Esta invención se presta adicionalmente, a una realización en la cual la carcasa en vez de ser giratoria y conectada al eje principal, es fija, estando conectada al bastidor principal mientras que dicho eje transmite su movimiento de rotación a la primera corona a la que está directamente conectado en el interior de dicha carcasa. Descripción de las figurasThis invention additionally lends itself to an embodiment in which the housing instead of being rotatable and connected to the main axis is fixed, being connected to the main frame while said axis transmits its rotational movement to the first crown to which it is directly connected inside said housing. Description of the fi gures
La figura 1 representa el conjunto del rotor y buje rígidamente conectado al eje principal. Figure 1 represents the rotor and bushing assembly rigidly connected to the main shaft.
La figura 2 muestra la variante en la que se ha eliminado el engranaje solar y el eje de salida es parte integral del porta-planetas. Figure 2 shows the variant in which the solar gear has been removed and the output shaft is an integral part of the planet carrier.
La figura 3 representa una variante sobre la figura anterior, con una transmisión de rotación específica. Descripción de la realización preferencialFigure 3 represents a variant on the previous figure, with a specific rotation transmission. Description of the preferred embodiment
Refiriéndonos a la Figura 1 el conjunto del rotor principal “R” y buje “a” está rígidamente conectado, a modo de ejemplo, por medio de una unión atornillada “y” al eje principal “b”. El otro extremo de dicho eje “b” esta conectado a la primera corona dentada “f” para rotación solidaria de ambos y estando dispuesto dicha corona dentada. Dicho conjunto gira sobre rodamientos “d” que controlan la posición y soportan las cargas impuestas sobre dicho conjunto. Dichos rodamientos están alojados en una tapa “c” que forma parte, o esta rígidamente unida, al bastidor principal “c” del aerogenerador, y por tanto provee el necesario punto fijo de reacción de la transmisión. La carcasa fija “v” envuelve exteriormente a dicha corona y está unida al bastidor fijo del aerogenerador mediante, a modo de ejemplo, una unión atornillada “t”. La segunda corona dentada “h” es fija al estar atornillada a la carcasa “v” mediante la unión atornillada “w” y dispuesta de forma que su circunferencia primitiva sea substancialmente concéntrica con la de la corona dentada “f”. La tapa posterior “i” está unida al conjunto carcasa fija-corona fija mediante la unión atornillada “w” y aloja en un alojamiento interior al rodamiento posterior del conjunto de rodamientos “l” alojado de forma substancialmente concéntrica con la circunferencia primitiva de las ruedas dentadas “f” y “h”. El engranaje solar “j” engrana con la pluralidad de planetas “p” y esta conectado, en rotación solidaria, al eje de salida “x” de la transmisión. Referring to Figure 1, the main rotor assembly "R" and bushing "a" is rigidly connected, by way of example, by means of a screwed connection "y" to the main shaft "b". The other end of said axis "b" is connected to the first gear ring "f" for integral rotation of both and said gear ring being arranged. Said assembly rotates on bearings "d" that control the position and withstand the loads imposed on said assembly. Said bearings are housed in a cover "c" that is part, or is rigidly attached, to the main frame "c" of the wind turbine, and therefore provides the necessary fixed reaction point of the transmission. The fixed housing "v" envelops said crown externally and is connected to the fixed frame of the wind turbine by means of, for example, a screwed connection "t". The second crown "h" is fixed when it is screwed to the housing "v" by means of the screwed connection "w" and arranged so that its original circumference is substantially concentric with that of the crown "f". The rear cover "i" is attached to the fixed-crown-fixed housing assembly by means of the screwed connection "w" and houses in a housing inside the rear bearing of the bearing assembly "l" housed substantially concentrically with the original circumference of the wheels jagged "f" and "h". The solar gear "j" meshes with the plurality of planets "p" and is connected, in solidarity rotation, to the output shaft "x" of the transmission.
La Figura 2 representa la variante de esta realización en la que dicho engranaje solar “j” es eliminado y el eje de salida “x” es parte integral del porta-planetas “g” siendo él el que transmite la fuerza motriz a la carga. Figure 2 represents the variant of this embodiment in which said solar gear "j" is eliminated and the output shaft "x" is an integral part of the planet carrier "g" being he who transmits the driving force to the load.
La Figura 3 representa una variante sobre la realización representada en la Figura 2 en la que el movimiento de rotación es transmitido a dicha primera corona dentada “f” por medio de una conexión flexible “fc” que como ejemplo puede ser un acoplamiento tipo Kop-flex, u otros del tipo de dientes serrados abombados. De esta forma la falta de alineamiento que pueda existir entre dicha corona dentada y dicho eje de entrada puede ser absorbida. Figure 3 represents a variant on the embodiment represented in Figure 2 in which the rotational movement is transmitted to said first toothed crown "f" by means of a flexible connection "fc" which as an example can be a Kop- type coupling. fl ex, or others of the type of bulged serrated teeth. In this way the lack of alignment that may exist between said crown gear and said input shaft can be absorbed.
