Description

       

  Dispositif oscillant comprenant     un    système vibrant     primaire     et     un    système vibrant     secondaire       La présente invention a pour objet un dispositif  oscillant comprenant un système vibrant primaire et un  système vibrant secondaire n'utilisant pas de source  d'énergie électrique pour l'entraînement du système vi  brant primaire. Ce dispositif est caractérisé par le fait  que le système vibrant primaire reçoit l'énergie néces  saire à l'entretien de sa vibration du système vibrant  secondaire à l'exclusion de toute autre source d'énergie.  



       L'utilisation    de ce dispositif est prévue pour tout  appareil à l'exception des appareils destinés à la mesure  du temps.  



  Le dessin annexé représente, à titre d'exemple, une  forme d'exécution du dispositif selon l'invention.  



  Dans un support rigide 1 de masse relativement  élevée par rapport aux masses des systèmes oscillants,  sont montés un système vibrant I constitué par un dia  pason 2 encastré dans le support et dont ses deux  branches portent respectivement à leur extrémité des  masses 3 et 4, et un système vibrant secondaire II cons  titué par une lame vibrante 5 encastrée dans le support  1 et portant à son extrémité une masse oscillante 6.     Le     système vibrant I ne comprend pas d'autres organes que  le diapason représenté, tandis que le système vibrant II  est entretenu mécaniquement ou électriquement par des  moyens non représentés. En outre, l'énergie virtuelle du  diapason est au moins d'un ordre de grandeur supérieur  à celle de la lame vibrante 5.  



  La masse 3 du diapason est séparée de la masse  oscillante 6 de la lame vibrante par un     espace    7 infé  rieur à l'amplitude maximum que l'on peut attendre de  la masse 6 dans des conditions normales de travail et  en ce point. Ainsi, lorsque la lame vibrante 5 est exci  tée, la masse oscillante 6 viendra, au bout de quelques  oscillations, frapper la masse 3 du diapason qui se met  tra à son tour à osciller. Il en résulte un choc qui freine  le système secondaire et     accélère    le système primaire et  l'entretient. On     réalise    ainsi à travers l'espace 7 un    transport d'énergie par voie purement mécanique d'un  système vibrant à l'autre.

   En outre, l'énergie virtuelle  du diapason étant beaucoup plus élevée que celle de la  lame vibrante, la fréquence d'oscillation de cette lame  vibrante sera synchronisée par la fréquence d'oscilla  tion propre du diapason. Le diapason aura généralement  une fréquence d'oscillation qui sera un multiple entier  de la fréquence d'oscillation de la lame vibrante. Cepen  dant, dans certaines applications, il est possible de choi  sir des fréquences égales pour les deux     systèmes    vi  brants, de telle sorte que l'espace 7 peut être réduit à  une valeur voisine ou égale à zéro.  



  Au lieu de réaliser un couplage des deux     systèmes     vibrants par choc élastique, on pourrait utiliser un cou  plage élastique, par exemple un ressort, ou un couplage  magnétique réalisé par des aimants permanents     fixés     en regard l'un de l'autre, respectivement sur chacune  des masses 6 et 3.  



  De nombreuses variantes sont possibles dans le  choix des organes constituant les deux systèmes vi  brants. Au lieu d'une lame vibrante d'un diapason, on  pourrait     utiliser    deux diapasons ou, dans le cas où l'on  désire éliminer l'erreur de position du diapason, par un  résonateur en H ou en 0.  



  Un tel dispositif oscillant trouve de nombreuses ap  plications, en particulier pour la réalisation de filtres de  fréquence ou de diviseur de fréquence.



  Oscillating device comprising a primary vibrating system and a secondary vibrating system The present invention relates to an oscillating device comprising a primary vibrating system and a secondary vibrating system not using a source of electrical energy for driving the primary vibrating system . This device is characterized by the fact that the primary vibrating system receives the energy necessary for maintaining its vibration from the secondary vibrating system to the exclusion of any other source of energy.



       The use of this device is intended for any device with the exception of devices intended for measuring time.



  The appended drawing represents, by way of example, an embodiment of the device according to the invention.



  In a rigid support 1 of relatively high mass compared to the masses of the oscillating systems, are mounted a vibrating system I consisting of a dia pason 2 embedded in the support and whose two branches carry masses 3 and 4 respectively at their end, and a secondary vibrating system II consisting of a vibrating blade 5 embedded in the support 1 and carrying at its end an oscillating mass 6. The vibrating system I does not include other members than the tuning fork shown, while the vibrating system II is maintained mechanically or electrically by means not shown. In addition, the virtual energy of the tuning fork is at least an order of magnitude greater than that of the vibrating blade 5.



  The mass 3 of the tuning fork is separated from the oscillating mass 6 of the vibrating blade by a space 7 less than the maximum amplitude that can be expected of the mass 6 under normal working conditions and at this point. Thus, when the vibrating blade 5 is energized, the oscillating mass 6 will come, after a few oscillations, to strike the mass 3 of the tuning fork which in turn begins to oscillate. This results in a shock which slows down the secondary system and accelerates the primary system and maintains it. A purely mechanical energy transport is thus carried out through space 7 from one vibrating system to another.

   In addition, the virtual energy of the tuning fork being much higher than that of the vibrating blade, the oscillation frequency of this vibrating blade will be synchronized by the frequency of oscillation proper to the tuning fork. The tuning fork will generally have an oscillation frequency which will be an integer multiple of the oscillation frequency of the vibrating blade. However, in some applications it is possible to choose equal frequencies for the two vibrating systems, so that the space 7 can be reduced to a value close to or equal to zero.



  Instead of performing a coupling of the two vibrating systems by elastic shock, one could use an elastic range neck, for example a spring, or a magnetic coupling produced by permanent magnets fixed opposite each other, respectively on each masses 6 and 3.



  Many variations are possible in the choice of the organs constituting the two vibrating systems. Instead of a vibrating blade of a tuning fork, one could use two tuning forks or, in the case where one wishes to eliminate the error of position of the tuning fork, by a resonator in H or in 0.



  Such an oscillating device finds many applications, in particular for the production of frequency filters or frequency divider.
