Summary: | PROBLEM TO BE SOLVED: To provide a scroll type fluid machine having an eccentric bush capable of improving the dimensional accuracy by easy working.SOLUTION: A scroll type fluid machine comprises: a stationary scroll; a turning scroll disposed to face the stationary scroll for swirling motions; a drive shaft 6 for driving the turning scroll; an eccentric shaft 18 made eccentric from the drive shaft 6 and connected to the turning scroll; and an eccentric bush 8 for connecting the drive shaft 6 and the eccentric shaft 18. The eccentric bush 8 has a main hole, in which the drive shaft 6 is fitted, and an eccentric hole, in which the eccentric shaft 18 is fitted. The scroll type fluid machine is characterized in that the eccentric hole is made eccentric to the main hole.
【課題】容易な加工で寸法精度を向上させることができる偏心ブッシュを有するスクロール式流体機械を提供する。【解決手段】固定スクロールと、前記固定スクロールに対向して設けられ、旋回運動する旋回スクロールと、前記旋回クロールを駆動する駆動軸6と、前記駆動軸6から偏心し、旋回スクロールに接続される偏心軸18と、前記駆動軸6と前記偏心軸18とを接続する偏心ブッシュと8を備え、前記偏心ブッシュ8は、前記駆動軸6がはめ込まれる主孔と前記偏心軸18がはめ込まれる偏心孔とを有し、前記偏心孔は前記主孔に対して偏心していることを特徴とするスクロール式流体機械である。【選択図】図3 |
