Abstract
The utility model discloses a nanometer zirconium-oxide ceramic bearing, comprising a ceramic shaft sleeve and a ceramic shaft core. An oil storage tank is arranged in the ceramic shaft sleeve, and a middle hole is arranged in the tail end of the ceramic shaft core. The tail end of the ceramic shaft core is provided with a spline matched with a fanning strip, and the ceramic shaft sleeve and the ceramic shaft core are made of the nanometer zirconium-oxide. Aiming at the prior art, the utility model provides a nanometer zirconium-oxide ceramic bearing, and in the use process it can not generate the problems of big noise, no-oil storage, easiness for heating, no-abrasion-resistance and easiness for fracture which are caused by the high-speed running, besides, it has characteristics of corrosion resistance, low heating, no magnetism, long service life, etc. The utility model is suitable for the severe environment, such as the acidic environment and the easy oxidation environment, etc.
Description
[technical field]
The utility model relates to a kind of nanometer zirconium oxide ceramic bearing.
[background technique]
At present, common bearing adopts stainless steel and copper material group to being used more, during high speed operation, this bearing is because of problem of materials own, produce not wear-resisting, problems such as noise big, easy heating, people begin to consider bearing material is improved, such as ceramic bearing.But ceramic bearing is frangible, and because ceramic bearing high density and high hardness, make its processing very difficult, it is little easily to produce big centre, two as trepanning, and can not store lubricant oil, and the contact of main shaft in use can only be a contact, noise is bigger, the design of axle core also has defective, and easy-rupturing combines with flabellum and easily to skid and come off.
In order to address the above problem, the utility model has carried out useful improvement.
[summary of the invention]
The purpose of this utility model is to overcome and solve the problem that the nanometer zirconium oxide ceramic bearing in use produces noise, not oil storage, easy-rupturing, a kind of low noise is provided, has hanged down heating, friction is little, the life-span long and is applicable to the nanometer zirconium oxide ceramic bearing of working as under the rugged environment such as acid, easy oxidation.
The purpose of this utility model is achieved in that
A kind of nanometer zirconium oxide ceramic bearing is characterized in that comprising Ceramic shaft sleeve and ceramic shaft core, is provided with oil storage tank in the Ceramic shaft sleeve, deep hole in the middle of being provided with in ceramic shaft core one end;
Aforesaid a kind of nanometer zirconium oxide ceramic bearing is characterized in that the tail end of described ceramic shaft core is provided with the spline that cooperates with fanning strip;
Aforesaid a kind of nanometer zirconium oxide ceramic bearing is characterized in that described Ceramic shaft sleeve and ceramic shaft core make by nano oxidized zirconia material.
The utility model compared with prior art has following advantage:
1, solves the little problem in big centre, two of Ceramic shaft sleeve, the original point of Ceramic shaft sleeve and ceramic shaft core has been contacted become two end in contact, solved noise problem and heating problem.
2, because the existence of oil storage tank in the middle of the Ceramic shaft sleeve to the long preservation of oil, makes the long-term break-in of Ceramic shaft sleeve and ceramic shaft core very favourable, reduce friction, reduced heating value, made the Ceramic shaft sleeve operation more steady, thereby improved the quality of product.
3, the intermediate hole that is provided with in the ceramic shaft core tail end has then improved ceramic shaping characteristic, thereby has increased axle core integral intensity and toughness widely, makes not easy-rupturing of ceramic shaft core, has prolonged the life-span of ceramic shaft core.
4, since the material of ceramic bearing make by nano zircite, have the nano zircite life-span long, wear-resisting, at a high speed, characteristic such as corrosion-resistant, nonmagnetic, and be applicable to as working under the rugged environment such as acid, easy oxidation.

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
Fig. 1 is the sectional view of Ceramic shaft sleeve in the utility model;
Fig. 2 is the left view of ceramic shaft core in the utility model;
Fig. 3 is the sectional view of Fig. 2 A-A;
Fig. 4 partly cuts open figure for Fig. 2's;
Sectional view when Fig. 5 uses with micro fan for this nanometer zirconium oxide ceramic bearing.
In the accompanying drawing: 1, Ceramic shaft sleeve, 2, ceramic shaft core, 3, oil storage tank,
4, middle deep hole, 5, spline.
[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
A kind of nanometer zirconium oxide ceramic bearing comprises Ceramic shaft sleeve 1 and ceramic shaft core 2, is provided with oil storage tank 3 in the Ceramic shaft sleeve 1, deep hole 4 in the middle of being provided with in ceramic shaft core 2 one ends, and the tail end of ceramic shaft core 2 is provided with the spline 5 that cooperates with fanning strip.
Ceramic shaft sleeve 1 and ceramic shaft core 2 are made by nano oxidized zirconia material.
The nanometer zirconium oxide ceramic bearing can be applicable to aspects such as micro fan, during operation, ceramic shaft core 2 rotates along with running up of micro fan, because the existence of oil storage tank 5 in the middle of the Ceramic shaft sleeve 1, long preservation to oil, make Ceramic shaft sleeve 1 very favourable with the long-term break-in of ceramic shaft core 2, reduced friction, reduced heating value, it is more steady to allow ceramic shaft core 2 move in Ceramic shaft sleeve 1, and is arranged on the middle deep hole 4 in the tail end, then improved ceramic shaping characteristic, thereby strengthened ceramic shaft core 2 integral intensity and toughness widely, made not easy-rupturing of ceramic shaft core 2, prolonged the life-span of ceramic shaft core 2.5 of splines on ceramic shaft core 2 tail ends have solved the problem that ceramic shaft core 2 and flabellum skid and come off, also increased the intensity of ceramic shaft core 2 itself, and the material of Ceramic shaft sleeve 1 and ceramic shaft core 2 is made by nano zircite, have nano zircite high speed, wear-resisting, corrosion-resistant, low heating, non-magnetic characteristics, be applicable to as rugged environment such as acid, easy oxidations.The nanometer zirconium oxide ceramic bearing can be applicable to aspects such as micro fan and this bearing, uses very extensive.
