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 billes. 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, in order to improve the pivoting quality of the barrel, to mount 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.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.

On connaît également du document JP11174162 la possibilité de monter le barillet au moyen d'un premier roulement à billes interposé entre le tambour et l'arbre du barillet, et un deuxième roulement à billes interposée entre l'arbre et la platine. L'encombrement de ce dispositif n'est pas des plus satisfaisantes.Document is also known JP11174162 the possibility of mounting the barrel by means of a first ball bearing interposed between the drum and the shaft of the barrel, and a second ball bearing interposed between the shaft and the plate. The size of this device is not very satisfactory.

La présente invention a pour but non seulement de pallier ces inconvénients, mais aussi d'améliorer le pivotement du barillet.The present invention aims not only to overcome these disadvantages, but also to improve the pivoting of the barrel.

Divulgation de l'inventionDisclosure of the invention

De façon plus précise, selon l'invention, le tambour de barillet est pivoté par un premier roulement à billes dont une bague est solidaire de la platine et une autre bague est solidaire du fond du tambour. Cette autre bague étant placée sur la face dudit fond côté platine.More specifically, according to the invention, the barrel drum is pivoted by a first ball bearing, one ring is integral with the plate and another ring is secured to the bottom of the drum. This other ring being placed on the face of said platinum side bottom.

Avantageusement, l'arbre de barillet est pivoté dans la platine au moyen d'un deuxième roulement à billes.Advantageously, the barrel shaft is pivoted in the plate by means of a second ball bearing.

Selon un mode de réalisation préféré, l'arbre de barillet et le tambour sont montés pivotants par rapport à la platine au moyen d'un roulement à billes comprenant une bague intermédiaire fixée à la platine, une bague intérieure solidaire de l'arbre et une bague extérieure solidaire du fond du tambour.According to a preferred embodiment, the barrel shaft and the drum are pivotally mounted relative to the plate by means of a ball bearing comprising an intermediate ring fixed to the plate, an inner ring integral with the shaft and a outer ring secured to the bottom of the drum.

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 monté sur la platine 10 et comporte 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 18.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 of a cylinder 12 mounted on the plate 10 and comprises a shaft 14 provided with pivoting means on the plate 10. The body of the shaft 14 defines a bung 16 provided with a hook 18.

Un tambour 20 est traversé en son centre par l'arbre 14 et, selon un aspect important de la présente invention qui sera détaillé ci-après, est pivoté sur la platine 10. Le tambour est muni d'une denture extérieure 22 pour entraîner un rouage d'une montre. Il comprend un fond situé du côté de la platine et des parois latérales formant son diamètre qui définissent un logement 24. Un dégagement 26 est opéré à l'intérieur des parois latérales. Le tambour 20 est libre de pivoter par rapport à l'arbre 14 et il peut constituer un palier pour ce dernier.A drum 20 is traversed at its center by the shaft 14 and, according to an important aspect of the present invention which will be detailed below, is pivoted on the plate 10. The drum is provided with an external toothing 22 to cause a clockwork. It comprises a bottom located on the side of the plate and side walls forming its diameter which define a housing 24. A clearance 26 is operated inside the side walls. The drum 20 is free to pivot relative to the shaft 14 and may constitute a bearing for the latter.

Un ressort lame, non visible au dessin, est disposé dans le logement 24, fixé par une première extrémité au crochet 18 et par une deuxième extrémité au tambour, au niveau du dégagement 26.A leaf spring, not visible in the drawing, is disposed in the housing 24, fixed by a first end to the hook 18 and by a second end to the drum, at the clearance 26.

Un couvercle 28 ferme le tambour 20. Il est également traversé par l'arbre 14 en son centre et peut constituer un palier pour ce dernier.A lid 28 closes the drum 20. It is also traversed by the shaft 14 at its center and may constitute a bearing for the latter.

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 .

Particulièrement à l'invention, le tambour 20 est pivoté sur la platine 10 au moyen d'un roulement à billes 34. Selon le mode de réalisation préféré illustré sur la figure 1, ce roulement comprend :

  • une bague intermédiaire 36 fixée à la platine, par exemple par vissage, et
  • une bague extérieure 38 rendue solidaire du fond tambour, par exemple par vissage également.
Particularly to the invention, the drum 20 is pivoted on the plate 10 by means of a ball bearing 34. According to the preferred embodiment illustrated in FIG. figure 1 , this bearing includes:
  • an intermediate ring 36 fixed to the plate, for example by screwing, and
  • an outer ring 38 secured to the drum bottom, for example also by screwing.

Dans ce mode de réalisation préféré, les moyens de pivotement de l'arbre 14 sur la platine 10 sont également constitués d'un roulement à billes 40, comprenant une première bague intérieure 42 rendue solidaire de l'arbre, par exemple par chassage et une deuxième bague 44 (visible sur les figures 5 et 6) solidaire de la platine 10. Avantageusement, la deuxième bague du roulement par lequel l'arbre pivote est constituée par la bague intermédiaire 36.In this preferred embodiment, the pivoting means of the shaft 14 on the plate 10 also consist of a ball bearing 40, comprising a first inner ring 42 secured to the shaft, for example by driving and a second ring 44 (visible on the figures 5 and 6 ) Advantageously, the second ring of the bearing through which the shaft pivots is constituted by the intermediate ring 36.

De la sorte, l'arbre de barillet 14 et le tambour 20 sont montés pivotants par rapport à la platine au moyen d'un roulement à billes comprenant une bague intermédiaire 36 fixée à la platine, une bague intérieure 42 solidaire de l'arbre et une bague extérieure 38 solidaire du fond du tambour. Avantageusement le fond du tambour 20 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 du barillet 12 et les autres éléments du roulement, évitant tout frottement superflu.In this way, the barrel shaft 14 and the drum 20 are pivotally mounted relative to the plate by means of a ball bearing comprising an intermediate ring 36 fixed to the plate, an inner ring 42 integral with the shaft and an outer ring 38 secured to the bottom of the drum. Advantageously, the bottom of the drum 20 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 of the barrel 12 and the other elements of the bearing, avoiding any superfluous friction.

Un exemple de roulement utilisé est particulièrement visible sur la figure 2. Il définit un plan général. Dans le passage suivant, le côté inférieur du roulement est disposé côté platine 10 sur la figure 1 et son côté supérieur est orienté du côté de la roue à rochet 30.An example of a bearing used is particularly visible on the figure 2 . It defines a general plan. In the following passage, the lower side of the bearing is arranged platinum side 10 on the figure 1 and its upper side is oriented towards the ratchet wheel 30.

Le roulement comprend donc une bague intérieure 42 munie d'un trou central circulaire, dans lequel l'arbre 14 est destiné à prendre place. La bague intérieure 42 présente un pied 42a s'étendant au niveau inférieur de sa paroi extérieure, dans le plan général du roulement. L'extrémité de ce pied 42a est conformée de manière à présenter une surface de roulement pour les billes.The bearing thus comprises an inner ring 42 provided with a circular central hole, in which the shaft 14 is intended to take place. The inner ring 42 has a foot 42a extending at the lower level of its outer wall, in the general plane of the bearing. The end of this foot 42a is shaped so as to have a rolling surface for the balls.

La bague intermédiaire 36 comprend une première gorge 36a parallèle au plan général du roulement, disposée sur la paroi intérieure, sensiblement au milieu de son épaisseur. Elle présente également un pied 36b s'étendant du côté supérieur de sa paroi extérieure, dans le plan général du roulement. La gorge 36a est conformée de manière à former un chemin de roulement, tandis que le pied 36b présente une surface de roulement pour les billes. Les gorges sont typiquement en forme de V. La bague 36 est traversée par des trous 46 pour permettre sa fixation à la platine 10.The intermediate ring 36 comprises a first groove 36a parallel to the general plane of the bearing, disposed on the inner wall, substantially in the middle of its thickness. It also has a foot 36b extending from the upper side of its outer wall, in the general plane of the bearing. The groove 36a is shaped to form a raceway, while the foot 36b has a rolling surface for the balls. The grooves are typically V-shaped. The ring 36 is traversed by holes 46 to allow its attachment to the plate 10.

La bague extérieure 38 comprend une deuxième gorge 38a parallèle au plan général du roulement, disposée sur la paroi intérieure, sensiblement au milieu de son épaisseur. La gorge 38a est conformée de manière à former un chemin de roulement pour les billes, elle est typiquement en forme de V. La paroi extérieure est cylindrique et épouse une creusure de forme adaptée, ménagée dans la platine 10. La bague 38 est traversée par des trous 46 pour permettre sa fixation au tambour 20.The outer ring 38 comprises a second groove 38a parallel to the general plane of the bearing, disposed on the inner wall, substantially in the middle of its thickness. The groove 38a is shaped so as to form a raceway for the balls, it is typically V-shaped. The outer wall is cylindrical and matches a recess of suitable shape, formed in the plate 10. The ring 38 is traversed by holes 46 to allow its attachment to the drum 20.

Des anneaux 48 sont agencés, respectivement, sur la bague intérieure 42 et sur la bague intermédiaire 36, en regard de leur pied, de manière à former avec eux un chemin de roulement pour les billes. Les anneaux 48 sont chassés et soudés aux bagues après la mise en place des billes, assurant en outre le maintien de l'ensemble.Rings 48 are arranged, respectively, on the inner ring 42 and the intermediate ring 36, opposite their foot, so as to form with them a raceway for the balls. The rings 48 are driven and welded to the rings after the placement of the balls, further ensuring the maintenance of all.

Bien entendu, les pieds et les gorges peuvent être inversés. C'est-à-dire que la bague intérieure peut présenter une gorge sur sa paroi extérieure, la paroi intérieure de la bague intermédiaire présentant alors un pied coopérant avec un anneau, etc...Of course, the feet and throats can be reversed. That is to say that the inner ring may have a groove on its outer wall, the inner wall of the intermediate ring then having a foot cooperating with a ring, etc.

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. Ces micro-roulements sont, par exemple, produits par la société Micro Precision System AG.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. These micro-bearings are, for example, produced by the company Micro Precision System AG.

Pivoter le tambour de barillet 20 de la sorte permet de le positionner de manière excellente et d'obtenir des conditions de pivotement n'engendrant que peu de frottement. De plus, il n'est nul besoin de moyen de guidage périphérique, 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 à la platine 10 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.Rotating the barrel drum 20 in this way makes it possible to position it in an excellent manner and to obtain pivoting conditions that generate little friction. In addition, there is no need for guiding means peripheral, 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 plate 10 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 rotated directly at their pivot axis, provides said elements with 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, l'arbre de barillet 14 n'est pas monté en porte-à-faux afin d'améliorer la précision de son positionnement. Son extrémité située du côté opposé à la platine est pivotée par un troisième roulement à billes 49 agencé au moyen d'un pont d'arbre 50, vissé sur la platine. De manière classique, ce roulement 49 comprend une première bague extérieure 52 chassée dans le pont 50 et une deuxième bague intérieure 54 solidaire de l'arbre 14. La roue à rochet 30 surmonte le roulement 49 et le pont 50 et est vissée dans l'arbre 14. Elle pourrait également être disposée à l'autre extrémité de l'arbre 14.In the illustrated embodiment, the barrel shaft 14 is not cantilevered to improve the accuracy of its positioning. Its end located on the opposite side to the plate is pivoted by a third ball bearing 49 arranged by means of a shaft bridge 50, screwed onto the plate. In a conventional manner, this bearing 49 comprises a first outer ring 52 driven into the bridge 50 and a second inner ring 54 integral with the shaft 14. The ratchet wheel 30 overcomes the bearing 49 and the bridge 50 and is screwed into the shaft 14. It could also be disposed at the other end of the shaft 14.

Selon une première variante illustrée sur la figure 3, le troisième roulement 49 est directement logé dans le couvercle du barillet, ce qui permet de faire l'économie du pont 50, diminuant ainsi l'épaisseur de l'ensemble.According to a first variant illustrated on the figure 3 , the third bearing 49 is directly housed in the cylinder cover, which saves the bridge 50, thus reducing the thickness of the assembly.

Selon trois autres variantes illustrées sur les figures 4, 5 et 6, les moyens de pivotement de l'arbre sur la platine et ceux du tambour sur la platine sont indépendants. L'arbre est pivoté par un roulement à billes 40 (figure 4 et 5) ou par un pivotement conventionnel (figure 6), au moyen d'une pierre 54. Le roulement 34 par lequel le tambour 20 est pivoté sur la platine 10 peut alors être fixé à celle-ci par sa bague intérieure 36 (figure 4) ou par sa bague extérieure 38. Le fond du tambour est respectivement fixé à la bague extérieure 38 (figure 4) ou à la bague intérieure 36 du roulement.According to three other variants illustrated on the figures 4 , 5 and 6 , the pivoting means of the shaft on the plate and those of the drum on the plate are independent. The shaft is pivoted by a ball bearing 40 ( figure 4 and 5 ) or by conventional pivoting ( figure 6 ), by means of a stone 54. The bearing 34 by which the drum 20 is pivoted on the plate 10 can then be fixed thereto by its inner ring 36 ( figure 4 ) or by its outer ring 38. The bottom of the drum is respectively fixed to the outer ring 38 ( figure 4 ) or the inner ring 36 of the bearing.

Dans une variante supplémentaire, représentée à la figure 7, le tambour 20 et l'arbre 14 sont pivotés au moyen d'un seul roulement comportant trois bagues 36, 42 et 38, comme dans le mode de réalisation préféré, mais le fond du tambour est solidaire de la bague intermédiaire 36, tandis que la bague extérieure 38 est fixée à la platine 10. Avantageusement, cette bague extérieure 38 est chassée dans une creusure de la platine prévue à cet effet.In a further variant, represented in figure 7 , the drum 20 and the shaft 14 are pivoted by means of a single bearing comprising three rings 36, 42 and 38, as in the preferred embodiment, but the bottom of the drum is secured to the intermediate ring 36, while the outer ring 38 is fixed to the plate 10. Advantageously, this outer ring 38 is driven into a recess of the plate provided for this purpose.

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 et permet même, selon le mode de réalisation choisi, de ne pas utiliser de pont pour le barillet ou la roue à rochet.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 encumbering the platen around the barrel and even allows, according to the embodiment chosen, not to use a bridge for the barrel or the ratchet wheel.

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.
