Abstract

ACOPLAMENTO DE TORQUE E MéTODO PARA REDUZIR FORçAS DE ACIONAMENTO OSCILANTES E DE LIGAçãO CINEMáTICA. Trata-se de um acoplamento de torque (13) para uma cabeça de rotor (11) de uma aeronave de asa rotativa, o qual possui chapas superior e inferior (29, 31) configuradas para rotação com um mastro do rotor (19). As ligações de acionamento (33) conectadas de forma pivotante às chapas superior e inferior (29, 31) giram ao redor de um eixo pivó geralmente paralelo e radialmente deslocado em relação a um eixo geométrico de rotação das chapas. Cada ligação (33) é engatada com ligações de acionamento adjacentes (33) para formar um anel contínuo de ligações, de modo que o movimento de uma ligação (33) em tomo de seu eixo pivó cause o movimento, na direção oposta, de cada ligação adjacente (33) em tomo de seu eixo pivó. Os elementos de acionamento (25) conectam as ligações de acionamento (33) a uma montagem configurada para receber pás de rotor. Os elementos de acionamento (25) podem ser componentes de uma junta universal, uma configuração de múltiplas barras longitudinais, uma configuração de mancal de segmentos ou de outro tipo de montagem articulada.
