る。 As shown in FIGS. 1 and 2, the rolling bearing has a structure in which balls 3 are disposed between inner and outer rings 1 and 2, and the balls 3 are supported by the surface of a pocket 5 of a cage 4. The self-lubricating cage 4 is made of an organic base material such as plastic impregnated with a solid lubricant such as molybdenum disulfide or graphite, but in order to supplement its strength, it may be woven with inorganic or organic fibers. A cage is used in which woven cloth is impregnated with an organic material and the woven cloth is laminated in a cylindrical shape. FIG. 3 shows a method for manufacturing such a cage, in which a woven fabric 7 impregnated with an organic material is wrapped around a core rod 9 and bonded under heat to obtain a cylindrical woven fabric laminated composite material. It is cut into rings of appropriate width and used for cages. This conventional self-lubricating cage for bearings made of a woven fabric laminated composite material has the following disadvantages. In other words, the self-lubricating property of the cage is determined by the lubricity of the organic material impregnated into the woven fabric, so the self-lubricating property is inferior to a cage made only of an organic base material impregnated with a solid lubricant. .

い。 Based on this, it is thought that it is possible to improve the self-lubricity of conventional cages by adding a solid lubricant to the organic material impregnated into the woven fabric, but the organic material and solid lubricant Due to the difference in density between them, the organic material and solid lubricant separate when impregnated into woven fabric, making it difficult to manufacture.

る。 In addition, in the method of manufacturing a self-lubricating retainer for a bearing made of a laminated composite material reinforced with a cloth woven with inorganic or organic fibers, solid lubrication is applied during the process of manufacturing the laminated composite material. A layer of organic material impregnated with the agent is interposed between the woven fabric layers.
次に、本発明の実施例を第４図から第５図を参

ような外形の保持器が得られる。 Figure 4 shows one example of the manufacturing method of the present invention, and shows a woven fabric impregnated with an organic material such as plastic (a woven fabric made of inorganic fibers such as glass fiber or carbon fiber, or a woven fabric made of organic fibers). A sheet 8 made of an organic material such as plastic impregnated with a solid lubricant such as molybdenum disulfide or graphite is layered on top of the cloth 7' to obtain the desired thickness around the core rod 9'. Wrap it in multiple layers like this. While or after wrapping, the woven fabric 7' and the sheet 8
The two are heat-pressed so that they become one piece. By cutting the resulting cylindrical laminate at desired intervals in a direction perpendicular to its axis and carving out pockets that support the balls, a cage with the external shape shown in Figures 1 and 2 can be obtained. It will be done.
