Abstract
Description
La présente invention concerne une bague élastique formant un anneau ouvert destiné à être engagé dans une gorge circulaire par modification de son diamètre, en vue d'assurer la retenue axiale d'une pièce cylindrique par rapport à l'alésage dans lequel cette pièce est emmanchée. The present invention relates to an elastic ring forming an open ring intended to be engaged in a circular groove by modifying its diameter, with a view to ensuring the axial retention of a cylindrical part with respect to the bore in which this part is fitted .
Ces bagues sont notamment utilisées pour positionner des roulements à billes. These rings are used in particular to position ball bearings.
La bague peut être placée dans une gorge de la pièce cylindrique. La pose et la dépose s'effectuent alors par augmentation du diamètre moyen de la bague. Elle peut aussi être placée dans une gorge de l'alésage, la pose et la dépose s'effectuant par diminution de son diamètre moyen. The ring can be placed in a groove in the cylindrical part. Installation and removal are then carried out by increasing the average diameter of the ring. It can also be placed in a groove in the bore, installation and removal being carried out by reducing its average diameter.
I1 est connu de donner à la section de la bague une forme trapézoidale : l'une de ses faces est perpendiculaire à son axe, tandis que l'autre présente un chanfrein conique, les flancs de la gorge ayant une forme complémentaire. La bague, du fait de son élasticité, s'engage alors dans le fond de la gorge par rapport à laquelle elle ne présente aucun jeu. On peut de la sorte parfaitement positionner la pièce cylindrique par rapport à son alésage, mais pour un seul sens de déplacement axial. I1 is known to give the section of the ring a trapezoidal shape: one of its faces is perpendicular to its axis, while the other has a conical chamfer, the sides of the groove having a complementary shape. The ring, due to its elasticity, then engages in the bottom of the groove with respect to which it has no play. In this way it is possible to perfectly position the cylindrical part with respect to its bore, but for one direction only axial displacement.
Pour assurer une retenue vis à vis des deux sens de déplacement axial, il faut prévoir une deuxième butée opposée à celle que réalise la bague élastique. To ensure a retention with respect to the two directions of axial movement, it is necessary to provide a second stop opposite to that produced by the elastic ring.
Pour résoudre ce problème, il est connu d'utiliser une bague élastique destinée à être engagée à la fois dans une gorge de la pièce cylindrique et dans une gorge de l'alésage en prévoyant un dégagement approprié pour permettre de déformer la bague en vue de son montage ou de son démontage. To solve this problem, it is known to use an elastic ring intended to be engaged both in a groove in the cylindrical part and in a groove in the bore while providing an appropriate clearance to allow the ring to be deformed in order to its mounting or dismounting.
Malheureusement, cette solution ne permet pas d'obtenir un positionnement précis. En effet, s 'il est possible d'éviter tout jeu entre la partie trapezoidale de la bague et la gorge correspondante, il n'en est pas de même pour l'autre gorge vis à vis de laquelle la bague doit nécessairement présenter un léger jeu. Compte tenu des tolérances de fabrication, il en résulte une imprécision de montage et des possibilités de déplacement en service qui peuvent être particulièrement nuisibles. C'est ainsi, par exemple, que dans une boîte de vitesses de véhicule automobile, si un roulement n'est pas correctement immobilité axialement, il est nécessaire de prévoir des jeux plus importants entre toutes les pièces en mouvement, pour tenir compte du battement axial possible de l'arbre porté par ce roulement. Unfortunately, this solution does not allow precise positioning. Indeed, if it is possible to avoid any play between the trapezoidal part of the ring and the corresponding groove, it is not the same for the other groove with respect to which the ring must necessarily have a slight clearance. Taking into account manufacturing tolerances, this results in imprecision in mounting and in-service movement possibilities which can be particularly harmful. Thus, for example, in a motor vehicle gearbox, if a bearing is not correctly immobilized axially, it is necessary to provide greater clearances between all the moving parts, to take account of the flapping possible axial of the shaft carried by this bearing.
L'invention a pour but d'apporter aux bagues connues un perfectionnement permettant d'assurer un positionnement parfait et exempt de tout jeu axial d'une pièce cylindrique par rapport à son alésage. The object of the invention is to provide known rings with an improvement making it possible to ensure perfect positioning and free from any axial play of a cylindrical part with respect to its bore.
Elle s'applique à une bague élastique consti
tuée par un anneau ouvert destiné à être engagé dans une
gorge circulaire par modification de son diamètre, les
sections transversales de la bague et de la gorge ayant
des formes complémentaires.It applies to an elastic ring made up
killed by an open ring intended to be engaged in a
circular groove by changing its diameter, the
cross sections of the ring and groove having
complementary forms.
Cette bague est caractérisée en ce qu'elle
comporte, du côté opposé à sa partie coopérant avec la gor
ge, au moins deux oreilles pourvues chacune d'un orifice
destiné à recevoir une vis de fixation.This ring is characterized in that it
has, on the side opposite its part cooperating with the gor
ge, at least two ears each provided with an orifice
intended to receive a fixing screw.
De préférence, les oreilles et leur trou de
fixation sont diamétralement opposés.Preferably, the ears and their hole
fixing are diametrically opposed.
Si la bague est prévue pour être engagée dans
une gorge d'une pièce cylindrique, les oreilles sont orien
tées vers l'extérieur.If the ring is intended to be engaged in
a throat of a cylindrical piece, the ears are orien
outside.
Si la bague est prévue pour être engagée dans
une gorge d'un alésage, les oreilles sont orientées vers
l'intérieur.If the ring is intended to be engaged in
a throat of a bore, the ears are oriented towards
the interior.

- la Fig.l est une vue de face d'un ensemble comportant une bague suivant l'invention;
- la Fig.2 est une.coupe suivant la ligne 2-2 de la Fig.l;
- la Fig.3 est une vue d'une bague représentée seule;
- la Fig.4 est une section à plus grande échelle suivant la ligne 4-4 de la Fig.3.An embodiment of the invention makes
the subject of the description which follows, with reference to the drawings
annexed in which
- Fig.l is a front view of an assembly comprising a ring according to the invention;
- Fig.2 is a section along line 2-2 of Fig.l;
- Fig.3 is a view of a ring shown alone;
- Fig.4 is a section on a larger scale along line 4-4 of Fig.3.
On a supposé l'invention appliquée au montage d'un roulement à billes 1 portant un arbre 2 d'une boîte de vitesses dont on a représenté une partie du carter 3. The invention has been assumed to be applied to the mounting of a ball bearing 1 carrying a shaft 2 of a gearbox, part of the housing 3 of which is shown.
Le roulement à billes 1 comporte une bague. The ball bearing 1 has a ring.
extérieure 4 munie d'une gorge circulaire 5. Cette dernière présente une section trapézoldale avec un flanc 6 perpendiculaire à l'axe X-X et un flanc 7 conique (Fig.2).outer 4 provided with a circular groove 5. The latter has a trapezoidal section with a sidewall 6 perpendicular to the axis X-X and a conical sidewall 7 (Fig.2).
Dans cette gorge s'engage une bague élastique 8 en forme d'anneau ouvert (Fig.3), limitée par deux faces parallèles 9,10 dont l'une présente, vers le centre, un chanfrein conique 11 correspondant au flanc conique 7 de la gorge. In this groove engages an elastic ring 8 in the form of an open ring (FIG. 3), bounded by two parallel faces 9, 10 one of which has, towards the center, a conical chamfer 11 corresponding to the conical flank 7 of the throat.
La bague 8 comporte, de manière habituelle, deux orifices 12 prévus pour recevoir un outil destiné à accroître son diamètre en vue de sa mise en place dans la gorge 5 ou de son dégagement. The ring 8 comprises, in the usual way, two orifices 12 provided for receiving a tool intended to increase its diameter with a view to its positioning in the groove 5 or its release.
Elle comporte en outre deux oreilles 13, diamétralement opposées, pourvues chacune d'un orifice 14 permettant son immobilisation sur le carter 3 au moyen de vis 15. It further comprises two diametrically opposite ears 13, each provided with an orifice 14 allowing it to be immobilized on the casing 3 by means of screws 15.
Grâce à la bague ainsi décrite, on réalise de façon parfaite le positionnement et l'immobilisation de la bague extérieure 4 du roulement à billes 1. En effet, la bague élastique 8, du fait de la forme trapézoldale de sa section transversale et grâce à son élasticité, se bloque parfaitement dans la gorge 5. La fixation de la bague 8 par les vis 15, permet ensuite de faire coincider de façon parfaite le flanc 6 de la gorge 5 avec la surface extérieure 16 du carter 3. Thanks to the ring thus described, the positioning and immobilization of the outer ring 4 of the ball bearing 1 is perfectly achieved. In fact, the elastic ring 8, due to the trapezoidal shape of its cross section and thanks to its elasticity is perfectly blocked in the groove 5. The fixing of the ring 8 by the screws 15 then makes it possible to make the flank 6 of the groove 5 coincide perfectly with the external surface 16 of the casing 3.
Pour que la fixation de la bague 8 sur le carter 3 se fasse sans contraite susceptible d'entraîner un dégagement partiel de la bague de sa gorge, il est nécessaire de prévoir un jeu relativement important entre le diamètre des vis 15 et celui des orifices 14. So that the fixing of the ring 8 on the casing 3 is done without constraint likely to cause a partial release of the ring from its groove, it is necessary to provide a relatively large clearance between the diameter of the screws 15 and that of the orifices 14 .
Dans l'exemple qui vient d'être décrit, la bague présente une section trapézoidale ayant un flanc perpendiculaire à son axe et un autre flanc conique. In the example which has just been described, the ring has a trapezoidal section having a flank perpendicular to its axis and another conical flank.
On comprendra cependant que l'invention s'applique également à des bagues de section différente. It will however be understood that the invention also applies to rings of different section.
