Description
L'invention concerne un ensemble barillet pour montre mécanique avec diamètre de bonde réduit.The invention relates to a barrel assembly for a mechanical watch with reduced bung diameter.
L'invention concerne encore un mouvement d'horlogerie comportant au moins un tel ensemble barillet.The invention also relates to a watch movement comprising at least one such barrel assembly.
L'invention concerne encore une pièce d'horlogerie comportant au moins un tel mouvement ou/et au moins un tel ensemble barillet.The invention also relates to a timepiece comprising at least one such movement and / or at least one such barrel assembly.
L'invention concerne le domaine de l'horlogerie, et plus particulièrement le domaine des barillets de stockage d'énergie, pour l'alimentation d'un mouvement, d'une sonnerie, ou d'une autre fonctionnalité d'une pièce d'horlogerie.The invention relates to the field of watchmaking, and more particularly the field of energy storage barrels, for feeding a movement, a ring, or other functionality of a room watchmaking.
Pour augmenter la réserve de marche, par augmentation du nombre de tours d'un ressort de barillet, une solution consiste en une diminution du diamètre de l'arbre de barillet et de la bonde associée, de façon à augmenter la place disponible dans le tambour pour le ressort.To increase the power reserve, by increasing the number of turns of a mainspring, one solution consists of a decrease in the diameter of the barrel shaft and the associated bung, so as to increase the space available in the drum. for the spring.
Le rapport du rayon de bonde par rapport à l'épaisseur du ressort est usuellement compris entre 10 et 20, et l'invention se propose d'abaisser ce rapport en-dessous de 10, et préférentiellement dans la plage comprise entre 5 et 10.The ratio of the bead radius to the thickness of the spring is usually between 10 and 20, and the invention proposes to lower this ratio below 10, and preferably in the range between 5 and 10.
Le dimensionnement ne doit pas être fait à la légère, en effet un risque de casse existe sir le diamètre de la bonde est trop faible.Sizing should not be done lightly, indeed a risk of breakage exists if the diameter of the plug is too small.
Dans l'architecture classique des barillets, un rochet est monté axialement sur un axe de barillet ou sur une bonde, par l'intermédiaire d'un carré, le rochet étant généralement fixé par une vis axiale. La dimension de cette vis et celle du carré conditionnent donc un diamètre minimal d'une portée de pivotement. Un épaulement jointif à cette portée de pivotement limite l'ébat axial de l'arbre ou de la bonde par rapport à une platine ou à un pont porteur d'une pierre ou similaire.In the conventional architecture of the barrels, a ratchet is mounted axially on a barrel axis or on a bung, via a square, the ratchet being generally fixed by an axial screw. The size of this screw and that of the square thus condition a minimum diameter of a pivoting surface. A shoulder abutting with this pivoting surface limits axial fretting of the shaft or the bung relative to a plate or bridge carrying a stone or the like.
Un diamètre encore supérieur à celui de cet épaulement est nécessaire pour une portée de guidage en pivotement du tambour sur l'arbre ou sur la bonde, combinée à un épaulement de limitation de l'ébat axial du tambour. Le respect de sections de matière minimales implique une chaîne de cotation qui se traduit par un encombrement conséquent, difficile à réduire. On ne peut en particulier pas se contenter de réduire l'ensemble des dimensionnements, car les sections de matière sont alors insuffisantes pour assurer la tenue en fatigue.A diameter even greater than that of this shoulder is necessary for a pivoting guide surface of the drum on the shaft or on the bung, combined with a shoulder limiting axial fretting of the drum. The respect of minimal sections of matter implies a quotation chain which results in a large size, difficult to reduce. In particular, it is not enough to reduce all the sizing, because the sections of material are then insufficient to ensure fatigue resistance.
Du fait de ces limites physiques au dimensionnement des différents composants, il est nécessaire d'envisager d'autres architectures de barillet que l'architecture classique qui vient d'être décrite.Because of these physical limitations to the dimensioning of the various components, it is necessary to consider other barrel architectures than the conventional architecture that has just been described.
L'invention prend en compte plusieurs solutions pour arriver à cette diminution du diamètre de bonde.The invention takes into account several solutions to achieve this reduction of the bung diameter.
Une contrainte importante est d'assurer la démontabilité de l'ensemble, pour un éventuel échange du ressort de barillet.An important constraint is to ensure the disassembly of the assembly, for a possible exchange of the mainspring.
Les différentes voies proposées par l'invention peuvent être combinées entre elles, pour obtenir un résultat optimal en fonction de l'encombrement disponible, de la position du rochet, de la présence ou non d'un couvercle pour la fermeture du barillet, cette fonction pouvant aussi être dévolue au rochet.The different routes proposed by the invention can be combined with each other, to obtain an optimal result depending on the space available, the position of the ratchet, the presence or absence of a lid for closing the cylinder, this function can also be devolved to the ratchet.
Une première solution consiste à assurer l'ébat entre tambour et couvercle par le ressort de barillet, en reportant sur le ressort cette fonction de réglage d'ébat, en particulier en équipant le ressort de zones saillantes, telles qu'ergots, zones laminées plus larges, bride rapportée, ou similaire. Il est alors possible de supprimer les épaulements d'appui du tambour et du couvercle sur l'arbre de barillet ou sur la bonde.A first solution is to ensure the frolicking between drum and cover by the mainspring, transferring to the spring this frolicking adjustment function, in particular by equipping the spring protruding areas, such as dots, more rolled areas wide, flange reported, or the like. It is then possible to remove the bearing shoulders of the drum and cover on the barrel shaft or on the bung.
Une deuxième solution consiste à réaliser une bonde en plusieurs parties, notamment en deux ou trois parties. Cette solution permet notamment de réaliser une bonde de diamètre inférieur au diamètre de pivotement du tambour. Avantageusement, la bonde est introduite par l'alésage du tambour. Un arbre ou une bonde en deux parties, ou davantage, facilite l'usinage du crochet d'accrochage du coquillon du ressort de barillet.A second solution is to make a bung in several parts, including two or three parts. This solution makes it possible in particular to make a bung of diameter smaller than the pivoting diameter of the drum. Advantageously, the plug is introduced through the bore of the drum. A shaft or a bung in two parts, or more, facilitates the machining of hook of hook of the shell of the mainspring.
La bonde peut comporter, pour l'entraînement du rochet, un carré classique, ou encore un filetage. Ou encore, de façon non limitative, dans une deuxième varianteThe bung may include, for the ratchet drive, a conventional square, or a thread. Or, in a non-limiting way, in a second variant
La bonde peut encore comporter une ou plusieurs rondelles ou bagues de rattrapage de diamètre pour son guidage dans platine et pont.The bung can still include one or more washers or diameter catch rings for its guidance in platinum and bridge.
Une autre solution consiste à chasser sur la bonde une rondelle de réglage de l'ébat tambour-couvercle. Cette bague est montée de façon à éviter, pour une intervention sur le barillet, tout démontage d'un pont.Another solution is to chase on the bung a setting washer of the drum-lid frog. This ring is mounted so as to avoid, for intervention on the barrel, any disassembly of a bridge.
Une autre solution encore consiste à assurer le pivotement dans les ponts pour le tambour ou/et le couvercle, au lieu d'effectuer ce pivotement au niveau de l'arbre de barillet ou de la bonde. Avantageusement, à la fois le tambour et le couvercle sont pivotés dans une platine et un pont.Yet another solution is to provide pivoting in the bridges for the drum and / or the cover, instead of performing this pivoting at the barrel shaft or the plug. Advantageously, both the drum and the lid are pivoted in a plate and a bridge.
Les différentes variantes proposées par l'invention assurent une facilité d'usinage, une facilité de montage, une facilité de démontage, et une maîtrise des débats axiaux entre les différents composants et par rapport aux ponts.The different variants proposed by the invention ensure ease of machining, ease of assembly, ease of disassembly, and control of axial debates between the various components and with respect to the bridges.
