Description

Domaine de l'inventionField of the invention

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.

Arrière-plan de l'inventionBackground of the invention

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.

Résumé de l'inventionSummary of the invention

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.

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.

  • puis une deuxième portée de pivotement dans une platine ou un pont dudit mécanisme horloger.
