RETAINER FOR ROLLING BEARING, AND ROLLING BEARING |
摘要 |
It is an object of the present invention to provide a rolling bearing which can be used in conditions in which a DN value is not less than 1,500,000 and an operating temperature is not less than 200°C and which can be securely operated for a sufficiently long period of time without seizing, even though the rolling bearing is used in a dry run state and a cage for the rolling bearing. A cage (1) is formed by molding a carbon fiber composite material composed of a matrix consisting of a high-molecular compound reinforced with a carbon fiber material. The carbon fiber material consists of a bundle of 1000 to 5000 monofilaments, a woven cloth or a unidirectional material consisting of the bundle of the monofilaments. The high-molecular compound is polyimide resin or the like whose glass transition temperature is not less than 200°C after the high-molecular compound thermally hardens. |
