Abstract

LA PRESENTE INVENCION PROPORCIONA UN ACCIONADOR LINEAL QUE COMPRENDE UN ARBOL DE SALIDA (4) QUE TIENE UN PAR DE RUEDAS ARRASTRADAS (6, 8), DE FORMA QUE UNA (8) PUEDE GIRAR SOBRE EL MISMO EN UNA PLANO FIJO Y TIENE UNA TUERCA DE ARRASTRE (9) PARA UNA PASO DE TORNILLO ASOCIADO (11) SOBRE DICHO ARBOL DE SALIDA, Y LA OTRA (9) QUEDA FIJA GIRATORIAMENTE (6A) EN DICHO ARBOL DE SALIDA; UN ARBOL DE ENTRADA (2) A LO LARGO DEL ARBOL DE SALIDA QUE ES GIRADO POR UNA FUENTE DE ENERGIA APROPIADA (3); Y UNA RUEDA DE ARRASTRE (5, 7) PARA CADA RUEDA ARRASTRADA FIJADA GIRATORIAMENTE EN DICHO ARBOL DE ENTRADA, DE FORMA QUE LA RAZON ENTRE CADA RUEDA DE ARRASTRE Y ARRASTRADA ES ELEGIDA PARA GIRAR LAS RUEDAS ARRASTRADAS A VELOCIDADES DIFERENTES EN LA MISMA DIRECCION DE ROTACION PARA PRODUCIR UN MOVIMIENTO AXIAL DEL ARBOL DE SALIDA QUE UNA DIRECCION QUE DEPENDE DE LA ROTACION RELATIVA DE LAS RUEDAS ARRASTRADAS. SEGUN LA INVENCION, LA RUEDA ARRASTRADA FIJA (6) Y LA RUEDA DE ARRASTRE (5) SON RUEDAS DE UN ENGRANAJE HELICOIDAL DE TRANSMISION, Y SE PROPORCIONA UN MONTAJE DE SIN AVERIAS QUE COMPRENDE UN EMBRAGUE (27, 29) ENTRE LAS RUEDAS DE ARRASTRE (5, 7) DEL ARBOL DE ENTRADA, UN ARRASTRE TRASERO (9, 11) PARA EL ARBOL DE SALIDA, Y UNOS MEDIOS DE DESVIACION (22) PARA LLEVAR A CABO EL ARRASTRE HACIA ATRAS. CUANDO ESTAN FUNCIONANDO, LOS ENGRANAJES HELICOIDALES DE TRANSMISION IMPARTEN UNA FUERZA AXIAL PARA ENGRANAR EL EMBRAGUE SOLO MIENTRAS SE SUMINISTRE ENERGIA, DE FORMA QUE LOS MEDIOS DE DESVIACION SON OPERATIVOS PARA TRANSMITIR HACIA ATRAS EL ARBOL DE SALIDA HASTA UNA POSICION SIN AVERIAS CUANDO SE ACABA EL SUMINISTRO DE ENERGIA. EL ACCIONADOR PUEDE SER MODIFICADO CON PRECISION PARA SER PUESTO EN MARCHA POR UN VEHICULO DE FUNCIONAMIENTO A DISTANCIA (VFD) EN LAS APLICACIONES SUBMARINAS.
