Abstract
The present invention relates to a kind of ceramic bearings, and including inner ring, outer ring and ceramic balls, the size of the inner ring and outer ring is consistent with national standard, can coordinate with standard axle, it is characterised in that：The interior raceway being assemblied between inner ring and outer ring and outer raceway are further included, the outer raceway is semi-open type, and the ceramic balls are assemblied in the space that interior raceway and outer raceway are formed；The ceramic balls are standard rolling bearing ball size element or the consistent established line bearing ball size element of dimensional discrepancy.Due to the adoption of the above technical scheme, take full advantage of ceramic self-lubricating, high abrasion, etch-proof feature, without using lubricating oil, without sealing, and using the design of interior raceway and the outer raceway of semi-open type, without carrying out retrofit to ceramic balls, the ceramic balls consistent to dimensional discrepancy are applicable, the size requirement to ceramic balls is reduced, improves the utilization rate of the ball of ceramic post sintering, it is at low cost.
Description
【Technical field】
The present invention relates to field of bearings, more particularly, to a kind of ceramic bearing.
【Background technology】
Bearing is that component that is fixed and reducing load coefficient of friction is played in mechanical transmission course, is in contemporary mechanical equipment
A kind of very important parts, its precision, performance, life and reliability are to the precision, performance, life and reliability of host
Conclusive effect is played, current market sales of bearing is manufactured usually using metal material, and metal bearing is highly prone to
Environmental corrosion and get rusty, actual effect is influenced, so needing to add lubricating oil to reduce friction and prevent corrosion of metal, but dust class object
Matter bonded by lubricating oil after as bearing is rotated into inside it, the greasy dirt of long time integration can cause ball or raceway secondary
Abrasion or occur directly it is stuck, for problems, it will usually using sealing by the way of solve, prevent foreign matter enter bearing and
Lubricating oil mixing bonds, but the encapsulation process that bearing difficult to realize is stringent, is still present with bearing in the case where dust is larger
The phenomenon that being worn by foreign matter or be stuck；Ceramic bearing is also generated accordingly for problems, really in performance
Better than metal bearing, and ceramic bearing has the characteristics of self-lubricating, without adding lubricating oil, so without worrying the foreign matters such as dust
It is caused to wear, but ceramic material is easy to precision processing without image of Buddha metal material, there are rulers in sintering process for ceramics
Very little error, so for assembly precision, it is necessary to carry out fine attrition process to ceramic balls and raceway, and this process needs to consume
The higher cost of expense could be realized, also, the ceramic balls in addition to standard size are waste product, therefore qualified yield rate is low,
It can not be widely applied.
【The content of the invention】
It is an object of the invention to provide it is a kind of using ceramic self-lubricating the characteristics of, using the special of interior raceway and outer raceway
Design the ceramic bearing formed, it is intended to solve metal bearing and need to add lubricating oil dust class substance is caused to enter Bearing inner to axis
The problem of manufacturing into secondary abrasion or directly stuck appearance and ceramic bearing complex manufacturing technology and Expenses Cost is high asks
Topic.
The present invention is achieved in that a kind of ceramic bearing, including inner ring, outer ring and ceramic balls, the inner ring and outer
The size of circle is consistent with national standard, can coordinate with standard axle, further includes the interior raceway that is assemblied between inner ring and outer ring and outer
Raceway, the outer raceway are semi-open type structure, and the ceramic balls are assemblied in the space that interior raceway and outer raceway are formed；It is described
Ceramic balls are standard rolling bearing ball size element or the consistent established line bearing ball size element of dimensional discrepancy.
The present invention further technical solution be：The scope of the ceramic balls dimensional discrepancy is in standard rolling bearing ball size
Between ± 1mm.
The present invention further technical solution be：The inner ring and outer ring are metal material.
The beneficial effects of the invention are as follows：Due to the adoption of the above technical scheme, self-lubricating, the height for taking full advantage of ceramics are resistance to
Mill, etch-proof feature, without using lubricating oil, without sealing, and using the design of interior raceway and the outer raceway of semi-open type, nothing
Retrofit need to be carried out to ceramic balls, the ceramic balls consistent to dimensional discrepancy are applicable, reduce to ceramic balls
Size requirement, improves the utilization rate of the ball of ceramic post sintering, at low cost.
【Description of the drawings】
Fig. 1 is the structure diagram of ceramic bearing made from the method for the present invention；
Fig. 2 is the A-A cross-sectional views of Fig. 1.
In figure：
Raceway in 1-, the outer raceways of 2-, 3- ceramic balls, 4- inner rings, 5- outer rings.
【Specific embodiment】
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described further.
As depicted in figs. 1 and 2, a kind of ceramic bearing, including inner ring 4, outer ring 5 and ceramic balls 3, the inner ring 4 and outer
The size of circle 5 is consistent with national standard, can coordinate with standard axle, further include the interior raceway 1 being assemblied between inner ring 4 and outer ring 5
With outer raceway 2, the outer raceway 2 is semi-open type structure, and the ceramic balls 3 are assemblied in the sky that interior raceway 1 and outer raceway 2 are formed
Between in；The ceramic balls 3 are standard rolling bearing ball size element or the consistent established line bearing ball size element of dimensional discrepancy.
Since interior raceway 1 and the outer raceway 2 of semi-open type have certain adaptivity, only need 3 size of ceramic balls consistent ---
Ensure its axial stability, and without ball size is needed to be necessary for standard size as traditional bearing --- ensure its axial direction
And radial stability.
Preferably, the scope of 3 dimensional discrepancy of ceramic balls is between standard rolling bearing ball size ± 1mm.In this model
The bearing radial stability that size in enclosing is formed can perfectly the adaptivity of inner raceway 1 and the outer raceway 2 of semi-open type come
It adjusts and completes, meanwhile, the design requirement of interior raceway 1 and outer raceway 2 is also reduced accordingly.
Preferably, the inner ring 4 and outer ring 5 are metal material.Can so reduce to a greater extent ceramic bearing into
Originally and produce, using difficulty.
Due to the adoption of the above technical scheme, ceramic self-lubricating, high abrasion, etch-proof feature are taken full advantage of, without
Using lubricating oil, without sealing, and using the design of interior raceway and the outer raceway of semi-open type, without carrying out finely adding to ball
Work, the ball consistent to dimensional discrepancy is applicable, reduces the size requirement to ceramic balls, improves the rolling of ceramic post sintering
The utilization rate of pearl, it is at low cost.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
