Abstract
Description
図1は、本発明に係るロータリ圧縮機の実施例を示す縦断面図である。図2は、実施例のロータリ圧縮機の圧縮部を示す横断面図である。
次に、図3〜図8を参照して実施例のロータリ圧縮機1の特徴的な構成について説明する。図3は、実施例のロータリ圧縮機1のステータ111とロータ112の組立前を示す縦断面図である。図4は、実施例のロータリ圧縮機1のステータ111とロータ112の組立後を示す縦断面図である。図5は、実施例のロータリ圧縮機1の圧縮部12及びステータ111と圧縮機筐体10の胴部10Aの嵌合前の状態を示す縦断面図である。図6は、実施例のロータリ圧縮機1の圧縮部12及びステータ111と圧縮機筐体10の胴部10Aの嵌合後の状態を示す縦断面図である。図7は、実施例のロータリ圧縮機1のステータ111の要部を示す斜視図である。図8は、実施例のロータリ圧縮機1の圧縮機筐体10とステータ111とのアーク溶接部を図1のA−A線に沿って示す横断面図である。
次に、図8〜図11を参照して、圧縮機筐体10の胴部10Aに対する圧縮部12の上端板160T及びモータ11のステータ111の接合状態を説明する。図9は、実施例のロータリ圧縮機1の圧縮機筐体10とステータ111との溶接前の状態を拡大して示す横断面図である。図10は、実施例のロータリ圧縮機1の圧縮機筐体10とステータ111との溶接後の状態を拡大して示す横断面図である。図11は、実施例のロータリ圧縮機1の圧縮機筐体10とステータ111とのアーク溶接部の位置を示す側面図である。
上述したように、実施例のロータリ圧縮機1におけるステータ111の外周部は、凹部164を有すると共に圧縮機筐体10の胴部10Aの内周部に中間ばめ状態で固定される。圧縮機筐体10の胴部10Aは、ステータ111の凹部164と接合されたアーク溶接部163Bを有する。これにより、圧縮機筐体10の外周部に貫通穴や止まり穴を加工する場合と比べて、圧縮機筐体10とステータ111とのアーク溶接部163Bの溶接状態の信頼性を高めることができる。
