Description of the Related Art Graphite bearings have conventionally been used as sliding materials that can be used from room temperature to high temperatures, and these are used for sliding members and sliding bearings. Graphite bearings have excellent chemical resistance and self-lubricating properties, so they can be used as sliding materials up to high temperatures of about 400 to 500 ° C, but they have major drawbacks such as high porosity and poor mechanical strength. ing.

In this case, the heat resistance temperature is 400 to 500 ° C. Is the limit. The pores are also impregnated with a thermosetting resin or a metal having a relatively low melting point, but these impregnated substances are subject to expansion, decomposition, melting, leaching, etc. under high temperature and high pressure conditions. woken up. As a result, when the resin is impregnated, the heat resistance temperature becomes 200 ° C. or less due to the deterioration and decomposition of the resin, and the difference in the coefficient of thermal expansion between graphite and the resin causes the booster phenomenon (fire blistering). Phenomenon). In addition, when impregnated with a metal, only a metal having a relatively low melting point can be impregnated. Therefore, the heat resistance temperature remains unchanged at 400 to 500 ° C., while the chemical resistance and corrosion resistance are deteriorated, and the sliding characteristics are reduced.

Solid lubricant-dispersed sintered metal bearings in which graphite, molybdenum disulfide, etc. are uniformly dispersed by powder metallurgy are also used.These have improved mechanical strength compared to graphite bearings, The temperature does not exceed 400-500 ° C, and the base material is bronze or iron, so it is inferior in chemical resistance and corrosion resistance.

The temperature range in which this lead monoxide exhibits excellent lubricity over a long period is 480 to 850 ° C. In order to cover the lubricating property in the temperature range lower than that, that is, from room temperature to about 500 ° C., about 5 μm of molybdenum disulfide in the form of ultrafine particles (particle diameter of about 0.05 to 0.7 μm) is added to the pores of the sintered member. Impregnation with lubricating oil dispersed at a concentration of 〜20% is also performed.

Even if the surface of molybdenum disulfide is oxidized, it exhibits a low coefficient of friction as long as unoxide remains inside, so impregnation with lubricating oil in which molybdenum disulfide is dispersed is effective for maintaining sliding characteristics. is there. As the lubricating oil, general mineral oil or synthetic lubricating oil is used. In addition, such
At operating temperatures below 500 ° C., metallic lead can be used instead of lead oxide.

なるので好ましくない。[0013] The addition of 2 to 10% by weight of graphite in addition to cobalt and lead oxide is effective for improving the sliding characteristics in the operating temperature range of about 100 to 450 ° C, especially the coefficient of friction. Although the oxidation of graphite progresses from about 400 to 500 ° C, it is uniformly dispersed and maintained in the stainless steel base material, so the oxidation rate is slow and the graphite inside the base material gradually slides due to sliding. Appears on the moving surface and continuously exerts lubricity. Such an effect becomes more remarkable when the amount of graphite is gradually increased from 2% by weight. However, adding more than 10% by weight is not preferable because the strength of the stainless steel base material is reduced and the material becomes brittle.

It is preferably performed at a pressure of about 4 to 6 ton / cm 2 . That is, when it is desired to increase the impregnation amount of the molybdenum disulfide-dispersed lubricating oil, molding is performed at a low pressure, and when it is desired to decrease the impregnation amount, molding is performed at a high pressure.

顕著に現われる。From the above results, the following can be said. (1) At room temperature, the effect of impregnating the molybdenum disulfide-dispersed lubricating oil is very large. The quantity and the coefficient of friction are greatly reduced. In addition, the impregnated bearing of Example 1 is significantly superior to the graphite bearing of Comparative Example 1 in each performance. (2) At 450 ° C, the impregnated lubricating oil scatters and partially oxidizes and carbonizes. However, the molybdenum disulfide impregnated in the pores remains as it is, providing lubricity, and at the same time, lead monoxide starts to exhibit a lubricating effect. This is because, for each material, those impregnated with molybdenum disulfide-dispersed lubricating oil have better performance than non-impregnated lubricating oil, and the performance containing lead monoxide is particularly better than other materials. It is supported from the fact. On the other hand, in the case of the graphite bearing of Comparative Example 1, in the atmosphere at 450 ° C., oxidation proceeds to the inside in a short time, and a reaction occurs such that CO 2 is generated and graphite is scattered. Of the inner diameter of the bearing becomes extremely large, and each performance becomes inferior to that of the bearing of the embodiment. (3) At 700 ° C., the graphite scatters more from the graphite bearing, exposing the stainless steel mesh, further increasing the inner diameter wear amount, and at the same time, increasing the friction coefficient due to the effect of the mesh. Even in this state, since the graphite remains, the friction coefficient is smaller than that of the stainless steel base material alone, but the stainless steel mesh cannot withstand the load and the bearing inner diameter is greatly deformed. On the other hand, in the impregnated bearing of Example 1, lead monoxide exerts a lubricating effect, and molybdenum disulfide MoS 2 changes to MoO 3 , but the lubricating effect remains, and the surface of MoS 2 is oxidized. However, as long as MoS 2 remains inside, a low friction coefficient is exhibited, so that the performance difference from the graphite bearing becomes more remarkable.
