Description
一軸偏心ねじポンプ10は、いわゆる回転容積型のポンプである。一軸偏心ねじポンプ10は、図1に示すように、ケーシング12の内部にステータ20や、ロータ30、動力伝達機構部50などが収容され、ケーシング12の外部に取り付けられた駆動機70(駆動機)から伝達される動力により作動可能とされている。すなわち、一軸偏心ねじポンプ10は、ケーシング12側の部分が駆動機70から動力を受けて作動する受動機11を構成するものであり、駆動機70と受動機11とが軸方向(アキシャル方向)に軸連結された構成とされている。
続いて、一軸偏心ねじポンプ10の特徴的部分である軸連結構造体80及びこれに用いられている緩衝部材82について詳細に説明する。図3や図4に示すように、軸連結構造体80は、上述したドライブシャフト56と出力軸70aとを緩衝部材82を介して軸方向に連結することにより構成されるものである。
