【考案の詳細な説明】
この考案は真空中、高温中および高速のような
条件で使用する転がり軸受に関する。[Detailed Description of the Invention] This invention relates to a rolling bearing used under conditions such as vacuum, high temperature, and high speed.

３と表面に銀被膜４を施した第二のボール５とを
交互に配設し、この第二のボール５の直径を第一
のボール３の直径より少し小さくしている。 Since oil and grease cannot be used in a vacuum, conventional ball bearings used in a vacuum have a first ball 3 between an outer ring 1 and an inner ring 2, and a silver coating 4 on the surface, as shown in Figure 1. The diameter of the second balls 5 is made slightly smaller than the diameter of the first ball 3.

の転動体３に焼付きが生ずる。 Therefore, the silver coating 4 with lubricating performance of the second ball 5 transfers to the surface of the first ball 3, and although the ball bearing has lubricating performance, sufficient lubricating performance cannot be obtained.
The outer ring 1, the inner ring 2, and the first ball 3 are all abrasively worn. Further, since the outer ring 1, the inner ring 2, and the first rolling element 3 are all made of bearing steel, similar materials roll into contact and become so-called friend metals, which causes an adhesion phenomenon. Furthermore, since the outer ring 1, the inner ring 2, and the first rolling element 3 do not have the necessary hardness, oxidized wear particles become trapped, causing the ball bearing to lock. Furthermore, since heat dissipation is not good in a vacuum, the temperature rises and seizure occurs in the outer ring 1, the inner ring 2, and the first rolling element 3.

As No. 3, a silver coating is applied by an ion plating method, a wet plating method, or the like. The inner ring 31 of the ball bearing is made of high-speed steel, and the inner raceway 32 of the inner ring 31 is coated with a silver coating 33 of a material having lubricating properties by ion plating, wet plating, etc. has been done. First rolling elements 41 and second rolling elements 42 are alternately arranged between the outer ring 21 and the inner ring 31, forming a full-spherical ball bearing. Since the first rolling element 41 is a ball made of ceramic, the rolling surface of the first rolling element 41 is made of ceramic, and the second rolling element 42 is made of heat-resistant material such as high-speed steel or stainless steel. It is a ball made of a material with A silver coating is applied to the surface of the second rolling element 42 as a coating 43 of a material having lubricating properties by an ion plating method, a wet plating method, etc. The diameter is slightly smaller than that of the moving body 41.
Therefore, the force applied to the ball bearing acts via the first rolling element 41.

また、第一の転動体４１の直径は第二の転動体
４２の直径と等しくても良く、また第二の転動体
４２は第一の転動体４１より直径が微少量小さく

優れた効果を有する。 According to the rolling bearing of this invention, the outer ring 21 and the inner ring 31 are made of high-speed steel, and the raceways 22 and 32 are coated with a material having lubricating properties.
3 and 33, and the surface of the second rolling element 42 is coated with a coating 43 of a material having lubricating performance. It makes rolling contact with the chisel and has excellent lubrication performance. In addition, since the rolling surface of the first rolling element 41 is made of ceramic, the first rolling element 41 is made of different materials from the outer ring 21 and the inner ring 31, and since the different materials roll into contact with each other, they do not become metal, and the adhesion phenomenon is prevented. Does not occur. Furthermore, since the rolling surface of the first rolling element 41 is made of ceramic, it has sufficient hardness, and since the outer ring 21 and the inner ring 31 are made of high-speed steel, they have the necessary hardness and are free from oxidized wear particles. Prevents jamming and prevents the rolling bearing from locking.
In addition, since the outer ring 21 and the inner ring 31 are made of high-speed steel, they are inexpensive and have heat resistance.
Further, since the rolling surface of the first rolling element 41 is made of ceramic, it has heat resistance, prevents seizure, and has a long life, which has various excellent effects not available in conventional rolling bearings.
