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  prenant appui     sur    ledit palier pour absorber  les efforts axiaux de la masse oscillante.  



  Ce mouvement d'horlogerie est caractérisé  en ce que ce moyeu est formé de deux parties       assemblées    par une vis coaxiale à l'axe de  rotation de la masse et qui tend à rapprocher  l'une de l'autre lesdites surfaces     annulaires     entre lesquelles est inséré ledit palier du  bâti.  



  Le     dessin    annexé représente, à titre  d'exemple, une forme d'exécution de l'objet  de 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'un segment de cou  ronne 39, fixé à une planche 40. Cette  planche est elle-même rivée sur une rondelle  41     faisant    partie du moyeu de la masse.  Cette rondelle présente une     noyure    42 des  tinée à recevoir la tête d'une vis 43 prenant.  dans un canon cylindrique 44 muni d'une    bride ou<B>.</B> flasque 44b, et qui constitue la  seconde partie du moyeu. La vis 43 est  coaxiale à l'axe de rotation de la masse. Le  pont du bâti sur lequel est montée<B>A</B> la masse  est désigné par 45. Une pièce annulaire 46  constituant le palier de la masse est sertie  dans le pont 45. Cette pièce annulaire est.

    insérée entre les     parties    41 et 44b du moyeu  qui présentent chacune une surface annu  laire plane, désignée par     41a,    respectivement       44a,    se faisant face et prenant appui sur  cette pièce pour absorber les efforts     axiaux     de la masse     39-40.     



  La     vis    43 est empêchée de se-     desserrèr     par une vis auxiliaire 47 se vissant dans la       vis    43 et pénétrant dans la rondelle 41.



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



  This clockwork movement is characterized in that this hub is formed of two parts assembled by a screw coaxial with the axis of rotation of the mass and which tends to bring said annular surfaces between which is inserted. said bearing of the frame.



  The appended drawing represents, by way of example, an embodiment of the object of 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 39, fixed to a board 40. This board is itself riveted to a washer 41 forming part of the hub of the mass. This washer has a core 42 of the tines to receive the head of a screw 43 taking. in a cylindrical barrel 44 provided with a flange or <B>. </B> flange 44b, and which constitutes the second part of the hub. The screw 43 is coaxial with the axis of rotation of the mass. The bridge of the frame on which the mass is mounted <B> A </B> is designated by 45. An annular part 46 constituting the bearing of the mass is crimped into the bridge 45. This annular part is.

    inserted between the parts 41 and 44b of the hub which each have a flat annular surface, designated by 41a, respectively 44a, facing each other and resting on this part to absorb the axial forces of the mass 39-40.



  The screw 43 is prevented from loosening by an auxiliary screw 47 screwing into the screw 43 and penetrating the washer 41.
