Abstract

EL AJUSTE DEL AVANCE EN UN PROPULSOR CON LENGUETA EMPLEANDO UN ENGRANAJE PLANETARIO ENTRE UN EJE DE PIÑON (1-3) ENCHAVETADO SOBRE EL EJE DE ACCIONAMIENTO (2) Y LOS PIÑONES PLANETARIOS (5) EN LA BASE DE LAS HOJAS (4) DEL PROPULSOR QUE ESTAN MONTADAS DE FORMA GIRATORIA A TRAVES DE AGUJEROS EN EL MURO DE LA CAJA DE UN EJE (6) PUEDE REALIZARSE MANUALMENTE CON FACILIDAD REGISTRANDO LA POSICION ANGULAR RELATIVA DE UNA SEGUNDA PORCION (7) DE LA CAJA CON RESPECTO A LA PRIMERA PORCION DE LA CAJA QUE ALOJA EL ENGRANAJE PLANETARIO. EL REGISTRO DEL AVANCE TIENE LUGAR SEPARANDO DICHA SEGUNDA PORCION (7) DE LA CAJA DE DICHA PRIMERA PORCION (6) CONTRA LA RESISTENCIA DE UN RESORTE DE EMPUJE HACIA ATRAS (17) A UNA DISTANCIA SUFICIENTE PARA DESENGANCHAR UN ACOPLAMIENTO (12-13) ENTRE DICHA SEGUNDA PORCION (7) Y DICHA PRIMERA PORCION (6) DE LA CAJA, O DICHO EJE DE PIÑON (1-3), HACIENDO GIRAR DICHA SEGUNDA PORCION (7) DESENGANCHADA DE ESE MODO CON RESPECTO A LA PRIMERA PORCION (6) DE LA CAJA ANTES DE SOLTAR LATRACCION QUE PRODUCE DE NUEVO EL ENGANCHE DE LAS DOS PORCIONES EN UNA POSICION ANGULAR RELATIVA MODIFICADA. DE ESTA FORMA, LOS MEDIOS DE DETENCION PARA EL RECORRIDO DE UN SECTOR DE ARRASTRE (8) SOLIDAMENTE CONECTADOS AL EJE (1) DEL PROPULSOR, QUE ESTAN EN GRAN MEDIDA FORMADOS EN LA PARED INTERNA DE DICHA SEGUNDA PORCION DE LA CAJA, CAMBIAN SU POSICION ANGULAR RELATIVA CON RESPECTO AL SECTOR (8), MODIFICANDO ASI LA ORIENTACION DEL LIMITE ASUMIDA POR LAS HOJAS (4) CUANDO SE HACE GIRAR EL EJE DE ACCIONAMIENTO. SE EMPLEAN ELEMENTOS ELASTICOS ENTRE LAS SUPERFICIES DE APOYO PARA IMPEDIR LA DEFORMACION DE LAS MISMAS.ADJUSTMENT OF ADVANCE IN A PROPELLER WITH A TONGUE USING A PLANETARY GEAR BETWEEN A SPROCKET SHAFT (1-3) PINS ON THE DRIVE SHAFT (2) AND THE PLANETARY SPROCKETS (5) AT THE BASE OF THE PROPELLER BLADES (4) WHICH ARE ROTALLY MOUNTED THROUGH HOLES IN THE WALL OF THE BOX OF AN AXIS (6) CAN BE DONE EASILY MANUALLY RECORDING THE ANGULAR POSITION RELATIVE TO A SECOND PORTION (7) OF THE BOX WITH RESPECT TO THE FIRST PORTION OF THE BOX THAT HOUSES THE PLANETARY GEAR. THE ADVANCE RECORD TAKES PLACE BY SEPARATING THE SECOND PORTION (7) FROM THE BOX OF THE SAID FIRST PORTION (6) AGAINST THE RESISTANCE OF A REAR PUSH SPRING (17) TO A DISTANCE ENOUGH TO DISENGAGE A COUPLING (12-13) BETWEEN SAID SECOND PORTION (7) AND SAID FIRST PORTION (6) OF THE BOX, OR SAID SPROCKET SHAFT (1-3), ROTATING SUCH SECOND PORTION (7) DISENGAGED IN THAT WAY WITH RESPECT TO THE FIRST PORTION (6) OF THE BOX BEFORE RELEASING THE LATRACTION THAT PRODUCES AGAIN THE HITCH OF THE TWO PORTIONS IN A MODIFIED RELATIVE ANGLE POSITION. IN THIS WAY, THE DETENTION MEANS FOR THE TRAVEL OF A DRAG SECTOR (8) SOLELY CONNECTED TO THE AXIS (1) OF THE PROPELLER, WHICH ARE TO A LARGE EXTENT FORMED IN THE INTERNAL WALL OF SUCH SECOND PORTION OF THE BOX, CHANGE THEIR POSITION ANGULAR RELATIVE TO THE SECTOR (8), thus modifying the orientation of the limit assumed by the leaves (4) WHEN THE DRIVE SHAFT IS TURNED. ELASTIC ELEMENTS ARE USED BETWEEN THE SUPPORTING SURFACES TO PREVENT THE DEFORMATION OF THEM.
