Timon para barcosBoat rudder
La invencion se refiere a una disposicion de timon para barcos rapidos con helices muy cargadas.The invention relates to a helm arrangement for fast boats with heavily loaded propellers.
Los timones de barco, como timones suspendidos o timones perfilados compensados, con o sin orza articulada, se conocen en las mas diferentes formas de realizacion.Ship rudders, such as suspended rudders or offset profiled rudders, with or without articulated orza, are known in the most different embodiments.
El documento DE 44 26 953 A1 describe un timon o una tobera de timon con orza articulada para vehfculos acuaticos, que presenta un timon principal basculante o una tobera de timon basculante y una orza, articulada al timon principal o a la tobera de timon, en donde el timon principal o la tobera de timon esta fijado(a) a un apoyo de platillo de columnas huecas plano, dispuesto en la estructura de suelo de la popa del barco en el emplazamiento de la limera de timon conocida generalmente, y en donde en el apoyo de platillo de columnas huecas esta montado de forma giratoria un eje de timon de orza, que se lleva a union efectiva con la orza a traves de una union de palanca- pivote-pieza deslizante-horquilla.Document DE 44 26 953 A1 describes a rudder or an articulated rudder nozzle for aquatic vehicles, which has a tilting main rudder or a tilting rudder nozzle and an orza, articulated to the main rudder or rudder nozzle, where the main rudder or rudder nozzle is fixed (a) to a flat hollow column plate support, arranged in the ship's stern floor structure at the location of the generally known rudder limera, and where in the Hollow column plate support is rotatably mounted on an orza rudder shaft, which is brought into effective union with the orza through a lever-pivot-slide-fork piece joint.
El documento GB 332 082 A describe un timon de barco de los tipos de timon “compensado” o “semicompensado” (del ingles “balanced” o “semibalanced”). Las superficies laterales del timon convergen asimetricamente desde ambos lados del eje de timon para formar una arista delantera, que esta desplazada por encima del eje de tornillo hacia un lado y por debajo del citado eje hacia el otro lado, en donde la arista delantera esta dirigida, con una navegacion hacia adelante normal del barco, en contra del agua de la corriente de tornillo. Ademas de esto las superficies laterales convergen simetricamente desde ambos lados del eje de timon para formar una arista trasera, que se encuentra en el plano central del timon.Document GB 332 082 A describes a boat rudder of the "compensated" or "semi-compensated" rudder types ("balanced" or "semibalanced"). The lateral surfaces of the rudder converge asymmetrically from both sides of the rudder axis to form a leading edge, which is displaced above the screw axis to one side and below the aforementioned axis to the other side, where the leading edge is directed , with a normal forward navigation of the ship, against the water of the screw current. In addition, the lateral surfaces converge symmetrically from both sides of the rudder axis to form a rear edge, which is located in the central plane of the rudder.
Segun el documento JP 58030896 A se describe un timon, en el que mirandolo en seccion transversal el frontal del borde de ataque esta configurado en una forma de ala simetrica, en donde en el frontal terminal estan giradas una respecto a la otra la parte superior por encima del eje de helice y la parte inferior por debajo del eje de helice, de tal modo que se corresponden con vectores de flujo. Ademas de esto se describen secciones transversales de otro timon, en el que una seccion transversal esta desplazada con relacion a la otra seccion transversal en la zona del frontal de borde de ataque.According to JP 58030896 A, a rudder is described, in which, looking at it in cross-section, the leading edge of the leading edge is configured in a symmetrical wing shape, where the upper part is turned on the front end by the above the propeller axis and the lower part below the propeller axis, such that they correspond to flow vectors. In addition to this, cross sections of another rudder are described, in which a cross section is offset relative to the other cross section in the leading edge of the leading edge.
El documento DE-U-87 08 276 describe un timon, en particular un timon perfilado compensado para vehfculos acuaticos, con una orza articulada a la pala de timon y con un cojinete de limera de timon, el cual esta equipado como soporte en voladizo con un taladro longitudinal interior central para alojar el eje de timon para la pala de timon, esta configurado penetrando hasta la pala de timon unida al extremo de eje de timon, en su taladro interior presenta un cojinete para el montaje del eje de timon y, sobre su superficie de pared, presenta aproximadamente a la misma altura que el cojinete en el taladro longitudinal interior del cojinete de limera de timon otro cojinete para alojar y apoyar la pala de timon, en donde el eje de timon es guiado con su extremo situado en la pala de timon hasta la zona del centro de eje de helice o hasta por encima del centro de eje de helice.Document DE-U-87 08 276 describes a rudder, in particular a profiled rudder compensated for aquatic vehicles, with an orza articulated to the rudder blade and with a rudder limera bearing, which is equipped as a cantilever support with a central inner longitudinal bore to accommodate the rudder shaft for the rudder blade, is configured by penetrating to the rudder blade attached to the rudder shaft end, in its inner hole it has a bearing for mounting the rudder shaft and, on its wall surface, has approximately the same height as the bearing in the inner longitudinal bore of the helm limera bearing another bearing to accommodate and support the helm blade, where the helm axis is guided with its end located in the Rudder blade to the center of the propeller shaft or up to the center of the propeller shaft.
El documento KR 2001-0009112 describe un timon de barco, en el que el extremo delantero se divide a la altura del eje de helice en parte superior e inferior, y estas se torsionan mutuamente en contrasentido. En la zona adyacente de la parte superior e inferior esta prevista una pera aerodinamica de forma correspondiente a las caracterfsticas asimetricas de los complejos flujos giratorios.Document KR 2001-0009112 describes a ship's rudder, in which the front end is divided at the height of the propeller shaft in the upper and lower part, and they twist mutually against each other. In the adjacent area of the upper and lower part, an aerodynamic pear is provided corresponding to the asymmetric characteristics of the complex rotating flows.
La tarea de la invencion consiste en producir una disposicion de timon para barcos rapidos con helices muy cargadas, en la que se eviten fenomenos de erosion en el timon a causa de la cavitacion.The task of the invention is to produce a helm arrangement for fast boats with heavily loaded propellers, in which phenomena of erosion at the helm are avoided due to cavitation.
Esta tarea es resuelta, en el caso de una disposicion de timon conforme a la clase descrita al comienzo, con las caracterfsticas indicadas en la reivindicacion 1.This task is solved, in the case of a rudder arrangement according to the class described at the beginning, with the characteristics indicated in claim 1.
Segun esto la disposicion de timon para barcos rapidos presenta un timon compuesto por una pala de timon y una helice asociada al timon, dispuesta sobre un eje de helice accionable. Ademas de esto la pala de timon se compone de solamente dos segmentos de pala de timon superpuestos, cuyos frontales de borde de ataque delanteros, vueltos hacia la helice y que presentan un perfil redondeado, estan desplazados de tal manera que un frontal de borde de ataque esta desplazado hacia babor o estribor y el otro frontal de borde de ataque hacia estribor o babor, en donde las dos superficies de pared lateral de la pala de timon confluyen en un frontal terminal alejado de la helice. Asimismo la disposicion de timon presenta una orza, que esta articulada a la pala de timon en la zona del frontal terminal.According to this, the rudder arrangement for fast boats has a rudder composed of a rudder blade and a helix associated with the rudder, arranged on an axis of operable propeller. In addition, the rudder blade is composed of only two superimposed rudder blade segments, whose front leading edge, turned towards the propeller and having a rounded profile, are displaced in such a way that a leading edge leading it is shifted to port or starboard and the other leading edge of attack to starboard or port, where the two side wall surfaces of the rudder blade converge at a terminal end away from the helix. Likewise, the helm arrangement has an orza, which is articulated to the helm blade in the area of the front terminal.
La ventaja de una disposicion de timon configurada de este modo con dos perfiles de seccion transversal invertidos lateralmente consiste, por un lado, en que se impide la formacion de burbujas de vapor y, por otro lado, en que se impiden fenomenos de erosion en la disposicion de timon o en el timon, que se producen a causa de la cavitacion en barcos rapidos con helices muy cargadas. Aparte de una considerable proteccion contra cavitacion se obtiene ademas una mejora del grado de eficacia. Se consigue un importante ahorro de peso.The advantage of a rudder arrangement configured in this way with two laterally inverted cross-section profiles consists, on the one hand, in that the formation of vapor bubbles is prevented and, on the other hand, in that erosion phenomena are prevented in the provision of rudder or rudder, which occur due to cavitation in fast boats with heavily loaded propellers. Apart from considerable protection against cavitation, an improvement in the degree of efficacy is also obtained. A significant weight saving is achieved.

ellos, de tal manera que el frontal de borde de ataque del segmento de pala de timon superior esta desplazado hacia babor y el frontal de borde de ataque del segmento de pala de timon inferior hacia estribor, o bien el frontal de borde de ataque del segmento de pala de timon superior hacia estribor y el frontal de borde de ataque del segmento de pala de timon inferior hacia babor, se obtienen respectivamente dos perfiles de seccion transversal invertidos lateralmente entre ellos de los dos segmentos de pala de timon.them, in such a way that the leading edge of the upper rudder blade segment is ported and the leading edge of the lower rudder blade segment to starboard, or the leading edge of the segment's leading edge from upper rudder blade to starboard and the leading leading edge of the lower rudder blade segment to port, two cross-section profiles laterally inverted between them of the two rudder blade segments are respectively obtained.
Ademas de esto la disposicion de timon presenta un eje de timon y un cojinete de limera de timon. El cojinete de limera de timon esta configurado como soporte en voladizo con un taladro longitudinal interior central para alojar el eje de timon para la pala de timon, y esta configurado de tal forma que penetra hasta la pala de timon unida al extremo de eje de timon, en donde para apoyar el eje de timon esta dispuesto un solo cojinete en el taladro longitudinal interior del cojinete de limera de timon, que penetra con su extremo libre en un rebajo, una imbibicion, etc, en la pala de timon, en donde el eje de timon es guiado en su zona terminal con un segmento hacia fuera del cojinete de limera de timon y, con el extremo libre inferior de este segmento, esta unido de forma desmontable a la pala de timon, en donde no esta previsto ningun apoyo entre la pala de timon y el cojinete de limera de timon y en donde la union del eje de timon a la pala de timon esta situada por encima del centro del eje de helice, en donde el cojinete interior para el apoyo del eje de timon en el cojinete de limera de timon esta dispuesto en la zona terminal del cojinete de limera de timon.In addition to this, the rudder arrangement has a rudder shaft and a rudder bearing. The rudder bearing is configured as a cantilever support with a central inner longitudinal bore to accommodate the rudder shaft for the rudder blade, and is configured such that it penetrates to the rudder blade attached to the rudder shaft end , where to support the rudder shaft a single bearing is arranged in the inner longitudinal bore of the rudder bearing, which penetrates with its free end into a recess, an imbibition, etc., in the rudder blade, where the rudder shaft is guided in its terminal area with a segment out of the rudder bearing and, with the lower free end of this segment, is detachably attached to the rudder blade, where no support is provided between the rudder blade and the rudder bearing and where the rudder shaft joint to the rudder blade is located above the center of the propeller shaft, where the inner bearing for the rudder shaft support in the l bearing helm imera is arranged in the terminal area of the helm limera bearing.
La ventaja que se obtiene en una disposicion de timon configurada de este modo, en la que el eje de timon esta montado en la zona terminal del cojinete de limera de timon mediante un cojinete, en donde la union entre el eje de timon y la pala de timon esta situada por encima del centro de eje de helice, sin que a este respecto se requiera otra cojinete para la pala de timon sobre la superficie de pared exterior del cojinete de limera de timon, consiste en que, para la sustitucion del eje de timon ya no es necesario extraer el eje de timon despues de extraer la pala de timon desde el cojinete de limera de timon, ya que la union entre el eje de timon y la pala de timon esta situada por encima del centro de eje de helice. A esto hay que anadir que la pala de timon del timon puede presentar un perfil muy estilizado.The advantage obtained in a rudder arrangement configured in this way, in which the rudder shaft is mounted in the terminal area of the rudder bearing by means of a bearing, where the union between the rudder shaft and the blade The rudder is located above the center of the propeller shaft, without requiring another bearing for the rudder blade on the outer wall surface of the rudder limera bearing, it consists in that, for the replacement of the shaft of Rudder is no longer necessary to remove the rudder shaft after removing the rudder blade from the rudder bearing, as the joint between the rudder shaft and the rudder blade is located above the center of the helix shaft. To this we must add that the helm blade can present a very stylized profile.
Ademas de esto esta previsto en una disposicion de timon que el segmento de pala de timon superior presente un perfil de seccion transversal, que esta formado por una superficie de seccion transversal delantera, que se extiende desde el frontal de borde de ataque delantero hasta el frontal de borde de ataque trasero y que se ensancha conicamente hasta un grosor de perfil maximo, asf como por una superficie de seccion transversal trasera, que se conecta a la superficie de seccion transversal delantera y se estrecha conicamente hacia el frontal de borde de ataque trasero, en donde los dos segmentos de superficie de seccion transversalIn addition to this, it is provided in a rudder arrangement that the upper rudder blade segment has a cross-sectional profile, which is formed by a front cross-sectional surface, which extends from the front leading edge to the front with a leading leading edge and which conically widens to a maximum profile thickness, as well as a rear cross-sectional surface, which connects to the front cross-sectional surface and narrows conically towards the front leading edge, where the two cross-sectional surface segments
