Performance, but also have certain limitation.During synchronous press mounting, if controlling bad, it is easy to cause the sealing ring axial lip magnitude of interference
Too small or excessive, too small meeting sealing effectiveness is bad, crosses conference and causes moment excessive.
Other special circumstances, the spacing of circle rib as inside and outside in bearing is less, and conventional seal structure design space is not
Foot.
Summary of the invention
The present utility model purpose: for the defect overcoming prior art to exist, this utility model provides one to facilitate group
Conjunction sealing ring press-fits, and press-fits precision high, the combination sealing ring sealing mechanism of the bearing of good sealing effect.
For achieving the above object, this utility model provides following technical scheme: the combination sealing ring of a kind of bearing is close
Sealing mechanism, including bearing inner race, bearing outer ring and combined seal ring, described combined seal ring is positioned at outside bearing inner race and bearing
Between circle, described combined seal ring includes ring framework and the outer ring framework of L-type in L-type, ring framework and the outer ring framework phase of L-type in L-type
There is the rectangular configuration of sealing cavity to being arranged to inside, in annular seal space body, be provided with rubber seal lip, it is characterised in that: described axle
Hold on the outer circumference surface of inner ring and on the inner peripheral surface of bearing outer ring, be equipped with step annular groove, bearing outer ring top bar annular groove with
Step annular groove corresponding matching on bearing inner race forms axial limiting setting-in mouth, and it is embedding that described combined seal ring is flush-mounted in axial limiting
In dress mouth, the external diameter ring body of combined seal ring is conflicted spacing cooperation with the axial face of the step annular groove on bearing outer ring, combines close
The internal diameter ring body of seal is conflicted spacing cooperation with the axial face of the step annular groove on bearing inner race.
By using technique scheme, the inside and outside circle of bearing increases a step annular groove design, by the position of step
Put limit combined seal ring press-fit the degree of depth, it is ensured that press-fit precision, consequently facilitating the axial rubber lip ensured in annular seal space body
The magnitude of interference, step design can increase the distance between seal combination outer diameter face and aperture surface simultaneously, bearing inside and outside circle gear
When the spacing on limit is less, apply this structure, it is ensured that space is more sufficient so that sealing effectiveness is more preferable.
Preferably, the corner of described inner ring step annular groove is provided with R groove.
Preferably, the corner of described outer ring step annular groove is provided with R groove.
Under the design of above-mentioned preferred structure, the design of R groove, not only convenient processing, and improve combined seal ring press-fit essence
Degree.
Preferably, the axial face for the step annular groove of described L-type inner ring framework location extends radially beyond described L-type inner ring
The radial direction ring body of skeleton.
Under the design of above-mentioned preferred structure, owing to coordinating with the conflict of the axial face of step annular groove at the knuckle of ring framework in L-type,
Therefore on the step annular groove that will coordinate with ring framework in L-type, axial face extended height crosses L-type, the radial direction ring body of ring framework, makes
Must press-fit the most reliable.
Below in conjunction with the accompanying drawings this utility model is further described.
Accompanying drawing explanation
Fig. 1 is existing combined sealing structure schematic diagram；
Fig. 2 is the combination sealing ring sealing mechanism structural representation of this utility model specific embodiment bearing.
Detailed description of the invention
Seeing accompanying drawing 2, the combination sealing ring sealing mechanism of a kind of bearing disclosed in this utility model, including bearing inner race
1, bearing outer ring 2 and combined seal ring 3, described combined seal ring 3 between bearing inner race 1 and bearing outer ring 2, described group
Close sealing ring 3 and include ring framework 31 and the outer ring framework 32 of L-type in L-type, ring framework 31 ring framework 32 relative cloth outer with L-type in L-type
It is set to inside and has the rectangular configuration sealing cavity 33, in sealing cavity 33, be provided with rubber seal lip 34, described bearing inner race 1
Being equipped with step annular groove 11,21 on outer circumference surface and on the inner peripheral surface of bearing outer ring 2, bearing outer ring 2 is topped bar annular groove 21
Forming axial limiting setting-in mouth with step annular groove 11 corresponding matching on bearing inner race 1, described combined seal ring 3 is flush-mounted in axially
In spacing setting-in mouth, the axial face 211 of the external diameter ring body 311 of combined seal ring 3 and the step annular groove 21 on bearing outer ring 2 is conflicted
Spacing cooperation, the axial face 111 of the internal diameter ring body 321 of combined seal ring 3 and the step annular groove 11 on bearing inner race 1 is conflicted spacing
Coordinate.In this specific embodiment, in the L-type of combined seal ring 3, ring framework 31 is topped bar with bearing outer ring 2, and annular groove 21 is corresponding joins
Closing, the outer ring framework of the L-type of combined seal ring 3 32 and bearing inner race 1 are topped bar annular groove 11 corresponding matching, therefore combined seal ring 3
External diameter ring body 311 correspond to the radial direction ring body 311 of ring framework 31 in L-type, the internal diameter ring body 321 of combined seal ring 3 corresponds to L
The radial direction ring body 321 of the outer ring framework 32 of type；Certainly as this utility model another kind form, the L-type inner ring bone of combined seal ring 3
Frame and bearing inner race are topped bar annular groove corresponding matching, and the outer ring framework of the L-type of combined seal ring 3 and bearing outer ring are topped bar annular groove pair
Should coordinate, then the external diameter ring body of combined seal ring 3 corresponds to the radial direction ring body of the outer ring framework of L-type, the internal diameter ring of combined seal ring 3
Body corresponds to the radial direction ring body of ring framework in L-type.For ease of describing further improvement of the utility model structure, below with this tool
The form of body embodiment carries out label and is described.
For ease of the processing of ring-shaped step groove, the corner of described inner ring step annular groove 11 is provided with R groove 112.Described outer ring platform
The corner of rank annular groove 21 is provided with R groove 212.The design of R groove, not only convenient processing, and improve combined seal ring press-fit precision.
Coordinate owing to conflicting with the axial face of step annular groove at the knuckle of ring framework in L-type, will be for ring framework in described L-type
The axial face 211 of step annular grooves 21 of 31 location extends radially beyond the radial direction ring body 311 of ring framework 31 in described L-type.Thus
Make to press-fit the most reliable.
This utility model causes inside without location in combined seal ring two seal combinations during assembling
The problem that the rubber seal lip magnitude of interference cannot be effectively controlled, improves the assembling structure of existing combined seal ring,
Increase a step annular groove design on the inside and outside circle of bearing, limited the degree of depth that press-fits of combined seal ring by the position of step, protect
Card press-fits precision, and step design can increase the distance between seal combination outer diameter face and aperture surface simultaneously, at the inside and outside circle of bearing
When the spacing of rib is less, apply this structure, it is ensured that space is more sufficient so that sealing effectiveness is more preferable.
