Abstract

L'invention concerne une combinaison de pales en forme de 米, dont les pales (9, 10, 11) s'élèvent vers le ciel couche par couche. Chaque couche de pales (9, 10, 11) est de forme rectiligne placée à 180 degrés de chaque côté d'un axe vertical central (4). La combinaison de pales des couches supérieures et inférieures est en forme de 米 en vue de dessus. Lesdites pales sont positionnées à intervalles de 45 degrés, de cette façon la vitesse de rotation de sortie peut être stabilisée. Un moteur d'entraînement (18) est monté sur une tige de protection (20) au-dessus ou en dessous des pales (9, 10, 11). Une portée de roulement (5) joignant un centre d'axe supérieur (4) et un centre d'axe inférieur (4) est dotée d'un système de circulation automatique d'huile de lubrification pour protéger les centres d'axe (4).
