[0003] Dicha helice con palas orientables, tambien llamada helice con paso variable, permite especialmente una mejor maniobrabilidad que una helice convencional con palas fijas. Ademas, dicha helice con palas orientables puede ser adaptada facilmente a las especificidades de diversos vehlculos marinos.[0003] Said propeller with adjustable blades, also called variable pitch propeller, especially allows better maneuverability than a conventional propeller with fixed blades. In addition, said propeller with adjustable blades can be easily adapted to the specificities of various marine vehicles.
25 [0004] Habitualmente, los medios de desplazamiento de las palas comprenden un gato hidraulico,[0004] Usually, the means of displacement of the blades comprise a hydraulic jack,

[0032] Debe observarse que el manguito 48, que coopera con la corredera 52, y los medios de union en[0032] It should be noted that the sleeve 48, which cooperates with the slide 52, and the joining means in
rotacion 56, forman juntos medios 61 de conexion cinematica entre el rotor 44 y la corredera 52, capaces derotation 56, together form means 61 of kinematic connection between the rotor 44 and the slide 52, capable of

[0033] Ventajosamente, el motor 28 es de doble sentido de rotacion, para permitir el desplazamiento de la corredera 52 en dos sentidos opuestos paralelamente al eje longitudinal X.[0033] Advantageously, the motor 28 is double direction of rotation, to allow the sliding of the slide 52 in two directions opposite parallel to the longitudinal axis X.

[0034] Los medios de desplazamiento 26 constan finalmente de medios 62 de conexion de la corredera 52 con cada pala 24, capaces de convertir una traslacion de la corredera 52 paralelamente al eje longitudinal X en una rotacion de cada pala 24 alrededor del eje radial R correspondiente.[0034] The displacement means 26 finally consist of means 62 for connecting the slide 52 with each blade 24, capable of converting a translation of the slide 52 parallel to the longitudinal axis X into a rotation of each blade 24 about the radial axis R correspondent.
30 [0035] Los medios de conexion 62 constan, por ejemplo, de, para cada pala 24, una varilla 64, portada por la[0035] The connection means 62 consist, for example, of, for each blade 24, a rod 64, carried by the
base 24A de la pala 24, que se extiende paralelamente al eje radial R de esta pala 24, de manera descentrada con respecto a este eje radial 24, desde la base 24A en direction del eje longitudinal X.base 24A of the blade 24, which extends parallel to the radial axis R of this blade 24, off-center with respect to this radial axis 24, from the base 24A in the direction of the longitudinal axis X.
[0036] Los medios de conexion 62 constan tambien, para cada pala 24, de al menos un elemento de empuje[0036] The connection means 62 also comprise, for each blade 24, at least one thrust element.
35 66 portado por la corredera 52, por ejemplo alojado en una ranura cillndrica de la corredera 52, que coopera con la varilla 64 correspondiente. De este modo, en caso de traslacion de la corredera 52 a lo largo del eje longitudinal X, la varilla 64 es desplazada por el elemento de empuje 66. Debido a que esta descentrada, el desplazamiento de esta varilla 64 acciona la rotacion de la pala 24 alrededor del eje radial R correspondiente.35 66 carried by the slide 52, for example housed in a cylindrical groove of the slide 52, which cooperates with the corresponding rod 64. Thus, in case of translation of the slide 52 along the longitudinal axis X, the rod 64 is displaced by the pushing element 66. Because it is offset, the displacement of this rod 64 triggers the rotation of the blade 24 around the corresponding radial axis R.
40 [0037] Preferentemente, la corredera 52 consta de dos elementos de empuje 66, dispuestos a uno y otro lado[0037] Preferably, the slide 52 consists of two thrust elements 66, arranged on either side.
de la varilla 64 en la direccion del eje longitudinal X. De este modo, uno u otro de los elementos de empuje 66 desplaza a la varilla 64, en funcion del sentido de desplazamiento de la corredera 52.of the rod 64 in the direction of the longitudinal axis X. In this way, one or the other of the thrust elements 66 displaces the rod 64, depending on the direction of travel of the slide 52.
[0038] Ventajosamente, el dispositivo de propulsion 10 consta de al menos un sensor 68 de position de la 45 corredera 52, por ejemplo portado por la carcasa 30. Este sensor de posicion 68 permite conocer la posicion de la[0038] Advantageously, the propulsion device 10 consists of at least one position sensor 68 of the slide 52, for example carried by the housing 30. This position sensor 68 allows to know the position of the
corredera 52 a lo largo del eje longitudinal X, lo que permite deducir a partir de ella la posicion angular de la pala 24 alrededor del eje radial R.slide 52 along the longitudinal axis X, which allows deducing from it the angular position of the blade 24 around the radial axis R.
[0039] A continuation se describe el funcionamiento del dispositivo de propulsion 10.[0039] The operation of the propulsion device 10 is described below.

[0040] La helice, cuando sus palas 24 estan fijas con un paso determinado, presenta un funcionamiento convencional conocido por si mismo. En particular, el arbol 12 es accionado por sus medios de accionamiento convencionales, y el arbol 12 acciona en rotacion la helice 20, al igual que la varilla 64 y el elemento de empuje 66.[0040] The propeller, when its blades 24 are fixed with a certain pitch, has a conventional operation known per se. In particular, the shaft 12 is driven by its conventional drive means, and the shaft 12 rotates the propeller 20 in rotation, as does the rod 64 and the thrust element 66.
55 [0041] Durante este funcionamiento, el motor 28 esta desactivado, de modo que el rotor 44 y el manguito 4855 [0041] During this operation, the motor 28 is deactivated, so that the rotor 44 and the sleeve 48
permanecen inmoviles alrededor del eje longitudinal X. La corredera 52 permanece, por lo tanto, inmovil a lo largo del eje longitudinal X, de modo que la orientation de las palas 24 permanece fija.they remain immobile around the longitudinal axis X. The slide 52 therefore remains immobile along the longitudinal axis X, so that the orientation of the blades 24 remains fixed.
[0042] Por el contrario, cuando se desea modificar la orientacion de las palas 24, el motor 28 esta activado.[0042] On the contrary, when it is desired to modify the orientation of the blades 24, the motor 28 is activated.
El rotor 44 entra, por lo tanto, en rotacion, accionando tambien el manguito 48 en rotacion. La corredera 52 esta entonces enroscada alrededor de este manguito 48. Dado que la corredera 52 esta inmovilizada en rotacion gracias a los medios de inmovilizacion 56, este enroscado acciona un desplazamiento en traslacion de la corredera 52 paralelamente al eje longitudinal X.The rotor 44 therefore enters into rotation, also driving the sleeve 48 in rotation. The slide 52 is then wound around this sleeve 48. Since the slide 52 is immobilized in rotation thanks to the immobilization means 56, this screwed drives a displacement movement of the slide 52 parallel to the longitudinal axis X.
55
[0043] Se observara que el sentido de desplazamiento de la corredera 52 depende del sentido de rotacion del manguito 48, por lo tanto, del rotor 44.[0043] It will be noted that the direction of travel of the slide 52 depends on the direction of rotation of the sleeve 48, therefore, of the rotor 44.
[0044] Al desplazarse, la corredera 52, por medio del elemento de empuje 66, empuja la varilla 64 10 correspondiente que, debido a que esta descentrada con respecto al eje radial R, acciona la rotacion de la pala 24[0044] When moving, the slide 52, by means of the pushing element 66, pushes the corresponding rod 64 10 which, because it is offset with respect to the radial axis R, drives the rotation of the blade 24
alrededor de este eje radial R.around this radial axis R.
[0045] El sensor de posicion 68 permite conocer la orientacion de la pala 24, para desactivar el motor 28 en cuanto se obtiene la orientacion deseada.[0045] The position sensor 68 allows to know the orientation of the blade 24, to deactivate the motor 28 as soon as the desired orientation is obtained.
