Description

Sistema de montaje de tuercas sobre ejes lisos.Axle nut mounting system smooth.

Sector de la técnicaTechnical sector

La presente invención está relacionada con el montaje de elementos sobre ejes de gran diámetro, con retención del montaje mediante tuercas que se deben bloquear sobre el eje para evitar el aflojamiento, proponiendo un sistema de bloqueo que permite realizar el montaje de las mencionadas tuercas de retención en condiciones muy ventajosas.The present invention is related to the assembly of elements on large diameter shafts, with retention of the mounting by nuts that must be locked on the shaft to avoid loosening, proposing a locking system that allows the assembly of the mentioned retaining nuts in very advantageous conditions.

Estado de la técnicaState of the art

Existen montajes de elementos, como por ejemplo de rodamientos sobre ejes, en donde la retención del montaje se establece mediante tuercas de retención, las cuales se deben bloquear sobre el eje de montaje para evitar el aflojamiento.There are assemblies of elements, such as of bearings on shafts, where mounting retention is established by retaining nuts, which must be lock on the mounting shaft to prevent loosening.

En ese sentido, se conocen soluciones de bloqueo de tuercas sobre el eje en el que se montan, mediante tornillos prisioneros radiales que hacen presión contra el eje, lo cual puede ocasionar el deterioro de la rosca del eje, con el consiguiente problema para el desmontaje y montaje posteriormente.In that sense, blocking solutions are known of nuts on the shaft on which they are mounted, using screws radial prisoners that press against the shaft, which can cause deterioration of the shaft thread, with the consequent problem for disassembly and assembly later.

Se han desarrollado también soluciones, como las de las Patentes U S4 086 946, GB 2 177 178 y ES 188 406, en las que la tuerca se realiza con unas ranuras axiales, incorporando tornillos radiales entrantes desde el exterior hasta dichas ranuras, de forma que mediante dichos tornillos radiales se ejerce presión sobre la pared de las ranuras situada hacia el interior de la tuerca, con lo cual la presión se transmite a través de dicha pared en contra del eje de montaje, resultando así bloqueada la tuerca sin deterioro de la rosca.Solutions have also been developed, such as of U-Patents S4 086 946, GB 2 177 178 and ES 188 406, in which The nut is made with axial grooves, incorporating radial screws entering from the outside to these slots, so that by means of said radial screws pressure is exerted on the wall of the grooves located towards the inside of the nut, whereby the pressure is transmitted through said wall against the mounting shaft, thus locking the nut without thread deterioration.

Todas esas soluciones están fundamentadas, sin embargo, en un montaje de las tuercas sobre ejes roscados, teniendo este tipo de montaje el inconveniente de que, cuando se trata de ejes de gran diámetro, la realización del roscado del eje es problemática y costosa, ya que si se realiza el roscado del eje y luego se templa, mucho del calor que se aplica se disipa por termodinámica a través de las cresta de los filetes de la rosca, con lo que esta parte queda mucho más templada que el resto del eje y, por lo tanto, resulta mucho más frágil.All these solutions are grounded, without However, in a nut assembly on threaded shafts, having this type of assembly the drawback that, when it comes to large diameter shafts, the realization of shaft threading is problematic and expensive, since if the threading of the shaft and then it is tempered, much of the heat that is applied is dissipated by thermodynamics through the crest of the thread steaks, with what this part is much warmer than the rest of the axis and, therefore, it is much more fragile.

Dicho problema hace que, para realizar un eje roscado adecuadamente, se tengan que efectuar dos etapas de torneado de la rosca, una antes de realizar el temple y otra después del temple, lo cual significa un largo y costoso, procedimiento de fabricación.This problem causes that, to make an axis Threaded properly, two turning stages must be carried out of the thread, one before tempering and another after quenching, which means a long and expensive procedure manufacturing.

Objeto de la invenciónObject of the invention

De acuerdo con la invención se propone un sistema que permite establecer con seguridad el bloqueo de tuercas sobre el eje de montaje correspondiente, utilizando ejes sin roscar, con lo que se eliminan los problemas de realización del roscado de los ejes que presentan las soluciones convencionales de montaje de tuercas con bloqueo.According to the invention, a system that allows to securely establish the nut lock on the corresponding mounting shaft, using unthreaded shafts, which eliminates the problems of making the threading of the axes that present the conventional mounting solutions of lock nuts.

Este sistema objeto de la invención comprende la utilización de una tuerca formada con una parte axial de su interior con superficie lisa y diámetro como el del eje de montaje, mientras que la parte axial restante del interior de la tuerca es de superficie roscada con un diámetro mayor que el eje de montaje, disponiéndose en relación con dicha parte roscada del interior de la tuerca un anillo de superficie exterior roscada en correspondencia con la rosca y el diámetro de esa parte interior roscada de la tuerca, en tanto que por la parte interior dicho anillo es de superficie lisa con el mismo diámetro que el eje de montaje, estableciéndose entre el eje y el anillo un enchavetado de bloqueo giratorio y un clipado de retención axial.This system object of the invention comprises the use of a nut formed with an axial part of its interior with smooth surface and diameter like that of the mounting shaft, while that the remaining axial part of the inside of the nut is of threaded surface with a diameter larger than the mounting shaft, disposing in relation to said threaded part of the interior of the nut an outer surface ring threaded in correspondence with the thread and the diameter of that threaded inner part of the nut, while on the inside said ring is of smooth surface with the same diameter as the mounting shaft, establishing a locking keyway between the shaft and the ring swivel and axial retention clipping.

En relación con la parte axial de interior liso de la tuerca, se hallan definidas en la tuerca unas ranuras axiales abiertas desde el extremo cerca de la superficie interior, hasta las cuales ranuras se hallan abiertos desde el costado unos orificios radiales roscados, en los cuales se disponen unos tornillos con los que es susceptible ejercer empuje de la pared de la otra parte de las ranuras hacia el interior.In relation to the smooth inner axial part of the nut, axial grooves are defined in the nut open from the end near the inner surface, to the which slots are open from the side holes threaded radial, in which some screws are arranged with the that it is susceptible to exert push from the wall of the other part of the grooves inwards.

Se obtiene así un sistema que permite realizar el montaje de la tuerca en acoplamiento roscado sobre el anillo dispuesto con retención giratoria y axial sobre el eje, mientras que los tornillos radiales que van incorporados en la parte de interior liso de la tuerca permiten ejercer presión de algunas partes interiores de la tuerca contra el eje, determinando con ello el bloqueo de la tuerca para evitar su aflojamiento.A system is thus obtained that allows to realize the mounting of the nut in threaded coupling on the ring arranged with rotating and axial retention on the shaft, while the radial screws that are incorporated in the interior part Smooth nut allow pressure of some parts interiors of the nut against the shaft, thereby determining the nut lock to prevent loosening.

Con este sistema la tuerca mantiene una estructura resistente en su conjunto, siendo susceptible de montaje en acoplamiento roscado como las tuercas convencionales y bloqueo en el montaje mediante tornillos de presión radiales que no inciden directamente contra el eje, como en soluciones ya conocidas, pero estableciéndose el montaje sobre un eje liso, el cual no tiene los problemas de realización constructiva que presentan los ejes roscados.With this system the nut maintains a resistant structure as a whole, being capable of mounting in threaded coupling like conventional nuts and locking in mounting by radial pressure screws that do not impact directly against the shaft, as in known solutions, but the assembly being established on a smooth axis, which does not have the construction problems presented by the axes threaded

Por todo ello, ese sistema objeto de la invención resulta de unas características ciertamente ventajosas, adquiriendo vida propia y carácter preferente respecto de las soluciones conocidas de la misma aplicación.For all this, that system object of the invention results from certainly advantageous features, acquiring a life of its own and preferential character with respect to known solutions of the same application.

Descripción detallada de la invenciónDetailed description of the invention

El objeto de la invención se refiere a un sistema para el montaje de tuercas con bloqueo de retención sobre el eje (1) de incorporación, por ejemplo para la sujeción de un rodamiento (2) sobre un eje (1) de gran diámetro, como representa la figura 4, o aplicaciones semejantes.The object of the invention relates to a system for mounting nuts with retention lock on the axis (1) of incorporation, for example for securing a bearing (2) on a large diameter shaft (1), as represented by the Figure 4, or similar applications.

El sistema preconizado comprende la utilización de una tuerca (3) formada con una parte axial (3.1) de superficie interior lisa y diámetro como el del eje (1) de montaje, en tanto que la parte axial (3.2) restante posee una superficie interior (4) roscada con un diámetro mayor que el eje (1) de montaje.The recommended system includes the use of a nut (3) formed with an axial surface part (3.1) smooth interior and diameter like that of the mounting shaft (1), while that the remaining axial part (3.2) has an inner surface (4) threaded with a diameter larger than the mounting shaft (1).

En correspondencia con la parte axial (3.2) de superficie interior (4) roscada se dispone un anillo cilíndrico (5), el cual determina una superficie exterior roscada en correspondencia con la rosca y el diámetro de la mencionada superficie interior (4) de la parte axial (3.2) de la tuerca, mientras que interiormente dicho anillo cilíndrico (5) posee una superficie lisa con el mismo diámetro que el eje (1) de montaje de la tuerca (3).Corresponding to the axial part (3.2) of threaded inner surface (4) a cylindrical ring (5) is arranged, which determines an external surface threaded in correspondence with the thread and the diameter of said inner surface (4) of the axial part (3.2) of the nut, while internally said cylindrical ring (5) has a smooth surface with the same diameter than the nut mounting shaft (1) (3).

El mencionado anillo cilíndrico (5) se dispone sobre el eje (1) de aplicación del montaje, con bloqueo de giro entre ambos mediante una o más chavetas (6), y con tope axial de dicho anillo cilíndrico (5) mediante un clip (7) que se dispone encajado sobre el propio eje (1), con lo cual mediante ese anillo cilíndrico (5) se determina sobre el eje (1) de montaje una zona roscada, respecto de la cual es susceptible el acoplamiento roscado de la tuerca (3), sin que el eje (1) tenga que tener un fileteado de rosca formado sobre él.Said cylindrical ring (5) is arranged on the axis (1) of application of the assembly, with rotation lock between both by one or more keys (6), and with axial stop of said cylindrical ring (5) by means of a clip (7) which is arranged embedded on the shaft itself (1), thereby using that ring cylindrical (5) a zone is determined on the mounting shaft (1) threaded, with respect to which threaded coupling is susceptible of the nut (3), without the shaft (1) having to have a filleting of thread formed on it.

Por otro lado, en la parte axial (3.1) de superficie interior lisa se hallan definidas desde el frente extremo de la tuerca (3) unas ranuras axiales (8), próximas a la superficie interior lisa de esa parte axial (3.1), mientras que desde la periferia exterior se hallan definidos hasta dichas ranuras axiales (8) unos orificios radiales (9) roscados, en los cuales se disponen unos tornillos (10), con los cuales es susceptible ejercer presión hacia el interior sobre la pared (8.1) de las mencionadas ranuras axiales (8) que queda enfrente de los orificios radiales (9).On the other hand, in the axial part (3.1) of smooth inner surface are defined from the extreme front of the nut (3) axial grooves (8), close to the surface smooth inside of that axial part (3.1), while from the outer periphery are defined up to said axial grooves (8) threaded radial holes (9), in which they are arranged screws (10), with which it is susceptible to exert pressure inwards on the wall (8.1) of the mentioned grooves axial (8) in front of the radial holes (9).

De este modo, una vez incorporada la tuerca (3) en el montaje sobre el eje (1) de aplicación, mediante acoplamiento roscado sobre el anillo cilíndrico (5), con los tornillos (10) puede establecerse un aprieto de la pared (8.1) de las ranuras axiales (8) contra el eje (1), determinando así el bloqueo de la tuerca (3) para evitar su aflojamiento espontáneo.Thus, once the nut (3) is incorporated in the mounting on the application shaft (1), by coupling threaded on the cylindrical ring (5), with the screws (10) you can establish a wall tightening (8.1) of the axial grooves (8) against the shaft (1), thus determining the lock of the nut (3) to Avoid spontaneous loosening.
