Abstract

<B>"HéLICE MARìTIMA"<D>. A presente invenção se refere a uma hélice marítima, que apresenta pás de hélice ajustáveis (5), fixadas a um cubo de hélice (1, 2). A parte raiz (7) de cada pá de hélice (5) é montada no cubo de hélice (1, 2), para rotação em torno de um eixo que define um ângulo com a direção axial da hélice. Meios de ajuste de montagem de pás (4, 5), são adaptados para girar todas as pás (5) de uma só vez. De acordo com a invenção, os meios de ajuste de montagem de pás, compreendem um anel de ajuste de montagem de pá (4), que inclui meios de travamento (20, 21) para atuação em conjunto com meios de travamento (22, 23), sobre o cubo. O anel de ajuste (4) pode ser movido axialmente entre uma posição de travamento, na qual o anel de ajuste é bloqueado contra a rotação, e uma posição de liberação, na qual o anel de ajuste pode ser girado em relação ao cubo de hélice (1, 2). Os meios de travamento (20, 21, 22, 23) definem uma pluralidade de diferentes posições rotacionais do anel de ajuste (4). Meios de movimento de transmissão (15, 17) transferem movimento rotativo do anel de ajuste (4) para as respectivas pás (5).
