各連結部材の軸心方向の進退勤作を対応する羽根の取付
角度変更動作に変換するリンク機構とを具備してなるも
のが開発されている。(Prior art) This type of pump includes, for example, a rotating shaft having a hollow portion in the axial center, and a rotating shaft that is housed in the hollow portion of the rotating shaft so as to be able to move forward and backward in the axial direction, and whose tip end extends from the tip end surface of the rotating shaft. an operating shaft protruding to the outside, a crosshead provided at the tip of the operating shaft and having a plurality of mounting holes on the outer periphery, and a plurality of crossheads fixed to the tip of the rotary shaft and capable of changing the mounting angle on the outer periphery. A movable vane-shaped impeller provided with a plurality of blades, a connecting member connected to each mounting hole of the crosshead, and each connecting member provided between each of these connecting members and each of the blades. A mechanism has been developed which includes a link mechanism that converts the forward and backward movement of the blade in the axial direction into a corresponding movement of changing the mounting angle of the blade.
ところが、このように複数の羽根を複数の動作力変換機
構及び連結部材を介して共通のクロスヘッドに連接した
ものでは、全部の羽根の取付角度を一定に揃えるために
、各連結部材の前記クロスヘッドに対する連着位置を羽
根車の軸心方向に各別に調整できるようにすることが必
要となる。However, in the case where a plurality of blades are connected to a common crosshead via a plurality of operating force conversion mechanisms and connecting members, in order to make the mounting angles of all the blades constant, it is necessary to adjust the cross head of each connecting member. It is necessary to be able to adjust the position of attachment to the head individually in the axial direction of the impeller.
