Description
図3はアクチュエータとしてのベーン式オイルポンプ2に適用した例を示す。図3に示すように、オイルポンプ2は、作動室30をもつハウジング3と、作動室30に設けられ固定部品4と、固定部品4の少なくとも一部に接触しつつ作動する可動部品5とをもつ。固定部品4は、中心線Pの回りに巡らされたリング状のカム面40をもつカムリング41である。可動部品5は、カム面40に間隔を隔てて包囲され複数の溝50を外周部にもつロータ51と、ロータ51の各溝50に進退可能に嵌合され先端部がカムリング41のカム面40に摺動する複数のベーン53(材料:SKH51)とで構成されている。ロータ51は駆動源に接続されている。駆動源からの動力によりロータ51がベーン53と共に中心線Pの回りで回転すると、ベーン53の先端部はカムリング41のカム面40に沿って摺動する。この場合、ベーン53は遠心力により溝50から遠心方向(矢印A1方向)に移動して突出したり、ベーン53はカム面40に押圧されて向心方向に移動して溝50に進入したりする。この結果、隣接するベーン53で区画された室の容積が変化する。このとき、低圧の流体吸込口から流体(オイル)が作動室に吸込まれる。高圧の流体吐出口から作動室30の流体(オイル)が吐出される。カムリング41のカム面40にベーン53が摺動するため、カムリング41には一般的には強度の他に耐摩耗性が要請される。ベーン53の動作によりロータ51には一般的には強度の他に耐疲労性が要請される。
(付記項1)各請求項において、金属粉末または鉄系焼結部品が、(ニッケル量/モリブデン量)=9〜6または8〜6に設定されていることを特徴とする鉄系焼結部品、鉄系焼結部品の製造方法、アクチュエータ。この場合、ニツケル4〜3%、モリブデン0.5%が例示される。
(付記項2)鉄−ニッケル−モリブデン系の金属粉末と炭素系粉末とを混合した原料粉末で形成した圧密体を焼結した後に浸炭焼き入れして形成され、鉄−ニッケル−モリブデン−炭素系であり、密度が7.25グラム/cm3以上とされ、浸炭焼き入れされた焼き入れ組織を有することを特徴とする鉄系焼結部品。
