Description
Douille de roulement ou palier gour tourillon de joint de cardan.Rolling bearing or bearing with cardan joint trunnion.
La présente invention concerne une douille de roulement ou palier pour tourillon de joint de cardan, qui prend appui par des moyens de retenue dans l'alésage de réception de la machoire du joint de cardan, cette douille étant constituée par une tôle à paroi mince munie d'un fond qui présente, en son centre, une surface de portée ou de butée faisant saillie en direction de la face terminale du tourillon de joint de cardan. The present invention relates to a bearing sleeve or bearing for a universal joint joint, which bears by means of retaining means in the receiving bore of the jaw of the universal joint, this sleeve being constituted by a thin-walled sheet provided a bottom which has, in its center, a bearing or abutment surface projecting towards the end face of the cardan joint journal.
Une douille de roulement ou palier de ce type est déjà connue (demande de brevet allemand 21 22 575). Afin de permettre le fonctionnement parfait d'un joint de cardan, il faut obtenir une application sans jeu du roulement contre le tourillon du joint de cardan. Pour pouvoir compenser en service les jeux pouvant apparaître dans le sens axial entre le roulement ou palier et le tourillon, les roulements ou paliers doivent être appliqués autant que possible sous une contrainte préalable contre le tourillon du joint de cardan. A bearing bush or bearing of this type is already known (German patent application 21 22 575). In order to allow perfect functioning of a universal joint, it is necessary to obtain an application without play of the bearing against the trunnion of the universal joint. In order to be able to compensate in play for the play that may appear in the axial direction between the bearing or bearing and the journal, the bearings or bearings must be applied as much as possible under prior stress against the journal of the universal joint.
Dans la douille de roulement ou palier décrite dans la demande de brevet allemand 21 22 575,,on obtient, sous l'action de la tôle à paroi mince devant être montée avec une certaine force d'application, une caractéristique d'élasticité relativement plate du fond. Cette caractéristique d'élasticité, combinée avec la surface de portée en saillie prévue au centre du fond de la douille et orientée vers le tourillon, satisfait à la condition d'application sans jeu et fournit simultanément l'avantage d'un faible moment de friction. La force d'application crée toutefois un bombement de la surface de portée et ainsi la surface terminale du tourillon du joint de cardan ne vient s'appliquer tout d'abord que sur le bord extérieur de celle-ci.C'est seulement lorsque l'arête créée sur la surface de portée par le bombement a été éliminée par frottement que la totalité de la surface de portée s'applique à plat contre la face terminale du tourillon du joint de cardan. Il en résulte toutefois une force d'application réduite. Dans les conditions les plus défavorables, cette force peut devenir si faible que la contrainte préalable tend vers zéro. Ainsi, des jeux axiaux peuvent apparaître en service entre le roulement ou palier et le tour ilion. In the rolling bushing or bearing described in German patent application 21 22 575, a relatively flat elasticity characteristic is obtained under the action of the thin-walled sheet to be mounted with a certain application force. the bottom. This elasticity characteristic, combined with the projecting bearing surface provided in the center of the bottom of the sleeve and oriented towards the pin, satisfies the condition of application without play and simultaneously provides the advantage of a low friction moment. . The application force, however, creates a bulging of the bearing surface and thus the end surface of the universal joint trunnion is first applied only on the outer edge thereof. It is only when the he edge created on the bearing surface by the bulge has been removed by friction as the entire bearing surface is applied flat against the end face of the cardan joint journal. However, this results in a reduced application force. In the most unfavorable conditions, this force can become so weak that the preliminary stress tends towards zero. Thus, axial clearances can appear in service between the bearing or bearing and the ilion turn.
Le but de l'invention est, tout en conservant les avantages connus, d'éliminer les inconvénients des conditions de portée variables et les conséquences qui en résultent, de manière simple et représentant un progrès. The object of the invention is, while retaining the known advantages, to eliminate the drawbacks of the conditions of variable scope and the consequences which result therefrom, in a simple manner and representing progress.
Suivant l'invention, on parvient à ce résultat par le fait que la surface de portée présente, dans sa condition initiale, une convexité en direction de l'axe du tourillon de joint de cardan, qui est déformée dans la condition de montage, sous l'effet d'une force agissant entre le tourillon de joint de cardan et la surface de portée, pour fournir une surface en principe plane. According to the invention, this is achieved by the fact that the bearing surface has, in its initial condition, a convexity in the direction of the axis of the cardan joint journal, which is deformed in the mounting condition, under the effect of a force acting between the universal joint pin and the bearing surface, to provide a generally flat surface.
La convexité de la surface de portée qui est présente dans la condition initiale et qui est soumise dans la condition de montage i une force d'application, en subissant ainsi une déformation pour prendre une condition en principe plane, exerce un effet avantageux sur la -longé- vitb ou durée de service du joint de cardan. Ce résultat repose sur le fait que la surface de portée a la même dimension depuis le début et sur les avantages qui en résultent du fait du caractère invariable de la précontrainte et du rayon de friction, ainsi que du moment de friction, étant donné que depuis le début cette surface de portée déterminée est disponible pour sa coopération avec la face terminale du tourillon du joint de cardan. The convexity of the bearing surface which is present in the initial condition and which is subjected in the mounting condition to an application force, thereby undergoing a deformation to assume a generally flat condition, has an advantageous effect on the - longevity or service life of the universal joint. This result is based on the fact that the bearing surface has the same dimension from the start and on the advantages which result therefrom due to the invariable nature of the preload and the radius of friction, as well as the moment of friction, since since at the start, this determined surface area is available for its cooperation with the end face of the universal joint trunnion.
Suivant des réalisations avantageuses de l'invention, on peut prévoir dans la surface de portée des profilages allant d'au moins une creusure jusqu'S un réseau de creusures en forme de gaufrette, réparties sur la surface de portée pour la réception de lubrifiant. Ces dispositions ménagent avec certitude une certaine réserve de lubrifiant sur la surface de portée et rendent ainsi inutile un entretien de celle-ci en ce qui concerne son graissage. According to advantageous embodiments of the invention, profiling can be provided in the bearing surface going from at least one recess to a network of wafer-shaped recesses distributed over the bearing surface for receiving lubricant. These provisions provide with certainty a certain reserve of lubricant on the bearing surface and thus make it unnecessary to maintain it as regards its lubrication.
La description qui va suivre, faite en regard des dessins annexés, montrant des modes de réalisation de l'invention dans la condition de départ et dans la condition de montage, permettra de mieux comprendre cette dernière. The description which follows, made with reference to the appended drawings, showing embodiments of the invention in the starting condition and in the mounting condition, will allow a better understanding of the latter.
La Fig. 1 est une vue en coupe longitudinale d'une douille de roulement en condition montée. Fig. 1 is a view in longitudinal section of a bearing sleeve in mounted condition.
La Fig. 2 est une vue en coupe partielle à travers une douille de roulement qui se trouve dans sa condition de départ ou condition initiale, à plus grande échelle que sur la Fig. i. Fig. 2 is a view in partial section through a rolling bushing which is in its starting condition or initial condition, on a larger scale than in FIG. i.
La Fig. 3 montre une réalisation possible de la surface de portée, en regardant selon la flèche III sur la
Fig. 1.Fig. 3 shows a possible embodiment of the bearing surface, looking according to arrow III on the
Fig. 1.
On a représenté sur la Fig. 1 une partie d'un joint de cardan avec la douille de roulement suivant l'invention en condition montée. La mSchoire 2 du joint de cardan présente un alésage 3 dans lequel la douille de roulement 1 prend appui par l'intermédiaire d'une bague de retenue 4. Le tourillon 5 du joint de cardan est monté dans la douille de roulement 1 avec interposition d'aiguilles de roulement 6. La face terminale ou face d'extrémité 7 du tourillon de joint de cardan 5 s'applique, dans la condition de montage représentée ici, contre la surface de portée en principe plane 8 du fond 9 de la douille.Pour assurer une protection contre la pénétration de particules de saleté, il est prévu sur le côté ouvert de la douille de roulement 1 un rebord radial 10 contre lequel prend appui un joint d'étanchéité élastique i lèvre 11. There is shown in FIG. 1 part of a universal joint with the bearing sleeve according to the invention in mounted condition. The mSchoire 2 of the universal joint has a bore 3 in which the bearing bush 1 is supported by means of a retaining ring 4. The pin 5 of the universal joint is mounted in the bearing bush 1 with interposition d 'bearing needles 6. The end face or end face 7 of the cardan joint pin 5 is applied, in the mounting condition shown here, against the generally flat bearing surface 8 of the bottom 9 of the sleeve. To provide protection against the ingress of dirt particles, a radial rim 10 is provided on the open side of the rolling sleeve 1 against which an elastic seal i lip 11 is supported.
On a représenté sur la Fig. 2 une douille de roulement 1 qui se trouve encore dans la condition de départ, peu avant la fin du montage. On voit nettement sur cette
Figure la convexité de la surface de portée 8. L'une des nombreuses possibilités pour la réception du lubrifiant est également représentée par la creusure 12.There is shown in FIG. 2 a bearing sleeve 1 which is still in the initial condition, shortly before the end of the assembly. We can clearly see on this
The convexity of the bearing surface 8 is shown. One of the numerous possibilities for receiving the lubricant is also represented by the recess 12.
La Fig. 3 montre, en regardant suivant la flèche
III en Fig. 1 une autre réalisation possible de la surface de portée 8, qui est munie d'un réseau en forme de gaufrette constitué de dépressions ou creusures 13.Fig. 3 shows, looking along the arrow
III in Fig. 1 another possible embodiment of the bearing surface 8, which is provided with a wafer-shaped network consisting of depressions or recesses 13.
L'invention n'est pas limitée toutefois aux exemples de réalisation représentés. Une douille de roulement de ce type peut se présenter fondamentalement sous la forme d'une douille de palier lisse. La conformation de la convexité et des moyens de réception du lubrifiant sur la surface de portée, ainsi que le type de moyens de retenue pour la douille de roulement ou palier dans l'alésage de la mâchoire dépendent entre autres également de l'économie du procédé de fabrication et de montage, et ils peuvent en conséquence se présenter sous un aspect différent. Les dessins ne peuvent représenter que quelques possibilités pour la réalisation constructive de l'invention. The invention is not limited however to the embodiments shown. A bearing sleeve of this type can be basically in the form of a plain bearing sleeve. The conformation of the convexity and of the means for receiving the lubricant on the bearing surface, as well as the type of retaining means for the rolling sleeve or bearing in the bore of the jaw also depend inter alia on the economy of the process. manufacturing and mounting, and they may therefore appear in a different aspect. The drawings can only represent a few possibilities for the constructive realization of the invention.
