Description

CAGE DE RETENUE DE ROULEAUX POUR ROULEMENTS
L'invention concerne les cages de retenue de rouleaux pour roule ment s du type comportant une partie extérieure pourvue de fenêtres de maintien des rouleaux et un bord latéral orienté radialement.ROLL RETAINER CAGE FOR BEARINGS
The invention relates to roll retaining cages of the rolling type of the type comprising an outer part provided with windows for retaining the rollers and a radially oriented side edge.

La publication DE-A- 1 775 245 décrit un exemple de réalisation d'une telle cage.Publication DE-A- 1 775 245 describes an example of an embodiment of such a cage.

Dans les roulements à rouleaux utilisant des cages dont la partie extérieure est en forme de tronc de cône avec un flasque latéral, les rouleaux sont usuellement en appui latéral sur un rebord rapporté ou formé dans la matière constitutive de la bague du roulement. Dans les roulements de ce type décrit par le brevet FR-A1 539 010, le lubrifiant de graissage circule, sous l'effet de la force centrifuge, communiquée au lubrifiant par suite du mouvement relatif des surfaces en contact avec les rouleaux, du petit au grand diamètre de ces surfaces. I1 en résulte que la lubrification du contact des rouleaux avec le rebord de la bague de roulement peut devenir défectueuse conduisant à des grippages et une usure prématurée du roulement.In roller bearings using cages whose outer part is in the shape of a truncated cone with a lateral flange, the rollers are usually in lateral abutment on a flange added or formed in the material constituting the bearing ring. In bearings of this type described by patent FR-A1 539 010, the lubricating lubricant circulates, under the effect of centrifugal force, communicated to the lubricant as a result of the relative movement of the surfaces in contact with the rollers, from small to large diameter of these surfaces. As a result, the lubrication of the contact of the rollers with the edge of the bearing ring can become defective, leading to seizures and premature wear of the bearing.

Selon l'invention, le problème est résolu par le fait que le grand diamètre de la partie extérieure de la cage porte un déflecteur orienté radialement vers le rebord qui force le flux de lubrifiant à se rapprocher du contact des rouleaux avec le rebord.According to the invention, the problem is solved by the fact that the large diameter of the external part of the cage carries a deflector oriented radially towards the rim which forces the flow of lubricant to approach the contact of the rollers with the rim.

Dans le roulement comportant une telle cage, la circulation du lubrifiant peut être ajustée par un choix judicieux des jeux radiaux du flasque et du déflecteur avec les éléments porteurs des pistes de roulement.In the bearing comprising such a cage, the circulation of the lubricant can be adjusted by a judicious choice of the radial clearances of the flange and of the deflector with the bearing elements of the rolling tracks.

Pour faire mieux comprendre l'objet de l'invention, on va en décrire à titre d'exemple non limitatif des modes de réalisation représentés au dessin annexé sur lequel - la figure 1 est une demi-coupe axiale d'un roulement à une ran
gée de rouleaux coniques placés dans une cage conventionnelle ; - la figure 2 est une demi-coupe axiale du roulement représenté à
la figure 1 avec une cage modifiée conformément à l'invention ; - les figures 3 et 4 représentent une demi-coupe axiale du roule
ment représenté à la figure 1 avec une cage selon deux variantes
de réalisation de l'invention.To better understand the object of the invention, we will describe by way of nonlimiting example of the embodiments shown in the accompanying drawing in which - Figure 1 is an axial half-section of a bearing with a ran
conical rollers placed in a conventional cage; - Figure 2 is an axial half-section of the bearing shown at
Figure 1 with a cage modified according to the invention; - Figures 3 and 4 show an axial half-section of the wheel
shown in Figure 1 with a cage in two variants
for carrying out the invention.

La figure 1 se rapporte à un roulement à rouleaux coniques 1 disposés entre les pistes de roulement 2, 3 portées par une bague extérieure 4 et une bague intérieure 5. La bague extérieure 4 ne comporte pas de rebord, alors que la bague intérieure 5 comporte un petit et un grand rebord 6, 7 qui limitent latéralement le petit et le grand diamètre de la piste 3.Figure 1 relates to a tapered roller bearing 1 disposed between the raceways 2, 3 carried by an outer ring 4 and an inner ring 5. The outer ring 4 has no flange, while the inner ring 5 has a small and a large ledge 6, 7 which laterally limit the small and the large diameter of the track 3.

La cage 8 en tôle ou en matière plastique ayant une section en L comporte des fenêtres 9 de maintien des rouleaux 1 dans sa partie extérieure tronconique 10 qui est disposée radialement à 1 'exté- rieur du cône médian 11 de ces rouleaux et un bord latéral rabattu 13.The cage 8 made of sheet metal or plastic having an L-shaped section has windows 9 for holding the rollers 1 in its frustoconical outer part 10 which is arranged radially outside the median cone 11 of these rollers and a lateral edge folded down 13.

Selon la figure 2, le grand diamètre de la partie extérieure tronconique 10 de la cage 8 porte un déflecteur 14 orienté radialement vers le rebord 7. Le flux de graissage F dans le roulement peut être ajusté par le choix du jeu "jl" entre le bord latéral 13 et le rebord 6 et par celui du jeu "j2" entre le déflecteur 14 et le rebord 7. Le déflecteur 14 est formé dans la matière constitutive de la cage qui peut être fabriquée par emboutissage de tôle ou injection de matière plastique.According to FIG. 2, the large diameter of the frustoconical outer part 10 of the cage 8 carries a deflector 14 oriented radially towards the flange 7. The lubrication flow F in the bearing can be adjusted by choosing the clearance "jl" between the lateral edge 13 and the rim 6 and by that of the clearance "j2" between the deflector 14 and the rim 7. The deflector 14 is formed in the material constituting the cage which can be produced by stamping of sheet metal or injection of plastic material.

Selon la figure 3, le déflecteur 15 est constitué par un anneau en tôle rapporté et fixé par tout procédé connu (collage, soudage, rivetage, roulage) au bord extérieur de la cage. According to Figure 3, the deflector 15 is constituted by a sheet metal ring attached and fixed by any known method (bonding, welding, riveting, rolling) to the outer edge of the cage.

Selon la figure 4, le déflecteur 16 est constitué par un anneau en matière plastique rapporté sur la partie tronconique 10 de la cage, par tout procédé applicable à une telle variante de réalisation tel l'encastrement ou collage. According to Figure 4, the deflector 16 is constituted by a plastic ring attached to the frustoconical part 10 of the cage, by any method applicable to such an alternative embodiment such as embedding or bonding.

Il y a toutefois lieu de remarquer que la cage 7 s'applique indifféremment aux rouleaux cylindriques, coniques ou sphériques.However, it should be noted that the cage 7 applies equally to cylindrical, conical or spherical rollers.

Bien entendu, l'invention n'est nullement limitée à l'exemple de roulement décrit. Elle s'applique également aux roulements dont la bague intérieure ne comporte pas de rebord et dont la bague extérieure comporte au moins un rebord qui limite latéralement le grand diamètre de la piste de roulement, la cage présentant alors sa partie tronconique disposée radialement à l'intérieur du cône médian des rouleaux. Of course, the invention is in no way limited to the example of rolling described. It also applies to bearings whose inner ring does not have a rim and whose outer ring has at least one rim which laterally limits the large diameter of the race track, the cage then having its frustoconical part disposed radially to the inside of the middle cone of the rollers.
