Abstract
Description
Dans une pièce d'horlogerie mécanique comprenant un
système balancier-spiral à échappement suisse, la période
d'oscillation du balancier est donnée par la formule
Si ce rapport est constant, le mouvement est isochrone.If this ratio is constant, the movement is isochronous.
Malheureusement, lors de la marche de la pièce, de nombreux facteurs, qui dépendent notamment des positions du système réglant, modifient la valeur du rapport I / CUnfortunately, during the walk of the piece, many factors, which depend in particular on positions of the regulating system, modify the value of the I / C ratio
Un des facteurs les plus importants réside dans les forces de frottement, en particulier celles qui agissent sur les pivots du balancier.One of the most important factors is the strengths friction, especially those that act on the pendulum pivots.
Ces forces de frottement entrainent des variations ΔT de la période d'oscillation T du balancier.These friction forces cause variations ΔT of the period of oscillation T of the balance wheel.
Pour réduire ces écarts, l'horloger Breguet a inventé le tourbillon qui consiste à loger les organes du système réglant dans une cage, coaxiale au balancier, de manière que les écarts se compensent au moins partiellement lors des mouvements aléatoires de la pièce. To reduce these differences, the watchmaker Breguet invented the vortex which consists of housing the organs of the system adjusting in a cage, coaxial with the balance, so that the differences at least partially compensate for each other during random movements of the part.
Le but de la présente invention est de réduire davantage la somme des écarts ΔT durant un intervalle de temps relativement long, par exemple 24 heures, et d'améliorer ainsi la précision de la pièce.The object of the present invention is to further reduce the sum of the deviations ΔT during a time interval relatively long, say 24 hours, and improve thus the precision of the part.
A cet effet, le système réglant est logé dans une cage et la pièce comprend un mécanisme imprimant à cette cage un mouvement au cours duquel tous les points matériels du sytème réglant décrivent des trajectoires dans un espace à trois dimensionsFor this purpose, the regulating system is housed in a cage and the piece includes a mechanism printing to this cage a movement in which all the points materials of the regulating system describe trajectories in a three-dimensional space
Le dessin ci-annexé représente, schématiquement et à titre d'exemple non limitatif, une montre-bracelet constituant une forme d'exécution de l'objet de l'invention.The attached drawing represents, schematically and by way of non-limiting example, a wristwatch constituting an embodiment of the subject of the invention.
Pour simplifier, on a représenté seulement la cage et son mécanisme d'entraínement, ainsi qu'une partie du système réglant.To simplify, we have shown only the cage and its drive mechanism, as well as part of the regulating system.
La figure unique du dessin est une coupe par l'axe commun A1 de la cage et du balancier.The single figure of the drawing is a section through the common axis A1 of the cage and the pendulum.
Le système réglant de la montre-bracelet, comprenant le
balancier 10 et le pignon d'échappement 11, est logé
dans une cage 12 dont le pont supérieur 13 présente une
couronne dentée 14.The adjusting system of the wristwatch, including the
Cette cage 12 est fixée sur un plateau ( plateforme )
15 qui est solidaire de la roue de seconde 16 laquelle
engrène avec le pignon 11.This
Le plateau 15 est monté rotativement entre deux pierres-glaces
17 et 18 disposées dans des logements prévus à
cet effet, respectivement dans le moyeu 19 de deux roues
dentées jumelées 20 et 21, et dans le moyeu 22 d'une roue
dentée 23.The
Les trois roues 20, 21 et 23 ont un axe commun A2 coupant
perpendiculairement l'axe A1.The three
Les roues jumelées 20-21 peuvent tourner dans un palier
à billes 24, tandis que le moyeu 22 est châssé dans un
logement d'un support 25.Twin wheels 20-21 can rotate in a
Le palier 24 et le support 25 sont montés en des points diamètralement opposés
d'une roue motrice 26 qui tourne, par l'intermédiaire
d'un roulement à billes 27, dans une bague 28 fixée
sur le fond de la boíte, et qui porte une crémaillère
circulaire 29 sur laquelle la roue 20 prend appui.The
La roue motrice 26 exerce en permanence une action sur
la roue 20 qui tend à la faire tourner autour de son axe
A2. The
En faisant l'hypothèse que rien n'empêche de raire tourner librement la roue 26 autour de l'axe A1, cette rotation communiquerait à l'ensemble 12-15, par l'interdiaire de la crémaillère 29 et de la roue 20, les mouvements suivants :
- une rotation autour de l'axe A1, par engrènement de la roue 21 et de la couronne 14,
- une rotation autour de l'axe A2, par engrènement
en deux points diamètralement opposés, de la couronne
14 avec, d'une part, la
roue 21, et, d'autre part, laroue fixe 23.
- a rotation about the axis A1 , by meshing of the
wheel 21 and thecrown 14, - a rotation about the axis A2 , by meshing at two diametrically opposite points, of the
crown 14 with, on the one hand, thewheel 21, and, on the other hand, the fixedwheel 23.
La vue en perspective isométrique jointe au dessin a pour but d'illustrer le fonctionnement du mécanisme d'entrainement de la cage ; elle n'est pas une pièce technique de la demande.The isometric perspective view attached to the drawing a to illustrate the operation of the mechanism cage training; she is not a room demand technique.
Le mouvement résultant de ces deux rotations qui s'exécutent pratiquement simultanément s'étend dans un espace à trois dimensions par rapport à un système de référence fixe.The movement resulting from these two rotations which are performed practically simultaneously extends into a space of three dimensions compared to a fixed reference system.
Au cours de ce mouvement résultant, tous les points du système réglant passent par des positions correspondant à des positions verticales et horizontales de la montre.During this resulting movement, all points of the regulating system go through corresponding positions at vertical and horizontal positions of the watch.
En abandonnant l'hypothèse ci-dessus, le pignon
d'échappement 11 rend ce mouvement résultant intermittent
par le fait qu'il ne peut s'opérer que durant une
alternance sur deux du balancier 10.By abandoning the hypothesis above, the
Durant sa rotation, le pignon 11, en engrenant avec la
roue de secondes, 16 décrit une trajectoire épicycloïdale.During its rotation, the
Les mouvements aléatoires de la montre contribuent à faire tendre vers zéro la somme des écarts Δ T durant un intervalle de temps prolongé.The random movements of the watch contribute to bring the sum of the deviations Δ T to zero during one extended time interval.
On sait en effet, que les écarts de marche ΔT,
c'est-à-dire
Les mouvements de la cage de la pièce selon l'invention font donc tendre la somme totale des écarts ΔT vers zéro. The movements of the workpiece cage according to the invention thus make tend the total sum of the deviations ΔT towards zero.
On notera encore que les perturbations de marche de la montre causées dans le mécanisme d'entrainement au niveau des engrenages, d'une part, et des tourbillons et leurs paliers d'autre part, lorsque les points de contact, se déplacent, par exemple au moment du passage de l'ensemble 12- 15 par des positions d'équilibre instables, se compenseront, au moins partiellement dans le temps grâce au mouvement de cet ensemble.It will also be noted that the disturbances in the walking of the shows caused in the drive mechanism at the level gears, on the one hand, and vortices and their bearings on the other hand, when the contact points, move, for example when passing of the set 12-15 by unstable equilibrium positions, offset each other, at least partially in the time thanks to the movement of this set.
L'invention n'est évidemment pas limitée à la forme d'exécution décrite. En particulier elle pourra s'appliquer à d'autres pièces d'horlogerie que des montres-bracelets.The invention is obviously not limited to the form of execution described. In particular it may apply other timepieces than wristwatches.
Par ailleurs, le mécanisme d'entrainement de la cage pourra être différent de celui décrit et représenté.In addition, the drive mechanism of the cage may be different from that described and represented.
