Abstract

Un propulsor marino que incluye un cubo (1, 2) que define una dirección axial del propulsor, una pluralidad de palas ajustables (5) de propulsor dispuestas alrededor del cubo, y medios (4, 15) de ajuste de posicionamiento de pala, en el que cada pala (5) incluye una parte de pala y una parte (7) de raíz que está montada en el cubo y que es giratoria alrededor de un eje que define un ángulo con la dirección axial del propulsor, en el que los medios (4, 15) de ajuste de posicionamiento de pala están dispuestos para girar todas las palas (5) al unísono e incluyen un anillo (4) de ajuste de posicionamiento de pala que incluye unos primeros medios (20, 21) de inmovilización que actúan conjuntamente con unos segundos medios complementarios (22, 23) de inmovilización dispuestos sobre el cubo, en el que el anillo (4) de ajustador se puede mover axialmente entre una primera posición axial en la que dichos medios de inmovilización primeros (20, 21) y segundos (22, 23) están en aplicación mutua de inmovilización y una segunda posición axial en la que dichos medios primeros y segundos de inmovilización están fuera de aplicación entre sí y en la que el anillo (4) de ajustador es giratorio con relación al cubo (1, 2), en el que dichos primeros medios (20, 21) de inmovilización y dichos segundos medios (22, 23) de inmovilización definen juntos un cierto número de distintas posiciones rotativas del anillo (4) de ajustador con relación al cubo (1, 2), y en el que el anillo (4) de ajustador de posicionamiento de pala está conectado a cada pala (5) de propulsor por medio de medios (15) de transmisión de movimiento para ajustar la posición rotativa de cada pala (5) incrementalmente con relación a la posición rotativa del anillo (4) de ajustador, caracterizado porque los medios (15, 17) de transmisión de movimiento incluyen una pluralidad de brazos (15) de ajuste que se extienden de manera esencialmente axial, en el que un extremo de cada brazo (15) está conectado de manera no giratoria a la parte (7) de raíz de una pala y el otro extremo (16) está conectado al anillo (4) de ajustador, y en el que dicho otro extremo (16) está adaptado para acompañar el anillo (4) de ajustador a medida que se gira.
