Abstract
The invention relates to a ceramic bearing which comprises an inner ring, an outer ring and ceramic balls. The dimension of the inner ring and the dimension of the outer ring are identical with the national standards, and the inner ring and the outer ring can be matched with standard shafts. The ceramic bearing is characterized by further comprising an inner rolling path and an outer rolling path which are assembled between the inner ring and the outer ring; the outer roller path is in a semi-opening manner, and the ceramic balls are assembly in the space formed by the inner rolling path and the outer rolling path; and the ceramic balls are standard bearing ball dimension parts or non-standard bearing ball dimension parts identical in dimension deviation. By means of the technical scheme, the features of self-lubrication, high abrasion resistance and corrosion resistance of ceramic are fully utilized, lubricating oil is not needed, and sealing is not needed; in addition, the design of the inner rolling path and the semi-opening type outer rolling path is adopted, the ceramic balls do not need to be elaborately processed, the inner rolling path and the semi-opening type outer rolling path are suitable for the ceramic balls identical in dimension deviation, the dimension requirement for the ceramic balls is lowered, the utilization rate of the ceramic sintered balls is increased, and the cost is low.
Description
[
technical field]
The present invention relates to field of bearings, especially relate to a kind of ceramic bearing.
[
background technique]
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor, a kind of very important component in contemporary machinery, its precision, performance, life and reliability is to the precision of main frame, performance, life and reliability plays conclusive effect, the bearing sold in the market uses metallic material to manufacture usually, metal bearing is very easily subject to environmental corrosion and gets rusty, affect actual effect, so need to add lubricant oil to reduce friction and to prevent corrosion of metal, but enter its inside along with bearing rotates after the lubricated caking of oil of dust class material, the greasy dirt of long time integration can cause secondary to wear and tear to ball or raceway or occur directly stuck, for problems, usually the mode of sealing can be adopted to solve, prevent foreign matter from entering Bearing and lubrication oil mixing bonding, but be difficult to realize the strict encapsulation process of bearing, still there will be bearing to be worn and torn by foreign matter or stuck phenomenon when dust is larger, also ceramic bearing is created accordingly for problems, usability is better than metal bearing really, and ceramic bearing has the feature of selflubricating, lubricant oil need not be added, so do not worry that the foreign matters such as dust cause wearing and tearing to it, but stupalith cannot be easy to precision processing as metallic material, all size error is there is in pottery in sintering process, so in order to assembly precision, need to carry out meticulous abrasive machining to ceramic balls and raceway, and this process need expends higher cost could realize, and, ceramic balls except standard measure is waste product, therefore qualified yield rate is low, cannot spread.
[
summary of the invention]
The object of the present invention is to provide a kind of feature utilizing ceramic selflubricating, the ceramic bearing that in adopting, the particular design of raceway and outer raceway is formed, be intended to solve metal bearing need add lubricant oil and cause dust class material to enter Bearing inner causing secondary wear and tear or occur directly stuck problem to bearing, and ceramic bearing complex manufacturing technology and the high problem of Expenses Cost.
The present invention realizes like this, a kind of ceramic bearing, comprise inner ring, outer ring and ceramic balls, described inner ring is consistent with NBS with the size of outer ring, can coordinate with standard axle, also comprise and be assemblied in interior raceway between inner ring and outer ring and outer raceway, described outer raceway is semi-open type structure, and described ceramic balls is assemblied in the space that interior raceway and outer raceway formed; Described ceramic balls is the established line bearing ball size element that standard rolling bearing ball size element or size deviation are consistent.
Further technological scheme of the present invention is: the scope of described ceramic balls size deviation is between standard rolling bearing ball size ± 1mm.
Further technological scheme of the present invention is: described inner ring and outer ring are metallic material.
The invention has the beneficial effects as follows: owing to adopting technique scheme, take full advantage of the selflubricating of pottery, high abrasion, etch-proof feature, without the need to using lubricant oil, without the need to sealing, and adopt the design of interior raceway and the outer raceway of semi-open type, without the need to carrying out retrofit to ceramic balls, the ceramic balls consistent to size deviation is all applicable, reduce the size requirement to ceramic balls, improve the utilization ratio of the ball of ceramic post sintering, cost is low.

[
embodiment]
Below in conjunction with the drawings and the specific embodiments, the present invention is described further.
As depicted in figs. 1 and 2, a kind of ceramic bearing, comprise inner ring 4, outer ring 5 and ceramic balls 3, described inner ring 4 is consistent with NBS with the size of outer ring 5, can coordinate with standard axle, also comprise and be assemblied in interior raceway 1 between inner ring 4 and outer ring 5 and outer raceway 2, described outer raceway 2 is semi-open type structure, and described ceramic balls 3 is assemblied in the space that interior raceway 1 and outer raceway 2 formed; Described ceramic balls 3 is the established line bearing ball size element that standard rolling bearing ball size element or size deviation are consistent.Because the outer raceway 2 of interior raceway 1 and semi-open type has certain adaptivity, therefore---ensure its axial stability, and ball size need not be needed as traditional bearing to be necessary for standard measure---ensures its axis and radial stability only to need ceramic balls 3 consistent size.
Preferably, the scope of described ceramic balls 3 size deviation is between standard rolling bearing ball size ± 1mm.The bearing radial stability that size within the scope of this is formed, the adaptivity of perfect inner raceway 1 and the outer raceway 2 of semi-open type can regulate, meanwhile, has also reduced the designing requirement of interior raceway 1 and outer raceway 2 accordingly.
Preferably, described inner ring 4 and outer ring 5 are metallic material.The cost of ceramic bearing and production, application difficulty can be reduced so to a greater extent.
Owing to adopting technique scheme, take full advantage of the selflubricating of pottery, high abrasion, etch-proof feature, without the need to using lubricant oil, without the need to sealing, and adopt the design of interior raceway and the outer raceway of semi-open type, without the need to carrying out retrofit to ball, the ball consistent to size deviation is all applicable, reduce the size requirement to ceramic balls, improve the utilization ratio of the ball of ceramic post sintering, cost is low.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
