Description

HUSILLO ARTICULABLE Y CONTINUO  ARTICULABLE AND CONTINUOUS SPINDLE
D E S C R I P C I Ó N OBJETO DE LA INVENCIÓN D E S C R I P C I O N OBJECT OF THE INVENTION
La presente invención se refiere a un husillo articulable y continuo para la transmisión de fuerzas en dispositivos mecánicos. El husillo articulable y continuo permite la creación de circuitos o configuraciones curvilíneas, e incluso cerradas o continuas para la transmisión de fuerzas. The present invention relates to an articulated and continuous spindle for the transmission of forces in mechanical devices. The articulated and continuous spindle allows the creation of curvilinear circuits or configurations, and even closed or continuous for the transmission of forces.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En el estado de la técnica son conocidos los tradicionales husillos compuestos por un eje axial provisto de una espira helicoidal, conocidos como tornillo de Arquímedes, para la transmisión de fuerzas y desplazamiento de cargas longitudinales por rotación sobre su eje axial. In the state of the art, the traditional spindles composed of an axial axis provided with a helical spiral, known as Archimedes' screw, are known for the transmission of forces and displacement of longitudinal loads by rotation on their axial axis.
Dichos husillos tan solo pueden adoptar una configuración rectilínea, por lo que su aplicación está limitada a la elevación y transmisión de fuerzas y cargas en un sentido unidireccional, lo que representa una limitación a la hora de transmitir las fuerzas del sistema en otras direcciones transversales. These spindles can only adopt a rectilinear configuration, so their application is limited to the elevation and transmission of forces and loads in a unidirectional direction, which represents a limitation when transmitting the system forces in other transverse directions.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La presente invención resuelve el problema técnico planteado, al permitir la transmisión de fuerzas en dirección transversal al eje axial del husillo, de una forma articulable y continua. Para ello, y de forma más concreta, el husillo articulable y continuo comprende una pluralidad de tramos cilindricos, los cuales comprenden al menos una espira metálica sobre su superficie y unos medios de articulación en los extremos de los tramos consecutivos que permiten una inclinación entre los tramos comprendida entre 1o y 89° The present invention solves the technical problem posed, by allowing the transmission of forces in a transverse direction to the axial axis of the spindle, in an articulated and continuous way. To do this, and more specifically, the articulated and continuous spindle comprises a plurality of cylindrical sections, which comprise at least one metal loop on its surface and articulation means at the ends of the consecutive sections which allow an inclination between the sections comprised between 1 and 89 ° or
Los medios de articulación comprenden una orejeta en un extremo del tramo y una hendidura geométrica y dimensionalmente coincidente con la orejeta en el extremo contrario. Están provistos de un orificio pasante en correspondencia, para la inserción de un pasador de retención. El extremo provisto de la hendidura está dotado de un plano achaflanado con una inclinación comprendida entre 1o y 85°. El eje axial del orificio de la orejeta y el del orificio pasante coinciden con el punto de inicio o final de la espira metálica en los extremos del tramo cilindrico. Esto es así para que se produzca una continuidad en la espiral de las espiras de ambos tramos cilindricos cuanto éstos están alineados axialmente. El extremo del tramo cilindrico comprende un tornillo para el bloqueo del pasador de retención. The articulation means comprise an lug at one end of the section and a geometric groove and dimensionally coincident with the lug at the opposite end. They are provided with a through hole in correspondence, for the insertion of a retention pin. The end provided with the slit is provided with a chamfer at an angle between 1 and 85 ° or flat. The axial axis of the hole of the lug and that of the through hole coincide with the start or end point of the metal loop at the ends of the cylindrical section. This is so that there is continuity in the spiral of the turns of both cylindrical sections when they are axially aligned. The end of the cylindrical section comprises a screw for locking the retention pin.
Las espiras metálicas tienen una inclinación, respecto al eje axial del tramo cilindrico, comprendida entre 5o y 85°. The metal coils have an inclination, relative to the axis of the cylindrical section, or between 5 and 85 °.
Gracias a la configuración del husillo articulable y continuo de la presente invención, los tramos cilindricos se pueden encadenar de forma continua y cerrar sobre sí mismos para formar una cadena.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
Seguidamente se presenta, con ayuda de las figuras 1 a 5 anteriormente referidas, una descripción en detalle de una realización preferente de la invención. A detailed description of a preferred embodiment of the invention is presented below with the aid of Figures 1 to 5 above.
Tal y como puede apreciarse en la figura 1 , el husillo articulable y continuo (1 ) comprende una pluralidad de tramos cilindricos (2) provistos en su superficie, en el presente ejemplo de realización, de dos vueltas de espira metálica helicoidal (3), cuyo tramo cilindrico (2) tiene una longitud de 12 cm y un diámetro de 3 cm. Sus parámetros vienen dados por la inclinación de la espira (3) de 45° y por el paso o avance lineal, en este caso de 6 cm. As can be seen in Figure 1, the articulated and continuous spindle (1) comprises a plurality of cylindrical sections (2) provided on its surface, in the present embodiment, of two turns of helical metal spiral (3), whose cylindrical section (2) has a length of 12 cm and a diameter of 3 cm. Its parameters are given by the inclination of the turn (3) of 45 ° and by the step or linear advance, in this case of 6 cm.
Los extremos de cada tramo cilindrico (2) comprenden unos medios de articulación para encadenar varios tramos de forma continua. Están compuestos por, en el extremo macho, una orejeta (4) provista de un orificio pasante (5), y en el extremo hembra, una hendidura (6) geométricamente y dimensionalmente coincidente con la orejeta (4) para su acoplamiento articulable de los tramos cilindricos (2). El extremo hembra del tramo cilindrico (2), dispone de un orificio pasante (7) en correspondencia con el orificio pasante (5) de la orejeta (4), para la inserción de un pasador de retención (8). Los extremos hembra de los tramos cilindricos (2) están provistos de un plano achaflanado (9) que permite y limita la inclinación entre tramos cilindricos (2) consecutivos. En el presente ejemplo de realización, la inclinación de dicho plano achaflanado (9), es de 45°, lo que permite conectar una polea dentada (13) con sus muescas (14) para las espiras (3) en su máxima posición de inclinación de la cadena. The ends of each cylindrical section (2) comprise articulation means for chaining several sections continuously. They are composed of, at the male end, a lug (4) provided with a through hole (5), and at the female end, a groove (6) geometrically and dimensionally coinciding with the lug (4) for its articulable coupling of the cylindrical sections (2). The female end of the cylindrical section (2), has a through hole (7) in correspondence with the through hole (5) of the lug (4), for the insertion of a retaining pin (8). The female ends of the cylindrical sections (2) are provided with a chamfered plane (9) that allows and limits the inclination between consecutive cylindrical sections (2). In the present exemplary embodiment, the inclination of said chamfered plane (9) is 45 °, which allows to connect a toothed pulley (13) with its notches (14) for the turns (3) in its maximum inclination position of the chain.
La fijación del pasador (8), que será el elementos de unión, de los tramos cilindricos (2), se realiza mediante un tornillo (12) dispuesto sobre el extremo hembra del tramo cilindrico (2). Su extremo interior incide sobre el pasador (8) para inmovilizarlo en dicha posición de trabajo. The fixing of the pin (8), which will be the connecting elements, of the cylindrical sections (2), is carried out by means of a screw (12) arranged on the female end of the cylindrical section (2). Its inner end affects the pin (8) to immobilize it in said working position.
Para que se produzca una continuidad en la espira helicoidal (3), cuando los tramos cilindricos (2) están alineados en una disposición rectilínea, el eje axial del orificio pasante (5) de la orejeta (4) coincide con el punto de inicio (10) de la espira metálica (2). Y el eje axial de los orificios pasantes (7) de la hendidura (6) coincide con el punto final (1 1 ) de la espira metálica (2), tal y como puede apreciarse en la figura 1 . Para un mejor rendimiento en la transmisión de las fuerzas, las espiras metálicas (3) tienen una inclinación, respecto del eje axial del tramo cilindrico (2), de 45°. La inclinación de las espiras (3) afecta directamente a la rotación y fuerzas transmitidas: a mayor ángulo de inclinación, menores revoluciones con mayor fuerza, y a menor ángulo de inclinación, mayores revoluciones con menor fuerza. En el presente ejemplo de realización, la inclinación de las espiras metálicas de 45° da un equilibrio óptimo entre revoluciones y fuerza transmitida. For continuity to occur in the helical spiral (3), when the cylindrical sections (2) are aligned in a rectilinear arrangement, the axial axis of the through hole (5) of the lug (4) coincides with the starting point ( 10) of the metal loop (2). And the axial axis of the through holes (7) of the groove (6) coincides with the end point (1 1) of the metal loop (2), as can be seen in Figure 1. For better performance in the transmission of forces, the metal turns (3) have an inclination, with respect to the axial axis of the cylindrical section (2), of 45 °. The inclination of the turns (3) directly affects the rotation and transmitted forces: at a greater angle of inclination, lower revolutions with greater force, and at a lower angle of inclination, greater revolutions with less force. In the present embodiment, the inclination of the 45 ° metal turns gives an optimum balance between revolutions and transmitted force.
En la figura 5 puede apreciarse un husillo articulable y continuo (1 ), en la que se han encadenado una pluralidad de tramos cilindricos (2) en una configuración de rectángulo redondeado, donde los extremos curvos se han configurado mediante la articulación de 4 tramos cilindricos (2) respectivamente. Con esta configuración, el husillo articulable y continuo (1 ) puede deslizarse de forma continua, asistida por dos poleas dentadas (13) en sus extremos, de contorno poligonal acorde con la longitud de los tramos cilindricos (2) y provistas de unas muescas (14) para el engrane de las espiras metálicas (3). De este modo, el husillo articulable y continuo puede girar indefinidamente sobre las poleas dentadas (13) y transmitir o recibir una fuerza a través de los ejes axiales (15) de las poleas dentadas (13). Figure 5 shows an articulated and continuous spindle (1), in which a plurality of cylindrical sections (2) have been chained in a rounded rectangle configuration, where the curved ends have been configured by means of the articulation of 4 cylindrical sections (2) respectively. With this configuration, the articulated and continuous spindle (1) can slide continuously, assisted by two toothed pulleys (13) at its ends, of polygonal contour according to the length of the cylindrical sections (2) and provided with notches ( 14) for the gearing of the metal turns (3). In this way, the articulated and continuous spindle can rotate indefinitely on the toothed pulleys (13) and transmit or receive a force through the axial axes (15) of the toothed pulleys (13).
Las fuerzas transmitidas al husillo articulable y continuo (1 ) pueden ser trasladas a un mecanismo de engranajes, compuesto por una rueda dentada (16) y un piñón (17) para variar la relación de la transmisión de fuerzas y obtener una fuerza de giro sobre el eje de rotación axial del piñón (17), perpendicular al eje de giro (15) de las poleas dentadas (13). The forces transmitted to the articulated and continuous spindle (1) can be transferred to a gear mechanism, consisting of a gearwheel (16) and a pinion (17) to vary the ratio of the force transmission and obtain a turning force on the axial axis of rotation of the pinion (17), perpendicular to the axis of rotation (15) of the toothed pulleys (13).
