Abstract

Waterproof coupling for the transmission of rotation. The present invention relates to a mechanism designed to transmit a rotation movement through a hermetic wall without losing the tightness of the system. A mechanism containing an inclined axis (9) with respect to the axis of rotation (a1) is described. The inclined axis (9) rotates around the axis of rotation (a1) generating a cone whose vertex is at the intersection between the inclined axis (9) and the axis of rotation (a1). Said axis (9) transmits the rotation of its ends to two elements (6) and (12) fixed to the drive shaft (7) and the driven shaft (1) respectively by means of sliding joints (2) and (8) (such as bearings). Of friction or some type of bearing). An elastic element (11) (such as an elastic membrane or a bellows) covers part of the shaft (9) and part of the wall (5) in which the apex of the cone is located. In this way, a coupling is constituted that allows to transmit rotation and torque without having relative rotation between the oblique axis and the elastic element, so that the tightness can be guaranteed by a sufficiently firm connection.

Estado de la técnicaState of the art

En la actualidad existen distintos sistemas que permiten transmitir un movimiento de rotación entre dos regiones separadas herméticamente. Dichos sistemas se emplean generalmente cuando se necesita transmitir el movimiento a un medio fluido cuya presión es mayor que la presión del medio en el que se generó el movimiento de rotación. Esto ocurre, por ejemplo, en el medio subacuático.There are currently different systems that allow to transmit a rotation movement between two regions hermetically separated. Such systems are generally used when it is necessary to transmit the movement to a fluid medium whose pressure is greater than the pressure of the medium in which the rotatory motion. This happens, for example, in the middle underwater

Se conocen dispositivos estancos, empleados para la transmisión de rotación, basados en el uso de retenes entorno al árbol de transmisión o en el empleo del acoplamiento magnético, como, por ejemplo, el descrito en la patente JP62137297.Watertight devices are known, used to rotation transmission, based on the use of seals around the drive shaft or using magnetic coupling, as, for example, the one described in JP62137297.

Por otra parte, la eficiencia de estos dispositivos depende de la aplicación y el tamaño del mecanismo. En el caso del uso de retenes, la presión de apriete necesaria será proporcional a la presión hidrostática por lo que, al aumentar la profundidad de trabajo disminuirá el rendimiento del dispositivo. Por lo tanto, este sistema es eficaz en aplicaciones náuticas en las que la transmisión de rotación se efectúa a poca profundidad y donde la energía disponible es suficiente como para compensar las pérdidas de rendimiento.Moreover, the efficiency of these devices depends on the application and the size of the mechanism. In In the case of the use of seals, the necessary tightening pressure will be proportional to the hydrostatic pressure so, by increasing the Working depth will decrease device performance. Therefore, this system is effective in nautical applications in which the rotation transmission takes place at a shallow depth and where the available energy is sufficient to compensate for performance losses

Por otro lado, el empleo del acoplamiento magnético es efectivo con respecto a la estanqueidad, al no ser necesario un contacto material entre el motor y el eje (véase patente JP62137297). Sin embargo, el sistema requiere que la separación entre imanes sea pequeña ya que, al aumentar la separación se requerirá una mayor intensidad de campo magnético para poder mantener el par de fuerza; resultando estos dispositivos poco efectivos en la transmisión de pares relativamente altos cuando la profundidad de trabajo aumenta, pues se deben aumentar los espesores de la cámara. Por otra parte, para la selección de un sistema de estanqueidad influirán los datos relativos a presión, temperatura y velocidad de rotación.On the other hand, the use of the coupling Magnetic is effective with respect to tightness, as it is not a material contact between the motor and the shaft is necessary (see JP62137297). However, the system requires that the separation between magnets is small since, by increasing the separation will require a greater intensity of magnetic field in order to maintain the torque; resulting these devices ineffective in the transmission of relatively high pairs when the depth of work increases, as the camera thicknesses. Moreover, for the selection of a sealing system will influence the pressure related data, temperature and speed of rotation.

El dispositivo propuesto mantiene un contacto material entre el eje motor y el conducido, sin embargo, no existen en el mecanismo superficies en contacto deslizante que deban mantener la estanqueidad, como las que se producen en el uso de retenes descritos anteriormente, de esta forma tendríamos mayor rendimiento y fiabilidad.The proposed device maintains a contact material between the drive shaft and the driven shaft, however, there are no in the mechanism sliding contact surfaces that must maintain tightness, such as those that occur in the use of seals described above, in this way we would have greater Performance and reliability.

Descripción de la invenciónDescription of the invention

Acoplamiento estanco para la transmisión de rotación.Tight coupling for transmission of rotation.

La presente invención se refiere a un mecanismo destinado a transmitir un movimiento de rotación a través de una pared hermética sin perder la estanqueidad del sistema.The present invention relates to a mechanism intended to transmit a rotational movement through a Hermetic wall without losing the system's tightness.

De manera más particular, la presente invención (figura 1) se refiere a un mecanismo destinado a transmitir un movimiento de rotación que contiene un eje inclinado (9) con respecto al eje de rotación (A1). El eje inclinado (9) rota entorno al eje de rotación (A1) generando un cono cuyo vértice se encuentra en la intersección entre el eje inclinado (9) y el eje de rotación (A1). Dicho eje (9) transmite la rotación de sus extremos a dos elementos (6) y (12) solidarios al eje motriz (7) y al eje conducido (1) respectivamente mediante uniones deslizantes (2) y (8) (tales como cojinetes de fricción o algún tipo de rodamiento). Un elemento elástico (11) (tal como una membrana elástica o un fuelle) cubre parte del eje (9) y parte de la pared (5) en la que se encuentra el vértice del cono. De esta forma se constituye un acoplamiento que permite transmitir rotación y par de fuerzas sin que exista rotación relativa entre eje oblicuo y el elemento elástico por lo que se puede garantizar la estanqueidad mediante una unión lo suficientemente
firme.More particularly, the present invention (Figure 1) refers to a mechanism for transmitting a rotational movement containing an inclined axis (9) with respect to the axis of rotation (A1). The inclined axis (9) rotates around the axis of rotation (A1) generating a cone whose vertex is at the intersection between the inclined axis (9) and the axis of rotation (A1). Said shaft (9) transmits the rotation of its ends to two elements (6) and (12) integral to the drive shaft (7) and the driven shaft (1) respectively by sliding joints (2) and (8) (such as bearings). friction or some type of bearing). An elastic element (11) (such as an elastic membrane or a bellows) covers part of the shaft (9) and part of the wall (5) in which the vertex of the cone is located. In this way, a coupling is constituted that allows rotation and torque to be transmitted without any relative rotation between the oblique axis and the elastic element, so that the tightness can be guaranteed by means of a sufficiently sufficient joint
firm.

De forma más detallada tenemos que la rotación inducida en el elemento inferior (6) por el eje solidario (7) es trasmitida a través del eje oblicuo (9) al elemento superior (12). En el movimiento el eje oblicuo (9) genera un cono, entorno al eje de rotación (A1), cuyo vértice pivota en el elemento deslizante (4) (tal como una rotula). Un elemento elástico (11), unido con firmeza a la cámara (5) y al eje oblicuo (9) mediante dispositivos de apriete (10) y (3), impide la entrada del fluido que ocupa el espacio exterior (II) a la cavidad estanca (I) a través de los intersticios del elemento deslizante (4). Las uniones deslizantes (2) y (8) impiden que, durante el movimiento descrito anteriormente, el eje oblicuo (9) gire entorno a su eje de simetría (A2), logrando de esta forma que el elemento elástico (11) no sufra una torsión que provoque su rotura.In more detail we have to rotate induced in the lower element (6) by the solidarity axis (7) is transmitted through the oblique axis (9) to the upper element (12). In the movement the oblique axis (9) generates a cone, around the axis of rotation (A1), whose vertex pivots in the sliding element (4) (such as a label). An elastic element (11), firmly attached to the chamber (5) and to the oblique axis (9) by means of squeeze (10) and (3), prevents the entry of the fluid that occupies the outer space (II) to the watertight cavity (I) through the interstices of the sliding element (4). Sliding joints (2) and (8) prevent that, during the described movement previously, the oblique axis (9) rotates around its axis of symmetry (A2), thus achieving that the elastic element (11) does not suffer a twist that causes its breakage.

Modos de realización de la invenciónEmbodiments of the invention

En la figura 3 se representa en perspectiva un ejemplo de realización del mecanismo descrito anteriormente. En este ejemplo un cilindro metálico (9) se hace pasar por el orificio de una rótula (4) colocada previamente en la cámara (5). Seguidamente se introducen los extremos del cilindro en dos cojinetes de fricción (2) y (8) instalados en sendos orificios oblicuos realizados en los discos metálicos (6) y (12). Una membrana de un material elastómero (11) se fija al cilindro (9) y a la cámara (5) mediante las abrazaderas (3) y (10) apretando lo suficiente como para impedir la entrada del fluido a la región estanca (I). De esta forma la rotación del eje (7) que se encuentra en el interior de la cámara (5) y que está unido al disco (6) se transmite al eje (1) que se encuentra en el exterior de la carcasa sin que el fluido que se encuentra en el exterior (II) de la cámara (5) pueda pasar al interior (I).In figure 3 a perspective view is shown exemplary embodiment of the mechanism described above. In this example a metal cylinder (9) is passed through the hole of a kneecap (4) previously placed in the chamber (5). Then the ends of the cylinder are introduced in two friction bearings (2) and (8) installed in two holes obliques made on metal discs (6) and (12). A membrane of an elastomeric material (11) is fixed to the cylinder (9) and to the chamber (5) using the clamps (3) and (10) by tightening the enough to prevent fluid from entering the region waterproof (I). In this way the rotation of the axis (7) found inside the chamber (5) and which is attached to the disc (6) it transmits to the shaft (1) that is outside the housing without the fluid found outside (II) of the chamber (5) can go inside (I).
