Abstract

The mounting insert for a roller bearing has an axially split ring (8) with a non-planar outer contour which fits between the bearing outer race (7) and the support (2). The ring can have lips to retain the bearing. The ring is mounted within an outer elastomeric ring formed between the ring and support by vulcanization.

Description

<B>Liaison entre un premier élément de machine</B> et un second élément de machine, en particulier entre une <B>bague de palier et un logement.</B> L'invention concerne liaison d'une bague de palier, en particulier une bague de roulement extérieure avec un corps formant logement comprenant - une bague de palier avec au moins une surface orientée radialement présentant un contour non plan ; - un corps formant logement avec une surface orientée radialement, qui est disposée en vis-à-vis de la surface orientée radialement la bague de palier en ménageant un espace et présente un contour adapté dans une large mesure au contour non plan de la bague de palier; - un élément en élastomère qui est vulcanisé ou inséré à force dans l'espace formé entre la surface de la bague de palier et la surface du corps formant logement. <B> Link between a first machine element </ B> and a second machine element, in particular between a <B> bearing bushing and a housing. </ B> The invention relates to the connection of a bearing bushing , in particular an outer race with a housing body comprising - a bearing ring with at least one radially oriented surface having a non-planar contour; - a housing body with a radially oriented surface, which is arranged opposite the radially oriented surface of the bearing ring by providing a space and has a contour adapted to a large extent to the non-plane contour of the ring. bearing; an elastomeric element which is vulcanized or forced into the space formed between the surface of the bearing ring and the surface of the housing body.

Une liaison de ce type est connue par la demande de brevet DE 196 45 530 A1. Dans ce document, la bague extérieure d'un roulement est conformée de manière telle, que le contour extérieur de celle-ci a la forme d'un toit. Un corps formant logement partiellement tubulaire présente un contour intérieur adapté à cette forme de toit. Entre les deux éléments est inséré un élastomère, de telle sorte que la bague de roulement extérieure soit immobilisée dans le corps formant logement. A link of this type is known from patent application DE 196 45 530 A1. In this document, the outer ring of a bearing is shaped such that the outer contour thereof has the shape of a roof. A partially tubular housing body has an inner contour adapted to this roof shape. Between the two elements is inserted an elastomer, so that the outer race is immobilized in the housing body.

L'avantage d'une liaison de ce type est qu'elle peut être réalisée de manière relativement simple et assure une liaison suffisamment stable en fonctionnement entre les éléments de machine. Un inconvénient d'un tel mode de réalisation réside cependant dans le fait la fabrication de la bague extérieure de roulement impose l'utilisation de procédés de fabrication relativement chers, avec une dépense de matière relativement importante. Le contour non plan en forme toit implique l'utilisation d'une quantité de matériau plus grande que dans le cas d'une bague de roulement extérieure tradition nelle. D'autre part, le contour extérieur non plan de la bague de roulement entraine un travail de fabrication plus important. Un autre inconvénient réside dans le fait que pour mettre en oeuvre la liaison du type indiqué en introduction - avec le contour extérieur décrit la bague extérieure de roulement - il est nécessaire d'utiliser des roule ments spéciaux - à savoir des roulements dont la bague extérieure présente le contour extérieur mentionné. The advantage of a connection of this type is that it can be performed relatively simply and ensures a sufficiently stable connection in operation between the machine elements. A disadvantage of such an embodiment however lies in the fact that the manufacture of the outer bearing ring requires the use of relatively expensive manufacturing processes, with a relatively high material expenditure. The non-planar contour in roof form involves the use of a larger amount of material than in the case of a conventional outer race. On the other hand, the non-plane outer contour of the rolling ring leads to a larger manufacturing work. Another disadvantage lies in the fact that to implement the connection of the type indicated in the introduction - with the outer contour describes the outer race of the bearing - it is necessary to use special bearings - namely bearings whose outer ring presents the outer contour mentioned.

L'invention a pour objectif d'indiquer une liaison du type présenté en introduction entre un palier et un corps formant logement qui permettent d'éviter les inconvénients mentionnés plus haut. Elle doit également permettre d'utiliser des roulements ou des paliers lisses standards pour réaliser la liaison indiquée. The object of the invention is to indicate a connection of the type presented in the introduction between a bearing and a housing body which make it possible to avoid the disadvantages mentioned above. It must also allow the use of standard bearings or plain bearings to achieve the indicated connection.

Cet objectif est atteint conformément à l'invention par fait que la bague de palier comporte un corps de base qui est lié à une - gue intermédiaire, la bague intermédiaire présentant sur une surface orientée radialement le contour nom plan Ki. This object is achieved in accordance with the invention by the fact that the bearing ring comprises a base body which is connected to an intermediate gue, the intermediate ring having on a radially oriented surface the outline plane outline Ki.

Selon l'invention, il est prévu à la différence de l'état connu de la technique, d'utiliser un palier comportant une bague extérieure cylindrique sur laquelle est montée une bague qui forme le contour non plan. La bague extérieure munie de ladite bague est alors utilisée de la manière connue en soi pour réaliser la liaison avec le corps formant logement. According to the invention, it is provided unlike the state of the art to use a bearing having a cylindrical outer ring on which is mounted a ring which forms the non-planar contour. The outer ring provided with said ring is then used in the manner known per se to make the connection with the housing body.

De préférence la bague et liée par complémentarité de forme au corps de base. De manière particulièrement avantageuse, la bague est fendue axialement en au moins un point. Grâce à cet agencement particulier, la bague peut être ouverte élastiquement à des fins montage sur le corps de base et peut glisser sur ledit corps de base lindrique. Du fait de son élasticité, la bague se resserre ensuite et for me une liaison ferme avec le corps de base. Preferably the ring and formally complementary to the base body. In a particularly advantageous manner, the ring is slotted axially in at least one point. With this particular arrangement, the ring can be resiliently opened for mounting on the base body and can slide on said lindrical base body. Because of its elasticity, the ring then tightens and for me a firm connection with the basic body.

Le corps de base de la bague de palier présente de préférence un contour extérieur et/ou intérieur essentiellement cylindrique. The base body of the bearing ring preferably has a substantially cylindrical outer and / or inner contour.

Un exemple de réalisation de l'invention est représenté sur les dessins. An exemplary embodiment of the invention is shown in the drawings.

La figure 1 montre de manière schématique une vue en coupe de la liaison entre une bague de roulement et un corps formant logement, La figure 2 montre la manière dont l'élastomère est inséré entre la bague de roulement et le corps formant logement. Figure 1 schematically shows a sectional view of the connection between a bearing ring and a housing body. Figure 2 shows the manner in which the elastomer is inserted between the bearing ring and the housing body.

La figure 1 montre une bague de palier extérieure qui fait partie d'un palier à roulement 9. Figure 1 shows an outer bearing ring which is part of a rolling bearing 9.

La bague de roulement 1 et doit être liée à un corps formant logement 2, un élastomère 5 étant inséré entre la bague de roulement 1 et le corps formant logement 2 aux fins d'obtenir un comportement élastique entre le corps formant logement 2 et le palier à roulement 9. The race 1 and must be connected to a housing body 2, an elastomer 5 being inserted between the race 1 and the housing body 2 for the purpose of obtaining an elastic behavior between the housing body 2 and the bearing rolling 9.

cet effet, la bague de roulement 1 présente un corps de base 7 sur lequel est emmanchée une bague 8 fendue. Le corps de base 7 de la bague de roulement correspond à palier à roulement courant, à contour extérieur cylindrique. La bague de roulement, dans une certaine mesure, est fabriquée de manière conventionnelle. Afin de donner un contour non plan K1 à la bague de roulement, bague 8 emmanchée sur le corps de base présente, en section transversale, un contour adapté. Sa surface 3 orientée radialement est disposée en vis- à-vis d'une surface 4 associée également orientée radialement du corps formant logement. La distance entre les deux surfaces K, et en vis- à-vis est désignée "a" sur la figure 2. this effect, the bearing ring 1 has a base body 7 on which is fitted a split ring 8. The base body 7 of the bearing ring corresponds to a running rolling bearing with a cylindrical outer contour. The bearing ring, to some extent, is manufactured in a conventional manner. In order to give a non-planar contour K1 to the bearing ring, ring 8 fitted on the base body has, in cross section, a suitable contour. Its radially oriented surface 3 is disposed facing an associated radially oriented surface 4 of the housing body. The distance between the two surfaces K, and vis-à-vis is designated "a" in Figure 2.

L'élastomère 5 est inséré à force dans l'espace 6 formé entre le corps formant logement 2 et la bague de roulement 1, de manière à obtenir une liaison stable et malgré tout élastique. Comme variante, l'élastomère peut être vulcanisé sur les éléments. The elastomer 5 is forced into the space 6 formed between the housing body 2 and the race 1, so as to obtain a stable connection and still elastic. Alternatively, the elastomer can be vulcanized onto the elements.

Comme le montre plus particulièrement la figure 2, l'élastomère 5 est inséré dans l'espace 6 au moyen d'un dispositif spécial. On place la bague en élastomère 5 dans le dispositif, la bague présentant à l'état non comprimé une épaisseur initiale a0. En appli quant une force F en direction de la partie représentée sur la figure 2, on chasse l'élastomère 5 dans l'espace 6. Ce faisant l'épaisseur de la bague est réduite à la valeur a, et la bague est maintenue dans cet état entre le corps formant logement 2 et la bague de roulement 1.As shown more particularly in Figure 2, the elastomer 5 is inserted into the space 6 by means of a special device. The elastomer ring 5 is placed in the device, the ring having in the uncompressed state an initial thickness a0. By applying a force F towards the part shown in FIG. 2, the elastomer 5 is driven into the space 6. In doing so, the thickness of the ring is reduced to the value a, and the ring is maintained in this state between the housing body 2 and the bearing ring 1.

La solution proposée par l'invention permet de réaliser la liaison connue de par l'état de la technique entre une bague de palier et un corps formant logement, de manière simple, cela même dans les cas où l'on utilise un palier conventionnel avec un contour extérieur cylindrique. Le corps de base 7 de la bague de roulement peut compor ter des encoches ou des surfaces d'appui pour la bague 8 expansible; ces dispositions représentent toutefois un travail très limité comparé à la solution connue par l'état de la technique. The solution proposed by the invention makes it possible to achieve the connection known from the state of the art between a bearing ring and a housing body, in a simple manner, even in cases where a conventional bearing is used with a cylindrical outer contour. The base body 7 of the bearing ring may have notches or bearing surfaces for the expandable ring 8; these provisions, however, represent a very limited work compared to the solution known from the state of the art.

Ainsi donc la liaison décrite peut être réalisée d'une manière simple et bon marché. Thus the link described can be achieved in a simple and inexpensive way.
