Abstract
The utility model discloses a bearing sealing ring with a circular ring shaped appearance, which comprises a rubber plate. A metal framework with a stepped section is arranged on the outer side of therubber plate, three upturned sealing lips are disposed on the inner side of the rubber plate, and the end portion of the metal framework is bent outward and in the shape of a semi-circle. The designof a semi-circle shape enables the sealing ring and a bearing to become hard to loose after the sealing ring and the bearing are joined, and the connection of the bearing and the sealing ring is enabled to be more stable. The bearing sealing ring has the advantages of simple structure and convenient processing and manufacturing. By arranging the metal framework on an inner portion, the overall hardness of the sealing ring can be enhanced. Moreover, the metal framework can not be easily corroded. By means of three sealing lips and specific angle setting, the fixation of the sealing ring and thebearing can be stabilized, and the sealing effect of the sealing ring can be fine, thereby effectively preventing dust and liquid from invading, stopping oil from releasing and reducing oil consumption. The sealing ring can not pop out, and simultaneously the bearing sealing ring can decrease the abrasion of the bearing and prolong the service life of the bearing.
Description
Technical field
The utility model relates to a kind of seal ring, especially a kind of bearing sealed ring.
Background technique
The existing bearing seal ring all adopts and will be installed in the seal groove of bearing outer ring both ends of the surface with the rubber seal of skeleton, and makes the inner lip and the interior ring recess contacting structure of seal ring.Because bearing can produce a large amount of heats after running, heat can't distribute, the bearing cavity temperature is raise, pressure increases, after the temperature and pressure of bearing cavity surpasses certain value, the gas that expands in the chamber just might eject seal ring, influences the working life of bearing, also might make the corollary equipment can't proper functioning.Simultaneously general bearing often needs to refuel in operation process, and the grease in the bearing can cling dust in air, makes it increase abrasive forces in operation process, weakens flexibility, thereby reduces the life-span.
Summary of the invention
The purpose of this utility model is that provide for the deficiency that solves above-mentioned technology a kind of has bearing sealed ring a plurality of sealing lips, hardness height, good sealing effect.
In order to achieve the above object, the bearing sealed ring that the utility model is designed, profile is a ring, it comprises offset plate, it is step-like metal frame that the offset plate outer ring is provided with the cross section, and the inboard of offset plate is provided with three retrousse sealing lips, the outwardly-bent semicircular in shape in the end of metal frame, semicircular design makes seal ring cooperate the difficult loosening of change afterwards with bearing, makes bearing more stable with being connected of seal ring.The stepped shaft top is a slope shape, and the offset plate inside bottom is provided with the slope.The angle of three retrousse sealing lips and vertical line all is 75., angle with rational be arranged so that sealing lip and bearing better fit and become more firm.The slope of offset plate inside bottom and the angle of vertical line be 45 ° parallel with stepped top.Offset plate can be mutually bonding with metal frame.Each place, right angle of stage shape metal skeleton is circular-arc, guaranteed like this metal frame and offset plate cooperate and fastening.
The resulting bearing sealed ring of the utility model, simple in structure, processing and fabricating is convenient.Establish metal frame by inside, can improve the integral hardness of seal ring, and metal frame is difficult for being corroded, by three sealing lips and specific angular setting, fixing of stabilized seal circle and bearing, can make the seal ring good sealing effect, effectively prevent the intrusion of dust, liquid, can stop leaking of grease again, reduce oil consumption, the phenomenon that seal ring ejects can not occur, reduce the wearing and tearing of bearing simultaneously, prolong the working life of bearing.
Description of drawings
Fig. 1 is the utility model embodiment 1 a structural representation.
Among the figure: offset plate 1, sealing lip 2, metal frame 3, slope 4, end 5.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1
As shown in Figure 1, the described bearing sealed ring of present embodiment, profile is a ring, it comprises offset plate 1, it is step-like metal frame 3 that offset plate 1 outer ring is provided with the cross section, and the inboard of offset plate 1 is provided with three retrousse sealing lips 2, the end 5 outwardly-bent semicirculars in shape of metal frame 3, semicircular design makes seal ring cooperate the difficult loosening of change afterwards with bearing, makes bearing more stable with being connected of seal ring.The stepped shaft top is a slope shape, and offset plate 1 inside bottom is provided with slope 4.Three retrousse sealing lips 2 all are 75 ° with the angle of vertical line, and it is more firm that angle with rational is arranged so that sealing lip 2 becomes with the bearing better fit.The slope 4 of offset plate 1 inside bottom and the angle of vertical line be 45 ° parallel with stepped top.Offset plate 1 is mutually bonding with metal frame 3, has guaranteed the stability that metal frame 3 and offset plate 1 are fixed.Stage shape metal skeleton 3 each place, right angle are circular-arc, guaranteed like this metal frame and offset plate cooperate and fastening.
