Description
La présente invention porte sur un roulementThe present invention relates to a bearing
à billes à contact oblique, à disposition en 0, c'est- angular contact ball bearings, available in 0, that is
à-dire que les cônes qui contiennent les lignes de con- to say that the cones that contain the lines of con-
tact de chaque roulement avec les bagues correspondantes sont dirigés en sens inverse et se rencontrent à l'exté- tact of each bearing with the corresponding rings are directed in the opposite direction and meet on the outside.
rieur du roulement par rapport à l'axe. the bearing relative to the axis.
Plus précisément, l'invention porte sur un roulement à deux rangées de billes à contact oblique à disposition en 0, comportant une bague extérieure d'une seule pièce, un ensemble de bague intérieur formé de deux bagues dont une seule présente une gorge intérieure, et une cage d'une seule pièce et pourvue d'une saillie radiale qui s'engage dans la gorge, la bague extérieure étant dépourvue d'épaulement du côté frontal au moins du côté de la bague intérieure sans gorge. Dans le cas o les bagues intérieures de ce roulement sont placées côte à côte, la bague intérieure sans gorge a aussi un épaulement sur le côté dirigé vers l'autre bague intérieure, et, dans le cas o les bagues intérieures sont emmanchées l'une sur l'autre, la bague intérieure à gorge est fixée avec ajustement More specifically, the invention relates to a two-row bearing of angular contact balls available at 0, comprising a one-piece outer ring, an inner ring assembly formed of two rings, one of which has an internal groove, and a cage in one piece and provided with a radial projection which engages in the groove, the outer ring being devoid of shoulder on the front side at least on the side of the inner ring without groove. In the case where the inner rings of this bearing are placed side by side, the inner ring without groove also has a shoulder on the side directed towards the other inner ring, and, in the case where the inner rings are fitted one on the other, the inner grooved ring is fixed with adjustment
serré sur une rallonge de l'autre bague intérieure. tight on an extension of the other inner ring.
La cage à fenêtres d'un roulement de ce type remplit convenablement le rôle qui lui est demandé, mais on peut l'améliorer en ce qui concerne l'encombrement The window casing of a bearing of this type satisfactorily fulfills the role which is required of it, but it can be improved with regard to the space requirement
et le montage.and editing.
C'est pourquoi l'invention a pour objet de réaliser un roulement à deux rangées de billes et à contact oblique tel que mentionné ci-dessus, mais qui soit d'encombrement plus réduit et de montage plus simple. A cet effet la cage est réalisée sous forme de cage à peigne avec des parties saisissant au moins par derrière dans le sens axial les billes de la bague This is why the object of the invention is to provide a two row angular contact ball bearing as mentioned above, but which is smaller in size and easier to mount. For this purpose the cage is made in the form of a comb cage with parts gripping at least from behind in the axial direction the balls of the ring.
intérieure sans gorge.inner without throat.
Comme la cage est constituée, du c8té de la bague intérieure sans gorge en forme de peigne et avec des parties saisissant les billes par derrière, d'une part ces billes ne peuvent alors sortir de la bague extérieure, même s'il n'existe pas d'épaulement de ce c8té; elles sont en effet maintenues par la cage et par la deuxième rangée de billeso D'autre part, la partie de peigne peut être fabriquée avec seulement un noyau de moulage coulissant axialemento En outre, elle n'exige pas d'espace supplémentaire dans le sens axial, de sorte que le joint d'étanchéité généralement nécessaire peut être placé au plus près de la rangée de billes, ce qui fait que l'encombrement et le poids du roulement peuvent être très réduits ce qui est souvent souhaitableo Dans le cas o les bagues de roulement sont disposées l'une contre l'autre, la bague intérieure sans gorge est maintenue contre les pièces susmentionnées grâce au fait qu'elle présente un épaulement en direction As the cage is formed, the side of the inner ring without comb-shaped groove and with parts gripping the balls from behind, on the one hand these balls can not then out of the outer ring, even if there is no shoulder of this side; they are in fact held by the cage and by the second row of balls. On the other hand, the comb part can be made with only an axially sliding casting core. In addition, it does not require additional space in the direction axial, so that the generally required gasket can be placed closer to the row of balls, so that the size and weight of the bearing can be very reduced which is often desirableo In the case where the rolling rings are arranged against each other, the inner ring without groove is held against the aforementioned parts by virtue of the fact that it has a shoulder in the direction
de l'autre bague intérieure.on the other inner ring.
Dans le cas o les bagues intérieures sont emmanchées l'une sur l'autre, la bague intérieure avec gorge est montée sur un prolongement de l'autre bague intérieure avec ajustement serré. De ce fait on n'a pas besoin d'avoir d'épaulement intérieur sur la bague intérieure. Avec ces dispositions on obtient une unité structurale pour toutes les parties du roulement. La In the case where the inner rings are fitted on one another, the inner ring with groove is mounted on an extension of the other inner ring with a tight fit. As a result, there is no need to have an inner shoulder on the inner ring. With these provisions we obtain a structural unit for all parts of the bearing. The

Selon une modalité supplémentaire, la cage peut posséder chaque fois, dans sa pièce annulaire, des évidements dans la région des poches. De cette façon l'élasticité, avantageuse lors du montage de la cage est According to an additional embodiment, the cage may have each time, in its annular part, recesses in the region of the pockets. In this way the elasticity, advantageous during the assembly of the cage is

L'invention sera exposée plus en détail avec référence à deux figures, à savoir: la figure 1 montre une coupe transversale partielle d'une unité structurale de roulement selon l'invention; The invention will be explained in more detail with reference to two figures, namely: FIG. 1 shows a partial cross-section of a structural bearing unit according to the invention;
la figure 2 est une variante de la figure 1. Figure 2 is a variant of Figure 1.
Le roulement à deux rangées de billes à contact oblique, à disposition en O selon la figure 1 est constitué d'une bague extérieure 1 d'une pièce, de deux bagues intérieures 2 et 3, d'une cage 4 et de deux rangées de billes 5 et 6. La première rangée de The double-row angular contact ball bearing, arranged in O according to FIG. 1 consists of an outer ring 1 in one piece, two inner rings 2 and 3, a cage 4 and two rows of balls 5 and 6. The first row of

face frontale 3' jusque dans la région de la rangée de billes 5. Par suite, on peut prévoir sans difficulté front face 3 'to the region of the row of balls 5. As a result, one can predict without difficulty

Afin que la rangée de billes 5 soit It is thus possible to obtain a structural unit constituted by the outer ring 1, the cage 4, the row of balls 6 and the inner ring 3. In order for the row of balls 5 to be a radial projection 8 of the cage 4.

billes 5, la forme d'un peigne 9, comportant des par- 5, the shape of a comb 9, comprising parts
ties 9' qui enserrent les billes de cette rangée. En outre, la partie annulaire 4' de la cage 4 présente des évidements 4" qui rendent la cage 4 élastique et forment des chambres pour des réserves de graisse. La bague intérieure étroite 2 présente seulement un petit 9 'enclosing the balls of this row. In addition, the annular portion 4 'of the cage 4 has recesses 4 "which make the cage 4 elastic and form chambers for fat reserves.The narrow inner ring 2 has only a small
épaulement 2' grâce auquel elle est immobilisée axiale- shoulder 2 'with which it is immobilized axially-
ment. L'unité structurale de palier 2, constituée par toutes les pièces susmentionnées, peut être ainsi fabriquée et assemblée de façon simple par le fabricant du rculement. Il est alors facile de la manier et de la monter. Dans le cas de paliers comportant un épaulement 1' du côté frontal sur la bague extérieure 1 dans la région de la rangée de billes 6, il est utile de pourvoir la cage 4 d'une partie de barrettes 11 se prolongeant radialement. Lors du montage les billes de la rangée 6 peuvent alors s'écharper radialerent vers l'intérieur lorsqu'elles sont Poussées contre l'épaulement extérieur is lying. The bearing structural unit 2, consisting of all the aforementioned parts, can thus be manufactured and assembled in a simple manner by the manufacturer of the transition. It is then easy to handle and mount. In the case of bearings having a shoulder 1 'of the front side on the outer ring 1 in the region of the row of balls 6, it is useful to provide the cage 4 of a portion of bars 11 extending radially. During assembly, the balls of the row 6 can then be discharged radially inwards when they are pushed against the outer shoulder.

Sur la figure 2 on voit un palier de roue de In Figure 2 we see a wheel bearing of
camion qui est très semblable à celui selon la figure 1. truck that is very similar to the one in Figure 1.
La différence principale se limite à la bague intérieure sans gorge 12. Celle-ci comporte d'un coté un prolongement The main difference is limited to the inner ring without groove 12. The latter has on one side an extension
12' sur lequel l'autre bague intérieure 3 est enfilé. 12 'on which the other inner ring 3 is threaded.
Une bride de fixation 12" est intégrée de l'autre côté. A 12 "mounting flange is integrated on the other side.
L'unité structurale comportant la bague extérieure 1, les deux rangées de rouleaux 5 et 6, la cage 4 et la bague intérieure 3 est obtenue par les moyens déjà décrits pour la figure 1. Au lieu du petit épaulement 2' selon la figure 1, qui serait également possible ici, il est prévu sur la bague intérieure 12 The structural unit comprising the outer ring 1, the two rows of rollers 5 and 6, the cage 4 and the inner ring 3 is obtained by the means already described for FIG. 1. Instead of the small shoulder 2 'according to FIG. , which would also be possible here, it is provided on the inner ring 12
un espace libre 13, ceci en particulier pour des rai- a free space 13, this in particular for reasons
sons de montage. En effet, il est judicieux dans bien des cas de fabriquer séparément la bague intérieure 12 avec la bride et d'assembler toute l'unité seulement lors du montage dans la machine. Dans de tels cas l'espace libre 13 permet l'assemblage de la bague intérieure 12 avec les autres parties du palier. L'unité totale est obtenue ici grâce au fait que la bague intérieure 3 editing sounds. Indeed, it is advisable in many cases to separately manufacture the inner ring 12 with the flange and assemble the entire unit only during assembly in the machine. In such cases the free space 13 allows the assembly of the inner ring 12 with the other parts of the bearing. The total unit is obtained here thanks to the fact that the inner ring 3
est disposée avec ajustement serré sur le prolongement 12'. is arranged with a tight fit on the extension 12 '.
