うな斜板式コンプレッサのシューがある。A typical sliding member used under such severe conditions is the shoe of a swash plate compressor as shown in Japanese Patent Application Laid-Open No. 60-166936.

られている。Briefly explaining this swash plate type compressor, as shown in FIG. 1, a swash plate 1 includes a piston 2 moored to straddle the swash plate 1. When the swash plate 1 is rotated, the piston 2 reciprocates, and as a result, the refrigerant gas sealed inside is sucked into the cylinder bore 3 and compressed. The swash plate 1 is fixed to a shaft 5 rotatably supported by a cylinder block 4, and the piston 2 is moored to the swash plate 1 via a shoe 6 and a ball 7. When the swash plate 1 is rotated integrally by the shaft 5, the shoes 6 slide on the sliding surface of the swash plate 1 and transfer the axial movement of the outer circumference of the swash plate 1 to the piston 2 via the balls 7. It has a structure that transmits information. Such swash plate compressors are used in car coolers.

る。In the swash plate compressor used in the above car cooler, the part exposed to the most severe sliding conditions is the sliding part between the swash plate 1 and the shoe 6 shown in FIG. The sliding speed is about 2 to 3 m/sec when the engine is idling, 20 to 25 m/see at maximum rotation of about 600° rpm, and about 7 to 15 m/see even during normal running.
しかも、シューの受ける荷重は特に高回転になると衝撃

かも高速摺動するという極めて苛酷な摺動条件が斜板と
シューとの摺動部には生じる。Moreover, the load that the shoe receives becomes an impact load, especially at high rotation speeds, and the sliding conditions between the swash plate and the shoe are extremely harsh, as the shoes must be able to handle such impact loads while still sliding at high speeds. It occurs in some parts.

、含油軸受合金等が考えられていた。For this reason, swash plates are made of nickel-chromium steel, nickel-molybdenum steel, which are structural alloy steels that have mechanical rigidity, fatigue strength, and wear resistance, as materials that can withstand the high surface pressure and impact loads mentioned above. Chrome molybdenum steel, spheroidal graphite cast iron, etc. are used, and shoe materials include, in addition to the above-mentioned phosphor bronze and high-strength brass, Alsil alloy, copper-lead monotin alloy, brass, bronze, aluminum bronze, Babbitt metal, oil-impregnated bearing alloys, etc. were considered.

We have developed a sliding material that exhibits little decrease in hardness and has good sliding properties. The gist is that Cr0. l~1.0wt%, Zr0

能を改善する上で有効である。In sliding parts where the amount of lubricating oil is small, the most important issue is the thermal conductivity of the sliding members. For this reason, for shoe materials, rather than focusing on conformability, it is important to improve thermal conductivity, effectively dissipate heat, and reduce the decrease in hardness at high temperatures to minimize structural changes. It is effective in improving

に固溶できないＣｒ量が急増するため、時効後の熱伝導
度および加工性が著しく劣化するためである。The reason for setting the Cr content to be 0.1 wt% or more and 1.0 wt% or less is that if the Cr content is less than 0.1 wt%, Cr
The amount of intermetallic compounds formed between Cu precipitates and other additive elements is not sufficient, and the expected strength and heat resistance cannot be obtained.On the other hand, if the amount exceeds 1.0 wt%, Cu This is because the amount of Cr that cannot be solid-solubilized in the steel rapidly increases, resulting in a significant deterioration in thermal conductivity and workability after aging.

If the amount is less than 1.0 wt%, the amount of intermetallic compounds formed with other additive elements will not be sufficient, and the expected strength and heat resistance will not be obtained.On the other hand, if it exceeds 1.0 wt%, the Cu This is because the amount of Zr that cannot form a solid solution in the steel rapidly increases, resulting in a significant deterioration in thermal conductivity and workability after aging.
Ｓｉは、Ｃｒおよび他の添加元素との間で金属間化合物
を生成させ析出硬化を促進させるために添加させるもの
であって、Ｓｉの含有量をｏ、。Si is added to form an intermetallic compound with Cr and other additive elements to promote precipitation hardening, and the Si content is o.

０．５ｗｔ％を超えると熱伝導率の低下が著しくなるた
めである。The reason for setting the Si content to be 1 wt% or more and 0.5 wt% or less is that if the Si content is less than 0.01 wt%, the amount of intermetallic compounds generated will not be sufficient, and the expected strength and heat resistance will not be obtained.
This is because if it exceeds 0.5 wt%, the thermal conductivity will decrease significantly.

The reason for adding one or more selected from the group consisting of is that these additions have the effect of improving strength and heat resistance without significantly reducing thermal conductivity.
The reason why the total content is 0.01 wt% or more and 1.0 wt% or less is because the above-mentioned effect cannot be expected if it is less than 0.01 wt%, and if it exceeds 1.0 wt%, the thermal conductivity will decrease significantly. It is.

This is the exothermic temperature when It can be seen that even when the alloy of the present invention is slid under load, the amount of heat generated is small. FIG. 2 shows the heat generation temperature with respect to the load of typical alloy materials in Tables 1 and 2. It can be seen that the alloy of the present invention generates less heat than conventional phosphor bronze and high-strength brass.
