Description

MOUVEMENT D'HORLOGERIE WATCHMAKING MOVEMENT
La présente invention se rapporte à un mouvement d'horlogerie comprenant un ressort de barillet logé dans un baril- let, un rouage de finissage, un échappement et un balancier- spiral dans lequel le barillet et le balancier-spiral sont coaxiaux.The present invention relates to a watchmaking movement comprising a barrel spring housed in a barrel, a finishing gear, an escapement and a balance spring in which the barrel and the sprung balance are coaxial.
On sait que la réserve de marche d'une pièce d'horlogerie entraînée par un ressort de barillet est fonction du dia- mètre du barillet qui est limité par la présence des aiguilles et des mobiles qui les entraînent, généralement situés plus ou moins au centre du mouvement de montre. Or on sait que plus la réserve de marche du ressort de barillet est grande, plus l'énergie transmise au balancier à travers le rouage de finissage et l'échappement est constante, ce qui constitue un facteur permettant d' améliorer la précision du système réglant.It is known that the power reserve of a timepiece driven by a mainspring is a function of the diameter of the barrel which is limited by the presence of the needles and the mobiles which drive them, generally located more or less in the center. of the watch movement. However, it is known that the greater the power reserve of the mainspring, the more energy transmitted to the balance through the work train and the exhaust is constant, which is a factor to improve the accuracy of the regulating system. .
Pour les mêmes raisons, la présence des mobiles portant les aiguilles indicatrices limite le diamètre du balancier- spiral. Or on sait que plus le diamètre du balancier est grand, plus la régularité de sa fréquence est grande. Pour un moment d'inertie donné, la masse du balancier est réduite en proportion de l'augmentation de son rayon, le moment d'inertie étant le produit de sa masse par son rayon au carré. On a déjà proposé de disposer le barillet et la balancier-spiral coaxiaux, dans EP 0 681 227 Al. Par contre on n'a pas utilisé cette disposition particulière du barillet et du balancier-spiral pour augmenter sensiblement leurs diamètres respectifs . Le but de la présente invention est de permettre de s'affranchir des contraintes susmentionnées liées à la présence des axes des mobiles porteurs des aiguilles indicatrices . A cet effet, l'invention a principalement pour objet un mouvement d'horlogerie selon la revendication 1.For the same reasons, the presence of the mobiles carrying the indicator hands limits the diameter of the sprung balance. Now we know that the greater the diameter of the pendulum, the greater the regularity of its frequency. For a given moment of inertia, the mass of the pendulum is reduced in proportion to the increase of its radius, the moment of inertia being the product of its mass by its radius squared. It has already been proposed to arrange the coaxial barrel and coaxial balance spring in EP 0 681 227 A1. On the other hand, this particular arrangement of the barrel and the balance-spring has not been used to substantially increase their respective diameters. The object of the present invention is to overcome the aforementioned constraints related to the presence of the axes of the mobile pointer indicator carriers. For this purpose, the subject of the invention is mainly a watch movement according to claim 1.
De préférence, le barillet et le balancier spiral sont coaxiaux à l'axe central du mouvement d'horlogerie. Grâce à cette disposition coaxiale, avec l'axe central du mouvement dans une forme préférée de l'invention, le diamètre du barillet peut être pratiquement doublé. Ceci permet de réduire la perte de puissance du ressort de barillet en 24 heures à environ 8% alors qu'elle se situe en général aux environs de 20%.Preferably, the barrel and the balance spring are coaxial with the central axis of the watch movement. Thanks to this coaxial arrangement, with the central axis of the movement in a preferred form of the invention, the diameter of the barrel can be practically doubled. This reduces the power loss of the mainspring in 24 hours to about 8% while it is generally around 20%.
Le diamètre du balancier peut aussi être pratiquement doublé, ainsi à masse égale, on peut avoir un balancier de plus grande inertie, ou pour une inertie donnée, on peut avoir un balancier de masse sensiblement plus faible. Tout compromis entre ces deux extrêmes étant évidemment envisageable.The diameter of the balance can also be practically doubled, so with equal mass, one can have a balance of greater inertia, or for a given inertia, one can have a substantially lower balance of mass. Any compromise between these two extremes is obviously conceivable.
Le dessin annexé illustre, schématiquement et à titre d'exemple, une forme d'exécution du mouvement d'horlogerie objet de la présente invention. La figure 1 est une vue éclatée de cette forme d'exécution; la figure 2 en est une vue de dessus; la figure 3 est une vue en coupe selon III-III de la figure 2. Le mouvement d'horlogerie selon la présente invention présente la particularité que le barillet et le balancier sont coaxiaux et que le rouage de finissage et le rouage indicateur de l'heure et des minutes comportent des mobiles d'engrenages planétaires également coaxiaux à l'axe commun du barillet et du balancier.The accompanying drawing illustrates, schematically and by way of example, an embodiment of the watch movement object of the present invention. Figure 1 is an exploded view of this embodiment; Figure 2 is a view from above; FIG. 3 is a sectional view along III - III of FIG. 2. The clockwork movement according to the present invention has the particularity that the barrel and the balance are coaxial and that the finishing gear train and the indicator gear train of the hour and minutes include planetary gear mobiles also coaxial with the common axis of the barrel and the balance.
Le mouvement est monté dans un bâti B en forme de cage ou de calotte, autour d'une colonne tubulaire centrale 1 tenue sur le bâti B par un écrou 2 vissé à une extrémité de la colonne tubulaire 1. Une bonde 3 d'un barillet 4 est montée libre autour de la colonne tubulaire 1. Comme toute bonde, la bonde 3 comporte une portion de section droite polygonale 3a sur laquelle est ajusté un rochet de remontage 5 en prise avec un renvoi de remontoir 6 qui peut être lui- même en prise avec un organe d'entraînement accessible de l'extérieur du mouvement. Il peut s'agir d'une clé de remontage (non représentée) montée sur le fond de la boîte (non représentée) ou alors d'une bague munie d'une denture interne, montée en rotation sur le fond de la boîte, à l'instar d'une lunette tournante. Il pourrait aussi s'agir, plus classiquement d'un pignon solidaire d'une tige de remontoir, mais dans ce cas, il faudrait réduire quelque peu le diamètre du barillet 4. Le barillet 4 renferme un ressort de barillet R dont l'extrémité interne est fixée à la bonde 3 et dont l'extrémité externe est fixée à la face interne de la paroi latérale du tambour de barillet.The movement is mounted in a frame B in the form of a cage or cap, around a central tubular column 1 held on the frame B by a nut 2 screwed to one end of the tubular column 1. A plug 3 of a barrel 4 is mounted free around the tubular column 1. Like any plug, the plug 3 comprises a portion of polygonal cross section 3a on which is fitted a winding ratchet 5 engaged with a winder return 6 which can itself be engaged with a drive member accessible from outside the movement. It may be a winding key (not shown) mounted on the bottom of the box (not shown) or a ring provided with an internal toothing, mounted in rotation on the bottom of the box, to like a rotating bezel. It could also be, more conventionally a pinion secured to a winding stem, but in this case, it would reduce somewhat the diameter of the barrel 4. The barrel 4 contains a barrel spring R whose end internal is attached to the plug 3 and whose outer end is fixed to the inner face of the side wall of the barrel drum.
Une particularité de ce mouvement d'horlogerie réside dans le fait que le rouage de finissage ne comporte qu'un mobile des secondes 7 comprenant trois paires de pignons planétaires 7a, 7b réparties à 120° à la périphérie de deux anneaux 7d, 7e maintenus écartés et assemblés par trois piliers 7g répartis à 120° à la périphérie des anneaux 7d, 7e et à 60° de chaque paire de pignons planétaires 7a, 7b, comme on peut le voir sur la figure 1. L'un des pignons planétaire est solidaire d'un arbre 7c pivoté dans deux paliers solidaires respectivement des anneaux 7d, 7e, l'autre pignon planétaire est aussi monté solidaire de l'arbre 7c. Le pignon pla- nétaire 7a engrène avec une denture 4a solidaire du barillet 4 et le pignon planétaire 7b engrène avec une denture fixe la ménagée le long du bord d'une assiette Ib, solidaire de la colonne tubulaire centrale 1. L'anneau supérieur 7e comporte une denture interne 7f qui engrène avec un pignon 8a d'une roue d'échappement 8, montée sur l'assiette Ib solidaire de la colonne tubulaire centrale 1. La roue d'échappement est contrôlée comme dans tous les échappements à ancre, par une ancre d'échappement 9, dont le basculement entre deux goupilles (non représentées) est provoqué par le passage d'une cheville solidaire d'un double plateau 10 fixé sur l'arbre du balancier 11.A peculiarity of this watch movement lies in the fact that the finishing train comprises only a second wheel 7 comprising three pairs of planetary gears 7a, 7b distributed at 120 ° to the periphery of two rings 7d, 7e kept apart and assembled by three pillars 7g distributed at 120 ° at the periphery of the rings 7d, 7e and 60 ° of each pair of planetary gears 7a, 7b, as can be seen in FIG. 1. One of the planetary gears is secured 7c of a shaft pivoted in two integral bearings respectively rings 7d, 7e, the other sun gear is also mounted integral with the shaft 7c. The planet gear 7a meshes with a toothing 4a integral with the barrel 4 and the sun gear 7b meshes with a fixed toothing arranged along the edge of a plate Ib, integral with the central tubular column 1. The upper ring 7e has an internal toothing 7f which meshes with a pinion 8a of an escape wheel 8, mounted on the plate Ib integral with the central tubular column 1. The escape wheel is controlled as in all anchor escapements, by an exhaust anchor 9, whose tilting between two pins (not shown) is caused by the passage of a fixed ankle of a double plate 10 fixed on the balance shaft 11.
Le pivotement du mobile des secondes 7 est obtenu par deux roulements à billes 12, 13. Il est à noter que la face supérieure de l'anneau 7e peut être munie d'un repère (non représenté) destiné à indiquer les secondes.The pivoting of the mobile seconds 7 is obtained by two ball bearings 12, 13. It should be noted that the upper face of the ring 7e may be provided with a mark (not shown) for indicating the seconds.
Le barillet 4 porte une seconde denture 4b qui engrène avec trois roues 14a du mobile des heures 14 réparties angulairement à 120° les unes des autres autour de l'axe central de la colonne tubulaire 1. Ces roues 14a, dont seule l'une est visible sur la figure 3, mais que l'on peut voir sur la figure 1, sont pivotées entre deux anneaux 14b, 14c, assemblés et maintenus écartés par trois piliers 14d répartis à 120° les uns des autres avec un décalage de 60° par rapport aux roues 14a. Ces roues 14a engrène avec un anneau à denture interne 27, monté à frottement gras sur le bâti B, de sorte qu'en fonctionnement normal, cet anneau peut être considéré comme un anneau fixe par rapport au bâti B. Les deux anneaux 14b, 14c du mobile des minutes sont pivotes et guidés par le roulement à billes 12 et un roulement à billes 15.The barrel 4 carries a second toothing 4b which meshes with three wheels 14a of the mobile 14 hours angularly distributed at 120 ° from each other around the central axis of the tubular column 1. These wheels 14a, of which only one is 3, but that can be seen in FIG. 1, are pivoted between two rings 14b, 14c, assembled and held apart by three pillars 14d distributed at 120 ° to each other with a 60 ° offset by relative to the wheels 14a. These wheels 14a meshes with an internally toothed ring 27, frictionally mounted on the frame B, so that in normal operation, this ring can be considered as a fixed ring relative to the frame B. The two rings 14b, 14c the mobile minutes are pivoted and guided by the ball bearing 12 and a ball bearing 15.
L'anneau supérieur 14c porte une denture interne 14e engrenant avec un premier pignon planétaire 16a du mobile des minutes 16. Un second pignon planétaire 16b est monté solidaire du même arbre que le premier pignon planétaire 16a. Ce second pignon planétaire engrène avec une denture fixe Ba solidaire du bâti B. Trois paires de pignons planétaires 16a, 16b sont réparties à 120° les une des autres entre deux anneaux lβc, lβd, assemblés et maintenus écartés par trois piliers 16e répartis à 120° les uns des autres et à 60° des paires de pignons planétaires 16a, 16b, comme on peut le voir sur la figure 1.The upper ring 14c has an internal toothing 14e meshing with a first sun gear 16a of the minute wheel 16. A second sun gear 16b is mounted integral with the same shaft as the first sun gear 16a. This second sun gear meshes with a fixed toothing Ba secured to the frame B. Three pairs of planetary gears 16a, 16b are distributed at 120 ° to one another between two rings lβc, lβd, assembled and held apart by three pillars 16e distributed at 120 ° to each other and 60 ° pairs of planetary gears 16a, 16b, as can be see Figure 1.
Le guidage et le pivotement des anneaux 14b, 14c est obtenu par deux roulements à billes 17 et 18. Une plaque supérieure ajourée 19 sert à maintenir l'ensemble des rouages planétaires sur la bâti B. Cette plaque 19 porte en son centre un palier antichoc 20 pour une extrémité de l'arbre de balancier 11, alors que le second palier 21 est solidaire de la colonne tubulaire centrale 1. Comme habituellement, un piton 22 et une raquette 23 (figure 1) pour la fixation, respectivement le réglage de la longueur active du spiral 24, sont montés autour du palier supérieur 20 de l'arbre de balancier 11.The guiding and pivoting of the rings 14b, 14c is obtained by two ball bearings 17 and 18. A perforated upper plate 19 serves to hold the assembly of the planetary wheels on the frame B. This plate 19 carries in its center a shockproof bearing 20 for one end of the balance shaft 11, while the second bearing 21 is integral with the central tubular column 1. As usual, a pin 22 and a racket 23 (Figure 1) for fixing, respectively the adjustment of the active length of the spiral 24, are mounted around the upper bearing 20 of the balance shaft 11.
Un pignon de mise à l'heure 25 est monté pivotant entre le bâti B et la plaque supérieure 19. Ce pignon est par exemple destiné à venir en prise avec une denture d'une lunette tournante (non représentée) de la boite de montre. Ce pignon de mise à l'heure 25 engrène avec un renvoi 26 engrenant par ailleurs avec une denture externe 27a de l'anneau 27 monté à frottement gras sur le bâti B, permettant d'effectuer la mise à l'heure lorsque le pignon 25 transmet à l'anneau 27 un couple supérieur à la force de frottement que l'empêche normalement de tourner. Il s'agit du même principe que celui utilisé dans la mise à l'heure classique par l'intermédiaire d'une chaussée lanternée sur l'arbre de la roue de centre. II est évident que la forme d'exécution décrite à titre d'exemple pourrait être modifiée sur plusieurs points, tels que les organes de guidage des engrenages planétaires, le nombre de pignons planétaires sans sortir de l'invention re- vendiquée. On pourrait aussi envisager de faire une inversion entre les mobiles des heures 14 et des minutes 16 sans sortir du cadre de l'invention. A setting gear 25 is pivotally mounted between the frame B and the upper plate 19. This pinion is for example intended to engage with a toothing of a rotating bezel (not shown) of the watch case. This time-setting pinion meshes with a return 26 meshing also with an external toothing 27a of the ring 27 mounted frictionally on the frame B, making it possible to set the time when the pinion 25 transmits to the ring 27 a torque greater than the friction force that normally prevents it from rotating. This is the same principle as used in conventional time setting via a lanterned roadway on the shaft of the center wheel. It is obvious that the embodiment described by way of example could be modified on several points, such as planetary gear guide members, the number of planet gears without departing from the invention. vendiquée. One could also consider making a reversal between the mobiles 14 hours and minutes 16 without departing from the scope of the invention.
