Abstract

resumo patente de invenção: "rotor para uma turbina eólica". a presente invenção refere-se a um cubo rotativo (410) dotado de pás (420) e um meio (100) para fixar uma parte (425) das pás (420) a uma parte (415) do cubo (410). o meio de fixação (100) compreende buchas (200) dentro das quais parafusos prisioneiros (300) correspondentes podem ser fixados. pelo menos algumas das buchas (200) são providas com pelo menos uma extremidade de fixação (250) adaptada para conferir ao parafuso prisioneiro (300) um grau de rotação em relação à bucha (200). as buchas (200) podem incluir um membro de recepção interno (260) para receber uma extremidade (310) correspondente do parafuso prisioneiro (300). o membro de recepção (260) pode ser girado dentro da bucha (200) em torno de um eixo (y).
