Abstract

The utility model discloses a ceramic rolling bearing which consists of an outer ring (1), an inner ring (3) and a ceramic rolling body (2). The ceramic rolling body (2) is installed between the outer ring (1) and the inner ring (3). The rolling bearing of the utility model adopts the outer ring, the inner ring and the rolling body, through the ceramic characteristics of high temperature resistance, low temperature resistance, abrasion resistance, no magnetism, good insulation performance and chemical corrosion resistance, the utility model satisfies the using requirements of the rolling bearing under the particular environment of high temperature, low temperature, high speed rotation, magnetic field insulation, and chemical corrosion, etc, and solves the using problem that prior metal rolling bearings can be used under the particular environment.

Description

Ceramic rolling bearing

Technical field

The utility model relates to a kind of bearing, especially a kind of ceramic rolling bearing.

Background technique

Our rolling bearing of using is the rolling bearing of metal material generally speaking, but under some particular surroundings, such as high temperature, low cold, runs up, the magnetic field insulation, and chemical corrosion etc., the rolling bearing of metal often can not satisfy usage requirement.

Summary of the invention

The purpose of this utility model is: providing a kind of can run up at high temperature, low cold, the magnetic field insulation, and the ceramic rolling bearing that uses under the particular surroundingss such as chemical corrosion, thus overcome the deficiencies in the prior art.

The utility model is to constitute like this: it is made of the rolling element (2) of outer ring (1), inner ring (3) and ceramic material, and the rolling element of ceramic material (2) is contained between outer ring (1) and the inner ring (3).

Outer ring in above-mentioned (1) can be the outer ring of ceramic material.

Inner ring in above-mentioned (3) also can be the inner ring of ceramic material.

Rolling element in aforementioned (2) is cylinder rolling element, circular cone rolling element or spherial rolling body.

Pottery in aforementioned is zirconium oxide, silicon carbide or silicon nitride.

Compared with prior art, rolling bearing of the present utility model adopts outer ring, inner ring and the rolling element of ceramic material, utilize pottery high temperature resistant, anti-low cold, wear-resistant, nonmagnetic, the characteristic of good insulating and resistance to chemical attack, satisfy rolling bearing at high temperature, low cold, run up the magnetic field insulation, usage requirement under the particular surroundingss such as chemical corrosion has solved the problem that the rolling bearing of existing metal material can't fine use under above-mentioned particular surroundings.

Description of drawings

Accompanying drawing 1 is the structural representation of cylinder rolling element for the utility model;

Accompanying drawing 2 is the structural representation of circular cone rolling element for the utility model;

Accompanying drawing 3 is the structural representation of spherial rolling body for the utility model.

Embodiment

Embodiment of the present utility model: as shown in Figure 1, it is made of outer ring 1, the inner ring 3 of ceramic material and the rolling element 2 of ceramic material of the ceramic material that ceramic making such as adopting zirconium oxide, silicon carbide or silicon nitride forms, and rolling element 2 is installed between outer ring 1 and the inner ring 3.Because the fragility of stupalith is big, not shock-resistant load.Crushing resistance and resistance to shock loads for the rolling element 2, outer ring 1 and the inner ring 3 that increase ceramic material, remedy the fragility of pottery, rolling element 2 of the present utility model adopts cylinder rolling element, circular cone rolling element (as shown in Figure 2) or spherial rolling body (as shown in Figure 3).

In above-mentioned, except that rolling element 2 is the ceramic material, outer ring 1, inner ring 3 can also all adopt metal material, and perhaps one of them adopts metal material.

Claims

1. ceramic rolling bearing is characterized in that: it is made of the rolling element (2) of outer ring (1), inner ring (3) and ceramic material, and the rolling element of ceramic material (2) is contained between outer ring (1) and the inner ring (3).

2. ceramic rolling bearing according to claim 1 is characterized in that: outer ring (1) is the outer ring of ceramic material.

3. ceramic rolling bearing according to claim 1 is characterized in that: inner ring (3) is the inner ring of ceramic material.

4. ceramic rolling bearing according to claim 1 is characterized in that: rolling element (2) is cylinder rolling element, circular cone rolling element or spherial rolling body.
