Description

La présente invention se rapporte au domaine de l'horlogerie mécanique. Elle concerne, plus particulièrement, une roue d'un mécanisme d'échappement du type recevant de l'énergie d'un ressort-moteur et entraínant un balancier au moyen d'une ancre munie de palettes. La roue d'échappement est munie de dents agencées pour coopérer avec les palettes de l'ancre.The present invention relates to the field of mechanical watchmaking. She more particularly, a wheel of an exhaust mechanism of the type receiving energy from a mainspring and driving a pendulum at means of an anchor provided with pallets. The escape wheel is equipped with teeth arranged to cooperate with the pallets of the anchor.

L'interaction entre les palettes et les dents de la roue d'échappement engendre des frottements. Sans lubrification de la zone de contact entre ces pièces, celles-ci s'usent prématurément. De plus, le rendement de l'échappement en est sensiblement affecté.The interaction between the vanes and the teeth of the escape wheel generates friction. Without lubrication of the contact area between these parts, they wear out prematurely. In addition, the performance of the exhaust is substantially affected.

Le problème de la lubrification est particulièrement difficile à résoudre. En effet, l'huile utilisée doit être stable, notamment résister à l'oxydation et aux écarts de température et, surtout, rester sur la zone de contact sans se répandre sur la roue. En effet, les forces en jeu étant très faibles, il est nécessaire que l'huile soit fluide. Or, les chocs lors des impulsions sont importants. Il y a donc un important risque que l'huile se disperse et se répande sur la roue, voire jusque dans les engrenages, ce qui est fort préjudiciable.The problem of lubrication is particularly difficult to solve. In In fact, the oil used must be stable, in particular withstand oxidation and temperature differences and, above all, stay on the contact area without spread on the wheel. As the forces involved are very weak, it is necessary that the oil be fluid. But shocks during impulses are important. There is therefore a significant risk that the oil will disperse and become spread on the wheel, even in the gears, which is strong detrimental.

Une des solutions habituellement utilisée pour résoudre ce problème est présentée sur les figures 1a et 1b. Les dents 6 de la roue d'échappement se terminent en un plan biseauté 8 formant un angle obtus avec le plan de la roue. L'huile déposée sur le plan 8 y adhère et s'étale, grâce à des phénomènes de tension de surface, sur l'extrémité 9 de la dent qui définit la zone de contact avec les palettes de l'ancre.One of the solutions usually used to solve this problem is shown in Figures 1a and 1b. The teeth 6 of the escape wheel end in a beveled plane 8 forming an obtuse angle with the plane of the wheel. The oil deposited on the plane 8 adheres to it and spreads, thanks to surface tension phenomena, on the end 9 of the tooth which defines the contact area with the pallets of the anchor.

La présente invention a pour but d'améliorer la circonscription du lubrifiant à la zone de contact de la roue d'échappement et des palettes de l'ancre et, surtout, de simplifier la réalisation de la roue.The present invention aims to improve the lubricant constituency at the contact area of the escape wheel and pallets of the anchor and, above all, to simplify the realization of the wheel.

De façon plus précise, l'invention concerne une roue d'échappement dont le sens de rotation définit une direction amont et une direction avale, destinée à prendre place dans un mécanisme d'échappement et formée d'un moyeu, d'une serge montée sur le moyeu et de dents disposées radialement sur ladite serge, lesdites dents présentant une racine terminée par un doigt.More specifically, the invention relates to an escape wheel whose direction of rotation defines an upstream direction and a downstream direction, intended for take place in an exhaust mechanism and formed of a hub, a serge mounted on the hub and teeth arranged radially on said serge, said teeth having a root terminated by a finger.

Selon l'invention, le doigt comporte une première partie d'épaisseur E située du côté de la serge et une deuxième partie, d'épaisseur e inférieure, située du côté de l'extrémité du doigt, la frontière entre ces deux parties définissant un seuil qui forme un huilier, avec la face de la deuxième partie qui lui est attenante.According to the invention, the finger has a first portion of thickness E located on the side of the serge and a second portion, of lower thickness e , located on the side of the end of the finger, the boundary between these two parts defining a threshold which forms an oiler, with the face of the second part which is adjacent to it.

Avantageusement, l'épaisseur de la deuxième partie est sensiblement égale à la moitié de celle de la première partie.Advantageously, the thickness of the second portion is substantially equal to half of that of the first part.

La distance entre le seuil et l'extrémité de la dent est sensiblement égale à l'épaisseur de la roue.The distance between the threshold and the end of the tooth is substantially equal to the thickness of the wheel.

La roue présente encore l'une ou l'autre des caractéristiques suivantes :

  • la paroi du huilier que forme ledit seuil est concave,
  • la paroi du huilier présente des solutions de continuité,
  • la deuxième partie comporte une cavité pratiquée dans son épaisseur, et
  • la deuxième partie porte un appendice s'étendant dans l'épaisseur de la roue
The wheel still has one or more of the following characteristics:
  • the wall of the oiler that forms said threshold is concave,
  • the wall of the oiler presents solutions of continuity,
  • the second part has a cavity made in its thickness, and
  • the second part carries an appendage extending in the thickness of the wheel

D'autres caractéristiques de l'invention apparaítront plus clairement à la lecture de la description qui suit, faite en référence au dessin annexé dans lequel :

  • la figure 2 est une vue de dessus d'une roue d'échappement, et
  • les figures 3a, 3b, 4, 5, 6 et 7 sont des vues agrandies de dents de la roue d'échappement selon différents modes de réalisation de l'invention.
Other characteristics of the invention will appear more clearly on reading the description which follows, made with reference to the appended drawing in which:
  • FIG. 2 is a view from above of an escape wheel, and
  • Figures 3a, 3b, 4, 5, 6 and 7 are enlarged views of teeth of the escape wheel according to different embodiments of the invention.

On a représenté sur la figure 2 une roue d'échappement 10 formée d'un moyeu 12, de quatre bras 14 coplanaires et de même longueur et disposés orthogonalement sur le moyeu 12, d'une serge 16 tenue par les bras 14 et de dents 18, typiquement au nombre de vingt, situées à la périphérie de la roue, dans la continuité de la serge 16. Les dimensions de la roue varient selon le calibre dans lequel elle est utilisée.FIG. 2 shows an escape wheel 10 formed of a hub 12, four arms 14 coplanar and the same length and arranged orthogonally on the hub 12, a serge 16 held by the arms 14 and teeth 18, typically twenty in number, located on the periphery of the wheel, in the continuity of the serge 16. The dimensions of the wheel vary according to the caliber in which it is used.

La roue d'échappement illustrée sur la figure 2 travaille en tournant dans le sens des aiguilles d'une montre. Ce sens de rotation définit, pour chaque dent, un côté amont orienté vers l'avancé de la roue et un côté aval.The escape wheel illustrated in Figure 2 works by turning in the clockwise. This sense of rotation defines for each tooth, an upstream facing side of the wheel and a downstream side.

Dans un mécanisme d'échappement à ancre suisse qui est, de loin, le plus largement utilisé, les dents 18 présentent une racine triangulaire 20 (figure 3a) dont l'extrémité est tronquée et remplacée par un doigt 22 formé d'une base 23 et d'un bec 24. Plus précisément, le bec 24 présente, du côté amont, une partie 25 alignée avec le bord de la base 23 et, du côté aval, un biseau 26 se prolongeant par une partie droite 28, parallèle à la partie 25.In a Swiss lever escapement mechanism that is, by far, the most widely used, the teeth 18 have a triangular root 20 (Figure 3a) whose end is truncated and replaced by a finger 22 formed of a base 23 and a spout 24. More precisely, the spout 24 has, on the upstream side, a portion 25 aligned with the edge of the base 23 and, on the downstream side, a bevel 26 is extending by a straight portion 28, parallel to the portion 25.

Selon l'invention, et comme le montre la figure 3b, le doigt 22 comporte une première partie 22a située du côté de la serge 16 et de même épaisseur qu'elle, et une deuxième partie 22b, d'épaisseur inférieure, située du côté de l'extrémité du doigt. La frontière entre ces deux parties définit un seuil 22c. Typiquement, l'épaisseur de la partie 22a est de 0,15 mm, celle de la partie 22b est de 0.08mm.According to the invention, and as shown in FIG. 3b, the finger 22 comprises a first part 22a located on the side of the serge 16 and of the same thickness it, and a second part 22b, of lower thickness, situated on the side of the end of the finger. The boundary between these two parts defines a threshold 22c. Typically, the thickness of the portion 22a is 0.15 mm, that of the portion 22b is 0.08mm.

La deuxième partie 22b et le seuil 22c forment un espace limité assurant une fonction d'huilier. De la sorte, l'espace destiné à assurer la rétention de l'huile est bien défini. La quantité de lubrifiant disponible peut ainsi être augmentée sans risque de contamination. De plus, cet espace retient le lubrifiant lors du choc de la roue d'échappement contre la palette, en fin d'impulsion.The second part 22b and the threshold 22c form a limited space ensuring a function of oiler. In this way, the space intended to ensure the retention of the oil is well defined. The quantity of lubricant available can thus be increased without risk of contamination. In addition, this space retains the lubricant during shock of the escape wheel against the pallet, at the end of the impulse.

Dans une première variante illustrée sur la figure 3, le seuil 22c forme une paroi concave qui relie, selon une courbe en quart de cercle, un point A situé, côté aval, à la jonction de la base 23 et du biseau 26, et un point B situé côté amont de la base 23.In a first variant illustrated in FIG. 3, the threshold 22c forms a concave wall which connects, in a quarter-circle curve, a point A situated, downstream side, at the junction of the base 23 and the bevel 26, and a point B located upstream of the base 23.

Dans une deuxième variante présentée à la figure 4, le seuil 22c est parallèle à l'extrémité de la dent 18 et passe par un point C situé sur le biseau 26. In a second variant shown in FIG. 4, the threshold 22c is parallel to the end of the tooth 18 and passes through a point C situated on the bevel 26.

Selon une troisième variante (figure 5), le seuil 22c relie un point D situé du côté amont sur la base 23, et un point E situé du côté aval selon une ligne sensiblement tangente à un cercle passant par le centre de la roue.According to a third variant (FIG. 5), the threshold 22c connects a point D located on the upstream side to the base 23, and a point E located on the downstream side along a line substantially tangent to a circle passing through the center of the wheel.

La figure 6 montre une quatrième variante dans laquelle le seuil 22c définit un espace concave qui relie un point F situé à la jonction de la base 23 et du biseau 26, et un point G situé à la même distance de l'extrémité du doigt 22 que le point F. FIG. 6 shows a fourth variant in which the threshold 22c defines a concave space which connects a point F located at the junction of the base 23 and the bevel 26, and a point G situated at the same distance from the end of the finger 22 than point F.

Enfin, la figure 7 illustre encore une autre variante de l'invention. Le seuil 22c relie un point H situé à la jonction du biseau 26 et de la partie droite 28 qui termine le bec 24, et un point I situé à la même distance de l'extrémité du doigt 22 que le point H. Entre ces deux points, le seuil 22c forme trois vagues concaves et partage la largeur du doigt 22 en trois logements identiques. La paroi formée par le seuil 22c présente ainsi des solutions de continuité, qui améliorent encore la rétention de l'huile.Finally, Figure 7 illustrates yet another variant of the invention. The threshold 22c connects a point H located at the junction of the bevel 26 and the right portion 28 which terminates the spout 24, and a point I located at the same distance from the end of the finger 22 as the point H. Between these two points, the threshold 22c forms three concave waves and shares the width of the finger 22 in three identical housings. The wall formed by the threshold 22c thus has continuity solutions, which further improve the retention of the oil.

Pour assurer la lubrification de l'échappement, on place généralement une goutte d'huile sur le plan d'impulsion de la palette d'entrée de l'ancre, cette dernière étant arrêtée. Lorsque l'échappement se met à fonctionner, une partie de l'huile est transférée de la palette sur chacune des dents de la roue, et de là sur la palette de sortie. Très rapidement, l'huile se répartit donc de manière régulière entre les différentes parties de l'échappement.To ensure the lubrication of the exhaust, we generally place a drop of oil on the impulse plane of the anchor inlet pallet, this last being stopped. When the exhaust starts to run, a part of the oil is transferred from the pallet to each of the teeth of the wheel, and from there on the exit pallet. Very quickly, the oil is distributed regularly between the different parts of the exhaust.

Le lubrifiant déposé sur la partie inférieure 22b du doigt 22 a une tension de surface telle qu'il peut s'étaler sur l'extrémité du bec 24, particulièrement sur la zone de contact avec les palettes de l'ancre, alors que la hauteur et la forme du seuil 22c l'empêchent de se répandre sur la roue d'échappement et dans le mouvement de la montre. La partie inférieure 22a et le seuil 22c forment ainsi un huilier, partie intégrante de chacune des dents de la roue 10.The lubricant deposited on the lower part 22b of the finger 22 has a tension of surface such that it can spread over the end of the spout 24, particularly on the contact area with the pallets of the anchor, while the height and shape the threshold 22c prevent it from spilling on the escape wheel and in the movement of the watch. The lower part 22a and the threshold 22c thus form a cruet, an integral part of each of the teeth of the wheel 10.

De manière à encore augmenter la surface de rétention du lubrifiant, la partie d'épaisseur inférieure 22b peut encore comporter une cavité ou un appendice tel qu'un tenon ou une goupille. In order to further increase the retention surface of the lubricant, the part of lower thickness 22b may further comprise a cavity or an appendix such as a pin or a pin.

Bien entendu, les exemples qui viennent d'être donnés ne limitent pas la portée de l'invention et le seuil 22c peut être réalisé de nombreuses autres manières.Of course, the examples that have just been given do not limit the scope of the invention and the threshold 22c can be achieved many other ways.

Une telle roue d'échappement peut être fabriquée de manière particulièrement simple, fiable et précise, par exemple par électroformage.Such an escape wheel can be manufactured particularly simple, reliable and accurate, for example by electroforming.
