Description
以下、本発明の実施形態1に係るロータリー圧縮機について詳述する。なお、ここでは空調装置に用いられる2シリンダーを有するロータリー圧縮機を例に挙げて説明する。図1は本発明の実施形態1に係るロータリー圧縮機の全体構成を示す縦断面図である。
ロータリー圧縮機では、後述するようにローラー及びベーンの摺動面積が、軸受や仕切板の摺動面積よりも小さい。そのため、ローラー及びベーンとしては、軸受や仕切板よりも硬度の高い材料が使用される。よって、ローラー及びベーンの摩耗を軽減させるため、前述の実施形態1で熱処理を施した仕切板の硬度は、ローラー及びベーンの硬度よりも低くなければならない。ローラー及びベーン>仕切板>軸受の順番に硬度が高くなるように仕切板に熱処理を施すことで、ローラー及びベーンの摩耗を軽減させることができ、かつ仕切板の摩耗も軽減させることができる。
図11のa→b→c→dは本発明の実施形態2に係るロータリー圧縮機の圧縮機構部の動作説明図であり、上下ローラー一回転中の圧縮機構部内の様子を示すものである。図11のように上下ローラー10A,11Aは、仕切板と主・副軸受の間を上下シリンダー7,8内にて偏心回転運動して摺動し、上下ベーン12A,13Aは往復運動して摺動している。
ここでは、主・副軸受5,6、仕切板9、上下ローラー10A,11A、及び上下ベーン12A,13Aの硬度を、下記の範囲に設定した。
・主・副軸受 :ロックウェルBスケール HRB65〜110(HRC0〜30相当)
・仕切板 :ロックウェルCスケール HRC30〜40
・上下ローラー:ロックウェルCスケール HRC45〜55
・上下ベーン :ロックウェルCスケール HRC55〜70
