Abstract

Inventia se refera la masinile de conversiune a energiei eoliene, si anume la turbinele de vant cu ax vertical de tip Darrieus. Turbina de vant cu axvertical contine un turn vertical fix (1), pe care este instalat liber un arbore rotitor de baza (2) cu niste pale (3), legate rigid cu el, fiecare pala (3) avand forma alungita elicoidala si profil aerodinamic in sectiunea perpendiculara axei longitudinale. In spatiul dintre pale (3) sunt amplasate suplimentar cel putin doua pale elicoidale (8), fixate fara spatiu de un arbore rotitor suplimentar, care este amplasat coaxial cu arborele rotitor de baza (2) si legat cu el prin intermediul unui cuplaj unisens. Arborele rotitor de baza (2) este legat rigid cu arborele generatorului electric (10). In variantele a II si a III, arborele rotitor debaza (2) si arborele rotitor suplimentar sunt legati cu arborele generatorului electric (10) prin intermediul unui diferential sinusoidal cu bile saucu roti dintate conice. Turbina de vant cu ax vertical permite conversiunea energiei eoliene in energie electrica sau mecanica cu un coeficient sporit de conversiune.
