Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine de l'horlogerie mécanique et concerne, plus particulièrement, une pièce d'horlogerie dont le barillet est agencé de manière avantageuse.The present invention relates to the field of mechanical watchmaking and more particularly relates to a timepiece whose barrel is advantageously arranged.

Le barillet est l'organe moteur utilisé dans les montres mécaniques. Il agit comme accumulateur d'énergie en étant armé par l'utilisateur ou par une masse oscillante et en restituant progressivement au rouage de la montre l'énergie qu'il a emmagasinée.The barrel is the driving organ used in mechanical watches. It acts as an energy accumulator by being armed by the user or by an oscillating mass and by gradually restoring to the wheel of the watch the energy that it has stored.

Etat de la techniqueState of the art

Un barillet de type conventionnel comporte :

  • un tambour de barillet, qui est une sorte de boîte cylindrique comprenant un fond et des parois latérales, le tambour étant muni d'une denture extérieure pour entraîner le rouage,
  • un arbre de barillet pivotant entre pont et platine et muni d'un crochet disposé sur sa bonde,
  • un ressort lame fixé, par une première extrémité à un dégagement opéré sur le diamètre intérieur des parois latérales du tambour et, par une deuxième extrémité au crochet de l'arbre de barillet, et
  • un couvercle fermant le tambour.
A barrel of conventional type comprises:
  • a barrel drum, which is a kind of cylindrical box having a bottom and side walls, the drum being provided with an external toothing to drive the gear,
  • a cylinder shaft pivoting between bridge and plate and provided with a hook disposed on its bung,
  • a leaf spring fixed at a first end to a clearance operated on the inside diameter of the side walls of the drum and, by a second end to the hook of the barrel shaft, and
  • a lid closing the drum.

Le tambour et le couvercle servent généralement de pivotement à l'arbre de barillet afin de stabiliser ce dernier. Un rochet est monté solidaire de l'arbre de barillet, généralement à carré. Il est entraîné par un dispositif de remontage, manuel ou automatique, pour faire pivoter l'arbre et armer le ressort de barillet.The drum and the lid are generally pivoted to the barrel shaft to stabilize the barrel shaft. A ratchet is mounted integral with the barrel shaft, generally square. It is driven by a winding device, manual or automatic, to rotate the shaft and arm the barrel spring.

L'homme du métier sait que l'un des facteurs principaux pour améliorer le rendement d'un mouvement est la qualité des pivotements des différents éléments et la faiblesse des frottements impliqués. Ce point est particulièrement essentiel au niveau du barillet où les forces qui s'exercent sont importantes et où les défauts dans le guidage de l'arbre et du tambour peuvent avoir des conséquences non négligeables au niveau de la réserve de marche.The skilled person knows that one of the main factors to improve the performance of a movement is the quality of the pivoting of the various elements and the weakness of the friction involved. This point is particularly essential at the barrel where the forces that are exerted are important and where the defects in the guidance of the shaft and the drum can have significant consequences at the level of the power reserve.

Le document CH 610178 propose, dans le but d'améliorer la qualité de pivotement du barillet, de le monter en porte-à-faux au moyen d'un roulement à bille. L'arbre de barillet est chassé à l'intérieur de la bague intérieure de ce roulement tandis que la bague extérieure est fixée dans un logement ménagé dans la platine. En outre, le tambour est pivoté par l'extérieur au moyen de galets avec lesquels il coopère.The document CH 610178 proposes, with the aim of improving the pivoting quality of the barrel, to mount it cantilevered by means of a ball bearing. The barrel shaft is driven into the inner ring of this bearing while the outer ring is fixed in a housing in the plate. In addition, the drum is pivoted from the outside by means of rollers with which it cooperates.

Or, la présence des galets est particulièrement gênante au niveau de l'encombrement que ceux-ci génèrent. En outre, l'expérience montre que la précision du dispositif proposé dans le document susmentionné n'est pas très satisfaisante. La présente invention a pour but non seulement de pallier cet inconvénient, mais aussi d'améliorer le pivotement du barillet.However, the presence of the rollers is particularly troublesome in terms of the size that they generate. In addition, experience shows that the accuracy of the device proposed in the above-mentioned document is not very satisfactory. The present invention aims not only to overcome this disadvantage, but also to improve the pivoting of the barrel.

Le document WO 2008/046750 divulgue un barillet pivoté à l'aide d'un roulement à billes à trois bagues.The document WO 2008/046750 discloses a barrel rotated using a ball bearing with three rings.

Divulgation de l'inventionDisclosure of the invention

De façon plus précise, selon l'invention, le tambour est pivoté par un premier roulement à billes comprenant une bague intérieure solidaire de l'arbre, une bague intermédiaire, et une bague extérieure, l'une des bagues intermédiaire et extérieure étant fixée au pont de barillet, l'autre étant solidaire dudit fond.More specifically, according to the invention, the drum is pivoted by a first ball bearing comprising an inner ring integral with the shaft, an intermediate ring, and an outer ring, one of the intermediate and outer rings being fixed to the barrel bridge, the other being secured to said bottom.

Selon un autre aspect, l'invention concerne également un barillet dont l'arbre est monté volant, c'est-à-dire qu'il n'est pivoté que par l'une de ses extrémités, au moyen d'un roulement comprenant trois bagues, coplanaires, dont une bague parmi les bagues intermédiaire et extérieure est fixée à un élément du bâti (pont ou platine), l'autre bague parmi les bagues intermédiaire et extérieure est fixée au fond du tambour, et la bague intérieure est fixée à l'arbre.According to another aspect, the invention also relates to a cylinder whose shaft is mounted flying, that is to say that it is pivoted only by one of its ends, by means of a bearing comprising three rings, coplanar, one ring of the intermediate and outer rings is attached to a frame element (bridge or plate), the other ring of the intermediate and outer rings is fixed to the bottom of the drum, and the inner ring is fixed to the tree.

Le cadre de l'invention est défini par les revendications annexées.The scope of the invention is defined by the appended claims.

Brève description des dessinsBrief description of the drawings

D'autres détails apparaîtront plus clairement à la lecture de la description qui suit, faite en référence au dessin annexé, dans lequel les figures 1 à 5 montrent en coupe différentes variantes de l'invention.Other details will appear more clearly on reading the description which follows, made with reference to the appended drawing, in which the Figures 1 to 5 show in section different variants of the invention.

Mode(s) de réalisation de l'inventionMode (s) of realization of the invention

On a représenté sur la figure 1, une platine 10 portant les éléments essentiels d'un mouvement d'horlogerie, dont seul l'accumulateur d'énergie est représenté. Celui-ci est constitué, de manière conventionnelle, d'un barillet 12 comportant un arbre 14 doté de moyens de pivotement sur la platine 10. Le corps de l'arbre 14 définit une bonde 16 munie d'un crochet non représenté.We have shown on the figure 1 , a plate 10 carrying the essential elements of a clockwork movement, of which only the energy accumulator is shown. This is conventionally constituted by a barrel 12 having a shaft 14 provided with pivoting means on the plate 10. The body of the shaft 14 defines a bung 16 provided with a not shown hook.

Un tambour 20 est traversé en son centre par l'arbre 14. Le tambour est muni d'une denture extérieure 22 pour entraîner un rouage d'une montre. Il comprend un fond 23 et des parois latérales formant son diamètre qui définissent un logement. Un dégagement est opéré à l'intérieur des parois latérales. Le tambour 20 est libre de pivoter par rapport à l'arbre 14.A drum 20 is traversed at its center by the shaft 14. The drum is provided with an external toothing 22 for driving a watchwheel. It comprises a bottom 23 and side walls forming its diameter which define a housing. A clearance is made inside the side walls. The drum 20 is free to pivot relative to the shaft 14.

Un ressort lame 24 est disposé dans le logement, fixé par une première extrémité au crochet et par une deuxième extrémité au tambour, au niveau du dégagement.A leaf spring 24 is disposed in the housing, fixed at one end to the hook and at a second end to the drum at the clearance.

Un couvercle 28 ferme le tambour 20. Il est également traversé par l'arbre 14 en son centre, l'arbre et le couvercle étant libres l'un en référence à l'autre.A cover 28 closes the drum 20. It is also traversed by the shaft 14 at its center, the shaft and the cover being free one with reference to the other.

Une roue à rochet 30 est montée solidaire de l'arbre 14, par exemple au moyen d'une vis 32. Cette roue est destinée à être entraînée par des moyens de remontage connus de l'homme du métier afin d'armer le ressort lame.A ratchet wheel 30 is mounted integral with the shaft 14, for example by means of a screw 32. This wheel is intended to be driven by winding means known to those skilled in the art to arm the leaf spring .

Un pont de barillet 33 est monté rigidement sur la platine, pour permettre le pivotement de l'arbre 14. La roue à rochet 30 surmonte le pont 33 et est vissée dans l'arbre 14. Elle pourrait également être disposée à l'autre extrémité de l'arbre 14.A barrel bridge 33 is rigidly mounted on the plate, to allow pivoting of the shaft 14. The ratchet wheel 30 overcomes the bridge 33 and is screwed into the shaft 14. It could also be disposed at the other end of the tree 14.

Selon un aspect important de l'invention, le fond du tambour 23 est situé du côté du pont de barillet 33. Ainsi, le tambour 20 est pivoté via son fond 23 sur le pont de barillet 33 au moyen d'un roulement à billes 34. Selon le mode de réalisation illustré sur la figure 1, ce roulement comprend :

  • une bague intermédiaire 36 fixée au pont de barillet 33, par exemple par vissage comme montré sur la figure, et
  • une bague extérieure 38 rendue solidaire du fond 23 du tambour, par vissage également comme montrés sur la figure, et
  • une bague intérieure 42 rendue solidaire de l'arbre 14, par exemple par chassage ou par vissage.
According to an important aspect of the invention, the bottom of the drum 23 is located on the side of the barrel bridge 33. Thus, the drum 20 is pivoted via its bottom 23 on the barrel bridge 33 by means of a ball bearing 34 According to the embodiment illustrated on the figure 1 , this bearing includes:
  • an intermediate ring 36 fixed to the barrel bridge 33, for example by screwing as shown in the figure, and
  • an outer ring 38 made integral with the bottom 23 of the drum, also by screwing as shown in the figure, and
  • an inner ring 42 secured to the shaft 14, for example by driving or by screwing.

Avantageusement le fond 23 peut présenter une légère surépaisseur afin de le renforcer au niveau du passage des vis. De plus, cette surépaisseur permet de définir un léger jeu entre le fond 23 et les autres éléments du roulement, évitant tout frottement superflu. La tête des vis fixant la bague intermédiaire peut prendre place dans une noyure 40 ménagée dans le pont de barillet 33.Advantageously the bottom 23 may have a slight extra thickness to strengthen it at the passage of the screws. In addition, this extra thickness makes it possible to define a slight clearance between the bottom 23 and the other elements of the bearing, avoiding any superfluous friction. The head of the screws fixing the intermediate ring can take place in a recess 40 formed in the barrel bridge 33.

Le roulement 34 comprend donc une bague intérieure 42 munie d'un trou central circulaire, dans lequel l'arbre 14 est destiné à prendre place. Les bagues du roulement sont conformées de manière à présenter des surfaces de roulement pour les billes, sans qu'il soit besoin de le détailler ici. Des anneaux peuvent compléter les bagues afin de parfaitement définir le chemin de roulement des billesThe bearing 34 thus comprises an inner ring 42 provided with a circular central hole, in which the shaft 14 is intended to take place. The bearing rings are shaped to have bearing surfaces for the balls, without the need to detail it here. Rings can complete the rings to perfectly define the ball raceway

Il est évident que, vu les dimensions d'un barillet 12 de pièce d'horlogerie, les roulements utilisés sont des micro-roulements dont la précision doit être maximale de manière à garantir un positionnement parfait des axes de pivotement et un guidage optimal des éléments en mouvement.It is obvious that, given the dimensions of a cylinder 12 of a timepiece, the bearings used are micro-bearings whose precision must be maximum so as to ensure perfect positioning of the pivot axes and optimal guidance of the elements. moving.

On notera que, selon l'invention, le pont de barillet 33 présente une ouverture pour le libre passage de l'arbre. Vu la présence du roulement tel que décrit ci-dessus, il n'est nul besoin de ménager un palier pour le pivotement de l'arbre au niveau du pont de barillet 33. Un tel palier n'est pas non plus utile au niveau du fond 23.It will be noted that, according to the invention, the barrel bridge 33 has an opening for free passage of the shaft. Given the presence of the bearing as described above, there is no need to provide a bearing for the pivoting of the shaft at the barrel bridge 33. Such a bearing is also not useful in the background 23.

D'autres moyens de guidage périphérique sont également inutiles, ce qui libère toute la place autour du barillet pour d'autres éléments du mouvement. En outre, le fait que la bague intermédiaire 36, qui constitue l'élément de liaison au pont de barillet 33 et donc l'élément de référence pour le pivotement de l'arbre 14 et du tambour 20, soit d'un diamètre relativement important, en tout cas plus important que si ces éléments étaient pivotés directement au niveau de leur axe de pivotement, apporte auxdits éléments une meilleure stabilité et une plus grande précision à leur mouvement. Ceci est bénéfique non seulement pour le pivotement du tambour 20, mais aussi pour celui de l'arbre 14 qui subit beaucoup mieux les contraintes que les arbres de barillet de l'état de la technique également pivotés par un roulement à bille, mais disposé directement au niveau de leur centre. Le rendement obtenu avec un barillet tel que décrit ci-dessus est amélioré sensiblement par rapport aux barillets de l'état de la technique.Other means of peripheral guidance are also useless, which frees all the space around the barrel for other elements of the movement. In addition, the fact that the intermediate ring 36, which constitutes the connecting element to the barrel bridge 33 and therefore the reference element for the pivoting of the shaft 14 and the drum 20, is of a relatively large diameter. in any case more important than if these elements were pivoted directly at their pivot axis, provides said elements a better stability and greater accuracy in their movement. This is beneficial not only for the pivoting of the drum 20, but also for that of the shaft 14 which undergoes much better stresses than the barrel shafts of the state of the art also rotated by a ball bearing, but disposed directly at their center. The yield obtained with a barrel as described above is improved substantially compared to the barrels of the state of the art.

Dans le mode de réalisation illustré à la figure 1, l'arbre de barillet 14 n'est pas monté en porte-à-faux. Son extrémité située du côté de la platine 10 est pivotée par un deuxième roulement à billes 49 agencé dans la platine. De manière classique, ce roulement 49 comprend une première bague extérieure 52 chassée dans la platine et une deuxième bague intérieure 54 solidaire de l'arbre 14.In the embodiment illustrated in figure 1 , the barrel shaft 14 is not mounted cantilevered. Its end located on the side of the plate 10 is pivoted by a second ball bearing 49 arranged in the plate. In a conventional manner, this bearing 49 comprises a first outer ring 52 driven into the plate and a second inner ring 54 integral with the shaft 14.

Selon une première variante illustrée sur la figure 2, le deuxième roulement 49 est directement logé dans le couvercle du tambour 20, ce qui permet de diminuer l'épaisseur de l'ensemble. L'arbre de barillet 14 n'est plus pivoté dans la platine mais pivote en référence au couvercle 28.According to a first variant illustrated on the figure 2 , the second bearing 49 is directly housed in the drum cover 20, which reduces the thickness of the assembly. The barrel shaft 14 is no longer pivoted in the plate but pivots with reference to the lid 28.

Dans une deuxième variante proposée à la figure 3, l'arbre de barillet 14 est monté complètement volant. Autrement dit, l'arbre de barillet n'est pivoté que sur le pont de barillet 33 et ne l'est ni en référence à la platine, ni en référence au couvercle 28 du tambour. L'arbre de barillet peut être raccourci et l'épaisseur du couvercle du barillet peut être réduite, rendant l'ensemble encore plus mince. On pourrait même supprimer totalement le couvercle du barillet. Cette construction est particulièrement avantageuse, car elle permet d'assembler le barillet sur le pont de barillet indépendamment de l'assemblage des autres parties du mouvement. Les opérations de montage du mouvement s'en trouvent facilitées. En outre, il est possible de monter sur le pont et de démonter du pont, soit l'arbre, soit le fond du barillet, sans devoir tout démonter l'ensemble du barillet, à condition que l'ouverture du fond pour le passage de l'arbre soit plus grande que le diamètre extérieur de l'arbre.In a second variant proposed to the figure 3 , the barrel shaft 14 is mounted completely flying. In other words, the barrel shaft is pivoted only on the barrel bridge 33 and is neither in reference to the plate, nor in reference to the lid 28 of the drum. The barrel shaft can be shortened and the thickness of the barrel lid can be reduced, making the whole thing even thinner. We could even completely remove the lid of the barrel. This construction is particularly advantageous because it allows to assemble the barrel on the barrel bridge independently of the assembly of the other parts of the movement. The assembly operations of the movement are facilitated. In addition, it is possible to climb on the bridge and dismount the bridge, either the shaft or the bottom of the barrel, without having to disassemble the entire barrel, provided that the opening of the bottom for the passage of the tree is larger than the outside diameter of the tree.

Bien que les modes de réalisation proposés montrent, pour le roulement 34, que la bague intermédiaire 36 est fixée au pont de barillet 33 et la bague extérieure 38, au fond 23 du barillet, cette construction pourrait être inversée. Ainsi, on pourrait, sans sortir du cadre de l'invention, avoir la bague intermédiaire 36 fixée au fond 23 du barillet et la bague extérieure 38 fixée au pont de barillet 33.Although the proposed embodiments show, for the bearing 34, that the intermediate ring 36 is fixed to the barrel bridge 33 and the outer ring 38 to the bottom 23 of the barrel, this construction could be reversed. Thus, one could, without departing from the scope of the invention, have the ring intermediate 36 fixed to the bottom 23 of the barrel and the outer ring 38 attached to the barrel bridge 33.

Par ailleurs, pour ce qui concerne la variante de la figure 3, on pourrait également envisager de manière avantageuse, de monter le barillet de manière volante sur la platine. On s'est en effet aperçu que, grâce à la stabilité conférée par le roulement tel que proposé par l'invention, il est possible de se dispenser d'un pivotement de l'arbre de barillet par ses deux extrémités. L'arbre de barillet n'est alors pivoté que sur la platine, aucun pivotement n'étant prévu au niveau du couvercle.Moreover, as regards the variant of the figure 3 it could also be advantageous to mount the barrel flying on the plate. It has been found that, thanks to the stability imparted by the bearing as proposed by the invention, it is possible to dispense with a pivoting of the barrel shaft by its two ends. The barrel shaft is then pivoted only on the plate, no pivoting being provided at the lid.

Ainsi, comme proposé à la figure 4, on peut supprimer le pont de barillet et gagner l'épaisseur correspondante. Pour le montage de la roue à rochet 30 sur l'arbre, en l'absence de pont, on peut prévoir une petite entretoise ou un léger épaulement 60 sur l'arbre de barillet pour positionner la roue à rochet en hauteur.Thus, as proposed in figure 4 you can remove the barrel bridge and gain the corresponding thickness. For the mounting of the ratchet wheel 30 on the shaft, in the absence of a bridge, a small spacer or a slight shoulder 60 may be provided on the cylinder shaft to position the ratchet wheel in height.

En adaptant la construction du mouvement, on pourrait aussi monter la roue à rochet 30 côté platine. Sur la figure 5, la roue à rochet est montée sur la face de la platine 10 opposée à celle qui reçoit le barillet. Dans cette variante également, on peut prévoir que la bague intermédiaire 36 est fixée au fond du tambour, et la bague extérieure 38 est fixée à la platine, ou alors que la bague intermédiaire 36 est fixée à la platine, et la bague extérieure 38 fixée au fond.By adapting the construction of the movement, one could also mount the ratchet wheel 30 platinum side. On the figure 5 , the ratchet wheel is mounted on the face of the plate 10 opposite to that which receives the barrel. In this variant also, it can be provided that the intermediate ring 36 is fixed to the bottom of the drum, and the outer ring 38 is fixed to the plate, or while the intermediate ring 36 is fixed to the plate, and the outer ring 38 fixed basically.

Ainsi est proposée une pièce d'horlogerie dont les différents éléments du barillet sont pivotés de manière optimale, tant au niveau du guidage qu'au niveau de la faiblesse des frottements. Ceci est obtenu sans encombrer la platine autour du barillet. En outre, les versions proposées aux figures 3-5, avec l'arbre 14 qui est volant, sont particulièrement avantageuses en termes d'épaisseur et de frottement.Thus is proposed a timepiece whose different elements of the barrel are rotated optimally, both in terms of guiding or the level of weakness of friction. This is achieved without cluttering the platen around the barrel. In addition, the versions proposed to figures 3-5 , with the shaft 14 which is flying, are particularly advantageous in terms of thickness and friction.

La réserve de marche d'un tel barillet est améliorée, grâce à son rendement, supérieur à ceux de l'état de la technique. Il est ainsi possible d'utiliser un ressort moins fort, donc de moindre épaisseur, pour donner l'amplitude voulue au balancier. Le ressort peut donc être enroulé sur un plus grand nombre de tour dans un même volume et donc emmagasiner une plus grande énergie.The power reserve of such a cylinder is improved, thanks to its performance, superior to those of the state of the art. It is thus possible to use a weaker spring, therefore of lesser thickness, to give the desired amplitude to the balance. The spring can be wound on a larger number of turns in the same volume and thus store a greater energy.
