Abstract
Description
そこで、本発明は、ロータのスラスト面に油膜が形成されやすくして、圧縮時の漏れ損失及び消費動力を低減することのできる技術を提供する。
上記の構成において、前記基材の回転中心に対する前記環状の溝の環の中心の偏心量または前記渦巻状の溝の渦巻の中心の偏心量が前記溝のピッチ以上であってもよい。
また、本発明は、筒状部材と、前記筒状部材の軸方向の両端の開口部を閉鎖する閉鎖部材と、上記のロータとを有するロータリー型流体機械を提供する。
以下、図において、ロータリー型圧縮機9の各構成の配置を説明するため、各構成が配置される空間をxyz右手系座標空間として表す。また、図に示す座標記号のうち、内側が白い円の中に黒い円を描いた記号は、紙面奥側から手前側に向かう矢印を表している。また、内側が白い円の中に交差する2本の線分を描いた記号は、紙面手前側から奥側に向かう矢印を表している。空間においてx軸に沿う方向をx軸方向という。また、x軸方向のうち、x成分が増加する方向を+x方向といい、x成分が減少する方向を−x方向という。y、z成分についても、上記の定義に沿ってy軸方向、+y方向、−y方向、z軸方向、+z方向、−z方向を定義する。
以上が実施形態の説明であるが、この実施形態の内容は以下のように変形し得る。また、以下の変形例を組み合わせてもよい。
2−1.適用例
上述した実施形態において、ロータリー型圧縮機9が適用される装置として、自動車用、家庭用、鉄道用、または業務用の空気調和機を挙げたが、冷凍機、冷蔵装置などに適用されてもよいし、水温調節、恒温槽、恒湿槽、塗装設備、粉体輸送装置、食品加工装置、空気分離装置など各種装置に用いられてもよい。また、上述した実施形態において、本発明に係るロータリー型流体機械の一例としてロータリー型圧縮機9を挙げたが、これ以外にも、気体を扱うロータリー型送風機や、液体を扱うロータリー型ポンプなどが本発明に係るロータリー型流体機械として挙げられる。
図6は、ロータリー型流体機械の変形例を示す図である。作動部4aは、駆動軸40a、ロータ41、ベーン42aを有する。駆動軸40aには駆動軸40a自身と異なる軸を中心とする円柱状の偏心部(図示略)が設けられており、この偏心部がロータ41a(いわゆる、ローリングピストン)の内周側にはめ込まれている。そのため、駆動軸40aが回転すると、これに伴ってロータ41aは、筒状部材1aの内周面に沿って偏心回転する。
図7は、ロータリー型流体機械の変形例を示す図である。この場合、筒状部材1bの内周面には、揺動ブッシュ45bが設けられている。作動部4bは、駆動軸40b、およびロータ41bを有する。ロータ41bは、いわゆるスイングピストンであり、板状の部材(以下、「板状部材412b」という)と円筒状の基材(以下、「円筒状基材411b」という)とを有し、板状部材412bは揺動ブッシュ45bに挟まれて気密性を保持されている。つまり、板状部材412bは、円筒状基材411bと一体に設けられ、円筒状基材411bの外周面から筒状部材の内周面に向かって延び、その内周面に設けられた揺動ブッシュ45bに挟まれる。ロータ41bと筒状部材1bの内周面との間には図7に示すような作動室5bがあり、この作動室5bは板状部材412bによって仕切られる。
図8は、溝Cの変形例を示す図である。この例において、溝Cの幅wは、溝C同士の間隔pよりも小さい(w<p)。山部Bには、溝C同士の間で幅aを有する平坦面が設けられている。この場合、幅aは幅wよりも小さい(a<w)ことが望ましい。幅aを幅wよりも小さくすることにより、作動部4と接触して弾性変形した山部Bによって溝Cが完全に埋まってしまうことがない。つまり、山部Bが溝Cに向かって弾性変形したとしても、溝Cが潤滑油80を保持するので、ロータリー型流体機械の気密性が向上する。
上述した実施形態において、駆動軸40に垂直な平面における、基材411の断面形状は円形であったが、基材411の断面形状は円形に限られない。基材411の断面形状は、例えば、楕円形であってもよいし、ルーローの多角形のような定幅図形であってもよく、また、半円と楕円を組み合わせた形状であってもよい。
上述した実施形態において、溝Cは同心円をなす環状の溝であったが、溝Cは渦巻状でもよい。この場合、溝Cの渦巻の中心がロータ41の回転中心と一致していてもくさび効果が発生するから、溝Cの渦巻の中心がロータ41の回転中心と一致していてもよい。ただし、溝Cの渦巻の中心がロータ41の回転中心と異なっている方が、全体的にくさび効果が大きくなるから、溝Cの渦巻の中心がロータ41の回転中心と異なっていることが望ましい。また、ロータ41の回転中心に対する溝Cの渦巻の中心の偏心量は、溝Cの渦巻のピッチ1つ分以上であることが望ましい(ただし、溝Cの渦巻のピッチが一定の場合)。
上述した実施形態において、樹脂層410において複数の溝Cが形成される範囲について言及していないが、樹脂層410の全面に溝Cが形成されていなくてもよく、樹脂層410の一部に溝Cが形成されていてもよい。また、2つのスラスト面に設けられた樹脂層410のうちの一方に溝Cが形成されていてもよい。
