Description

La présente invention se rapporte à un mouvement pour pièce d'horlogerie du type comportant un rouage de finissage, un tourbillon et un bâti définissant un plan de référence, les mobiles du rouage de finissage et le tourbillon pivotant sur le bâti autour d'axes perpendiculaires au plan de référence.The present invention relates to a movement for a timepiece of the a type having a finishing gear, a vortex and a frame defining a reference plane, the wheels of the finishing train and the swirling tourbillon on the frame around axes perpendicular to the reference plane.

Le tourbillon est un dispositif destiné à moyenner la marche dans les positions verticales. Il comprend une cage sur laquelle sont montés pivotants un balancier-spiral et un mobile d'échappement comprenant une roue et un pignon.The whirlpool is a device designed to average walking in positions vertical. It includes a cage on which are pivoted a sprung balance wheel and an escape wheel comprising a wheel and a pinion.

Une roue fixe est disposée sur le bâti de manière à coopérer avec le pignon pour entraíner le mobile d'échappement, lorsque tourne la cage. Cette dernière comporte un pignon ou une roue, appelé ci-après pignon de cage, relié cinématiquement au rouage de finissage de la pièce d'horlogerie, en général à la roue de moyenne.A fixed wheel is disposed on the frame so as to cooperate with the pinion to drive the mobile escape, when turns the cage. This last comprises a pinion or a wheel, hereinafter referred to as a cage gear, kinematically connected to the finishing gear of the timepiece, in general to the average wheel.

Chaque fois que le balancier se trouve en position pour recevoir une impulsion motrice de l'échappement, le couple appliqué par la roue de moyenne sur le pignon de cage fait légèrement tourner la cage, l'impulsion au balancier étant donnée par l'échappement dont le mobile tourne par engrènement de son pignon avec la roue fixe.Whenever the pendulum is in position to receive a driving impulse of the exhaust, the torque applied by the wheel of average on the cage gear slightly rotates the cage, the impulse to pendulum being given by the escapement whose mobile turns by meshing of its pinion with the fixed wheel.

Les mobiles du mouvement sont, en général, agencés et nombrés de manière à ce que le tourbillon effectue un tour par minute. Ainsi, lorsque la pièce d'horlogerie est disposée verticalement, la position du point d'attache du balancier fait un tour par minute, ce qui moyenne les écarts de marche dans les positions verticales.The motions of the movement are, in general, arranged and numbered the vortex performs one revolution per minute. So when the room timepiece is arranged vertically, the position of the point of attachment of the pendulum makes one revolution per minute, which averages the walking differences in vertical positions.

Par contre, le décalage entre positions horizontales et verticales subsiste. Pour pallier cet inconvénient, l'horloger allemand Walter Prendel (Groitzsch, Allemagne) a réalisé une montre de poche dans laquelle l'axe du balancier fait un angle de 30° avec celui de la cage du tourbillon et ceux des autres mobiles de la montre disposés sur le bâti. De la sorte, la position du balancier varie de 30 à 60° au maximum lorsque la montre est soit en position verticale, soit en position horizontale. Pour pouvoir entretenir le mouvement du balancier, les composants de l'échappement sont aussi inclinés, l'angle d'inclinaison allant croissant de la roue d'échappement au balancier. Une telle solution est difficile à maítriser du point de vue technique et les conditions de travail de l'échappement sont peu favorables.On the other hand, the difference between horizontal and vertical positions remains. To overcome this disadvantage, the German watchmaker Walter Prendel (Groitzsch, Germany) has made a pocket watch in which the axis of the pendulum makes an angle of 30 ° with that of the tourbillon cage and those of other mobiles of the watch arranged on the frame. In this way, the position of the pendulum varies from 30 to 60 ° maximum when the watch is in the vertical position or horizontal position. To maintain the movement of the pendulum, the exhaust components are also inclined, the inclination angle from the escape wheel to the balance wheel. Such a solution is difficult to master from a technical point of view and the working conditions of the exhaust are unfavorable.

Pour pallier ces inconvénients, le mouvement de pièce d'horlogerie selon l'invention comporte un bâti définissant un plan de référence, un rouage de finissage, une roue fixe et un tourbillon comprenant une cage qui tourne autour d'un axe AA et sur laquelle sont montés pivotants un balancier-spiral et un mobile d'échappement comprenant une roue et un pignon.To overcome these disadvantages, the timepiece movement according to the invention comprises a frame defining a reference plane, a gear train of finishing, a fixed wheel and a tourbillon comprising a rotating cage around an axis AA and on which are mounted pivoting a balance-spiral and an escape wheel comprising a wheel and a pinion.

Ce mouvement est caractérisé en ce que le balancier et le mobile d'échappement pivotent respectivement autour d'axes BB et CC parallèles entre eux et qui sont en biais par rapport à l'axe de pivotement de la cage.This movement is characterized in that the pendulum and the mobile exhaust respectively pivot about parallel axes BB and CC between them and which are at an angle to the axis of pivoting of the cage.

La cage est avantageusement montée pivotante sur le bâti, alors que la roue fixe, munie d'une denture présentant des flancs, montée rigidement sur le bâti, est disposée de manière à coopérer avec le pignon du mobile d'échappement pour l'entraíner lorsque la cage tourne.The cage is advantageously pivotally mounted on the frame, while the wheel fixed, provided with teeth having flanks, mounted rigidly on the frame, is arranged to cooperate with the pinion of the escapement mobile to drive it when the cage rotates.

Afin d'assurer des frottements aussi faibles que possible, la roue fixe et le pignon du mobile d'échappement sont agencés de manière à former un engrenage dans lequel les flancs de leurs dents, dans leur zone de contact, sont tangents l'un avec l'autre. Ainsi, dans le cas où l'axe du mobile d'échappement coupe l'axe de rotation du tourbillon, il est alors avantageux que la roue fixe et le pignon d'échappement forment ensemble un engrenage conique.In order to ensure as little friction as possible, the fixed wheel and the pinion of the escapement mobile are arranged to form a gear in which the flanks of their teeth, in their contact zone, are tangent to each other. So, in the case where the axis of the mobile exhaust system cuts the axis of rotation of the vortex, it is then advantageous that the fixed wheel and the exhaust pinion together form a gear conical.

Si l'axe du mobile d'échappement ne coupe pas l'axe de la cage et qu'il est tangent à un cylindre dont le rayon est sensiblement égal à la distance séparant le balancier et le mobile d'échappement, il est possible d'obtenir de bonnes conditions d'engrènement avec un pignon d'échappement et une roue fixe formant ensemble un engrenage hélicoïdal. If the axis of the escapement does not cut the axis of the cage and is tangent to a cylinder whose radius is substantially equal to the distance separating the balance and the escapement mobile, it is possible to obtain good meshing conditions with an exhaust pinion and a fixed wheel together forming a helical gear.

De manière avantageuse, la cage comporte deux planches définissant des plans parallèles entre eux et obliques en référence à son axe de pivotement, les axes de pivotement du balancier et du mobile d'échappement étant perpendiculaires aux plans des deux planches.Advantageously, the cage comprises two boards defining planes parallel to each other and oblique with reference to its pivot axis, the pivoting axes of the balance wheel and the escape wheel being perpendicular to the planes of the two planks.

Afin de garantir un balancier de grande dimension, son axe coupe celui de la cage dans la partie médiane comprise entre les deux planches.In order to guarantee a large pendulum, its axis cuts that of the cage in the middle part between the two boards.

Classiquement, l'échappement comporte, en outre, une ancre. Son axe de pivotement est parallèle à celui du balancier et du mobile d'échappement.Conventionally, the escapement comprises, in addition, an anchor. Its axis of pivoting is parallel to that of the balance and the mobile escape.

D'autres avantages et caractéristiques de l'invention ressortiront de la description qui va suivre, faite en regard du dessin annexé, dans lequel :

  • la figure 1 représente, vue en coupe, la partie du mouvement comportant un tourbillon, et
  • la figure 2 montre une partie de tourbillon d'un deuxième mode de réalisation du mouvement selon l'invention.
Other advantages and features of the invention will emerge from the description which follows, given with reference to the appended drawing, in which:
  • FIG. 1 represents, in sectional view, that part of the movement comprising a vortex, and
  • Figure 2 shows a tourbillon portion of a second embodiment of the movement according to the invention.

Le mouvement, dans sa partie représentée sur la figure 1, comprend :

  • un bâti comportant une platine 10 dont la face inférieure 10a définit un plan de référence, et un pont 12 fixé sur la platine 10, lesquels sont munis de pierres formant chacune un palier 14,
  • un tourbillon 16, monté pivotant sur les paliers 14 autour d'un axe AA perpendiculaire au plan de référence,
  • une roue de moyenne 18 montée pivotante sur le bâti autour d'un axe parallèle à l'axe AA, dont seule une portion de la planche est visible au dessin, en tant que partie d'un rouage de finissage ainsi partiellement représenté, et
  • une roue fixe 19 annulaire, à denture conique, montée rigidement sur la platine 10 et entourant le tourbillon 16.
The movement, in its portion shown in FIG. 1, comprises:
  • a frame comprising a plate 10 whose bottom face 10a defines a reference plane, and a bridge 12 fixed on the plate 10, which are provided with stones each forming a bearing 14,
  • a vortex 16, pivotally mounted on the bearings 14 about an axis AA perpendicular to the reference plane,
  • an average wheel 18 pivotally mounted on the frame about an axis parallel to the axis AA, of which only a portion of the board is visible in the drawing, as part of a finishing gear thus partially shown, and
  • an annular fixed wheel 19, with conical teeth, rigidly mounted on the plate 10 and surrounding the vortex 16.

Le tourbillon 16 comporte une cage 20 comprenant deux planches 22 et 24 reliées entre elles par des piliers non visibles au dessin, deux arbres 26 et 28, montés respectivement sur les planches 22 et 24 et munis chacun d'un pivot, identifié par la lettre a, à leur extrémité libre, engagé dans l'un des paliers 14. Les arbres sont fixés sur les planches par des vis schématiquement représentées par des traits d'axe. Il est bien clair que les planches 22 et 24 sont très fortement découpées, de manière à ce que la cage 20 soit la plus légère possible.The vortex 16 comprises a cage 20 comprising two boards 22 and 24 interconnected by pillars not visible in the drawing, two shafts 26 and 28, respectively mounted on the boards 22 and 24 and each provided with a pivot, identified by the letter a , at their free end, engaged in one of the bearings 14. The shafts are fixed on the boards by screws schematically represented by center lines. It is clear that the boards 22 and 24 are very strongly cut, so that the cage 20 is as light as possible.

Les surfaces de contact des arbres contre les planches sont en biais par rapport à l'axe AA, de telle sorte que les planches 22 et 24 sont obliques par rapport à cet axe.The contact surfaces of the trees against the planks are angled by relative to the axis AA, so that the boards 22 and 24 are oblique by report to this axis.

L'arbre 26 est, en outre, muni d'un pignon 26b engrenant avec la roue de moyenne 18.The shaft 26 is furthermore provided with a pinion 26b meshing with the wheel of average 18.

Les planches 22 et 24 sont chacune munies, dans leur partie centrale, d'un logement dans lequel est chassé un chaton 27. Un balancier-spiral 29 est monté pivotant dans ces chatons 27, autour d'un axe BB perpendiculaire aux planches et incliné d'un angle α par rapport à l'axe AA, typiquement compris entre 20 et 45°. Les axes AA et BB se coupent dans l'espace compris entre les deux planches. De la sorte, le balancier peut présenter un diamètre important, malgré le fait qu'il soit incliné par rapport au plan de référence.The boards 22 and 24 are each provided, in their central part, with a housing in which a kitten is hunted 27. A balance-spring 29 is pivoted in these kittens 27, about an axis BB perpendicular to boards and inclined at an angle α with respect to the axis AA, typically included between 20 and 45 °. Axes AA and BB intersect in the space between the two boards. In this way, the balance can have a diameter important, despite being inclined relative to the reference plane.

La planche 22 porte, en outre, un pont 30. Des pierres 32 sont fixées l'une dans le pont 30, l'autre dans la planche 22. Un mobile d'échappement 34, comportant un pignon 34a et une roue 34b, y est monté pivotant. Le pignon 34a est disposé de manière à engrener avec la roue fixe 19. Le mobile d'échappement pivote autour d'un axe CC parallèle à l'axe BB. Sur cette figure, le mobile d'échappement est disposé de manière à ce qu'il coupe l'axe AA, décrivant ainsi un cône dont le sommet se trouve sur l'axe AA et qui forme un angle égal à 2α.The board 22 carries, in addition, a bridge 30. Stones 32 are fixed one in the deck 30, the other in the board 22. An escape wheel 34, comprising a pinion 34a and a wheel 34b, is pivotally mounted thereon. Pinion 34a is arranged to mesh with the fixed wheel 19. The mobile exhaust rotates around a DC axis parallel to the BB axis. On this figure, the escape wheel is arranged so that it cuts the axis AA, thus describing a cone whose summit is on the AA axis and which form an angle equal to 2α.

L'échappement dont est muni le tourbillon est fréquemment de type à ancre suisse. Dans ce cas, le balancier 29 est relié cinématiquement au mobile d'échappement 34 par une ancre qui transforme le mouvement rotatif de la roue en mouvement alternatif. L'ancre n'a pas été représentée sur le dessin pour éviter de le surcharger. Elle pivote entre deux pierres portées l'une par la planche 24, l'autre par un pont supplémentaire non visible au dessin, autour d'un axe parallèle aux axes BB et CC.The escapement with which the tourbillon is equipped is frequently of anchor type Swiss. In this case, the rocker 29 is kinematically connected to the mobile exhaust 34 by an anchor which transforms the rotary movement of the wheel in reciprocating motion. The anchor was not represented on the drawing to avoid overloading it. It pivots between two stones worn one by the board 24, the other by an additional bridge not visible in the drawing, around an axis parallel to the BB and CC axes.

La structure de la roue fixe 19 dépend de la position et de l'orientation du mobile 34 sur la cage. Si son axe CC coupe l'axe AA, comme illustré sur la figure 1, il est avantageux que la roue fixe 19 et le pignon 34a forment ensemble un engrenage conique. La conicité peut être entièrement définie sur le pignon, sur la roue ou répartie entre les deux.The structure of the fixed wheel 19 depends on the position and the orientation of the mobile 34 on the cage. If its DC axis intersects the AA axis, as shown on the 1, it is advantageous that the fixed wheel 19 and the pinion 34a form together a bevel gear. The taper can be fully set on the pinion, on the wheel or distributed between the two.

Si le mobile 34 est disposé de manière à ce que l'axe CC soit tangent à un cylindre d'axe AA dont le rayon est sensiblement égal à la distance comprise entre les axes BB et CC, comme représenté sur la figure 2, alors, cet engrenage est avantageusement de type hélicoïdal.If the mobile 34 is arranged so that the axis CC is tangential to a AA axis cylinder whose radius is substantially equal to the distance between axes BB and CC, as shown in Figure 2, then, this gear is advantageously helical type.

Si le mobile 34 occupe une position intermédiaire, l'engrenage que forment le pignon 34a et la roue fixe 19 présente alors une structure complexe comprise entre ces deux cas de figure. Dans tous les cas, toutefois, il est avantageux que l'engrenage que forment la roue fixe 19 et le pignon 34a du mobile d'échappement soit agencé de manière à ce que les flancs de leurs dents, dans leur zone de contact, soient tangents l'un avec l'autre.If the mobile 34 occupies an intermediate position, the gear that forms the pinion 34a and the fixed wheel 19 then has a complex structure included between these two cases. In any case, however, it is advantageous that the gear that form the fixed wheel 19 and the pinion 34a of the mobile exhaust system is arranged in such a way that the flanks of their teeth, in their contact area, be tangent to each other.

La roue de moyenne 18 et le pignon 26b sont avantageusement nombrés de manière à ce que le tourbillon fasse un tour par minute.The average wheel 18 and the pinion 26b are advantageously numbered so that the vortex makes one revolution per minute.

Durant ce tour et si la pièce d'horlogerie est en position horizontale, le balancier 29 décrira un cône et fera en permanence un angle α par rapport à la verticale. Si elle est en position verticale, l'angle de l'axe BB par rapport à la verticale est compris entre 90°+ α et 90° - α. Plus généralement, quelle que soit la position de la pièce d'horlogerie, jamais l'axe du balancier ne reste dans une position fixe. De la sorte, la marche est mieux moyennée. Par ailleurs, la structure des pièces constitutives reste relativement simple, seuls les arbres 24 et 26 présentant des faces gauches. Par ailleurs, les conditions d'engrènement du pignon 34a et de travail de l'ancre avec la roue d'échappement restent tout à fait normales et de qualité. During this turn and if the timepiece is in a horizontal position, the pendulum 29 will describe a cone and will permanently angle α with respect to the vertical. If it is in a vertical position, the angle of the BB axis relative to the vertical is between 90 ° + α and 90 ° - α. More generally, whatever the position of the timepiece, never the axis of the pendulum remains in a fixed position. In this way, walking is better averaged. By Moreover, the structure of the constituent parts remains relatively simple, only trees 24 and 26 having left faces. Moreover, the conditions meshing pinion 34a and working the anchor with the wheel Exhaust remain completely normal and quality.

II est évident que le mouvement décrit peut faire l'objet de nombreuses variantes, sans pour autant sortir du cadre de l'invention. Le tourbillon pourrait sans autre être de type volant, c'est à dire avec un seul point de pivotement, ou d'un type comportant plusieurs cages, par exemple comme celui décrit dans le document WO03017009.It is obvious that the movement described can be the object of many variants, without departing from the scope of the invention. The whirlpool could without any other flying type, ie with only one pivot point, or of a type comprising several cages, for example as described in WO03017009.

Il est également possible d'agencer le mouvement de manière à ce que le tourbillon tourne sur lui-même plus vite ou plus lentement qu'à raison d'un tour par minute. Il est également envisageable de disposer les planches de la cage perpendiculairement à son axe de pivotement, les paliers du balancier et du mobile d'échappements étant alors inclinés par rapport à ce plan.It is also possible to arrange the movement so that the swirl turns on itself faster or slower than one turn per minute. It is also possible to arrange the boards of the cage perpendicular to its axis of rotation, the bearings of the balance and the mobile exhaust being then inclined relative to this plane.

Dans le mode de réalisation de la figure 1, la conicité de l'engrenage que forment la roue 19 et le pignon 34a est entièrement réalisée sur la roue 19. Il serait également possible d'avoir un pignon 34a conique ou de répartir la conicité entre les deux constituants de l'engrenage.In the embodiment of FIG. 1, the taper of the gear form the wheel 19 and the pinion 34a is entirely made on the wheel 19. would also be possible to have a tapered pinion 34a or to distribute the taper between the two components of the gear.

Les deux modes de réalisation décrits comportent une cage disposée perpendiculairement au plan de référence du mouvement. Il est également possible d'incliner l'axe AA de manière à ce qu'il ne soit pas perpendiculaire au plan de référence. Dans ce cas, les dentures de la roue de moyenne 18 et du pignon 26b sont taillées de manière à former ensemble un engrenage conique.Both embodiments described comprise a cage arranged perpendicular to the reference plane of the movement. he is also possible to tilt the AA axis so that it is not perpendicular to the reference plane. In this case, the teeth of the wheel of average 18 and 26b of the pinion are cut to form together a gear conical.

Ainsi, grâce aux caractéristiques revendiquées, le mouvement selon l'invention présente des avantages remarquables, sans pour autant poser de problèmes techniques industriellement insurmontables.Thus, thanks to the characteristics claimed, the movement according to the invention has remarkable advantages, without industrially insurmountable technical problems.
