Abstract

JUNTA HOMOCINÉTICA APERFEIÇOADA PARA CUBOS DE ROTOR INCLINÁVEL. Trata-se de uma junta homocinética que é configurada para uso com uma aeronave de asa rotativa contendo pelo menos um motor. Uma unidade de acionamento é acoplada a um eixo de saída do motor, a unidade de acionamento sendo capaz de girar em tomo de um eixo geométrico. Uma barra de ligação pode girar pelo menos parcialmente em relação à unidade de acionamento, em tomo de um primeiro centro de rotação, o centro de rotação estando localizado no eixo geométrico. Diversas ligações verticais acoplam a barra de ligação à unidade de acionamento, cada uma das ligações podendo ser transladada em relação à barra de ligação, à unidade de acionamento, ou a ambas. Cada ligação também pode girar em relação à barra de ligação, à unidade de acionamento, ou a ambas, em tomo de um segundo centro de rotação.
