Description
L'invention concerne une bague de guidage et un procédé de montage d'une telle bague dans un alésage. ARRIERE-PLAN TECHNOLOGIQUE DE L'INVENTION Dans le domaine des trains d'atterrissages, de nombreuses bagues de guidage sont utilisées pour guider des axes introduits dans des alésages cylindriques, ou pour centrer une pièce sur un support cylindrique circulaire (par exemple une couronne portant des actionneurs de freinage enfilée sur un essieu). Ces bagues sont par exemple réalisées en bronze fritté, en alliage cupro- nickel, ou encore en polymère thermoplastique tel que du Polyétheréthercétone (PEEK) chargé avec des fibres de carbone et/ou du polyimide. En général, la bague est montée serrée dans son alésage. L'intensité du serrage va- rie, mais il est souvent important (H7p6). A cette fin, il est connu de : - Provoquer un rétreint de la bague en la refroidissant (par exemple en la plongeant dans de l'azote liquide) ; - Provoquer une expansion de l'alésage (par exemple par chauffage à induction) ; - monter la bague à force dans l'alésage (presse) ; - Réaléser le diamètre interne de la bague après montage et équilibre thermique.The invention relates to a guide ring and a method of mounting such a ring in a bore. BACKGROUND OF THE INVENTION In the field of landing gear, numerous guide rings are used to guide shafts introduced into cylindrical bores, or to center a workpiece on a circular cylindrical support (for example a bearing ring braking actuators threaded onto an axle). These rings are for example made of sintered bronze, cupronickel alloy, or thermoplastic polymer such as polyetheretherketone (PEEK) loaded with carbon fibers and / or polyimide. In general, the ring is mounted tight in its bore. The intensity of the tightening varies, but it is often important (H7p6). To this end, it is known to: - cause a narrowing of the ring by cooling (for example by immersing in liquid nitrogen); - cause an expansion of the bore (for example by induction heating); - mount the ring forcefully in the bore (press); - Carry out the internal diameter of the ring after assembly and thermal equilibrium.
Ces opérations sont lourdes, et malgré les moyens mis en oeuvre, il a été observé des migrations de certaines bagues dans des conditions de services particulièrement sévères, notamment lors un échauffement local important après un freinage appuyé.These operations are cumbersome, and despite the means implemented, it has been observed migrations of certain rings under particularly severe service conditions, especially during a significant local heating after sustained braking.
OBJET DE L'INVENTION L'invention vise à proposer une bague de guidage et un procédé de montage associé permettant de simplifier le montage de la bague et diminuer le risque de migration de la bague.OBJECT OF THE INVENTION The invention aims to provide a guide ring and an associated mounting method for simplifying the mounting of the ring and reduce the risk of migration of the ring.
PRESENTATION DE L'INVENTION En vue de la réalisation de ce but on propose une bague destinée à être insérée dans un alésage pour former un palier de guidage d'un arbre ou équivalent introduit dans l'alésage, la bague comportant une partie courante annulaire avec un diamètre interne et un diamètre ex- terne, la partie courante présentant à l'une de ses extrémités une pluralité de doigts flexibles s'étendant dans le prolongement de la partie courante et comportant chacun un redan d'extrémité dépassant du diamètre externe de la partie courante et adapté à s'engager dans une gorge de l'alésage. Ainsi, lors du montage, la bague est poussée dans l'alésage, forçant ainsi les doigts à fléchir vers l'intérieur de l'alésage, jusqu'à ce que les redans vien- vent prendre place dans la gorge sous l'effet de la dé- tente des doigts. Lorsque l'arbre ou l'axe à guider est introduit dans la bague, il empêche la flexion des doigts, interdisant ainsi aux redans de s'échapper de la gorge. On obtient ainsi une immobilisation axiale de la bague empêchant toute migration de celle-ci. On peut dès lors monter la bague avec un serrage beaucoup moins important. DESCRIPTION DES FIGURES L'invention sera mieux comprise à la lecture de la description détaillée qui suit d'un mode particulier de réalisation de l'invention en référence aux figures des dessins annexés parmi lesquelles : - la figure 1 est une vue en perspective d'une bague de guidage selon l'invention ; - la figure 2 est une vue en coupe de la bague de la figure 1 en cours de montage dans son alésage ; - la figure 3 est une vue en coupe de la bague en place dans son alésage. DESCRIPTION DETAILLEE D'UN MODE PARTICULIER DE REALISATION DE L'INVENTION En référence à la figure 1, la bague 1 de l'invention, ici une bague en cupro-nickel, comporte une partie courante 2 annulaire avec une surface cylindrique externe d'un diamètre extérieur donné, et une surface in- terne d'un diamètre interne donné. La partie courante an- nulaire 2 est terminée d'un côté par une collerette 4, et de l'autre côté par une pluralité de doigts 5 (un seul est référencé sur la figure pour alléger celle-ci) qui s'étendent dans le prolongement de la partie courante an- nulaire 2 et qui présentent une extrémité en forme de re- dan 6 tourné vers l'extérieur et qui dépasse du diamètre externe de la partie courante. Ici, les doigts 5 sont obtenus en pratiquant des fentes 7 à intervalles réguliers dans l'extrémité de la bague 1 pour séparer deux doigts 5 adjacents. Les doigts 5 ainsi découpés sont flexibles. Comme cela est représenté à la figure 2, la bague 1 est mise en place dans un alésage 10 dans lequel une gorge 11 a été pratiquée pour recevoir les redans 6 des doigts 5. Lors de l'enfoncement de la bague 1, les redans 6 prennent appui contre l'alésage, forçant ainsi les doigts 5 à fléchir vers l'intérieur, jusqu'à ce que les redans 6 parviennent au droit de la gorge 11 dans laquelle ils viennent finalement se loger. On voit à la fi- Bure 3 la bague 1 en place sur l'alésage 10, les redans 6 ayant pris place dans la gorge 11. Un axe 20 a été introduit à l'intérieur de la bague 1, la bague formant un palier pour l'axe 20. Les doigts 5 qui avaient fléchi lors de la mise en place de la bague sont revenus à leur posi- tion au repos, et le diamètre interne Dl est entièrement dégagé, formant ainsi un appui pour l'axe 20. Sur la figure 3, on remarque que l'axe 20 a un diamètre externe tel qu'il empêche toute flexion des doigts 5, de sorte que les redans 6 sont immobilisés dans la gorge 11 et forment donc un arrêt axial de la bague 1, qui ne peut plus migrer. Il est dès lors inutile de prévoir un serrage important entre la bague et l'alésage. On se contentera en pratique d'un serrage (par exemple de type H7m6 ou infé- rieur) permettant l'enfoncement de la bague 1 dans l'alésage 10 sans refroidissement de la bague et/ou expansion de l'alésage, ce qui simplifie considérablement le montage de la bague. Le serrage ainsi diminué permettra la plupart du temps de supprimer l'étape de réalésage habituelle après un montage à force très serré. En outre, le serrage ainsi diminué facilite le retrait de la bague. Dans certains cas, on pourra se contenter d'un simple ajustement glissant. L'invention n'est pas limitée à ce qui vient d'être décrit mais englobe au contraire toute variante entrant dans le cadre défini par les revendications. En particulier, bien que la bague illustrée com- porte une collerette, la bague de l'invention pourra ne pas comporter de collerette.PRESENTATION OF THE INVENTION With a view to achieving this object, a ring intended to be inserted into a bore is provided to form a guide bearing for a shaft or equivalent introduced into the bore, the ring comprising an annular running portion with an inner diameter and an outer diameter, the running portion having at one of its ends a plurality of flexible fingers extending in the extension of the running portion and each having an end step protruding from the outer diameter of the current portion and adapted to engage a groove of the bore. Thus, during assembly, the ring is pushed into the bore, thus forcing the fingers to bend towards the inside of the bore, until the redans come to take place in the groove under the effect of the looseness of the fingers. When the shaft or the axis to be guided is introduced into the ring, it prevents bending of the fingers, thus preventing the rams from escaping the groove. This results in axial immobilization of the ring preventing any migration thereof. We can then mount the ring with a much smaller tightening. DESCRIPTION OF THE FIGURES The invention will be better understood on reading the following detailed description of a particular embodiment of the invention with reference to the figures of the appended drawings in which: FIG. 1 is a perspective view of a guide ring according to the invention; - Figure 2 is a sectional view of the ring of Figure 1 being mounted in its bore; - Figure 3 is a sectional view of the ring in place in its bore. DETAILED DESCRIPTION OF A PARTICULAR EMBODIMENT OF CARRYING OUT THE INVENTION With reference to FIG. 1, the ring 1 of the invention, here a cupro-nickel ring, comprises an annular running portion 2 with an outer cylindrical surface of a given external diameter, and an internal surface of a given internal diameter. The annular running portion 2 is terminated on one side by a flange 4, and on the other side by a plurality of fingers 5 (only one is referenced in the figure to alleviate this) which extend into the extending the annular running portion 2 and having a recess-shaped end 6 facing outward and protruding from the outer diameter of the running portion. Here, the fingers 5 are obtained by making slits 7 at regular intervals in the end of the ring 1 to separate two adjacent fingers 5. The fingers 5 thus cut are flexible. As shown in FIG. 2, the ring 1 is put into place in a bore 10 in which a groove 11 has been made to receive the steps 6 of the fingers 5. During the insertion of the ring 1, the steps 6 bear against the bore, forcing the fingers 5 to bend inwardly, until the notches 6 reach the right of the groove 11 in which they finally come to lodge. In FIG. 3, it is seen that the ring 1 is in place on the bore 10, the steps 6 having taken place in the groove 11. An axis 20 has been introduced inside the ring 1, the ring forming a bearing for the axis 20. The fingers 5 which had bent during the establishment of the ring returned to their position at rest, and the internal diameter Dl is completely clear, thus forming a support for the axis 20. In FIG. 3, it can be seen that the axis 20 has an external diameter such that it prevents any bending of the fingers 5, so that the steps 6 are immobilized in the groove 11 and thus form an axial stop of the ring 1, who can no longer migrate. It is therefore unnecessary to provide a significant tightening between the ring and the bore. In practice, it will be sufficient to tighten (for example of the type H7m6 or below) allowing the ring 1 to be inserted into the bore 10 without cooling the ring and / or expanding the bore, which simplifies considerably mounting the ring. The reduction thus reduced will most of the time eliminate the usual reborage step after a very tight force fit. In addition, the thus reduced tightening facilitates the removal of the ring. In some cases, we can settle for a simple sliding adjustment. The invention is not limited to what has just been described, but on the contrary covers any variant within the scope defined by the claims. In particular, although the illustrated ring has a flange, the ring of the invention may not have a flange.
En outre, bien qu'ici la bague illustrée est en cupro-nickel, elle pourra être réalisée dans d'autres matériaux, comme indiqué précédemment. De plus, bien qu'ici les doigts soient adjacents les uns aux autres de sorte que leur surface interne constitue une partie de la surface d'appui de l'axe in- troduit dans la bague, on pourra utiliser un nombre plus réduit de doigts, de préférence régulièrement répartis, avec au minimum deux doigts diamétralement opposés.In addition, although here the ring illustrated is cupro-nickel, it can be made in other materials, as indicated above. Moreover, although here the fingers are adjacent to each other so that their inner surface constitutes a part of the bearing surface of the axis introduced into the ring, it will be possible to use a smaller number of fingers. , preferably regularly distributed, with at least two diametrically opposed fingers.
