Description

DESCRIPCIÓN  DESCRIPTION
Rodamiento de piñón de ataque Objeto de la invención  Attack pinion bearing Object of the invention
La presente invención se encuadra en el sector de la técnica referente a los rodamientos y más concretamente a rodamientos de rodillos cónicos de acoplamiento en ejes diferenciales. The present invention falls within the field of the art concerning bearings and more specifically to tapered roller bearings coupling on differential axes.
El objeto de la invención es desarrollar un rodamiento, que incorpora un anillo de unión en la parte interior de los aros interiores del rodamiento, para permitir el montaje/desmontaje del mismo en una sola operación eliminando posibles interferencias con el eje del piñón de ataque. The object of the invention is to develop a bearing, which incorporates a joint ring in the inner part of the inner rings of the bearing, to allow assembly / disassembly thereof in a single operation eliminating possible interference with the axis of the attack pinion.
Antecedentes de la invención BACKGROUND OF THE INVENTION
En la actualidad este tipo de rodamientos montados en el piñón 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 operación de extracción, quedando el extremo del aro clavado en el eje del piñón de ataque, dificultando por consecuencia la extracción. At present this type of bearings mounted on the attack pinion, have a ring that joins the inner rings on the outside of them; this ring can easily break during the extraction operation, leaving the end of the ring nailed to the axis of the attack pinion, making extraction difficult.
La rotura del anillo que une los aros interiores viene propiciada porque la unión se efectúa por la parte exterior de los aros; ello implica que, para poder realizarse dicha unión, el espesor del anillo debe ser muy reducido, generándose una holgura considerable, y quedando las puntas de los extremos de los aros interiores registradas directamente con el eje del piñón de ataque. De este modo, resulta muy dificultosa su extracción en una sola operación. The rupture of the ring that joins the inner rings is propitious because the union is made by the outside of the rings; this implies that, in order to be able to perform said union, the thickness of the ring must be very small, generating a considerable clearance, and the tips of the ends of the inner rings remaining registered directly with the axis of the attack pinion. In this way, 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 assemble the ring, making it very difficult to verify its correct assembly.

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 próxima 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 diámetro del eje del piñón de ataque. In order to provide a solution to the aforementioned drawbacks, an attack pinion bearing of the type comprised of a casing incorporating two single row tapered roller bearings, joined together through a ring, incorporating a machining practiced on the inside of the ends of the inner ring right and left inner ring, intended for the coupling of a ring, making the union between the inner rings, faced and joined together, consistently and eliminating gaps that could affect the resistance to extraction. The machining practiced on the ends of the inner right 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, foreseen , for the coupling of the ring, being positioned between the rectangular grooves and the diameter of the axis of the attack pinion.
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 extracción. 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 utilización de una prensa, siendo posible verificar su correcto montaje.
