Title (EN) MIXED FLOW TURBINE WHEEL
(FR) ROUE DE TURBINE À FLUX MIXTE
(JA) 斜流式タービンホイール
Abstract:
(EN) A mixed flow turbine wheel equipped with multiple rotor blades provided on the peripheral surface of a hub, said multiple rotor blades being configured such that when viewed in a meridian plane the front edge of each rotor blade includes a slanted edge section wherein the distance between the front edge and the axial line of a rotary shaft decreases from the tip side toward the hub side of the blade. The mixed flow turbine wheel has a flat sensor detection surface adorned with a marking that can be detected by an optical sensor device. The sensor detection surface is formed on the peripheral surface of the hub and/or the edge section of a reference rotor blade which is one of the multiple rotor blades, such that when viewed in a meridian plane the rear-edge-side angle among the two angles formed by the axial line of the rotary shaft and the normal line of the sensor detection surface is smaller than the rear-edge-side angle among the two angles formed by the axial line of the rotary shaft and the normal line of the slanted edge section.
(FR) La présente invention concerne une roue de turbine à flux mixte équipée de multiples pales de rotor disposée sur la surface périphérique d'un moyeu, lesdites multiples pales de rotor étant conçues de telle sorte que, lorsqu'elles sont visualisées dans un plan méridien, le bord avant de chaque pale de rotor comprend une section de bord oblique, la distance entre le bord avant et la ligne axiale d'un arbre rotatif diminuant du côté pointe vers le côté moyeu de la lame. La roue de turbine à flux mixte présente une surface de détection de capteur plate comprenant un marquage qui peut être détecté par un dispositif de type capteur optique. La surface de détection de capteur est formée sur la surface périphérique du moyeu et/ou la section de bord d'une pale de rotor de référence qui est l'une des multiples pales de rotor, de telle sorte que, vu dans un plan méridien, l'angle côté bord arrière parmi les deux angles formés par la ligne axiale de l'arbre rotatif et la ligne normale de la surface de détection de capteur est plus petit que l'angle côté bord arrière parmi les deux angles formés par la ligne axiale de l'arbre rotatif et la ligne normale de la section de bord incliné.
(JA) ハブの周面に設けられる複数の動翼であって、複数の動翼の各々の前縁が、子午面視において、前縁と回転軸の軸線との距離がチップ側からハブ側に向かうにつれて小さくなる斜縁部を含むように構成される複数の動翼と、を備える斜流式タービンホイールは、光センサ装置による検出が可能なマーキングが施された平坦状のセンサ検出面を有し、センサ検出面は、子午面視において、回転軸の軸線と斜縁部の法線とがなす2つの角度のうちの後縁側の角度よりも、回転軸の軸線とセンサ検出面の法線とがなす2つの角度のうちの後縁側の角度の方が小さくなるように、ハブの周面または複数の動翼のうちの一つである基準動翼の縁部、の少なくとも一方に形成される。
