Description
Palier amortisseur de chocs pour mobile d'horlogerie. La présente invention a pour objet un palier amortisseur de chocs pour mobile d'hor logerie. Ce palier est .caractérisé par le fait que le contre-pivot est d'un diamètre inférieur à celui du coussinet, et par le fait que le con- tre-pivot est monté dans un ressort fixé au support de palier, ce ressort prenant, en outre, appui sur la face extérieure du coussi net. .
Le dessin annexé représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention et une variante.
La fig. 1 est une coupe axiale d'un palier en position de repos.
La fig. 2 en est ime autre coupe axiale en position de travail.
La fig. 3 est une vue en plan du ressort, et la fig. 4 est une coupe d'un détail d'une variante, à plus grande échelle.
Le palier représenté comprend un support 1 fixé à un coq 2 au moyen d'une clavette 3. Ce support sert en même temps de coqueret, la raquette désignée par 4 étant montée au tour de lui. Une pierre percée 5, formant cous sinet, est montée dans un chaton 6 présentant deux surfaces d'appui, l'une plane, désignée par 7, l'autre oblique, désignée par 8, prenant appui sur le support 1. La pierre percée est surmontée d'une pierre contre-pivot 9, de beaucoup plus petit diamètre, pincée entre des languettes 10a d'un ressort 10.
Ces lan guettes sont découpées dans le ressort 10 et rabattues suivant une direction parallèle à l'axe du palier, leur extrémité prenant appui sur la face extérieure de la pierre percée. Le ressort 10 comprend une partie centrale 10b et deux branches en arc de cercle<B>10e</B> dont les extrémités présentent des talons 10d péné trant dans un logement du support 1, loge ment comprenant une gorge intérieure annu laire 11 et une entrée 15. Des encoches 12 pra tiquées dans les talons 10d du ressort per mettent de le saisir avec des brucelles et de l'armer radialement pour le mettre en place ou l'ôter, en le faisant passer par l'entrée 15 du logement.
Les ouvertures ménagées dans le ressort 10 par le découpage des languettes permettent d'huiler le palier. L'huile est introduite par ces ouvertures, coule le long des languettes et atteint le coussinet.
Les languettes pourraient être remplacées par un manchon annulaire entourant la pierre contre-pivot et obtenu par étampage. .
Dans la variante fig. 4, le ressort comprend une partie plane 13 et un manchon 14 serti sur cette partie plane et contenant la pierre contre-pivot 9 située en retrait, le bord du manchon prenant appui sur la face extérieure de la pierre percée.
Shock-absorbing bearing for watchmaking mobile. The present invention relates to a shock-absorbing bearing for a timepiece mobile. This bearing is characterized by the fact that the counter-pivot is of a diameter smaller than that of the bearing, and by the fact that the counter-pivot is mounted in a spring fixed to the bearing support, this spring taking, in addition, support on the outer face of the net cushion. .
The appended drawing represents, by way of example, an embodiment of the object of the invention and a variant.
Fig. 1 is an axial section of a bearing in the rest position.
Fig. 2 is another axial section in the working position.
Fig. 3 is a plan view of the spring, and FIG. 4 is a section through a detail of a variant, on a larger scale.
The bearing shown comprises a support 1 fixed to a cock 2 by means of a key 3. This support serves at the same time as a cock, the racket designated by 4 being mounted around it. A pierced stone 5, forming a cous sinet, is mounted in a chaton 6 having two bearing surfaces, one flat, designated by 7, the other oblique, designated by 8, resting on the support 1. The pierced stone is surmounted by a counter-pivot stone 9, of much smaller diameter, clamped between tabs 10a of a spring 10.
These lan guettes are cut in the spring 10 and folded in a direction parallel to the axis of the bearing, their end resting on the outer face of the pierced stone. The spring 10 comprises a central part 10b and two branches in an arc of a circle <B> 10th </B>, the ends of which have heels 10d penetrating into a housing of the support 1, housing comprising an annular internal groove 11 and a entry 15. Notches 12 made in the heels 10d of the spring allow it to be grasped with tweezers and to arm it radially in order to put it in place or remove it, by passing it through the entry 15 of the housing.
The openings made in the spring 10 by the cutting of the tabs allow the bearing to be oiled. Oil is introduced through these openings, flows along the tabs and reaches the pad.
The tongues could be replaced by an annular sleeve surrounding the counter-pivot stone and obtained by stamping. .
In the variant fig. 4, the spring comprises a flat part 13 and a sleeve 14 crimped on this flat part and containing the counter-pivot stone 9 located back, the edge of the sleeve resting on the outer face of the pierced stone.
