Abstract

Eolienne à axe horizontal, comprenant un mât s’étendant suivant une direction verticale, une nacelle (1) pivotant autour d’un essieu de lacet (2) se développant à l’intérieur du mât, un safran (6) destiné à l’orientation de la nacelle (1), un premier moyeu (14) de rotor, entraîné en rotation par des pales autour d’un arbre dédié (13) et supportant la cellule de production d’électricité, un support (7), pincé de 45 degrés dans un sens longitudinal et incliné de 45 degrés suivant la direction verticale, pourvu de butées (8) et (9) et sur lequel est boulonné un deuxième moyeu (12), qui permet la rotation du premier moyeu (14) de rotor autour d’un axe de roulis, pour permettre un effacement vertical des pales en cas de vents forts. Selon l’invention, le deuxième moyeu (12) est monté sur un arbre de roulis (11), réuni par soudure et assemblage mécanique à l’arbre dédié (13) du premier moyeu (14), les deux arbres formant un seul essieu coudé à 135 degrés.Horizontal axis wind turbine, comprising a mast extending in a vertical direction, a nacelle (1) pivoting around a yaw axle (2) developing inside the mast, a rudder (6) intended to orientation of the nacelle (1), a first rotor hub (14), driven in rotation by blades around a dedicated shaft (13) and supporting the electricity production cell, a support (7), clamped 45 degrees in a longitudinal direction and inclined by 45 degrees in the vertical direction, provided with stops (8) and (9) and on which is bolted a second hub (12), which allows rotation of the first rotor hub (14) around a roll axis, to allow vertical vanishing of the blades in the event of strong winds. According to the invention, the second hub (12) is mounted on a roll shaft (11), joined by welding and mechanical assembly to the dedicated shaft (13) of the first hub (14), the two shafts forming a single axle angled at 135 degrees.
