る。However, these sliding members are
All have excellent heat resistance, but under dry friction conditions there are problems with friction and wear characteristics, mechanical strength,
In particular, there are problems in that impact resistance is difficult, the compatibility with the mating material is not always good, and that the function cannot be sufficiently exerted against minute slip. In order to solve such a problem, for example, US Pat.
As disclosed in Japanese Patent No. 137,373 and Japanese Patent Publication No. 44-23966, it has been developed to manufacture a sliding member by molding expanded graphite obtained by specially treating graphite with a reinforcing material. However, this sliding member has heat resistance and excellent compatibility with the mating material, is rather high compared to ordinary graphite, and in addition, it often has abnormalities during sliding in dry friction. It has the drawback of producing fricatives. In addition, a sliding member obtained by molding a heat-resistant material such as mica or asbestos together with a reinforcing material is also known, but these have similar problems.

態となるので、注意を必要とする。 2. Properties of Sliding Member Next, properties and characteristics of the sliding member obtained through the above steps (a) and (b) will be described. The area ratio of the metal part exposed on the surface of the sliding member, the fluororesin thread part and the heat resistant material part is 10 to 30% for the metal part, 10 to 30% for the fluororesin thread part and 40 to 80% for the heat resistant material.
Is the range. This area ratio is (1) the diameter of the fine metal wires that make up the sliding surface material (2) the number of combinations of fluororesin threads to the fine metal wires (3) the denier number of fluororesin threads (4) the cross section of fluororesin threads Shape (5) Difference in whether fluororesin yarn is single yarn or spun yarn (6) In the case of spinning yarn, the number of filaments and the strength of twist (7) Molding pressure at the time of molding the sliding member, etc. It will be different depending on the type. For example, in the single yarn and the spun yarn, even if the yarn has the same denier number, the sliding member obtained by using the latter sliding surface material has a larger area ratio of the fluororesin yarn portion. . This is because "unraveling" occurs in the spinning during compression molding, and if "unraveling" becomes significant, the sliding surface becomes fluffy, so caution is required.

積割合は、約１５％であった。A request for changing the area ratio of the fluororesin yarn portion should be dealt with by keeping the wire diameter of the thin metal wire and the molding pressure constant and changing the denier number and the number of combinations of the fluororesin yarn. You can As an example, one fine metal wire having a diameter of 0.29 mm is combined with two 400 denier tetrafluoroethylene resin single yarns and co-knitted at the 3 mm to form a sliding surface material. Then, the sliding surface material 3 is formed on the sheet-shaped heat-resistant material of the laminated body formed by stacking the sheet-shaped heat-resistant material 4 by projecting the sheet-shaped heat-resistant material 4 from one end of the reinforcing material 5 made of wire mesh in the longitudinal direction. After stacking, the cylindrical base material 6 formed by spirally winding from one end so that the sliding surface material 3 is located at the outermost periphery is inserted into the mold, and the cylindrical base material 6 is inserted in the axial direction of the base material 2. .
The area ratio of the tetrafluoroethylene resin yarn portion on the sliding surface of the sliding member obtained by compression molding at a pressure of 5 kg / cm 2 was 25%. On the other hand, 0.29 mm
One fine metal wire having a wire diameter of 4 is combined with one 400 denier tetrafluoroethylene resin single yarn and co-knitted at the 3 mm to form a sliding surface material. The area ratio of the tetrafluoroethylene resin thread portion on the sliding surface of the sliding member obtained by using the same conditions as above was about 15%.

防止するという効果をもたらす。Here, the function and effect of the fluororesin yarn will be described. Fluorine resin, especially tetrafluoroethylene resin is a substance having a very small coefficient of friction, and it is well known that it is used as a solid lubricant like graphite and molybdenum disulfide. Fluorocarbon resin (a) There is no difference between static friction coefficient and dynamic friction coefficient. (B) Many other plastic materials show "negative resistance (the curve of friction coefficient shows It does not show "indicating a gradient)" but also exhibits a behavior (which can be called a characteristic) such as taking a positive gradient. The characteristics (a) and (b) bring about an effect of preventing the generation of frictional noise without causing "stick slip" during friction.

る。Further, the fluororesin in the form of a fluororesin thread arranged on the sliding surface has higher abrasion resistance than the case where the fluororesin is powder-coated on the sliding surface (the prior art). It has the advantage of being excellent. This is because the application in the form of a thread has a strong strength due to the orientation of the fluororesin molecules, which has a favorable effect on the wear resistance.

In addition, the fluororesin thread exposed on the sliding surface is a drawback of what was formed by coating the above-mentioned prior art fluororesin, that is, the fluororesin does not fall off from the sliding surface, and it remains for a long time under dry friction conditions.

It is a sliding member created based on the technology of Japanese Patent No. 0701. That is, the same stainless steel wire as in Example 1 was braided to form a net, which was used as a reinforcing material. On the other hand, as a sheet-shaped heat-resistant material, a tetrafluoride ethylene resin having a thickness of 0.1 mm was applied to one surface of an expanded graphite sheet by a certain length (one winding time). Next, this expanded graphite sheet is superposed on a reinforcing material, and wound in a spiral shape so that the adhered surface of the tetrafluoroethylene resin is located inside to form a tubular base material, and this tubular base material is implemented. Molding was performed in the same manner as in Example 1 to obtain a cylindrical sliding member. In the thus obtained sliding member, an adhered surface of tetrafluoroethylene resin appeared on the inner peripheral surface, and this inner peripheral surface was used as the sliding surface.

In particular, when the friction coefficient and the wear amount are evaluated together, it is clear that they show balanced performance. The sliding member of Comparative Example 2 exhibited the same performance as the sliding member of the present invention in terms of friction coefficient and wear amount, but part of the tetrafluoroethylene resin on the sliding surface fell off as the test progressed. However, at that site, friction with expanded graphite was transferred, and abnormal noise was observed.
