ROULEMENT A BILLES EN MATIERE PLASTIQUE OU SIMILAIRE
La présente invention a pour obdet un roulement à billes en matière plastique ou similaire, mais en tout état de cause ncn métallique, utilisable comme galet de translation pour diverses utilisations. BALL BEARINGS IN PLASTIC OR SIMILAR MATERIAL
The subject of the present invention is a plastic or similar ball bearing, but in any case metallic ncn, usable as a translation roller for various uses.
On connaît déjà l'utilisation de roulements à billes de translation et de guidage de structures telles que, par exemple, des portes, des grilles coulissantes et similaires. De tels roulements sont généralement produits en métal et aussi en matériau non métallique selon des méthodes connues qui conduisent généralement à des structures et des configurations complexes, surtout au stade de l'assemblage et de la manipulation des éléments qui constituent le roulement et en particulier en ce qui concerne la réception et le logement des billes. We already know the use of ball bearings for translating and guiding structures such as, for example, doors, sliding grids and the like. Such bearings are generally produced in metal and also in non-metallic material according to known methods which generally lead to complex structures and configurations, especially at the stage of assembly and manipulation of the elements which constitute the bearing and in particular in with regard to the reception and housing of the balls.
La présente invention a pour objet de proposer un roulement à billes en matière plastique et en tout état de cause non métallique constituant dans son ensemble un galet de translation et de guidage d'éléments coulissants, qui résolve les inconvénients et les problèmes décrits ci-dessus par l'intermédiaire d'une structure de roulement à billes dont les parties qui la composent soient assemblées de manière simple et sûre et puissent en outre être produits directement par moulage. The object of the present invention is to provide a plastic ball bearing and in any case non-metallic constituting as a whole a roller for translating and guiding sliding elements, which overcomes the drawbacks and the problems described above. by means of a ball bearing structure, the parts of which are composed in a simple and safe manner and can also be produced directly by molding.
Cet obet, ainsi que d'autres, de l'invention apparaîtront bien plus clairement en référence aux dessins joints donnés à titre indicatif et non limitatif, sur lesquels : la figure 1 représente sur une vue éclatée les parties constituant le roulement étudié ; This object, as well as others, of the invention will appear much more clearly with reference to the attached drawings given for information and not limitation, in which: FIG. 1 shows in an exploded view the parts constituting the bearing studied;
<Desc/Clms Page number 2><Desc / Clms Page number 2>
la figure 2 représente en coupe transversale le roulement monté ; et l, élément la figure 3 représenter vu du dessus, l'élément C de la figure sont illustrées Sur ledit dessin, par A, B et C sont illustrées les trois parties constituant le roulement étudié. De manière plus détaillée, la partie A est constituée d'un disque présentant dans sa région centrale un gradin constituant une bague cylindrique 2 définissant un orifice traversant 3 sur la surface interne 4 duquel est ménagée une gorge annulaire 5. Figure 2 shows in cross section the mounted bearing; and the element in FIG. 3 represents seen from above, the element C in the figure are illustrated. In said drawing, by A, B and C are illustrated the three parts constituting the bearing studied. In more detail, part A consists of a disc having in its central region a step constituting a cylindrical ring 2 defining a through orifice 3 on the internal surface 4 of which is formed an annular groove 5.
Le disque 1 présente en outre sur sa face supérieure 6 une pluralité de saillies similaires à des dents 7 sensiblement en forme de V. Lesdites dents présentent chacune deux branches 8, 8' munies de parois externes 9, 9' de profil concave qui définissent et délimitent- une région destinée à recevoir et à retenir, pour une interaction avec la surface latérale de la
bague 2, une pluralité de billes 10 dont le diamètre est plus grand que la hauteur des dents Lesdites billes 10 sont insérées de manière forcée dans leurs logements respectifs, tels que définis cidessus, grâce à l'élasticité adaptée des dents 7, de telle sorte que les billes soient libres de tourner sans toutefois pouvoir sortir desdits logements. The disc 1 also has on its upper face 6 a plurality of projections similar to teeth 7 substantially V-shaped. Said teeth each have two branches 8, 8 'provided with external walls 9, 9' of concave profile which define and delimit- a region intended to receive and to retain, for an interaction with the lateral surface of the
ring 2, a plurality of balls 10 whose diameter is greater than the height of the teeth Said balls 10 are forcibly inserted into their respective housings, as defined above, thanks to the adapted elasticity of the teeth 7, so that that the balls are free to rotate without, however, being able to leave said housings.
Selon l'invention. le roulement se compose en outre
d'une partie C qui présente à son tour un disque 101 sur la face supérieure 61 duquel est ménagé un gradin central constituant une bague 20 délimitant un orifice traversant 30. i-rtf bacfue est outre ménagé, Au-dessus de ladite bague est en outre ménagé, toujours par moulage, un manchon cylindrique 21 muni d'un According to the invention. the bearing is further composed
of a part C which in turn has a disc 101 on the upper face 61 of which is formed a central step constituting a ring 20 delimiting a through orifice 30. i-rtf bacfue is further provided, above said ring is in in addition to being formed, still by molding, a cylindrical sleeve 21 provided with a
<Desc/Clms Page number 3><Desc / Clms Page number 3>
orifice traversant 22 coaxial avec l'orifice 30, ledit manchon présentant une saillie annulaire 23. through orifice 22 coaxial with orifice 30, said sleeve having an annular projection 23.
De manière analogue à ce qui est prévu pour la partie A du roulement, sur la face supérieure 61 est prévue une pluralité de dents 70 présentant la même configuration et les mêmes caractéristiques que les dents 7, lesdites dents 70 étant destinées à retenir une pluralité de billes 1C' libres de tourner. Similarly to what is provided for part A of the bearing, on the upper face 61 is provided a plurality of teeth 70 having the same configuration and the same characteristics as the teeth 7, said teeth 70 being intended to retain a plurality of 1C 'balls free to rotate.
Selon 1 ' invention, le roulement étudié prévoit une troisième partie B constituée d'un anneau 4C présentant une cloison intermédiaire interne 41 qui définit une ouverture centrale circulaire 42 de logement de la bague 20 et qui divise ledit anneau 40 en deux faces dont une supérieure 43 et une inférieure 44. According to the invention, the bearing studied provides a third part B consisting of a ring 4C having an internal intermediate partition 41 which defines a circular central opening 42 for housing the ring 20 and which divides said ring 40 into two faces, one of which is upper 43 and a lower 44.
Lesdites faces 43 et 44 constituent le plan de roulement respectivement des billes 10 de la partie A et des billes 10' de la partie C du roulement au moment de son assemblage qui est obtenu par l'insertion forcée du manchon 21 dans l'orifice traversant 3 après interposition de l'anneau 40 et suite à l'accouplement élastique de la saillie 23 avec la gorge annulaire 5. Said faces 43 and 44 constitute the rolling plane respectively of the balls 10 of the part A and of the balls 10 'of the part C of the bearing at the time of its assembly which is obtained by the forced insertion of the sleeve 21 in the through hole 3 after interposition of the ring 40 and following the elastic coupling of the projection 23 with the annular groove 5.
Il convient de noter que les dents 7 et 70 pourront présenter, sans pour autant sortir de la portée de l'invention, une configuration différente qui permette et garantisse dans tous les cas le logement et la retenue des billes de roulement. It should be noted that the teeth 7 and 70 may have, without departing from the scope of the invention, a different configuration which allows and in all cases guarantees the housing and the retention of the rolling balls.
