Description

  

  Mouvement d'horlogerie à remontoir automatique.    La     présente    invention a pour objet un  mouvement d'horlogerie à remontoir automa  tique par masse oscillante, dans lequel le  moyeu de la masse, formé d'au moins deux  pièces, présente une partie cylindrique pou  vant tourner dans un palier du bâti et com  prend des épaulements présentant des sur  faces annulaires planes se faisant face et pre  nant appui sur le corps dudit palier pour  absorber les efforts axiaux de la masse oscil  lante.  



  Ce mouvement d'horlogerie est caractérisé  en ce que le palier comprend des rouleaux  disposés autour de la partie cylindrique du  moyeu, ces rouleaux assurant le pivotement  de la masse oscillante.  



  Le dessin annexé représente, à titre  d'exemple, une forme d'exécution de l'objet  (le l'invention.  



  La     fig.    1 est une vue en plan d'une partie  du mouvement, et  la     fig.    2 est une coupe suivant     II-II    de  la     fig.    1.  



  Le mouvement représenté comprend une  masse oscillante formée     d'im    segment de cou  ronne 26, fixé à une planche 27. Cette planche  est elle-même rivée sur une rondelle 28 fai  sant partie du moyeu de la masse. Cette ron  delle présente une     noyure    29 destinée à rece  voir la tête d'une vis 30 prenant dans un  canon cylindrique 31 muni d'une bride ou  flasque 31b, et qui constitue la seconde partie  du moyeu. La vis 30 est coaxiale à l'axe de    rotation de la masse. Le pont du bâti sur le  quel est montée la masse est désigné par 32.  Une pièce annulaire 33, constituant le corps  du palier de la masse, est sertie dans le pont  32.

   Cette pièce annulaire est disposée entre  les parties 28 et 31 du moyeu qui présentent  chacune une surface     annulaire    plane, dé  signée par     28a,    respectivement     31c,    se fai  sant face et prenant appui sur le corps du  palier 33 par l'intermédiaire de billes 34, res  pectivement 35, roulant dans des chemins de  roulement constitués par des rainures circu  laires 36 pratiquées dans le corps de palier  33. Ces billes sont     destinées    à absorber les  efforts axiaux de la masse oscillante. Le ca  non 31 traverse le trou central du corps de  palier 33, des rouleaux 37 étant disposés dans  ce trou autour du canon. Ces     rouleaux    assu  rent le pivotement de la masse oscillante.

   La  vis 30 est empêchée de se desserrer par une  vis auxiliaire 38 prenant dans la rondelle 28.



  Self-winding watch movement. The present invention relates to a clockwork movement with automatic winding by means of an oscillating mass, in which the hub of the mass, formed of at least two parts, has a cylindrical part which can rotate in a bearing of the frame and comprises shoulders having flat annular surfaces facing each other and bearing on the body of said bearing in order to absorb the axial forces of the oscillating mass.



  This clockwork movement is characterized in that the bearing comprises rollers arranged around the cylindrical part of the hub, these rollers ensuring the pivoting of the oscillating mass.



  The appended drawing represents, by way of example, one embodiment of the object (the invention.



  Fig. 1 is a plan view of part of the movement, and FIG. 2 is a section along II-II of FIG. 1.



  The movement shown comprises an oscillating mass formed of a neck segment 26, fixed to a board 27. This board is itself riveted to a washer 28 forming part of the hub of the mass. This ron delle has a core 29 intended to receive the head of a screw 30 taking in a cylindrical barrel 31 provided with a flange or flange 31b, and which constitutes the second part of the hub. The screw 30 is coaxial with the axis of rotation of the mass. The frame bridge on which the mass is mounted is designated by 32. An annular part 33, constituting the body of the mass bearing, is crimped into the bridge 32.

   This annular part is disposed between the parts 28 and 31 of the hub which each have a flat annular surface, designated by 28a, respectively 31c, facing each other and bearing on the body of the bearing 33 by means of balls 34, respectively 35, rolling in raceways formed by circular grooves 36 formed in the bearing body 33. These balls are intended to absorb the axial forces of the oscillating mass. The non-ca 31 passes through the central hole of the bearing body 33, rollers 37 being disposed in this hole around the barrel. These rollers ensure the pivoting of the oscillating weight.

   Screw 30 is prevented from loosening by an auxiliary screw 38 engaging in washer 28.
