The device is intended to adjust the pitch of blades or propellers which are articulately coupled by means of end supports inside radial bearings which are solidly joined to a rotating head-piece of a wind generator. This adjustment may be performed either actively or passively. It is characterised in that the rotating head-piece incorporates a linear actuator (1), such as a cylinder, the shaft of which is connected to a crosspiece (14), the latter being associated with intermediate mechanisms connected to the end supports (7) of the blades (6) so as to vary the pitch thereof when the crosspiece (14) moves, being driven by the shaft of the cylinder.
L'invention concerne un dispositif destiné à régler le pas des pales ou hélices accouplées de manière articulée au moyen de supports d'extrémité, dans des bagues radiales solidaires d'une tête rotative d'un aérogénérateur. Ce réglage peut être effectué de façon active ou bien de façon passive. Le dispositif est caractérisé en ce que la tête rotative comprend un actionneur linéaire (1), tel qu'un cylindre, dont la tige est reliée à un élément en croix (14), associé à des mécanismes intermédiaires reliés aux supports d'extrémité (7) des pales (6) pour faire varier le pas de celles-ci lorsque l'élément en croix (14) est déplacé, entraîné par la tige du cylindre.
