Description
Technical field
The present invention relates to a kind of bearings, more specifically, it relates to which a kind of full ball fills full-ceramic bearing.
Background technology
Existing bearing generally comprises the bearing inner race of bearing outer ring, rolling element and one, in process of manufacture,
Because bearing roller will be installed on the trench interiors between bearing internal external circle, the bearing inner race of integrated design limits bearing element
Body is directly loadable into, and existing method is that bearing inner race bias is made to be packed into the method for rolling element, heating outer ring plavini, squeeze outer ring
Deformation method is pressed directly into the methods such as outer ring.
The above method limits rolling element installation number, some are squeezed, press-loading process damages parts of bearings, influence the bearing longevity
Life, complicated technique also limits the load-carrying ability of bearing, and the replacement rate of bearing is low, and voluntarily assembling is difficult, after the completion of installation
The concentricity tolerance of bearing outer ring and bearing inner race is big, and overall effect is bad.Accordingly, the present invention proposes a kind of full full pottery of ball dress
Porcelain bearing.
Invention content
It is an object of the invention to overcome above-mentioned deficiency in the prior art, a kind of full ball dress full-ceramic bearing is provided, it should
Bearing has the characteristics that rolling element install convenient, and the concentricity tolerance of bearing outer ring and bearing inner race is small after the completion of installation, turns
Dynamic effect is good.
In order to solve the above technical problems, the object of the present invention is achieved like this：A kind of full ball dress according to the present invention
Full-ceramic bearing, including bearing outer ring, bearing inner race and the rolling element between bearing outer ring and bearing inner race, the axis
It holds inner ring to be made of inner ring under inner ring on bearing and bearing, bearing block is embedded in the bearing inner race, bearing block has protrusion
Ear in the bearing inner race upper surface, ear are fixed in the bearing inner race upper surface by pressing, and the bearing block is also
With the ring flat-plate for being connected to bearing inner race lower face, the ring equal with ring flat-plate outer diameter is offered on the lower face of the bearing outer ring
Shape slot, ring flat-plate are embedded in the annular groove, and the ring flat-plate upper surface fitting annular groove groove wall.
The present invention is further arranged to：The annular groove has the semicircle annular groove being opened on bearing outer ring, semicircle
The semi-cylindrical hill ring being integrated with the ring flat-plate is embedded in annular groove.
The present invention is further arranged to：The bearing outer ring, bearing inner race, rolling element and bearing block are ceramic material.
In conclusion the invention has the advantages that：Full ball according to the present invention fills full-ceramic bearing, pass through by
Bearing inner race is fabricated to be spliced by upper and lower two parts, changes the installation technique of rolling element, is added convenient for rolling element, reduction pair
The abrasion of bearing；Bearing inner race lower face is abutted by bearing block lower end ring flat-plate, upper end ear is riveted on bearing inner race upper surface,
Play the role of fastening on bearing inner ring under inner ring and bearing；By the way that semi-cylindrical hill ring is arranged on ring flat-plate, opened on annular groove
If semicircle annular groove so that in bearing rotation process, the concentricity tolerance of bearing outer ring and bearing inner race is small, and rotating effect is good,
Allomeric function is perfect, highly practical.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention；
Fig. 2 is the internal structure schematic diagram of the present invention.
Specific implementation mode
The present invention is further described with preferred embodiment below in conjunction with the accompanying drawings.
Shown in Fig. 1 to 2, a kind of full ball involved by the present embodiment fills full-ceramic bearing, including bearing outer ring 1, axis
Inner ring 2 and the rolling element 3 between bearing outer ring 1 and bearing inner race 2 are held, the bearing inner race 2 is by inner ring on bearing 21
It is formed with inner ring under bearing 22, simplifies the installation process of rolling element 3, increase the load-carrying ability of bearing, added convenient for rolling element 3,
Reduce the abrasion to bearing entirety；Bearing block 4 is embedded in the bearing inner race 2, bearing block 4, which has, to be protruded from the bearing
The ear 41 of 2 upper surfaces is enclosed, ear 41 is fixed in 2 upper surface of the bearing inner race by pressing, and the bearing block 4, which also has, to be supported
It is connected on the ring flat-plate 42 of 2 lower face of bearing inner race, the ring equal with 42 outer diameter of ring flat-plate is offered on the lower face of the bearing outer ring 1
Shape slot 11, ring flat-plate 42 are embedded in the annular groove 11, and 42 upper surface of ring flat-plate is bonded 11 cell wall of annular groove so that bearing
When inner ring 2 drives bearing block 4 to rotate, the rotation in annular groove 11 simultaneously of ring flat-plate 42, ear 41 is through being riveted on 2 upper end of bearing inner race
Face plays the role of fastening on bearing inner ring 22 under inner ring 21 and bearing；The cooperation of ring flat-plate 42 and annular groove 11, plays and leads
To rotation, the effect of reduction concentricity tolerance.
Further, the annular groove 11 has the semicircle annular groove 12 being opened on bearing outer ring 1, semicircle annular groove 12
Inside it is embedded with the semi-cylindrical hill ring 43 being integrated with the ring flat-plate 42 so that in bearing rotation process, semi-cylindrical hill ring 43
The sliding in the semicircle annular groove 12 will not wear and cause between bearing outer ring 1 and bearing inner race 2 because 3 long-time of rolling element uses
Concentricity becomes larger, and plays the role of concentricity tolerance between stable bearing outer ring 1 and bearing inner race 2, reduces abrasion, and extending bearing makes
Use the service life.
Further, the bearing outer ring 1, bearing inner race 2, rolling element 3 and bearing block 4 are ceramic material so that axis
Holding entirety, there is high temperature resistant, insulation, corrosion resistant feature to apply also for unlubricated occasion, and adaptable, use scope is wide.
The present invention is spliced by being fabricated to bearing inner race by upper and lower two parts, changes the installation technique of rolling element,
It is added convenient for rolling element, reduces the abrasion to bearing；Bearing inner race lower face, upper end ear are abutted by bearing block lower end ring flat-plate
It is riveted on bearing inner race upper surface, plays the role of fastening on bearing inner ring under inner ring and bearing；By the way that half is arranged on ring flat-plate
Circular protrusions ring opens up semicircle annular groove on annular groove so that in bearing rotation process, bearing outer ring is coaxial with bearing inner race
Degree tolerance is small, and rotating effect is good, and allomeric function is perfect, highly practical.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be in the protection domain being defined in the patent claims.
