Abstract

resumo patente de invenção: "rotor de turbina eólica". a presente invenção refere-se a rotor de turbina eólica que compreende um cubo, uma pluralidade de pás e pelo menos um sistema de passo para girar uma pá substancialmente ao longo de seu eixo longitudinal. o sistema de passo compreende um mancal, uma engrenagem e um acionamento de passo. o acionamento de passo é disposto em um flange e apresenta um motor e um pinhão que é engrenado com a engrenagem. o flange é provido com um furo e um suporte intermediário é concentricamente disposto com relação ao furo. o suporte intermediário compreende uma abertura descentralizada com relação a um eixo central do furo e o acionamento de passo é montado através da dita abertura descentralizada. a posição da abertura descentralizada é tal que o suporte intermediário pode ser disposto em uma primeira e segunda posições nas quais o pinhão de acionamento é engrenado com uma primeira e uma segunda seções da engrenagem, respectivamente.
