Description
La présente invention concerne un palier à rouleaux comportant une cage,The present invention relates to a roller bearing comprising a cage,
divisée transversalement à ladivided transversely to the
direction périphérique, pour des rouleaux. peripheral direction, for rollers.
Une telle cage subdivisée est connue par le modèle d'utilité allemand n 80 08271 et est montée dans une gorge de palier, par exemple d'un carter de transmission d'un appareil de levage, qui est limitée par des bagues pour le palier. Les segments de la cage connue sont maintenus par des crampons, qui sont pressés sur les traverses d'extrémité. L'inconvénient consiste dans la liaison qui ne résiste pas à la flexion des joints, du fait que les crampons se gauchissent, parce qu'ils ne peuvent transférer que de faibles moments de flexion. A Such a subdivided cage is known from the German Utility Model No. 80 08271 and is mounted in a bearing groove, for example a transmission housing of a hoist, which is limited by rings for the bearing. The segments of the known cage are held by crampons, which are pressed on the end rails. The disadvantage is the binding which does not withstand flexing of the joints, because the studs are warped, because they can only transfer small bending moments. AT
l'usage, la cage peut se déformer du fait de l'échauffe- use, the cage can become deformed due to warming

En conséquence, l'invention a pour objet de réaliser, de façon résistant à la flexion, un palier à rouleaux comportant une cage, divisée transversalement à la Accordingly, the object of the invention is to provide, in a bending-resistant manner, a roller bearing having a cage, divided transversely to the
direction périphérique, pour des rouleaux. peripheral direction, for rollers.
A cet effet, le palier à rouleaux comportant une cage divisée transversalement à la direction périphérique, qui présente, à son joint, des perçages longitudinaux et des broches coopérant avec ceux-ci, en particulier pour l'appui d'un tambour d'enroulement sur un carter de transmission, est remarquable, selon l'invention, en ce que la cage est guidée sur le carter de transmission entre des bagues en saillie, en ce que la cage est munie de renflements longitudinaux et de traverses, en ce que les perçages longitudinaux et les broches sont prévus dans les renflements longitudinaux latéraux, et en ce " que les broches sont constituées de douilles de serrage ou de goupilles à fente. Les broches sont pressées dans les perçages et communiquent à la cage divisée une grande résistance à la flexion en direction radiale à cause de la grande distance entre elles. Pour les plus grands paliers à rouleaux, par exemple d'un diamètre supérieur à 150 mm, la cage est formée de plusieurs segments, avantageusement de trois segments, et les traverses présentent des surfaces de guidage et For this purpose, the roller bearing comprises a cage divided transversely to the peripheral direction, which has, at its joint, longitudinal bores and pins cooperating therewith, in particular for the support of a winding drum. on a transmission casing, is remarkable, according to the invention, in that the cage is guided on the transmission casing between projecting rings, in that the cage is provided with longitudinal swellings and crosspieces, in that the Longitudinal holes and pins are provided in the lateral longitudinal bulges, and in that the pins consist of clamping sockets or slotted pins.The pins are pressed into the bores and communicate to the divided cage a great resistance to bending in radial direction because of the large distance between them.For larger roller bearings, for example with a diameter greater than 150 mm, the cage is formed of segments, advantageously of three segments, and the sleepers have guide surfaces and

ques, qui sont déjà montés dans les segments lors du prémontage. Les surfaces de guidage et les ergots à enclenchement ne s'étendent pas sur toute la longueur des rouleaux, mais seulement sur la zone d'extrémité de ceux-ci, pour ne pas racler le film de lubrifiant dans la zone de la pression la plus importante entre les rouleaux et la voie de roulement. Le rayon de courbure des surfaces de guidage avec les ergots à enclenchement est plus grand que le rayon des rouleaux et permet un déplacement des rouleaux en direction radiale du palier (provoqué par exemple par une excentricité de la surface de roulement which are already mounted in the segments during pre-assembly. Guide surfaces and snap-on lugs do not extend over the entire length of the rollers, but only on the end zone of the rollers, so as not to scrape the lubricant film into the area of the most between the rollers and the track. The radius of curvature of the guide surfaces with the latching lugs is greater than the radius of the rollers and allows a displacement of the rollers in the radial direction of the bearing (caused for example by an eccentricity of the running surface

forcé dans la zone du palier. Une bague du palier porte, avantageusement, un joint étanche adjacent au tambour d'enroulement. Quand le palier est monté dans un engin de levage, dans lequel il existe le risque d'une chute de la charge dans le cas d'un endommagement, le renforcement du carter au-dessous de la zone du palier, en même temps que la bague, constitue une sécurité supplémentaire. Même dans forced into the landing area. A ring of the bearing carries, advantageously, a seal adjacent to the winding drum. When the bearing is mounted in a hoist, in which there is the risk of a fall of the load in the case of damage, the reinforcement of the housing below the bearing area, together with the ring, provides additional security. Even in

Dans un autre développement de l'invention, entre la bague interne et les rouleaux, est disposée une bague écrouie, laminée, ouverte, qui présente une forme de V à son joint. Pour empêcher un échappement des rouleaux, In another development of the invention, between the inner ring and the rollers, is disposed a ring nut, laminated, open, which has a V-shape at its joint. To prevent the rollers from escaping,

Les figures du dessin annexé feront bien comprendre The economically sealed ring guarantees a longer life for the bearing than when the rollers roll directly onto the gray cast iron transmission housing. The figures of the appended drawing will make it clear
