Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged view of the I of Fig. 1.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the outer astragal O type circle axial damping bearing providing in figure, comprises bearing inner race 100, bearing outer ring 200, retainer 300, seal ring 400 and sealing cover 500.
Retainer 300, seal ring 400 and sealing cover 500 are all arranged between bearing inner race 100 and bearing outer ring 200, wherein seal ring 400 is arranged on the side near driving source, sealing cover 500 is arranged on the side away from driving source, on the ball pocket of retainer 300, be placed with ball 310, bearing outer ring 200 is provided with an O type circle 600 with the end face of seal ring 400 homonymies, this O type circle 600 is one-body molded with seal ring 400, effectively solve the problem that produces gap between prior art middle (center) bearing and damping washer, make damping effect better, and make assembling simpler.On the annular end face of O type circle 600, be provided with 12 even protruding grains 610 spaced apart; this protruding grain 610 is rectangular-shaped protruding grain; protruding grain 610 has avoided the body of O type circle 600 directly to contact with the end face of driving source; thereby what occur that first whens wearing and tearing wear and tear is the protruding grain 600 of directly contact; so effectively protect the body of O type circle 600, thereby extended the working life of O type circle 600.In order to make to coordinate better between bearing and bearing support, prevent the relative displacement between bearing and bearing support, on the outer ring surface of bearing outer ring 200, be nested with two rubber rings 700.
Referring to Fig. 2, seal ring 400 comprises skeleton 410 and is coated on skeleton 410 seal 420 around, seal 420 comprises sealed outer ring portion 421 and sealing inner ring portion 422, the head of sealed outer ring portion 421 coordinates with the dustproof groove 210 of bearing outer ring 200, the back of sealed outer ring portion 421 extends outward connecting bridge 421a, and this connecting bridge 421a is in order to link together seal ring 400 and O type circle 600.The head of seal ring inner ring portion 422 is provided with non-contact sealing lip limit 422a, non-contact sealing lip limit 422b and contact sealing lip limit 422c, between the dustproof groove 110 outer ledge tops of non-contact sealing lip limit 422a and bearing inner race 100, leave slight clearance, between dustproof groove 110 tops, inside edge of non-contact sealing lip limit 422b and bearing inner race 100, leave slight clearance, surround dustproof chamber 430 by the dustproof groove 110 of head, non-contact sealing lip limit 422b and bearing inner race 100 of non-contact sealing lip limit 422a, sealing inner ring portion 422.Sealing lip limit 422c is between non-contact sealing lip limit 422a and non-contact sealing lip limit 422b in contact, the top of this contact sealing lip limit 422c withstands on the bottom land of dustproof groove 110 of bearing inner race 100, and the chamber 430 of preventing dust is separated into front dustproof chamber 431 and rear dustproof chamber 432.
Non-contact sealing lip limit 422a can prevent that the impurity such as most of extraneous dust from entering between bearing outer ring 100 and bearing inner race 200, along with the erosion of the impurity such as dust to bearing, part dust impurity can enter in front dustproof chamber 431, the pressure of 431 outsides, front dustproof chamber reduces because spatial expansion causes its pressure, the further erosion kinetic of the impurity such as dust reduces, the impurity such as nearly all dust can rest in front dustproof chamber 431, add that contact sealing lip limit 422c further stops dust impurity to enter between bearing outer ring 100 and bearing 200, sealing effect is better.If contact sealing lip limit 422c is etched or weares and teares, even if the impurity such as dust pass contact sealing lip limit 422c, but the chamber 432 of preventing dust afterwards also can weaken the erosion kinetic of the impurity such as dust, has further improved the sealing effect of bearing.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
