Description

Tuerca corredera en ranura para la fijación de un componente en una estructura de soporte.Sliding nut in groove for fixing a component in a support structure.

La invención se refiere a una tuerca corredera en ranura para la fijación de un componente en una estructura de soporte, que está constituida por un cuerpo en forma de paralelepípedo o en forma de rombo, que contiene al menos un taladro roscado, en el que engrana un bulón roscado que atraviesa el componente a fijar, estando fijado en el cuerpo de la tuerca corredera en ranura una pieza moldeada, que contiene un taladro, cuyo diámetro es menor que el diámetro exterior roscado del bulón roscado.The invention relates to a sliding nut in groove for fixing a component in a structure support, which is constituted by a body in the form of parallelepiped or rhombus shaped, containing at least one drill  threaded, which meshes a threaded bolt that crosses the component to be fixed, being fixed in the nut body Sliding in a groove a molded part, which contains a drill, whose diameter is smaller than the threaded outer diameter of the bolt screwed.

En muchos campos de la técnica es habitual utilizar tuercas correderas en ranura para la fijación de componentes en estructuras de soporte, que se insertan en ranuras correspondientes de la estructura respectiva. Estas tuercas correderas en ranura tienen al menos un taladro roscado para un bulón roscado, que atraviesa el componente a fijar. Así, por ejemplo, a partir del de las publicaciones DE-A-2 908 823 o EP-B-0 182 191 se deduce la conexión de faldillas, de chapas de subsuelo o de una instalación de accionamiento pesada en el chasis de un vehículo ferroviario con la ayuda de tuercas correderas en ranura. Sobre todo con respecto a una fijación fiable en la dirección longitudinal de la tuerca -retención fija del componente también en el caso de que se produzcan fuerzas longitudinales- es esencial impulsar la pareja formada por la ranura de la estructura y la tuerca corredera en ranura con una fuerza de fijación definida, que se puede generar a través de un par de torsión de apriete correspondiente del bulón roscado. En el caso de utilización de pegamentos conocidos, que colaboran con los pasos de rosca, para el aseguramiento necesario del bulón roscado, pueden surgir problemas con relación a la fijación fiable deseada, puesto que los pegamentos, en general, eliminan una porción apenas predeterminable del par de torsión de apriete, que no está disponible entonces como fuerza de fijación para la ranura y la tuerca corredera en ranura.In many fields of the technique it is usual use sliding nuts in groove for fixing components in support structures, which are inserted into slots corresponding of the respective structure. These nuts Slot grooves have at least one threaded hole for a threaded bolt, which passes through the component to be fixed. So by example, from the publications DE-A-2 908 823 or EP-B-0 182 191 the connection is deducted of skirts, subsoil plates or an installation of heavy drive on the chassis of a railway vehicle with the Sliding nut support in groove. Especially with respect to reliable fixing in the longitudinal direction of the nut - fixed retention of the component also in the event that produce longitudinal forces - it is essential to boost the couple formed by the groove of the structure and the sliding nut in groove with a defined fixing force, which can be generated at through a corresponding tightening torque of the bolt screwed. In the case of using known glues, which collaborate with the thread steps, for the necessary assurance of the threaded bolt, problems may arise in relation to the desired reliable fixation, since the adhesives, in general, eliminate a barely predetermined portion of the torque of tighten, which is not available as a clamping force for the groove and the sliding nut in the groove.

Se conoce por la publicación DE 196 28 582 A1 una tuerca corredera en ranura con las características del tipo mencionadas al principio. Según este estado de la técnica, la tuerca corredera en ranura debe apoyarse durante el montaje por fricción dentro de la ranura, alineada dado el caso también verticalmente, de la estructura de soporte. A tal fin, en una escotadura en forma de ranura de la tuerca corredera en ranura se inserta una pieza moldeada de plástico, que presenta una lengüeta que se apoya de forma elástica contra el fondo de la ranura. Esta pieza moldeada tiene un taladro, que presenta una medida inferior con respecto al diámetro exterior de la rosca de un bulón roscado, de manera que la pieza moldeada de plástico se ensancha radialmente durante la introducción del bulón roscado en el taladro y se fija en este caso en la escotadura anular de la tuerca corredera en ranura.It is known from publication DE 196 28 582 A1 a Slot nut in groove with type features mentioned at the beginning. According to this state of the art, the Sliding nut in groove should be supported during assembly by friction inside the groove, aligned if necessary vertically, of the support structure. To that end, in a slot-shaped recess of the sliding nut in slot is insert a molded piece of plastic, which features a tongue which rests elastically against the bottom of the groove. Is molded part has a drill, which has a lower measurement with respect to the outer diameter of the thread of a threaded bolt, so that the plastic molded part widens radially during the introduction of the threaded pin in the hole and it is fixed in this case in the annular recess of the sliding nut in groove.

La invención tiene el cometido de configurar una tuerca corredera en ranura del tipo indicado al principio a través de medios lo más sencillos posible para que se pueda conseguir siempre una fuerza de fijación definida para la pareja formada por la ranura de la estructura y la tuerca corredera en ranura.The invention has the task of configuring a Slot nut in slot of the type indicated at the beginning through of means as simple as possible so that it can be achieved always a definite fixing force for the couple formed by the groove of the structure and the sliding nut in groove.

Este cometido se soluciona según la invención porque la pieza moldeada está formada por una tira perfilada de acero para muelles, donde el taladro está dispuesto en la región del perfilado de esta tira y presenta un diámetro, que es mayor que el diámetro del núcleo roscado del bulón roscado. Por medio de la tira especial de acero para muelles, en la tuerca corredera en ranura está integrada de una manera ventajosa la función del seguro del tornillo (tuerca corredera en ranura de cierre automático).This task is solved according to the invention. because the molded part is formed by a profiled strip of spring steel, where the drill is arranged in the region of the profiling of this strip and has a diameter, which is greater than The diameter of the threaded core of the threaded bolt. Through special spring steel strip, on the sliding nut in slot is advantageously integrated the insurance function of the screw (sliding nut in self-closing groove).

Las configuraciones ventajosas de la invención están indicadas en las reivindicaciones dependientes.The advantageous configurations of the invention are indicated in the dependent claims.

Por otra parte, la invención se describe en detalle con la ayuda de un ejemplo de realización, que está representado de forma esquemática en el dibujo. En este caso:Moreover, the invention is described in detail with the help of an embodiment example, which is represented schematically in the drawing. In this case:

La estructura de soporte 2, formada a modo de ejemplo por un perfil prensado por extrusión, contiene una ranura 2a, en la que está dispuesta una tuerca corredera en ranura. El cuerpo 3 aquí en forma de paralelepípedo de esta tuerca corredera en ranura contiene un taladro roscado 4, siendo posibles varios de tales taladros. En el taladro roscado 4 engrana un bulón roscado 5, que atraviesa el componente 1 a fijar.The support structure 2, formed as a example by an extrusion pressed profile, it contains a groove 2a, in which a sliding nut in slot is arranged. The body 3 here in the form of a parallelepiped of this sliding nut slot contains a threaded hole 4, several of which are possible such drills. In the threaded hole 4 engage a threaded bolt 5, which passes through component 1 to be fixed.

En el cuerpo 3 de la tuerca corredera en ranura está fijada una pieza moldeada en forma de una tira perfilada 6 de acero para muelles. El perfilado de la tira 6 de acero para muelles está formado con preferencia por un abombado transversal. La tira 6 presenta en la región de su perfilado un taladro 6b, cuyo diámetro es mayor que el diámetro del núcleo roscado y menor que el diámetro exterior roscado del bulón roscado 5. De esta manera, el bulón roscado 5 y la tira 6 de acero para muelles colaboran con efecto de sujeción (tuerca corredera en ranura de cierre automático). Se consigue una fijación especialmente sencilla de la tira 6 en el cuerpo 3 de la tuerca corredera en ranura porque la tira 6 está retenida lateralmente en escotaduras 7 de la tuerca corredera en ranura y presenta chaflanes 6c que se apoyan contra los lados frontales 8 de la tuerca corredera en ranura.In body 3 of the slot nut a molded part in the form of a profiled strip 6 of spring steel. Profiling of steel strip 6 for springs It is preferably formed by a transverse bulge. Strip 6 it presents in the region of its profiling a drill 6b, whose diameter is larger than the diameter of the threaded core and smaller than the diameter threaded outer of the threaded bolt 5. In this way, the bolt threaded 5 and steel strip 6 for springs collaborate with the effect of clamping (sliding nut in self-closing groove). I know it achieves an especially simple fixation of the strip 6 in the Slot nut body 3 in groove because strip 6 is retained laterally in recesses 7 of the sliding nut in groove and features 6c chamfers that rest against the sides 8 of the sliding nut in the groove.
