Se conocen numerosos sistemas y medios para realizar la articulación o giro relativo entre dos partes o cuerpos. Ahora bien, cuando se trate de articulaciones giratorias en las que exista una solicitación de grandes esfuerzos, las soluciones son complejas y de elevado costo. Numerous systems and means are known to perform the relative articulation or rotation between two parts or bodies. However, in the case of rotating joints in which there is a great effort, the solutions are complex and expensive.
Por parte del inventor se desconoce si existen o no dispositivos de articulación giratoria con las características de la invención. DF.SCRTPCT N fíF T A TNVFNrTÓN It is unknown to the inventor whether or not rotating articulation devices exist with the characteristics of the invention. DF.SCRTPCT N FÍF TA TNVFNrTÓN
El dispositivo de articulación giratoria comprende un cilindro rotatorio sobre el que van fijados dos conjuntos de rodamientos y éstos vinculados a sendos elementos de fijación a los dos cuerpos cuya articulación giratoria se pretende. Mas concretamente los elementos que han de fijarse a los cuerpos cuya articulación giratoria se pretende, están previstos para que cada cuerpo al que se fija el elemento correspondiente sea capaz de soportar los esfuerzos que dichos elementos transmitan durante el periodo de vida de utilización del sistema, de manera tal que dichos elementos pueden estar fijados a una parte externa del cuerpo, o bien fijados a una parte externa para luego fijar los dos elementos uno sobre el otro arriostrando el conjunto, o bien se pueden fijar de cualquier forma que se considere oportuno, siempre y cuando no afecte al funcionamiento del sistema. The rotary articulation device comprises a rotary cylinder on which two sets of bearings are fixed and these are connected to respective fixing elements to the two bodies whose rotational articulation is intended. More specifically, the elements to be fixed to the bodies whose rotational articulation is intended, are provided so that each body to which the corresponding element is fixed is able to withstand the stresses that said elements transmit during the lifetime of use of the system, in such a way that said elements can be fixed to an external part of the body, or fixed to an external part to then fix the two elements one on the other bracing the whole, or they can be fixed in any way that is considered appropriate, as long as it does not affect the functioning of the system.
El cilindro central sobre el que van montados los rodamientos relacionados con los dos elementos de fijación, deben ser soportados en la dirección del eje y en ambos sentidos, siendo éste además capaz de rotar, para lo que tales elementos de fijación irán fijados al propio cilindro rotatorio. The central cylinder on which the bearings related to the two fastening elements are mounted must be supported in the direction of the axis and in both directions, this being also capable of rotating, for which such fastening elements will be fixed to the cylinder itself rotary
En el dispositivo puede utilizarse cualquier tipo de rodamiento y estarán colocados para soportar fuerzas de compresión, favoreciendo la rotación del sistema. Any type of bearing can be used in the device and will be placed to support compression forces, favoring the rotation of the system.
Además, los rodamientos pueden ir dispuestos sobre un carril susceptible de ir fijado a una junta de acople, en cada caso, para guiar a los rodamientos por la trayectoria adecuada, si fuera necesario, o bien para servir como elemento de desgaste por el rozamiento consecuente de la rodadura de los rodamientos. In addition, the bearings can be arranged on a rail capable of being fixed to a coupling joint, in each case, to guide the bearings through the appropriate path, if necessary, or to serve as an element of wear by the friction consequent rolling of the bearings.
En cada junta de acople de los rodamientos se puede colocar un refuerzo para sujeción del carril a la propia junta de acople, o para permitir incluso la eliminación de dicho carril, ya que éste se utilizará especialmente cuando las juntas de acople de los rodamientos estén materializadas en fibra de vidrio o de cualquier otro material vulnerable al desgaste a la rodadura. In each bearing coupling, a reinforcement can be placed to fasten the rail to the coupling joint itself, or to allow even the removal of said rail, since this will be used especially when the coupling joints of the bearings are materialized in fiberglass or any other material vulnerable to wear and tear.
El dispositivo así descrito es aplicable en multitud de mecanismos, máquinas y dispositivos, como por ejemplo en un catamarán, en el que los brazos o elementos que unen lateralmente la estructura central del catamarán con los cascos o patines laterales están articulados, de forma tal que esos elementos de unión lateral están articulados por una parte al lateral de la estructura central y por otra parte al casco o patín lateral correspondiente, consiguiendo de esta manera un carácter plegable. The device thus described is applicable in a multitude of mechanisms, machines and devices, as for example in a catamaran, in which the arms or elements that join laterally the central structure of the catamaran with the helmets or lateral skids are articulated, in such a way that these lateral joining elements are articulated on one side to the side of the central structure and on the other hand to the corresponding side helmet or skate, thus achieving a folding character.

También se pueden arriostrar entre si los elementos (3) y (3 '), y fijarse el elemento (3 '). As can be seen in the figures referred to, the rotary articulation device between two bodies, according to the invention, comprises a rotary cylinder (1) which, through corresponding sets of bearings (2, 2 '), is related to both elements ( 3, 3 ') intended to be fixed to the corresponding bodies whose rotational articulation is intended, in such a way that the element (3) will be or will be fixed to one of the bodies, and the element (3') will be fixed to the other body, independently, relating to each other by means of the commented assembly that form the rotating cylinder (1) and the bearing assemblies (2, 2 '). The elements (3) and (3 ') can also be braced together, and the element (3') fixed.
Los conjuntos de rodamiento (2, 2') comprenden sendas juntas de acople (4, 4') para los propios rodamientos (5, 5'), de manera tal que dichas juntas de acople (4, 4') van fijadas al cilindro central y rotatorio (1), apoyándose en tales juntas (4, 4') los rodamientos (5, 5'), siendo capaz de soportar los esfuerzos que transmitan dichos rodamientos. Las juntas de acople (4, 4') contarán con los oportunos orificios (6) para la fijación, así como un refuerzo anular (7) y un hueco (8), también anular, para el correspondiente carril (9) de los rodamientos (5, 5'). The bearing assemblies (2, 2 ') comprise respective coupling joints (4, 4') for the bearings (5, 5 ') themselves, in such a way that said coupling joints (4, 4') are fixed to the cylinder central and rotary (1), resting on such joints (4, 4 ') the bearings (5, 5'), being able to withstand the stresses transmitted by said bearings. The coupling joints (4, 4 ') will have the appropriate holes (6) for the fixation, as well as an annular reinforcement (7) and a recess (8), also annular, for the corresponding rail (9) of the bearings (5, 5 ').
Los comentados orificios (6), sirven como medios de fijación entre ambos grupos de rodamientos, mediante los correspondientes elementos de unión, no representados en las figuras, de modo que al unirse los mismos se transmiten los esfuerzos entre ambos conjuntos, evitando que estos se doblen, siendo los puntos de unión mas adecuado aquellos que coinciden con la imaginaria línea circular de apoyo de los rodamientos, si bien estos elementos podrían disponerse circunferencialmente sobre la zona exterior, o bien igualmente a distintos radios sin que ello afecte a la esencia de la invención. The aforementioned holes (6) serve as fixing means between both groups of bearings, by means of the corresponding joining elements, not represented in the figures, so that when they are joined, the forces between the two assemblies are transmitted, preventing them from double, being the most suitable points of union those that coincide with the imaginary circular line of support of the bearings, although these elements could be arranged circumferentially on the outer zone, or equally to different radios without affecting the essence of the invention.
