Description

  

   <Desc/Clms Page number 1> 
 Dispositif    oscillant   d'horlogerie On    connait   des dispositifs oscillants    comprenant   un balancier d'horlogerie sur l'axe duquel est chassée une virole pour la fixation du spiral, par l'intermédiaire d'une bague chassée sur le corps de la virole en pinçant le spiral contre un épaulement de    celle-ci.   Ces viroles présentent cependant    l'inconvénient   d'être soumises à des    sollicitations   mécaniques élevées lors de leur chassage sur l'axe de balancier et du chassage de la bague ;

      ces   sollicitations peuvent provoquer des déformations de la    virole   qui se    traduisent      par   un mauvais pincement du spiral et par une    assise      défectueuse   de la virole sur le balancier. 



  On a déjà eu l'idée de parer à des    déformations   de ce genre dans la fixation de moyeux de balancier sur un axe en    limitant   le contact entre    ces   deux pièces aux seules extrémités du moyeu, mais l'on n'a jamais pris des    mesures   de    ce   genre pour la fixation d'une virole présentant une bague de tension pour le    pincement   du    spiral.   



  La présente invention a pour objet un dispositif    oscillant   d'horlogerie comprenant une virole chassée sur un axe de balancier et munie d'une    bague   chassée pour pincer le spiral. Ce dispositif est caractérisé    par   le fait que seules    #   les deux    extrémités   de cette virole sont en contact avec l'axe de    ce   balancier et que la bague est, une fois le spiral en place, disposée entre    ces   deux    extrémités.   



  La    fig.   1 du dessin représente, à titre d'exemple, une forme d'exécution de l'objet de la présente invention. 



  Au dessin le balancier 1 est monté sur un arbre 2 dont la partie supérieure présente deux épaulements 3 sur lesquels est chassée une virole 5 ; la position de    ces   épaulements correspond aux deux extrémités de la virole. 



  Le spiral 4 est pincé entre un épaulement de la virole et une bague 6 chassée sur    cette   dernière. Cette bague une fois en    place   est disposée dans la partie centrale de la    virole,   c'est-à-dire entre les deux zones où elle est    sollicitée   par les épaulements 3 de l'arbre. Dans une    variante   non représentée,    il   serait bien entendu possible d'utiliser un axe    cylindrique   et de prévoir des épaulements non pas sur    cet   axe mais    dans   la masse de la virole ; il suffirait à    cet   effet    d'aléser   légèrement la partie centrale du trou de    cette   virole. 



  Enfin pour    améliorer   l'assise de la    virole      il   est encore    possible   d'usiner dans le balancier une petite    creusure   7    dans   le fond de laquelle vient buter l'extrémité 8 de la virole. 



  La position relative de la bague 6 par rapport aux    épaulements   3 permet de parer aux effets des déformations dues au chassage de    ces   divers    éléments   l'un sur l'autre. On évite    ainsi   la    transmission   de    ces   déformations au spiral ou au    balancier,   améliorant ainsi la qualité du réglage de la    pièce.

 Oscillating clockwork device Oscillating devices are known comprising a clockwork balance on the axis of which is driven a ferrule for fixing the hairspring, via a ring driven on the body of the ferrule by pinching the hairspring. against a shoulder of it. However, these ferrules have the drawback of being subjected to high mechanical stresses when they are driven on the balance axis and when the ring is driven;

      these stresses can cause deformation of the ferrule which results in poor clamping of the balance spring and faulty seating of the ferrule on the balance.



  We have already had the idea of dealing with deformations of this kind in the fixing of balance hubs on an axle by limiting the contact between these two parts at the only ends of the hub, but we have never taken any measures. of this kind for fixing a ferrule having a tension ring for clamping the hairspring.



  The present invention relates to a clockwork oscillating device comprising a ferrule driven on a balance axis and provided with a driven ring for clamping the hairspring. This device is characterized in that only # the two ends of this ferrule are in contact with the axis of this balance and that the ring is, once the spring is in place, placed between these two ends.



  Fig. 1 of the drawing shows, by way of example, an embodiment of the object of the present invention.



  In the drawing, the balance 1 is mounted on a shaft 2, the upper part of which has two shoulders 3 on which a ferrule 5 is driven; the position of these shoulders corresponds to the two ends of the shell.



  The spiral 4 is clamped between a shoulder of the ferrule and a ring 6 driven on the latter. Once in place, this ring is placed in the central part of the shell, that is to say between the two zones where it is stressed by the shoulders 3 of the shaft. In a variant not shown, it would of course be possible to use a cylindrical axis and to provide shoulders not on this axis but in the mass of the shell; it would suffice for this purpose to slightly bore the central part of the hole in this ferrule.



  Finally, to improve the seat of the shell, it is still possible to machine a small recess 7 in the balance 7 in the bottom of which the end 8 of the shell abuts.



  The relative position of the ring 6 with respect to the shoulders 3 makes it possible to counter the effects of deformations due to the driving of these various elements one on the other. This prevents the transmission of these deformations to the hairspring or to the balance, thus improving the quality of the part adjustment.
