PROBLEM TO BE SOLVED: To provide a blade inclination mechanism for preferentially inclining a blade of a rotor connected to a rotating shaft.SOLUTION: A blade inclination mechanism HP1 for a blade 6 arranged at a hub 8 of a rotor is constituted in such a way that a slide boss 10i reciprocatably arranged in a rotating shaft 7 of a rotor and a blade 6 are connected through an arm 19 pivotally supported at the extremity end side of the rotating shaft 7 and connecting means 22, the slide boss 10i moved in cooperation with the blade 6 inclined to the downstream side of fluid as the flow speed of fluid received by the blade 6 is increased is held by a plurality of holding springs 10c and as the flow speed of the fluid is deceased, the slide boss 10i is returned back to the extremity end side of the rotating shaft 7 by a biasing force of the plurality of holding springs 10c and a centrifugal force acted on the blade 6 to cause the inclination of the blade 6 to be recovered.SELECTED DRAWING: Figure 1
【課題】回転軸に連結した回転体のブレードを好適に傾倒させるブレード傾倒機構を提供する。【解決手段】回転体のハブ8に設けたブレード6のブレード傾倒機構HP1は、回転体の回転軸7内に往復動可能に配設されたスライドボス10iとブレード6とを回転軸7の先端側に枢支されたアーム19および連結手段22を介して連結し、ブレード6の受ける流体の流速が大きくなって流体の下流側に傾くブレード6に連動して移動してきたスライドボス10iを複数の挟持バネ10cで挟持し、流体の流速が小さくなると複数の挟持バネ10cの付勢力およびブレード6に作用する遠心力によってスライドボス10iが回転軸7の先端側に戻されて、ブレード6の傾斜が復元するようにした。【選択図】図1
