The present invention provides a ball retainer for a rolling bearing that has excellent lubricity, is lightweight, and has low torque.

ッ化黒鉛、金、根、鉛等の固体潤滑剤が用いられる。Oil or grease is generally used to lubricate sliding parts such as rolling bearings. However, when used in places where the use of oil is undesirable, such as in a vacuum or high-temperature atmosphere, when used in places where lubrication is difficult, or under conditions where oil cannot be used, graphite or molybdenum disulfide can be used as a lubricant. Solid lubricants such as , tungsten disulfide, hexagonal boron nitride, Teflon powder, graphite fluoride, gold, root, lead, etc. are used.
しかし、上述した固体潤滑剤のうち、黒鉛は真空中では
潤滑性が不十分であり、テフロン等のプラスチック類や
フッ化黒鉛は耐熱性が不十分である。However, among the solid lubricants mentioned above, graphite has insufficient lubricity in a vacuum, and plastics such as Teflon and fluorinated graphite have insufficient heat resistance.

使用されているが、装置が高価であること等により製品
が高価となり、しかも十分な性能は得られていない。A common method for using solid lubricants is to rub them onto sliding parts. However, when used in the form of a thin film, the wear life of this film is short and excessive wear powder is generated. In addition, methods of forming thin films by ion blasting, sputtering, etc. have also been used, but the equipment is expensive, making the products expensive and, moreover, sufficient performance has not been obtained.
このような問題点を解決するため、自己潤滑性を有する
材料の使用が考えられている。In order to solve these problems, the use of self-lubricating materials has been considered.

たことを特徴とする。゛□The first invention of the present invention is a ball retainer for a rolling bearing, in which at least the sliding contact portion with the balls is made of a material whose main component is glassy carbon, such as glassy carbon alone or a glassy carbon composite material. It is characterized by being configured as

とが望ましい。As the glassy carbon, one obtained by curing and firing a thermosetting resin can be used, and polyacrylonitrile-based, rayon-based, phenol-based, or furan-based resins can be used. In particular, 20% in the state of first 'M condensed proboscis.

ウィスカから選ばれる一種以上のウィスカを含むものを
用いることができる。However, as the glassy carbon composite material, a material containing glassy carbon as a main component and one or more whiskers selected from silicon carbide whiskers, silicon nitride whiskers, graphite whiskers, and alumina whiskers as a reinforcing fiber component can be used. .
ここでいうウィスカとは、固体からの自然成長、蒸気の

度に及ぶものが知られている。ウィスカの最大の特徴は
、結晶内部の転移や欠陥が極めて少ないことであり、皆
無のものもある。このため、ウィスカの強度はその結晶
の理想値に近い。The term "whisker" as used herein refers to a needle-shaped crystal that grows by natural growth from a solid, vapor condensation, chemical reaction, unidirectional solidification of eutectic crystals, electrodeposition, etc., and is also called a whisker crystal. It is known that the thickness ranges from 0.05 μm or less to about 10 μm. The most important feature of whiskers is that they have extremely few dislocations and defects inside the crystal, and some have none at all. Therefore, the whisker strength is close to the ideal value for the crystal.
ウィスカのアスペクト比（太さと長さとの比）には特に
規定はないが、一般にアスペクト比の大きいものほどそ

らには５０以上のウィスカを用いた場合に効果が得られ
た。Although there are no particular regulations regarding the aspect ratio (ratio of thickness to length) of whiskers, generally speaking, the larger the aspect ratio, the greater the strength of the composite material containing the whiskers. In the glassy carbon composite material of the present invention, effects were obtained when whiskers with an aspect ratio of 10 or more, and even 50 or more were used.
ウィスカの含有率は、ガラス状カーボンに対して体積比
で０．００５〜０．２の範囲が望ましく、さらには０．
００５〜０．１の範囲が望ましい。この範囲の場合には

が得られない。また、多すぎる場合には、精密加工性が
低下し、摩擦係数が太き（なってしまう。The content of whiskers is preferably in the range of 0.005 to 0.2 in volume ratio to glassy carbon, and more preferably 0.005 to 0.2.
A range of 0.005 to 0.1 is desirable. In the case of this range, precision machinability, wear resistance, and friction coefficient are excellent. If the content of whiskers is low, no effect can be obtained from mixing. In addition, if the amount is too large, precision machinability decreases and the coefficient of friction becomes large.

ましい。Furthermore, for ball retainers used in high vacuum, etc., one or more fillers selected from molybdenum disulfide, tungsten disulfide, and hexagonal boron nitride are used in the glassy carbon or composite material thereof. This is desirable.

、しかも寿命の長い耐久性を示すことができる。These fillers are materials used as solid lubricants, and all have hexagonal crystal structures. For example, molybdenum disulfide forms an excellent lubricating film by forming folds during sliding, and exhibits an extremely low coefficient of friction when it adheres to metal surfaces. By incorporating such a solid lubricant, it can match the appropriate anti-friction properties of glassy carbon or its composite material, which has high wear resistance, and provide an appropriate source of solid lubricant, while also providing long-life durability. can be shown.
ガラス状カーボンは、自己潤滑性があり、耐熱性および
耐久性に優れ、しかも軽量な材料である。Glassy carbon is a material that is self-lubricating, has excellent heat resistance and durability, and is lightweight.

トルクで動作する。By using this material, low friction, low wear, light weight,
A ball cage for rolling bearings with excellent heat resistance is obtained. This ball holder does not require the use of lubricating oil and operates with low torque even in an atmosphere such as a vacuum where lubricating oil cannot be used.

くなる。The strength of the ball retainer can be increased if a glassy carbon composite material mixed with whiskers is used. Further, when using a composite material in which a filler is mixed into glassy carbon or a composite material of glassy carbon and whiskers, the coefficient of friction of the ball holder becomes extremely small.
