ring, are provided with top wire hole, in top wire hole in the section of stretching out of inner ring Equipped with jackscrew.

Further, described rolling element is circle, and described rolling element is cased with retainer, and described retainer guiding rolling element is protected Hold in bearing, rolling element is isolated by described retainer with rolling element.

Compared with prior art, have the advantages that：

Rubber bodies described in the utility model are extended downwardly and are connected with sealing lip, and described sealing lip bottom is contacted with inner ring, Described sealing lip includes epipharynx and outer lip, and described epipharynx and outer lip are elliptical shape, and described outer lip and epipharynx are by extroversion Tilted, form sealing space between described outer lip and epipharynx, described sealing lip can be good at blocking dust, it is to avoid dust enters Enter Bearing inner, outer lip and epipharynx are ellipse and have certain elasticity simultaneously, when dust sealing lip overflow amass certain Degree, dust can effectively be flicked by described sealing lip, preferably keeps the cleaning in bearing so that bearing can be using more Lengthen long.

Brief description

Fig. 1 is this utility model structural representation.

Fig. 2 is this 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 seal circle, including inner ring 1 and outer ring 2, described inner ring 1 He It is provided with rolling element 3, described rolling element 3 is circle, described rolling element 3 is cased with retainer 31, and described retainer 31 draws between outer ring 2 Guide roll kinetoplast 3 is maintained in bearing, and rolling element 3 is isolated by described retainer 31 with rolling element 3, and the material of retainer 31 has one Determine intensity, and heat conductivity is good, friction factor is little, wearability good, impact flexibility is strong, density is less and linear expansion coefficient and rolling element 3 It is close；The two ends of described inner ring 1 stretch out in outer ring 2, are provided with top wire hole 11 in the section of stretching out of inner ring 1, fill in top wire hole 11 There is jackscrew 12, after installation axle in inner ring 1, jackscrew 12 withstands on axle, can play fixation.

The both sides of described rolling element 3 are provided with sealing ring 4, and described sealing ring 4 includes sealing lip 41, skeleton 42 and rubber bodies 43, described rubber bodies 43 are fixed on outer ring 2 inwall, and the inwall of described outer ring 2 is provided with groove 21, and the top of described rubber bodies 43 is solid It is scheduled in groove 21, described skeleton 42 is arranged on rubber bodies 43 side wall, the middle inside of described rubber bodies 43 is provided with mounting groove 44, Described skeleton 42 is fixed in mounting groove 44, and described skeleton 42 can effectively support rubber bodies 43 so that rubber bodies 43 are difficult Bending, can effectively block dust.

And described rubber bodies 43 are extended downwardly and are connected with sealing lip 41, described sealing lip 4 bottom is contacted with inner ring 1, Described sealing lip 4 includes epipharynx 45 and outer lip 46, and described epipharynx 45 and outer lip 46 are elliptical shape, and described outer lip 46 He Epipharynx 45 ecto-entad tilts, and forms sealing space 47 between described outer lip 46 and epipharynx 45, and described sealing lip 4 can be good at Block dust, it is to avoid dust enters Bearing inner, and described outer lip 46 and epipharynx 45 are ellipse and have certain bullet simultaneously Property, amass to a certain extent when dust overflows in sealing lip 4, dust can effectively be flicked by described sealing lip 4, more preferable holding shaft Cleaning in holding so that bearing can use more permanent.

Finally it should be noted that：Above example only in order to the technical solution of the utility model to be described and unrestricted, although With reference to preferred embodiment, this utility model is described in detail, it will be understood by those within the art that, can be right The technical solution of the utility model is modified or equivalent, the spirit without deviating from technical solutions of the utility model and model Enclose, it all should be covered in the middle of right of the present utility model.
