Abstract

USINA DE ENERGIA EóLICA E ACIONAMENTO PARA AJUSTE DE LáMINA DE ROTOR. A presente invenção refere-se a um acionamento de ajuste de lâmina de rotor para ajustar o ângulo de passo de uma lâmina de rotor de uma usina de energia eólica, compreendendo um trem de acionamento que, na extremidade de saída, pode ser conectado à lâmina do rotor e/ou um membro de suporte que sustenta a lâmina do rotor, e um acumulador de mola conectável ao trem de acionamento, o qual inclui um eixo acumulador de mola, um alojamento acumulador de mola e um meio de mola que pode ser tencionado girando-se o eixo acumulador de mola e o alojamento acumulador de mola um em relação ao outro, em que o eixo acumulador de mola e/ou o alojamento acumulador de mola podem ser desacoplados do trem de acionamento e é girado com relação ao mesmo para inclinar o acumulador de mola, em que um dispositivo de freio é provido para retardar e/ou manter o eixo acumulador de mola e/ou o alojamento acumulador de mola contra a inclinação da mola na condição desacoplada do acumulador de mola.
