旋回スクロール６のラブプロａの根元から亀裂を生じて
破損する例が少なくなＶＸ、、破損品について調査した
ところ、破面は、疲労破面を呈している。The material of the scroll member is, for example, disclosed in Japanese Patent Application Laid-Open No. 62-12
As disclosed in No. 6238-, an aluminum casting smAes sand mold, -made, iI4 product is used (see Table 1) (Table 1) [Problem to be solved by the invention] When the da is actually operated to scroll under pressure, there are few cases of VX cracking and breaking from the base of the love pro a of the orbiting scroll 6. When we investigated the damaged products, we found that the fracture surface was a fatigue fracture. showing a face.
本発明は上述の事情に謹みて為されたもので、旋回スク
ロール部材に疲労破損を生じる虞れの無いスクロール型
圧縮機を提供することを目的とする。The present invention has been devised in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a scroll compressor that is free from the risk of causing fatigue damage to the orbiting scroll member.
旋回スクロール部材のラップ根元に疲労破損な生じるの
は、核部に被圧縮流体の反力による応力が繰返して作用
するからであると判断される。It is considered that fatigue failure occurs at the base of the lap of the orbiting scroll member because stress due to the reaction force of the compressed fluid repeatedly acts on the core portion.
而して、この疲労の発生、進行を助長している原因とし
て、鋳造欠陥が考えられる。ここｒこ言う鋳造欠陥とｒ
ｉ倣況的なもので、応力渠中を生じるものを指している
。Therefore, casting defects are considered to be the cause of promoting the occurrence and progression of this fatigue. Here is the casting defect and r
It is a situational situation and refers to something that causes stress.
更に、固定スクロール部材に比して旋回スクロール部材
の破損率が縞いのｌよ、旋回動による遠心応力が繰り返
して生じる為であると考えられる。Furthermore, the reason why the failure rate of the orbiting scroll member is higher than that of the fixed scroll member is thought to be due to repeated centrifugal stress caused by the orbiting motion.
こうした判断に基づいて、旋回スクロール部材の疲労破
損を防止するＫは、−造欠陥の無い（弐面の埼１な）、
しかも強度に比して比重の小さい材料で旋回スクロール
部材を構成すれば良い。Based on these judgments, the K that prevents fatigue damage of the orbiting scroll member is - free of structural defects (Nimen no Sai 1),
Moreover, the orbiting scroll member may be made of a material having a small specific gravity compared to its strength.
そこで本発明のスクロール威圧縮機ンよ、旋回スクロー
ル部オを、アルミニウム合金Ａ：材により、熱間鍛造し
て構成する。Therefore, in the scroll compressor of the present invention, the orbiting scroll part O is constructed by hot forging aluminum alloy A material.
（１） 旋回スクロール部材をアルミニウム合金で構
成すると、強度に比して比重が小さいので、遠心応力に
よる破損防止に有効である。(1) When the orbiting scroll member is made of an aluminum alloy, its specific gravity is small compared to its strength, so it is effective in preventing damage due to centrifugal stress.
（−）上記アルミニウム合金を鋳造せずに鍛造すると鋳

どを生じる虞れが無い上に、素材に欠陥が有っても鍛造
によつて改善される。(-) If the above aluminum alloy is forged without casting, there is no risk of casting defects, especially blowholes that reduce surface smoothness, and even if there are defects in the material, they can be improved by forging. Ru.
（−）そして、鍛造を熱間で行うと、型性加工の応力が
残留しない。(-) When forging is performed hot, no stress from mold forming remains.
