Description
ともに、前記ピストンが上死点の位置にあるとき、前記主軸部軸心と前記偏心部の中心を結ぶ線の偏心部側の延長線が、前記シリンダ軸心と交差する構成とし、さらに、前記バランスウェイトの重心位置を、前記ピストンが上死点の位置にあるときにおいて、前記主軸部軸心に対して前記偏心部の中心の略反対側で、かつ前記主軸部軸心と前記偏心部の中心を結ぶ線の主軸部側の延長線と、前記主軸部軸心を含みシリンダ軸心と平行な平面Bの間の領域内に設定したもので、ピストンの側圧を低減して往復動式圧縮機の信頼性と効率を向上するとともに、ピストン、コンロッド、偏心部等の運動によるアンバランスの力を、バランスウェイトの運動による力でより効果的に打ち消して往復動式圧縮機の振動を低減することができ、信頼性、エネルギー効率が高く、かつ低振動の往復動式圧縮機を提供することができる。さらに、主軸部軸心を含みシリンダ軸心と平行な平面Bを越えない範囲設定とすることにより、容易にバランスウェイトを付加する位置を規定できるという効果が得られる。
図1は、本発明の実施の形態1による往復動式圧縮機の断面図、図2は、同実施の形態による往復動式圧縮機の上視図、図3は、同実施の形態による往復動式圧縮機の要部模式図、図4は、同実施の形態による往復動式圧縮機の振動特性図である。
03のすべり軸受構造の軸受111に回転自在に支持される。
最小となる位置(図4では真反対位置に対して+2°)へとずらすことで、最も振動を小さくすることができる。なお、この振動が最小となる位置は真反対位置からB面の位置の範囲内で実験的に求めればよい。

Claims (4)
- 密閉容器内に冷媒ガスを圧縮する圧縮要素を収容し、前記圧縮要素は、略鉛直方向に配設され、かつ主軸部および偏心部を有するクランクシャフトと、略円筒形のシリンダを形成したブロックと、前記シリンダ内を往復運動するピストンと、前記偏心部と前記ピストンを連結するコンロッドと、前記ピストン、コンロッド、偏心部等の振動をバランスさせるバランスウェイトとを備え、前記シリンダのシリンダ軸心を、前記主軸部の主軸部軸心と交わらないように前記シリンダをオフセットするとともに、前記ピストンが上死点の位置にあるとき、前記主軸部軸心と前記偏心部の中心を結ぶ線の偏心部側の延長線が、前記シリンダ軸心と交差する構成とし、さらに、前記バランスウェイトの重心位置を、前記ピストンが上死点の位置にあるときにおいて、前記主軸部軸心に対して前記偏心部の中心の略反対側で、かつ前記主軸部軸心と前記偏心部の中心を結ぶ線の主軸部側の延長線と、前記主軸部軸心を含みシリンダ軸心と平行な平面Bの間の領域内に設定した往復動式圧縮機。
- 前記ピストンが上死点の位置にあるとき、バランスウェイトの重心の位置を、前記主軸部軸心と前記偏心部の中心を結ぶ線に対し、前記主軸部の回転方向において0°〜3°の範囲内に位置するようにした請求項1に記載の往復動式圧縮機。
