DESCRIPCIONDESCRIPTION

Rodamiento de pinon de ataque Objeto de la invencionPinion Attack Bearing Object of the Invention

La presente invencion se encuadra en el sector de la tecnica referente a los rodamientos y mas concretamente a rodamientos de rodillos conicos de acoplamiento en ejes diferenciales.The present invention is framed in the sector of the technique relating to bearings and more specifically to conical roller bearings for coupling in differential shafts.

El objeto de la invencion es desarrollar un rodamiento, que incorpora un anillo de union en la parte interior de los aros interiores del rodamiento, para permitir el montaje/desmontaje del mismo en una sola operacion eliminando posibles interferencias con el eje del pinon de ataque.The object of the invention is to develop a bearing, which incorporates a union ring inside the inner rings of the bearing, to allow the assembly / disassembly thereof in a single operation eliminating possible interference with the axis of the pinion of attack.

Antecedentes de la invencionBackground of the invention

En la actualidad este tipo de rodamientos montados en el pinon de ataque, disponen de un anillo que une los aros interiores por la parte exterior de los mismos; este anillo puede romperse con facilidad durante la operacion de extraccion, quedando el extremo del aro clavado en el eje del pinon de ataque, dificultando por consecuencia la extraccion.At present, these types of bearings mounted on the attack pinon have a ring that joins the inner rings on the outside of them; This ring can break easily during the extraction operation, leaving the end of the ring pinned to the axis of the pinion of attack, thus making removal difficult.

La rotura del anillo que une los aros interiores viene propiciada porque la union se efectua por la parte exterior de los aros; ello implica que, para poder realizarse dicha union, el espesor del anillo debe ser muy reducido, generandose una holgura considerable, y quedando las puntas de los extremos de los aros interiores registradas directamente con el eje del pinon de ataque. De este modo, resulta muy dificultosa su extraccion en una sola operacion.The rupture of the ring that joins the inner rings is caused because the union is made by the outer part of the rings; this implies that, in order to be able to realize said union, the thickness of the ring must be very reduced, generating a considerable clearance, and leaving the ends of the ends of the inner rings registered directly with the axis of the pinion of attack. Thus, it is very difficult to extract them in a single operation.

En este tipo de rodamientos es necesario el uso de una prensa para realizar el montaje del anillo, resultando muy complicado verificar su correcto montaje.In this type of bearings it is necessary to use a press to mount the ring, it is very difficult to verify its correct assembly.

Descripcion de la invencionDescription of the invention

Con la finalidad de aportar una solucion a los inconvenientes citados, se ha ideado un rodamiento de pinon de ataque del tipo de los comprendidos por una carcasa que incorpora dos rodamientos de rodillos conicos de una hilera, unidos entre si a traves de un anillo, incorporando un mecanizado practicado en la parte interior de los extremos del aro interior derecho y del aro interior izquierdo, destinado para el acoplamiento de un anillo, realizando la union entre los aros interiores, enfrentados y unidos entre si, de forma consistente y eliminando holguras que pudieran afectar la resistencia a la extraccion.In order to provide a solution to the aforementioned drawbacks, an attack pinion bearing of the type comprising a housing that incorporates two single-row tapered roller bearings, joined together through a ring, has been devised a machining practiced in the inner part of the ends of the right inner ring and the left inner ring, intended for the coupling of a ring, making the union between the inner rings, facing and joined together, in a consistent manner and eliminating gaps that could affect the resistance to extraction.

El mecanizado practicado en los extremos del aro interior derecho y del aro interior izquierdo, consiste en una ranura rectangular, con las aristas rematadas en radio, quedando posicionada dicha ranura muy proxima a dicho extremo, practicando un rebaje en la punta de dichos extremos, previsto, para el acoplamiento del anillo, quedando posicionado entre las ranuras rectangulares y el diametro del eje del pinon de ataque.The machining practiced at the ends of the right inner ring and the left inner ring, consists of a rectangular groove, with the edges finished in radius, said groove being positioned very close to said end, practicing a recess in the tip of said ends, provided , for the coupling of the ring, being positioned between the rectangular grooves and the diameter of the axis of the pinion of attack.

El montaje del anillo realizado por la parte interior de los aros, ofrece mayor resistencia a la rotura, dotando al conjunto gran resistencia a la extraccion.The assembly of the ring made by the inner part of the rings, offers greater resistance to breakage, giving the whole great resistance to extraction.

El montaje del anillo, al realizarse por la parte interior de los aros, permite un montaje manual sin necesidad de la utilizacion de una prensa, siendo posible verificar su correcto montaje.The assembly of the ring, when carried out through the inner part of the rings, allows manual assembly without the need for the use of a press, being possible to verify its correct assembly.

El contenido del documento prioritario se entiende comprendido en su integridad y por referencia en la presente solicitud.The content of the priority document is understood to be understood in its entirety and by reference in the present application.

Ventajas de la invencionAdvantages of the invention

El rodamiento de pinon de ataque, que se presenta, aporta multiples ventajas sobre los actualmente utilizados, siendo la mas importante la de realizar la union de los aros por la parte interior de los mismos, a traves de un anillo, proporcionando al rodamiento gran resistencia a la extraccion.The attack pinion bearing, which is presented, provides multiple advantages over those currently used, the most important being to perform the union of the rings on the inside of them, through a ring, providing the bearing with great resistance to the extraction.

Como ventaja importante, derivada de la anterior, es la eliminacion de holguras en el acoplamiento del anillo, al realizarse la union de los aros por la parte interior de los mismos.As an important advantage, derived from the previous one, is the elimination of gaps in the coupling of the ring, when the rings are joined by the inside of the rings.

Como ventaja importante anadir que el montaje del anillo se realiza manualmente sin necesidad de usar una prensa, siendo posible verificar su correcto montaje.As an important advantage to add that the assembly of the ring is done manually without using a press, being possible to verify its correct assembly.
