The present invention relates to a method for manufacturing a glass fiber reinforced composite material bearing retainer used as an improved product such as a polytetrafluoroethylene (PTFE) bearing retainer reinforced with glass woven cloth.

For example, bearings for space equipment such as rocket engines are often used in special environments such as extremely low temperatures and ultra-high vacuums, so commonly used oils and greases are used as bearing lubricants. Therefore, solid lubricants made of self-lubricating materials are very often used in bearing cages for rolling bearings and the like.

る。 When a solid lubricant is used in the bearing cage in this way, when the bearing rotates, the steel balls come into contact with the pocket holes in the bearing cage, the lubricant is transferred to the steel balls, and then the lubricant is transferred from the steel balls to the inner and outer rings. The lubricant is transferred to the raceway surface of
Furthermore, lubrication is achieved by forming a thin film of solid lubricant over the entire friction surface.

ている。 In particular, bearing cages used with high DN values (bearing inner diameter x rotational speed) such as liquid hydrogen or liquid oxygen turbo pumps need to be small, lightweight, and have great strength, and are made of glass woven material. A glass fiber-reinforced composite material is often used, which is formed by impregnating PTFE with PTFE and rolling it into a pipe shape, and this type of material is also used in cryogenic turbo pump bearing retainers in other countries as well. Most commonly used.

Incidentally, the bearing retainer is formed by machining pocket holes in the retainer material, and as shown in FIGS. 10 and 11, the pocket holes are formed in the bearing retainer material 12 made of a glass fiber reinforced composite material. 13 is formed by machining to form the bearing cage 11, the glass fibers are also cut during the machining, so the surface of the pocket hole 13 after machining is coated with a base material made of PTFE. 14 and hard glass fibers 15 coexist, and depending on the processing conditions, the glass fibers 15 may become stronger than the base material 14, as shown in the photographic drawings showing enlarged views of the machined surface of the pocket hole in Figs. Sometimes it jumps out.

When the bearing 16 is assembled and used, when the bearing rotates and the steel balls 17 come into contact with the inner surface of the pocket hole 13, they cannot make much contact with the PTFE base material 14, which is a lubricant, and come into contact with the glass fiber 15, causing damage. As a result, the lubricant does not transfer much from the base material 14, and the broken glass fibers 15 may also become entangled during the lubricant transfer. In addition, in Figure 12, 1
8 is an outer ring of the bearing, and 19 is an inner ring.
この状態で軸受動作を続けると、潤滑不足で軸

し、この現象が軸受の寿命を短縮していた。 If the bearing continues to operate in this condition, the bearing will generate heat due to lack of lubrication, which in the worst case scenario will cause smearing, which shortens the life of the bearing.

In order to solve the above-mentioned problems, the present invention has been developed by machining a bearing cage material made of a glass fiber reinforced composite material made of a self-lubricating material and glass fibers to remove glass fibers from machined surfaces such as pocket holes and guide surfaces. , dissolve and remove to an appropriate depth with a surface treatment agent,
Bearing cages are manufactured to ensure good contact between steel balls and other lubricating materials.

も用いることができる。 Examples of glass fiber-reinforced composite materials include Teflon resins such as PTFE reinforced with woven glass fabric, but materials combined with woven glass fabric have self-lubricating properties and are stable at high temperatures. Other materials can also be used as long as they do not react with the surface treatment agent, such as hydrofluoric acid, used for dissolution and removal.

で処理することも可能である。 Hydrofluoric acid is used as a surface treatment agent to dissolve glass fibers on processed surfaces such as pocket hole surfaces and guide surfaces. Commercially available hydrofluoric acid (46%) can be used as hydrofluoric acid, but
The concentration may be any concentration that can dissolve glass. To dissolve the glass fibers on the machined surface, the bearing cage material made of glass fiber reinforced composite material is machined and then immersed in hydrofluoric acid. As a result, the surface of the bearing cage is uniformly treated, and the glass fibers on the entire surface are uniformly dissolved and removed. Since the amount of glass fibers to be dissolved and removed is proportional to the processing time, the processing time is increased if it is necessary to dissolve and remove the glass fibers deep into the processed surface. Note that it is also possible to treat only the machined portion with hydrofluoric acid instead of the entire surface of the machined bearing cage.

いので、その構造強度は低下しない。
As mentioned above, the glass fibers on the processed surface are removed by dissolving them using a surface treatment agent such as hydrofluoric acid, so the glass fibers on the processed surface can be removed uniformly and easily. Self-lubricating materials such as PTFE, which is the base material of fiber-reinforced composite bearing cages, are extremely stable and do not react with surface treatment agents such as hydrofluoric acid during the glass fiber melting process, which increases their structural strength. does not decrease.

る。 Therefore, when a glass fiber-reinforced composite material bearing cage made by such a manufacturing method is applied to, for example, a space equipment bearing used in a special environment, the structural strength of the bearing cage will not be reduced. In addition, the steel balls of the bearing can be contacted only with self-lubricating materials such as PTFE, and therefore the lubricant can be easily supplied, improving the lubricity of the bearing and greatly extending its service life. The reliability of space equipment such as turbo pumps can be significantly improved.

In the figure, 1 is a bearing cage made of a glass fiber reinforced PTFE composite material formed by impregnating a glass woven cloth with self-lubricating PTFE, and the cage 1 has pocket holes 2 for holding steel balls. The pocket hole 2 has been drilled through processing, and the glass fibers on the surface of the pocket hole 2 have been melted and removed, leaving a large number of microholes formed on the surface.

First, a short cylindrical bearing retainer material is formed by molding using glass fiber reinforced PTFE composite material. Next, the outer periphery of the material is ground to a predetermined outer diameter, and then a large number of pocket holes for holding steel balls are machined along the periphery.

かる。 The machined bearing cage material is then immersed in commercially available 46% hydrofluoric acid for 5 minutes to provide the required amount of lubricant.
Dissolve and remove glass fibers up to the depth of the PTFE layer. Note that since the amount of glass fiber dissolved is proportional to the time and temperature of immersion in hydrofluoric acid, the depth to which the glass fiber is dissolved and removed can be determined by the treatment time and temperature. For example, when using 46% hydrofluoric acid, it takes 8 to 10 minutes at room temperature to dissolve and remove 100 μm.
