25 Descripción de la invención. Description of the invention.

El dispositivo generador de un movimiento de giro objeto de esta invención, siendo de una gran sencillez constructiva, presenta unas características orientadas a permitir su funcionamiento de una forma continuada y sin necesidad de realizar un aporte externo de combustible o energía durante su funcionamiento. The device that generates a turning movement object of this invention, being of great constructive simplicity, has characteristics oriented to allow its operation in a continuous way and without the need to make an external contribution of fuel or energy during its operation.

El dispositivo generador de movimiento de giro objeto de esta invención comprende: un elemento interior, giratorio; The rotation movement generating device object of this invention comprises: an interior, rotating element;

30 un eje fijado al mencionado elemento interior y que gira solidariamente con el mismo; y un cuerpo exterior fijo, montado coaxialmente respecto al elemento interior; presentando el elemento interior y el cuerpo exterior unas superficies enfrentadas mutuamente. 30 an axis fixed to the said inner element and which rotates integral with it; and a fixed outer body, coaxially mounted with respect to the inner element; the inner element and the outer body presenting surfaces facing each other.

Para conseguir los objetivos propuestos el elemento interior y el cuerpo exterior disponen en sus superficies enfrentadas de sendas series de imanes enfrentados, dispuestos circularmente en un plano perpendicular al eje In order to achieve the proposed objectives, the inner element and the outer body have on their opposite surfaces several paths of facing magnets, arranged circularly in a plane perpendicular to the axis

35 del elemento interior, orientados con una cierta inclinación respecto a la dirección radial del eje del elemento interior y con los polos iguales enfrentados; definiendo los imanes enfrentados del elemento interior y del cuerpo exterior unos campos magnéticos antagonistas y unas fuerzas de repulsión que provocan el giro del elemento interior respecto al cuerpo exterior a medida que los imanes del elemento interior giratorio se van enfrentando con los sucesivos imanes del cuerpo exterior. 35 of the inner element, oriented with a certain inclination with respect to the radial direction of the axis of the inner element and with the equal poles facing each other; defining the opposing magnets of the inner element and the outer body antagonistic magnetic fields and repulsive forces that cause the inner element to rotate with respect to the outer body as the magnets of the rotating inner element face the successive magnets of the outer body .

40 Esta disposición inclinada de los imanes del elemento interior y del cuerpo exterior respecto a la dirección radial del eje del elemento interior permite que el elemento interior vaya girando de forma continuada debido al par de giro generado por el enfrentamiento de los campos magnéticos, de la misma polaridad, de los imanes del elemento interior y del cuerpo exterior. 40 This inclined arrangement of the magnets of the inner element and of the outer body with respect to the radial direction of the axis of the inner element allows the inner element to rotate continuously due to the torque generated by the confrontation of the magnetic fields of the same polarity, of the magnets of the inner element and the outer body.

En una realización de la invención se ha previsto que las superficies enfrentadas del elemento interior y del cuerpo exterior presenten una curvatura en dirección transversal, siendo dichas superficies del elemento interior y del cuerpo exterior curvoconvexa y curvocóncava respectivamente. In an embodiment of the invention it is provided that the facing surfaces of the inner element and the outer body have a curvature in the transverse direction, said surfaces of the inner element and the outer body being curved and curved, respectively.

Esta configuración de las superficies enfrentadas del elemento interior y del cuerpo exterior facilita el autocentrado del elemento interior respecto al cuerpo exterior durante el giro relativo de los mismos. This configuration of the facing surfaces of the inner element and of the outer body facilitates the self-centering of the inner element with respect to the outer body during their relative rotation.

Según la invención el cuerpo exterior se encuentra alojado una carcasa envolvente que presenta al menos en uno de sus laterales un orificio provisto de unos rodamientos para el apoyo del eje del elemento interior y su salida al exterior del dispositivo, de forma que el movimiento de giro proporcionado por el dispositivo pueda ser utilizado para el accionamiento de cualquier aparato o dispositivo externo. According to the invention, the outer body is housed in a casing housing that has at least one of its sides a hole provided with bearings for supporting the shaft of the inner element and its exit to the outside of the device, so that the turning movement provided by the device can be used to drive any external device or device.

En esta invención se ha previsto que los imanes del cuerpo exterior y los imanes del cuerpo interior puedan ser fijos y definir entre sí una separación constante en dirección radial; o bien que los imanes del elemento interior sean fijos y que los imanes del cuerpo exterior se encuentren montados con posibilidad de desplazamiento longitudinal en unos orificios definidos en dicho cuerpo exterior y asociados a unos medios de accionamiento que posibiliten su disposición a una distancia variable respecto a los imanes del elemento interior. In this invention it is provided that the magnets of the outer body and the magnets of the inner body can be fixed and define a constant separation in the radial direction from each other; or that the magnets of the inner element are fixed and that the magnets of the outer body are mounted with the possibility of longitudinal displacement in holes defined in said outer body and associated with actuation means that allow its arrangement at a variable distance from the magnets of the inner element.

En este segundo caso, mediante la aproximación en mayor o menor medida de los imanes del cuerpo exterior a los imanes del elemento interior se consigue que la fuerza de repulsión de sus campos magnéticos sea de una mayor o menor intensidad lo que permite variar la velocidad y el par de giro suministrado por el dispositivo. In this second case, by approximating the magnets of the outer body to the magnets of the inner element to a greater or lesser extent, it is achieved that the repulsion force of its magnetic fields is of a greater or lesser intensity which allows the speed and the torque supplied by the device.

En una realización de la invención los medios de accionamiento utilizados para provocar el desplazamiento de los imanes montados sobre el cuerpo exterior y conseguir su aproximación o alejamiento a los imanes montados sobre el elemento interior, comprenden unos empujadores para el desplazamiento de los imanes del cuerpo exterior hacia los imanes del elemento interior, y unos resortes antagonistas que tienden a desplazar dichos imanes hacia el interior de los orificios del cuerpo exterior, distanciándolos de los imanes del elemento interior. In an embodiment of the invention, the actuation means used to cause the displacement of the magnets mounted on the outer body and achieve its approach or distance to the magnets mounted on the inner element, comprise pushers for the displacement of the magnets of the outer body towards the magnets of the inner element, and antagonistic springs that tend to move said magnets into the holes of the outer body, distancing them from the magnets of the inner element.

Los mencionados empujadores, que pueden ser de accionamiento mecánico, hidráulico, neumático, o de cualquier otro tipo que se considere oportuno, son los encargados de realizar el posicionamiento efectivo de los imanes del cuerpo exterior mientras que los resortes antagonistas tienen la finalidad de mantenerlos en dichas posiciones y permitir que dichos imanes retrocedan cuando se cambia su posición mediante la actuación sobre los empujadores. The aforementioned pushers, which may be of mechanical, hydraulic, pneumatic, or any other type of action deemed appropriate, are responsible for performing the effective positioning of the magnets of the outer body while the antagonist springs are intended to keep them in said positions and allow said magnets to recede when their position is changed by acting on the pushers.

En el ejemplo de realización mostrado en las figuras 1 a 5 el dispositivo generador de movimiento de giro comprende un elemento interior (1), giratorio, un eje (2) que gira solidariamente con aquél; y un cuerpo exterior (3) montado coaxialmente con el elemento interior (1); presentando el elemento interior (1) y el cuerpo exterior (3) unas superficies enfrentadas curvoconvexa y curvocóncava respectivamente. In the exemplary embodiment shown in Figures 1 to 5, the rotational movement generating device comprises an inner element (1), rotating, an axis (2) which rotates in solidarity with it; and an outer body (3) mounted coaxially with the inner element (1); the inner element (1) and the outer body (3) presenting facing curved convex and curved surfaces respectively.

ES 2 389 791 A1 ES 2 389 791 A1

El elemento interior (1) dispone en la superficie externa, enfrentada al cuerpo exterior (3), de dos series paralelas de imanes (11, 12) enfrentados a otras dos series de imanes (31, 32) situados en la superficie enfrentada del cuerpo exterior (3). The inner element (1) has on the outer surface, facing the outer body (3), two parallel series of magnets (11, 12) facing two other series of magnets (31, 32) located on the opposite surface of the body exterior (3).

Las series de imanes (11, 31) se encuentran desfasadas angularmente respecto a las series (12, 32) tal como se puede observar claramente en la figura 2. The series of magnets (11, 31) are angularly offset with respect to the series (12, 32) as can be clearly seen in Figure 2.

En el ejemplo de realización mostrado en las figuras 1 a 5 los imanes (11, 12) y (31, 32) se mantienen en unas posiciones fijas respecto al elemento interior y al cuerpo exterior respectivamente, con sus polaridades iguales enfrentadas y con una cierta inclinación respecto a la dirección radial del eje del elemento interior (1), de forma que enfrentándose progresiva y alternativamente los imanes (11 y 31) y los imanes (12 y 32), éstos generan unas fuerzas de repulsión que provocan el giro del elemento interior (1) respecto al cuerpo exterior (3). In the exemplary embodiment shown in Figures 1 to 5, the magnets (11, 12) and (31, 32) are held in fixed positions with respect to the inner element and the outer body respectively, with their equal polarities facing each other and with a certain inclination with respect to the radial direction of the axis of the inner element (1), so that facing the magnets (11 and 31) and the magnets (12 and 32) progressively and alternately, these generate repulsion forces that cause the element to rotate inner (1) with respect to the outer body (3).

En el ejemplo mostrado el cuerpo exterior (3) se encuentra alojado una carcasa (4) que actúa de elemento de retención de los imanes (31, 32) en el interior de dicho cuerpo exterior (3). In the example shown the outer body (3) is housed a housing (4) that acts as a retaining element of the magnets (31, 32) inside said outer body (3).

En el ejemplo mostrado esta carcasa (4) está constituida por un anillo central (41) que cubre periféricamente al cuerpo exterior (3) y por unas tapas laterales (42), presentando dicha carcasa (4), lateralmente, un orificio (43) provisto de unos rodamientos (44) para el apoyo y salida al exterior del eje (2) del elemento interior (1). In the example shown this housing (4) is constituted by a central ring (41) that peripherally covers the outer body (3) and by side covers (42), said housing (4) presenting, laterally, a hole (43) provided with bearings (44) for the support and exit to the outside of the shaft (2) of the inner element (1).

Como se puede observar en las figuras 2 y 3 los imanes (11, 12) y (31, 32) presentan en su extremo anterior una curvatura análoga a la de las respectivas superficies enfrentadas, curvoconvexa y curvocóncava, del elemento interior (1) y del cuerpo exterior (3). As can be seen in Figures 2 and 3, the magnets (11, 12) and (31, 32) have at their front end a curvature analogous to that of the respective facing surfaces, curved convex and curved, of the inner element (1) and of the outer body (3).

En la variante de realización mostrado en la figura 6 los imanes (31, 32) del cuerpo exterior (3) se encuentran montados con posibilidad de desplazamiento longitudinal en respectivos orificios (34). In the variant embodiment shown in Figure 6 the magnets (31, 32) of the outer body (3) are mounted with the possibility of longitudinal displacement in respective holes (34).

En este ejemplo concreto de realización los imanes del cuerpo exterior, representados en este caso por los imanes In this specific embodiment, the magnets of the outer body, represented in this case by the magnets

(31) visibles en las secciones mostradas en las figuras 6 a 8, se encuentran montados en unos empujadores (5) que al ser accionados, por ejemplo neumáticamente por su parte posterior provocan el desplazamiento de los imanes (31, 32) hacia una posición anterior acercándolos a los imanes (11, 12) del elemento interior (1). (31) visible in the sections shown in figures 6 to 8, are mounted on pushers (5) which, when driven, for example pneumatically by their rear part, cause the magnets (31, 32) to move towards a position anterior approaching them to the magnets (11, 12) of the inner element (1).

Sobre los mencionados empujadores (5) actúan unos resortes (6) que tienden a desplazarlos hacia la zona posterior distanciando los imanes (31, 32) del cuerpo exterior de los imanes (11, 12) del elemento interior. On the aforementioned pushers (5) springs (6) act that tend to move them towards the rear area distancing the magnets (31, 32) from the outer body of the magnets (11, 12) from the inner element.

Estos resortes (6) garantizan que los imanes (31, 32) del cuerpo exterior se mantengan de forma estable en la posición determinada por los respectivos empujadores (5). These springs (6) ensure that the magnets (31, 32) of the outer body are stably maintained in the position determined by the respective pushers (5).

Mediante el accionamiento de los empujadores (5) se consigue que los imanes (31, 32) del cuerpo exterior (3) pueden desplazarse entre una posición muy próxima a los imanes (11, 12) del cuerpo (1) tal como se muestra en la figura 7, y una posición de máxima separación tal como se muestra en la figura 8. By actuating the pushers (5) it is achieved that the magnets (31, 32) of the outer body (3) can move between a position very close to the magnets (11, 12) of the body (1) as shown in Figure 7, and a position of maximum separation as shown in Figure 8.

Variando la separación de los imanes del elemento interior (1) y del cuerpo exterior, se consigue variar el par y la velocidad de giro del elemento interior (1) By varying the separation of the magnets of the inner element (1) and the outer body, it is possible to vary the torque and the rotation speed of the inner element (1)

Una vez descrita suficientemente la naturaleza de la invención, así como un ejemplo de realización preferente, se hace constar a los efectos oportunos que los materiales, forma, tamaño y disposición de los elementos descritos podrán ser modificados, siempre y cuando ello no suponga una alteración de las características esenciales de la invención que se reivindican a continuación.

The magnets of both bodies are fixed and separated by a constant separation (Reiv. 5). Alternatively, the magnets of the inner element can be fixed and those of the outer body with longitudinal displacement in holes and associated with actuating means that regulate their arrangement at a variable distance from the magnets of the inner element (Reiv. 6), where these actuation means comprise pushers that move them outwards and antagonistic springs that move them inwards (Reiv. 7). The outer body is housed in a housing constituted by a central ring and two side covers (Reiv. 8) which has at least one of its sides a hole provided with bearings for shaft support (Reiv. 4). Document D01 discloses a motor by interaction of permanent magnet magnetic fields, which comprises a central rotor (1) rotating around a main axis (2), with permanent magnets (3) distributed on its periphery; a stator formed by a plurality of rollers (5) around the central rotor (1), each rotating around a corresponding secondary axis (6) parallel to the main axis (2), with several permanent magnets (7) distributed on its periphery . The engine also includes a mechanical movement transmission to force the central rotor (1) and satellite rotors (5) to rotate in opposite directions (summary). As can be seen, document D01 anticipates the characteristics of claims 1 and 5, and from it the characteristics of claims 2,3,4 and 8 could be derived as indicated below. The use of a series of magnets or several series of magnets is considered an obvious practical embodiment for a person skilled in the art (Reiv. 2 of the application). The surface of the rotor (1) is curved, and although the surface of each of the rollers (5) would also be convex, that of the stator as a whole is curcoconcave (Reiv.3 of the application). Document D01 discloses the option of presenting the motor device with a housing (33) whose main axis (2) protrudes from both ends of the housing (33) (see from page 6, line 61 to page 7, line 10, and figure 5). The concrete shape of the housing as well as the presence of bearings in the shaft support are considered obvious design options for a person skilled in the art (Reiv. 4 and 8 of the application). The motor device disclosed in D01 also includes a control mechanism that varies the distance between the magnets by varying the distance between the main axis (2) and the secondary axes (6) on which the rollers rotate. This mechanism is based on a kinematic chain from a lever (10) that moves an adjustment wheel (19) that acts on a connecting rod

(20) and separate the secondary axes (6) (see from page 5, line 52 to page 6, line 18). The mechanism that varies the distance between the magnets that is collected in claims 6 and 7 of the application is based on springs and holes or chambers in the outer body within which the magnets move, this mechanism being much simpler than the one proposed in D01. Document D02 discloses a motor by interaction of magnetic fields in which the position of the magnets is limited within cameras, and is varied by their interaction in conjunction with springs. It is considered that one skilled in the art would attempt to combine this mechanism with document D01 to simplify the positioning mechanism with a reasonable expectation of success and thus achieve the characteristics of claims 6 and 7 of the application. Therefore, claims 1 and 5 are considered to be novel, and claims 2, 3, 4, 6, 7 and 8 lack inventive activity according to articles 6 and 8 of the Patent Law.
