Description
Palier à billes pour axe de mobile d'horlogerie L'objet de la présente invention est un pa lier à billes pour axe de mobile d'horlogerie. Ce palier est caractérisé par le fait que la cage renfermant les billes est fermée du côté de l'ex trémité extérieure du palier par une pierre d'horlogerie sur laquelle roulent les billes.
Le dessin ci-annexé représente, à titre d'exemple, deux formes d'exécution de l'objet de la présente invention appliquée à un balan cier de montre, et une variante.
Les fig. 1 et 2 sont des coupes axiales des deux formes d'exécution, respectivement de la variante.
En fig. 1, l'axe A du balancier est monté entre deux paliers. La monture 2 du palier in férieur est chassée dans la platine B et celle, 2a, du palier supérieur se visse dans le coque- ret 3 et appuie par le cône 4 sur la portée élastique 5, ce qui permet de régler le jeu en hauteur du balancier. Le coqueret présente un prolongement qui est chassé dans le coq C. Cette monture contient trois billes 6 équidistan- tes de 1200, mais dont le dessin, pour simplifi cation, n'en représente que deux disposées sur un même diamètre.
La cage de ces billes est fermée à sa partie inférieure par une bague 7 et, à sa partie supérieure, par une pierre d'hor logerie 8 sur laquelle roulent les billes, et qui est sertie dans la monture du palier.
Le palier inférieur est semblable au palier supérieur avec cette différence qu'il n'est pas réglable en hauteur et que le fond supérieur 7a de la cage des billes est venu de fabrication avec la monture du palier.
Enfin, dans la variante de la fig. 2, 1a pierre 8, au lieu d'être sertie dans la monture, repose sur un épaulement de celle-ci et est maintenue en place par une bride élastique 9.
Ball bearing for a clockwork mobile axis The object of the present invention is a ball bearing for a clockwork mobile axis. This bearing is characterized by the fact that the cage containing the balls is closed on the side of the outer end of the bearing by a timepiece on which the balls roll.
The appended drawing represents, by way of example, two embodiments of the object of the present invention applied to a watch balance, and a variant.
Figs. 1 and 2 are axial sections of the two embodiments, respectively of the variant.
In fig. 1, the axis A of the balance is mounted between two bearings. The frame 2 of the lower bearing is driven into the plate B and that, 2a, of the upper bearing is screwed into the shell- retaining 3 and presses by the cone 4 on the elastic bearing surface 5, which makes it possible to adjust the height clearance of the balance. The cockerel has an extension which is driven into the cock C. This frame contains three equidistant balls 6 of 1200, but the design of which, for simplification, represents only two arranged on the same diameter.
The cage of these balls is closed at its lower part by a ring 7 and, at its upper part, by a timepiece 8 on which the balls roll, and which is crimped in the bearing frame.
The lower bearing is similar to the upper bearing with the difference that it is not adjustable in height and that the upper bottom 7a of the ball cage came from manufacture with the mounting of the bearing.
Finally, in the variant of FIG. 2, the stone 8, instead of being set in the frame, rests on a shoulder of the latter and is held in place by an elastic flange 9.
