Abstract

The mounting for a ball bearing (1) in a housing (2) has an elastomeric ring (3) inserted under a pre-load in the gap between the exterior surface of the bearing and the interior surface of the housing. The outer surface of the bearing and-or the inner surface of the housing have retaining formations to engage the elastomer ring and provide a resistance to axial loads.

Description

Liaison entre un premier élément de machine et second élément de machine, en particulier entre une <B>bague de roulement et un logement.</B> Link between a first machine element and a second machine element, in particular between a bearing ring and a housing. </ B>

L'invention concerne une liaison entre un premier élément de machine, particulier une bague de roulement, et un second élément de machine, en particulier un corps formant logement, comprenant - un premier élément de machine comportant une surface extérieure ; un second élément de machine comportant une surface intérieure qui est tournée vers la surface extérieure du premier élément de machine, la surface intérieure couvrant dans une large mesure la surface extérieure ; - un élastomère qui est inséré sous précontrainte dans un espace de montage prévu entre la surface extérieure du premier élément de machine et la surface intérieure du second élément de machine. The invention relates to a connection between a first machine element, particularly a bearing race, and a second machine element, in particular a housing body, comprising: - a first machine element having an outer surface; a second machine member having an inner surface which faces the outer surface of the first machine member, the inner surface substantially covering the outer surface; an elastomer which is prestressed into a mounting space provided between the outer surface of the first machine member and the inner surface of the second machine member.

Une liaison du type indiqué en introduction est connue par exemple par le document DE 196 45 530<B>AI.</B> Dans ce document, un roulement et un corps formant logement sont liés l'un à l'autre au moyen d'une couche d'élastomère; le contour extérieur du roulement et le contour intérieur du corps formant logement sont mutuellement adaptés et leur surface n'est pas plane. Une couche d'élastomère est insérée sous pression dans l'espace qui subsiste entre la bague de roulement et le corps formant logement. Du fait de la configuration non plane des surfaces extérieure et intérieure en vis-à-vis, du roulement et du corps formant logement, on obtient une certaine stabilité à l'encontre de déplacements axiaux relatifs entre le roulement et le corps formant logement. A connection of the type indicated in the introduction is known for example from DE 196 45 530. In this document, a bearing and a housing body are connected to one another by means of an elastomer layer; the outer contour of the bearing and the inner contour of the housing body are mutually adapted and their surface is not flat. An elastomer layer is inserted under pressure into the space remaining between the race and the housing body. Due to the non-planar configuration of the outer and inner surfaces facing each other, the bearing and the housing body, a certain stability is obtained against relative axial displacements between the bearing and the housing body.

Un inconvénient de cette solution connue réside dans le fait mobilité axiale du roulement par rapport au logement est limitée par forces de frottement de l'élastomère précontraint agissant sur la bague de roulement extérieure et sur la surface intérieure du corps formant loge ment. De ce fait, la solution connue n'est pas adaptée pour des charges axiales élevées. A disadvantage of this known solution lies in the fact that axial mobility of the bearing relative to the housing is limited by frictional forces of the prestressed elastomer acting on the outer race and on the inner surface of the housing body. As a result, the known solution is not suitable for high axial loads.

Partant de là, la présente invention a pour objectif de perfectionner une liaison du type indiqué en introduction, de manière à permettre la transmission d'efforts axiaux plus importants entre un premier élément de machine et un second élément de machine et à garantir un fonctionnement sans problème. From this, the present invention aims to improve a connection of the type indicated in the introduction, so as to allow the transmission of greater axial forces between a first machine element and a second machine element and to ensure operation without problem.

Cet objectif est atteint conformément à l'invention par le fait que des évidements et/ou des surélévations sont aménagés dans la surface extérieure du premier élément de machine et/ou dans la surface intérieure second élément de machine. This object is achieved according to the invention in that recesses and / or elevations are provided in the outer surface of the first machine element and / or in the inner surface of the second machine element.

Grâce à l'agencement selon l'invention on obtient, à la différence de l'état connu de la technique, par des évidements et des surélévations localisés, une meilleure liaison entre l'élastomère et le premier ou le second élément de machine, qui est en mesure de supporter ou de transmettre une force axiale plus importante. Thanks to the arrangement according to the invention, unlike the known state of the art, localized recesses and elevations result in a better connection between the elastomer and the first or the second machine element, which is able to support or transmit a greater axial force.

De préférence, les évidements sont des trous qui sont répartis, de préférence de manière équidistante, sur le pourtour de la surface extérieure et de la surface intérieure. Les surélévations peuvent être conformées par exemple en boutons, en forme de calotte sphérique, qui sont réparties de préférence de manière équidistante sur le pourtour de la surface extérieure et de la surface intérieure. Preferably, the recesses are holes which are distributed, preferably equidistantly, around the outer surface and the inner surface. The raised portions may be shaped, for example, into spherical cap shaped knobs, which are preferably distributed equidistantly around the periphery of the outer surface and the inner surface.

De manière avantageuse, les évidements et/ou les surélévations sont disposés de manière décalée sur la largeur de la surface intérieure et de la surface extérieure. Advantageously, the recesses and / or the elevations are arranged offset on the width of the inner surface and the outer surface.

Selon une caractéristique supplémentaire de l'invention, la sur face intérieure et la surface extérieure ont de préférence un contour essentiellement cylindrique. Une telle conformation a pour avantage qu'elle permet de fabriquer très simplement les surfaces réceptrices concernées pour l'élastomère dans le premier et le second élément de machine. According to a further feature of the invention, the inner face and the outer surface preferably have a substantially cylindrical contour. Such a conformation has the advantage that it makes it possible to very simply manufacture the receiving surfaces concerned for the elastomer in the first and the second machine element.

Selon perfectionnement de l'invention, le premier élément de machine est la bague extérieure d'un roulement et la surface extérieure de la bague extérieure est formée par une bague qui est montée sur ladite bague extérieure et dans laquelle sont usinés les évidement ou les surélévations. Untel agencement permet d'utiliser des roulements de type standard, sans modification particulière, pour la mise en oeuvre de la liaison selon l'invention. According to an improvement of the invention, the first machine element is the outer ring of a bearing and the outer surface of the outer ring is formed by a ring which is mounted on said outer ring and in which the recesses or the elevations are machined. . Such an arrangement allows the use of standard type bearings, without particular modification, for the implementation of the connection according to the invention.

Les dessins représentent des exemples de réalisation de l'invention. The drawings show exemplary embodiments of the invention.

La figure 1 montre une coupe transversale schématique d'une liaison comprenant un roulement, l'élastomère et un corps formant loge ment ; La figure 2 représente une variante d'agencement et la figure 3 montre une vue de dessus partielle de la surface extérieure du premier élément de machine. Figure 1 shows a schematic cross section of a linkage including a bearing, the elastomer and a housing body; Figure 2 shows an alternative arrangement and Figure 3 shows a partial top view of the outer surface of the first machine member.

La figure 1 représente un roulement, dont la bague extérieure 1 et est liée à un corps formant logement 2. La liaison est réalisée à l'aide d'un élastomère 3 qui est inséré dans un espace de montage 4. L'espace de montage 4 est délimité d'un côté par la surface intérieure 6 du corps for mant logement 2. De l'autre côté, l'espace de montage est délimité par la surface extérieure 5 d'une bague 9 montée sur la bague de roulement extérieure 1. FIG. 1 shows a bearing, including the outer ring 1, and is connected to a housing body 2. The connection is made using an elastomer 3 which is inserted into a mounting space 4. The mounting space 4 is delimited on one side by the inner surface 6 of the body for mantle housing 2. On the other side, the mounting space is delimited by the outer surface 5 of a ring 9 mounted on the outer race 1 .

Il est naturellement possible de supprimer la bague 9 et d'appliquer l'élastomère 3 directement sur la surface extérieure de la bague de roulement extérieure 1. It is naturally possible to remove the ring 9 and to apply the elastomer 3 directly to the outer surface of the outer race 1.

Afin d'augmenter la résistance vis-à-vis des efforts axiaux entre le roulement et le corps formant logement, il est prévu d'aménager dans le corps formant logement 2 et dans la bague 9 des trous 7, dans lesquels l'élastomère 3 soumis à une pression peut pénétrer, comme le montre clai rement la figure. Cette pénétration de l'élastomère dans les trous aug mente considérablement la résistance au glissement axial. La liaison entre le premier élément de machine 1 et le second élément de machine 2 est ainsi améliorée. In order to increase the resistance with respect to the axial forces between the bearing and the housing body, provision is made in the housing body 2 and in the ring 9 for holes 7 in which the elastomer 3 pressure can penetrate, as clearly shown in the figure. This penetration of the elastomer into the holes considerably increases axial slip resistance. The connection between the first machine element 1 and the second machine element 2 is thus improved.

La figure 2 représente une variante d'agencement. Sur cette figure, le corps formant logement 2 et la bague 9 présentent respective ment sur leur surface intérieure 6 et leur surface extérieure<B>5</B> des surélévations 8 en forme de boutons. Avec celles-ci, on obtient le même effet que celui décrit en relation avec la figure l: l'élastomère 3 rencontre lors d'une tentative de déplacement axial du roulement par rapport au corps formant logement 2 une résistance accrue qui est due à la présence des boutons. Figure 2 shows an alternative arrangement. In this figure, the housing body 2 and the ring 9 respectively have on their inner surface 6 and their outer surface <B> 5 </ B> elevations 8 in the form of buttons. With these, the same effect as that described with reference to FIG. 1 is obtained: the elastomer 3 encounters, during an attempt at axial displacement of the bearing with respect to the housing body 2, an increased resistance which is due to the presence of buttons.

Comme le montre la figure 3, les évidements 7 et les surélévations 8 peuvent être disposés de manière équidistantes sur le pourtour des surfaces concernées de la bague de roulement extérieure 1 et de la bague 9 d'une part et du corps formant logement 2 d'autre part. Il est encore possible de disposer les trous 7 et les boutons 8 de manière décalée.As shown in FIG. 3, the recesses 7 and the elevations 8 may be arranged equidistantly around the perimeter of the surfaces concerned of the outer race 1 and the ring 9 on the one hand and the housing body 2 on the other hand. somewhere else. It is still possible to arrange the holes 7 and the buttons 8 in a staggered manner.

Toutes ces dispositions permettent d'augmenter encore la stabilité de la liaison entre le premier élément de machine 1 et le second élément de machine 2. All these arrangements make it possible to further increase the stability of the connection between the first machine element 1 and the second machine element 2.
