Description
Technical field
The utility model relates to a kind of bearings, more specifically, it relates to which a kind of full ball fills full-ceramic bearing.
Background technique
Existing bearing generally comprises bearing outer ring, rolling element and integrated bearing inner race, in the process of production and processing,
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, influences 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 utility model proposes a kind of full balls to fill
Full-ceramic bearing.
Utility model content
The purpose of the utility model is to overcome above-mentioned deficiency in the prior art, a kind of full ball is provided and fills full ceramic shaft
Hold, which has the characteristics that rolling element install convenient, and after the completion of installing additional bearing outer ring and bearing inner race concentricity tolerance
Small, rotating effect is good.
In order to solve the above technical problems, purpose of the utility model is realized as follows: one involved in the utility model
The full ball of kind fills full-ceramic bearing, including bearing outer ring, bearing inner race and the rolling being mounted between bearing outer ring and bearing inner race
Body, the bearing inner race are made of inner ring under inner ring on bearing and bearing, and bearing block, bearing block are embedded in the bearing inner race
With the ear for protruding from the bearing inner race upper surface, ear is fixed in the bearing inner race upper surface by pressing, described
Bearing block also has the ring flat-plate for being connected to bearing inner race lower end surface, offers on the lower end surface of the bearing outer ring and ring flat-plate outer diameter
Equal annular groove, ring flat-plate are embedded in the annular groove, and the ring flat-plate upper surface fitting annular groove groove wall.
The utility model is further arranged to: the annular groove has the semicircle annular groove being provided on bearing outer ring, partly
The semi-cylindrical hill ring being integrated with the ring flat-plate is embedded in circular ring slot.
The utility model is further arranged to: the bearing outer ring, bearing inner race, rolling element and bearing block are ceramic material
Material.
In conclusion the utility model has the following beneficial effects: full ball involved in the utility model fills full ceramic shaft
It holding, being spliced by being fabricated to bearing inner race by upper and lower two parts, change the installation technique of rolling element, add convenient for rolling element
Add, reduces the abrasion to bearing；Bearing inner race lower end surface is abutted by bearing block lower end ring flat-plate, upper end ear is riveted in bearing
Upper surface is enclosed, inner ring under inner ring and bearing is played the role of fastening on bearing；By the way that semi-cylindrical hill ring, ring are arranged on ring flat-plate
Semicircle annular groove is opened up on shape slot, so that the concentricity tolerance of bearing outer ring and bearing inner race is small in bearing rotation process, rotation
Effect is good, and allomeric function is perfect, practical.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic diagram of internal structure of the utility model.
Specific embodiment
The present invention will be further described with preferred embodiment with reference to the accompanying drawing.
Referring to shown in Fig. 1 to 2, a kind of full ball involved in the present embodiment fills full-ceramic bearing, including bearing outer ring 1, axis
The rolling element 3 for holding inner ring 2 and being mounted between bearing outer ring 1 and bearing inner race 2, the bearing inner race 2 is by inner ring 21 on bearing
It is formed with inner ring 22 under bearing, 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 bearing inner race by pressing, and the bearing block 4, which also has, to be supported
The ring flat-plate 42 in 2 lower end surface of bearing inner race is connect, offers the ring equal with 42 outer diameter of ring flat-plate on the lower end surface 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, ring flat-plate 42 rotates in annular groove 11 simultaneously, and ear 41 is 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 provided on bearing outer ring 1, semicircle annular groove 12
It is inside 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
It is slided in semicircle annular groove 12, will not wear because of the use of 3 long-time of rolling element causes between bearing outer ring 1 and bearing inner race 2
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 has high temperature resistant, insulation, and corrosion resistant feature applies also for unlubricated occasion, and adaptable, use scope is wide.
The utility model is spliced by being fabricated to bearing inner race by upper and lower two parts, changes the installation work of rolling element
Skill is added convenient for rolling element, reduces the abrasion to bearing；Bearing inner race lower end surface, upper end are abutted by bearing block lower end ring flat-plate
Ear is riveted on bearing inner race upper surface, plays the role of fastening on bearing inner ring under inner ring and bearing；By being set on ring flat-plate
Semi-cylindrical hill ring is set, semicircle annular groove is opened up on annular groove, so that in bearing rotation process, bearing outer ring and bearing inner race
Concentricity tolerance is small, and rotating effect is good, and allomeric function is perfect, practical.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
