Definitions
- the present invention relates to a coupling device between a mechanical energy source and an electrical energy generator in a timepiece comprising a shaft driven by said mechanical energy source and a cylindrical element fixedly and coaxially mounted on this tree.
- Such a coupling device is known from US Pat. No. 4,644,246 for supplying current, in particular a timepiece.
- the latter comprises an AC generator, a rechargeable battery and a charging system interposed between the generator and the battery, the generator comprising a multipolar rotor carrying permanent magnets and a stator provided with windings delivering the AC current.
- An eccentric mass drives the rotor.
- the rotor, stator and ground are mounted coaxially.
- the coupling between the mass, source of mechanical energy, and the rotor of the electric power generator is carried out, at least in one described embodiment, by a spiral spring one end of which is attached to a cylindrical element making part of the pivot shaft of the eccentric mass, the other end of which is attached to a cage carrying the generator rotor.
- the rotor In the idle state, the rotor is magnetically retained by the stator, which constitutes a certain positioning torque.
- the mass tends or winds the spiral spring around the cylindrical element until the energy accumulated by the spring exceeds the positioning energy of the rotor relative to the stator. From this moment, the rotor is released and rotated at high speed until the kinetic energy stored by the spring, the generator then producing a high electromotive force to charge the battery.
- the present invention is characterized in that said cylindrical element is surmounted by a tube mounted to rotate freely around said shaft and arranged to drive said generator, a helical spring being adjusted with fatty friction on the cylindrical element and on the tube by its first and last turns respectively, a space being provided between said tube and cylindrical element and the central turns of said spring.
- the coupling device 1 fits between a source of mechanical energy 2 and a generator of electrical energy 3 as seen in FIG. 1.
- the source of mechanical energy 2 is an eccentric oscillating weight of the type found on mechanical self-winding watches.
- the electric power generator 3 is made up of a magnetic rotor 33 carried by a shaft 27. By turning, the rotor produces variations in magnetic flux on a winding 34 disposed in a casing 40 for flux return.
- the casing is fixed in a plate 32 of the watch.
- the AC alternating current collected at the terminals of the coil 34 is intended to charge an accumulator of the gold cap type for example, and this via a conventional rectifier. In turn the accumulator will power a quartz oscillator, a frequency divider and a stepping motor as is well known in electronic watches.
- the oscillating weight is driven by a bidirectional movement which must be made unidirectional to wind a barrel spring.
- this oscillating mass pivots in the center of the movement and coaxially with the switch and is supported by a ball bearing, a part 41 of which is represented in FIG. 1.
- To this mass is linked a wheel 30 whose teeth are engaged with a first pawl wheel 13.
- the wheel 30 also meshes on a second pawl wheel 14 as shown in dotted lines in FIG. 2.
- the first pawl wheel 13 (see FIGS. 1 and 2) cooperates with a first driving disc 50 driven out a shaft 4 driving the coupling device 1 according to the invention.
- the second pawl wheel 14 (see dotted representation of FIG.
- FIG. 2 shows that on the shaft 4 driven as we saw above, is mounted fixedly and coaxially, by driving for example , a cylindrical element 5.
- the cylindrical element 5 is surmounted by a tube 6 arranged to rotate freely around the shaft 4.
- the freedom of the tube 6 is ensured by two stones 23 and 24 driven into the tube and whose hole center is freely adjusted on the shaft 4 which is arranged to drive the generator 3 ( Figure 1).
- a helical spring 7 is adjusted with fatty friction on the cylindrical element 5 and on the tube 6 by its first 8 and last 9 turns respectively.
- FIG. 2 also shows that a space 10 is provided between the tube and cylindrical element and the central turns 11 that the spring 7 presents.
- the generator 3 is driven by a wheel 15 of large diameter.
- This wheel is integral with the tube 6.
- the teeth 26 of this wheel 15 are engaged with a pinion 25 carried by the shaft 27 of the generator 3.
- the shaft 4 of the coupling device pivots between stage 32 of the movement and a bridge 31 carried by this movement.
- the operation of the coupling device is as follows:
- the shaft 4 When the shaft 4 rotates (unidirectionally as mentioned above), it drives the first turns 8 of the spring 7, tightened with fatty friction around the cylindrical element 5 and wound in a direction which tends to tighten this friction even more , to shoot with him.
- the last turns 9 of the spring 7 wound with fatty friction on this tube are further tightened around it, which has the consequence of tensioning the spring 7 in its central turns 11 which contract and decrease in diameter to thus accumulate the energy developed by the source of mechanical energy from the oscillating mass.
- the torque stored by the spring 7 exceeds the positioning torque of the generator 3, the latter starts to rotate at high speed, driven as it is by the wheel 15 secured to the tube 6.
- the generator will rotate until exhaust the potential energy stored in the spring 7, then will continue its race for a few more laps because, as of this exhaustion, the spring 7 tends to slip at the place of the first and last turns 8 and 9, which allows the generator 3 further releasing the kinetic energy acquired by its rotor 33.
- This device shows that not only is it free of shocks (the spring 7 is not fixed anywhere) thereby giving it a long service life, but also that it is capable of restoring the energy which has was conferred almost entirely, since yields of the order of 98% could be measured. It is in fact a very advantageous device allowing on the one hand the clutch and the disengagement between a source of mechanical energy and a generator of electrical energy and on the other hand the almost total restitution of energy stored by the mechanical energy source.
- the proposed device also makes it possible to transform the relatively slow speed of the mechanical energy source (approximately 240 revolutions / minute) into a very rapid speed (approximately 15,000 revolutions / minute) which is favorable to the overall efficiency of the generator.
- the strong multiplication of speed generated by the ratio between the number of teeth of the pinion 25 of the generator shaft and the number of teeth 26 of the big wheel uniting with the device of the invention contributes significantly important at this high speed.
- the generator is always driven at the same speed, since it is released only when its positioning torque is less than the mechanical torque stored by the spring. This has the advantage of ensuring a constant output, the generator always restoring the same amount of energy.
- the helical spring has central turns 11 whose diameter is larger than the diameter of the first and last turns 8 and 9, these first and last turns having a substantially equal diameter. Therefore the outer diameter 16 of the tube 6 and the outer diameter 18 of the cylindrical member 5 are also substantially the same. This way we simplify the way of making the spring 7.
- the tube 6 is stepped according to at least two different diameters, the first 16 receiving the last turns 9 of the spring 7 and the second 17, smaller penetrating at least partially inside the cylindrical element 5 shaped into a cup, the outside diameter 18 of said cup receiving the first turns 8 of the spring 7.
- a spring 7 of constant diameter from top to bottom since a space 10 would be always formed between the lower part 45 of the tube 6 and the central turns 11 of the spring 7.

Description
La présente invention est relative à un dispositif de couplage entre une source d'énergie mécanique et une génératrice d'énergie électrique dans une pièce d'horlogerie comportant un arbre entraîné par ladite source d'énergie mécanique et un élément cylindrique monté fixement et coaxialement sur cet arbre.The present invention relates to a coupling device between a mechanical energy source and an electrical energy generator in a timepiece comprising a shaft driven by said mechanical energy source and a cylindrical element fixedly and coaxially mounted on this tree.
Un tel dispositif de couplage est connu du brevet US-A-4 644 246 pour alimenter en courant notamment une pièce d'horlogerie. Cette dernière comporte une génératrice AC, une batterie rechargeable et un système de charge interposé entre la génératrice et la batterie, la génératrice comportant un rotor multipolaire portant des aimants permanents et un stator pourvu d'enroulements délivrant le courant AC. Une masse excentrique entraîne le rotor. Le rotor, le stator et la masse sont montés coaxialement. Le couplage entre la masse, source d'énergie mécanique, et le rotor de la génératrice d'énergie électrique est réalisé, au moins dans un mode d'exécution décrit, par un ressort spiral dont une des extrémités est attachée à un élément cylindrique faisant partie de l'arbre de pivotement de la masse excentrique et dont l'autre des extrémités est attachée à une cage portant le rotor de la génératrice. A l'état de repos, le rotor est retenu magnétiquement par le stator, ce qui constitue un certain couple de positionnement. Quand la masse commence à tourner, elle tend ou enroule le ressort spiral autour de l'élément cylindrique jusqu'à ce que l'énergie accumulée par le ressort dépasse l'énergie de positionnement du rotor par rapport au stator. A partir de ce moment, le rotor est libéré et pivoté à vitesse rapide jusqu'à épuisement de l'énergie cinétique emmagasiné par le ressort, la génératrice produisant alors une force électromotrice élevée pour charger la batterie.Such a coupling device is known from US Pat. No. 4,644,246 for supplying current, in particular a timepiece. The latter comprises an AC generator, a rechargeable battery and a charging system interposed between the generator and the battery, the generator comprising a multipolar rotor carrying permanent magnets and a stator provided with windings delivering the AC current. An eccentric mass drives the rotor. The rotor, stator and ground are mounted coaxially. The coupling between the mass, source of mechanical energy, and the rotor of the electric power generator is carried out, at least in one described embodiment, by a spiral spring one end of which is attached to a cylindrical element making part of the pivot shaft of the eccentric mass, the other end of which is attached to a cage carrying the generator rotor. In the idle state, the rotor is magnetically retained by the stator, which constitutes a certain positioning torque. When the mass begins to rotate, it tends or winds the spiral spring around the cylindrical element until the energy accumulated by the spring exceeds the positioning energy of the rotor relative to the stator. From this moment, the rotor is released and rotated at high speed until the kinetic energy stored by the spring, the generator then producing a high electromotive force to charge the battery.
Pour astucieuse qu'elle soit, la solution proposée ci-dessus présente cependant plusieurs inconvénients. D'abord le système est soumis incessamment à des chocs répétés. Le ressort spiral, soudé d'une part à l'élément cylindrique et d'autre part à la cage supportant le rotor de la génératrice, est sollicité tant au début de l'armage de ressort (démarrage brusque de la masse excentrique), qu'à la fin du déroulement du même ressort (arrêt brusque du rotor quand le ressort s'est complètement déroulé). Ces phénomènes fatiguent fortement les attaches intérieure et extérieure du ressort spiral pour les amener rapidement à se casser. D'autre part, on a constaté qu'une fois l'énergie emmagasiné par le ressort a été entièrement restituée au rotor, c'est-à-dire lorsque le ressort est entièrement déroulé, le rotor s'arrête brusquement de tourner, alors qu'il pourrait continuer de tourner sur sa lancée et restituer ainsi sa propre énergie cinétique.However clever it may be, the above solution has several drawbacks. First, the system is constantly subjected to repeated shocks. The spiral spring, welded on the one hand to the cylindrical element and on the other hand to the cage supporting the rotor of the generator, is stressed both at the start of the spring winding (sudden start of the eccentric mass), that '' at the end of the unwinding of the same spring (sudden stop of the rotor when the spring has completely unwound). These phenomena strongly tire the interior and exterior attachments of the spiral spring to quickly cause them to break. On the other hand, it has been found that once the energy stored by the spring has been fully returned to the rotor, that is to say when the spring is fully unwound, the rotor suddenly stops spinning, then that it could continue to turn on its momentum and thus restore its own kinetic energy.
Pour pallier les inconvénients cités, la présente invention est caractérisée en ce que ledit élément cylindrique est surmonté par un tube monté pour tourner librement autour dudit arbre et arrangé pour entraîner ladite génératrice, un ressort hélicoïdal étant ajusté à frottement gras sur l'élément cylindrique et sur le tube par ses premières et dernières spires respectivement, un espace étant ménagé entre lesdits tube et élément cylindrique et les spires centrales dudit ressort.To overcome the aforementioned drawbacks, the present invention is characterized in that said cylindrical element is surmounted by a tube mounted to rotate freely around said shaft and arranged to drive said generator, a helical spring being adjusted with fatty friction on the cylindrical element and on the tube by its first and last turns respectively, a space being provided between said tube and cylindrical element and the central turns of said spring.
L'invention sera comprise maintenant à la lecture de la description suivante donnée à titre d'exemple et illustrée par le dessin dans lequel :
- la figure 1 est une coupe partielle dans un mécanisme utilisant le dispositif de couplage selon l'invention, et
- la figure 2 est une coupe du dispositif de couplage proprement dit et selon un mode de réalisation de l'invention.
- FIG. 1 is a partial section in a mechanism using the coupling device according to the invention, and
- Figure 2 is a section of the coupling device itself and according to an embodiment of the invention.
Le dispositif de couplage 1 selon l'invention s'inscrit entre une source d'énergie mécanique 2 et une génératrice d'énergie électrique 3 comme on le voit sur la figure 1. Dans l'exemple choisi, la source d'énergie mécanique 2 est une masse excentrique oscillante du type de celle équipant les montres mécaniques à remontage automatique. Bien sûr que l'invention n'est pas limitée à cette masse particulière, mais pourrait être étendue à d'autres source d'énergie mécanique. La génératrice d'énergie électrique 3 se compose quant à elle d'un rotor aimanté 33 porté par un arbre 27. En tournant, le rotor produit des variations de flux magnétique sur un bobinage 34 disposé dans un carter 40 de retour de flux. Le carter est fixé dans une platine 32 de la montre. Le courant alternatif AC recueilli aux bornes de la bobine 34 est destiné à charger un accumulateur du type gold cap par exemple, et cela via un redresseur classique. A son tour l'accumulateur va alimenter un oscillateur à quartz, un diviseur de fréquence et un moteur pas à pas comme cela est bien connu des montres électroniques.The
Dans les pièces d'horlogerie à remontage automatique la masse oscillante est animée d'un mouvement bidirectionnel qu'il s'agit de rendre unidirectionnel pour remonter un ressort de barillet. Généralement cette masse oscillante pivote au centre du mouvement et coaxialement à l'aiguillage et est supportée par un palier à billes dont une partie 41 est représentée en figure 1. A cette masse est liée une roue 30 dont les dents sont en prise avec une première roue à cliquets 13. La roue 30 engrène également sur une seconde roue à cliquets 14 comme cela est esquissé en pointillés sur la figure 2. La première roue à cliquet 13 (voir figures 1 et 2) coopère avec un premier disque entraîneur 50 chassé sur un arbre 4 entraînant le dispositif de couplage 1 selon l'invention. La seconde roue à cliquets 14 (voir représentation en pointillé de la figure 2) coopère avec un second disque entraîneur 51 en prise directe sur le premier disque 50. Dans ce système, quand la masse entraînant la roue 30 tourne dans un sens, c'est la première roue à cliquet 13 qui entraîne le premier disque 50 dans un sens horaire, alors que si cette masse tourne dans l'autre sens, c'est la seconde roue à cliquet 14 qui entraîne le second disque 51 dans un sens antihoraire, ce second disque 51 faisant tourner à son tour le premier disque 50 dans un sens horaire. Ainsi l'arbre 4 tourne-t-il toujours dans le même sens quelque soit le sens de rotation de la masse 2. Ce système est bien connu de l'état de la technique et le lecteur qui voudrait en savoir plus lira avec profit l'ouvrage de B. Humbert intitulé : "La montre suisse à remontage automatique" Edition Scriptar, Lausanne 1955, pages 198 à 202.In self-winding timepieces, the oscillating weight is driven by a bidirectional movement which must be made unidirectional to wind a barrel spring. Generally this oscillating mass pivots in the center of the movement and coaxially with the switch and is supported by a ball bearing, a
Si l'on revient maintenant à l'invention proprement dite, illustrée à plus grande échelle en figure 2, on aperçoit que sur l'arbre 4 entraîné comme on l'a vu plus haut, est monté fixement et coaxialement, par chassage par exemple, un élément cylindrique 5. L'élément cylindrique 5 est surmonté d'un tube 6 arrangé pour tourner librement autour de l'arbre 4. La liberté du tube 6 est assurée par deux pierres 23 et 24 chassées dans le tube et dont le trou central est ajusté librement sur l'arbre 4 qui est arrangé pour entraîner la génératrice 3 (figure 1). Comme le montre bien la figure 2, un ressort hélicoïdal 7 est ajusté à frottement gras sur l'élément cylindrique 5 et sur le tube 6 par ses premières 8 et dernières 9 spires respectivement. La figure 2 montre encore qu'un espace 10 est ménagé entre les tube et élément cylindrique et les spires centrales 11 que présente le ressort 7.If we now return to the invention proper, illustrated on a larger scale in Figure 2, we see that on the
Dans l'exemple illustré en figure 2 la génératrice 3 est entraînée par une roue 15 de grand diamètre. Cette roue est solidaire du tube 6. Les dents 26 de cette roue 15 sont en prise avec un pignon 25 porté par l'arbre 27 de la génératrice 3. On voit sur la même figure que l'arbre 4 du dispositif de couplage pivote entre la platine 32 du mouvement et un pont 31 porté par ce mouvement. En fait, le fonctionnement du dispositif de couplage est le suivant :In the example illustrated in FIG. 2, the generator 3 is driven by a
Lorsque l'arbre 4 tourne (unidirectionnellement comme mentionné ci-dessus), il entraîne les premières spires 8 du ressort 7, serrées à frottement gras autour de l'élément cylindrique 5 et enroulées dans un sens qui a tendance à resserrer encore davantage ce frottement, à tourner avec lui. Comme le tube 6 est retenu de tourner par le couple de positionnement magnétique de la génératrice 3, les dernières spires 9 du ressort 7 enroulées à frottement gras sur ce tube se resserrent encore autour de lui, ce qui a pour conséquence de tendre le ressort 7 en ses spires centrales 11 qui se contractent et diminuent de diamètre pour accumuler ainsi l'énergie développée par la source d'énergie mécanique issue de la masse oscillante. Dès que le couple emmagasiné par le ressort 7 dépasse le couple de positionnement de la génératrice 3, cette dernière se met à tourner à grande vitesse, entraînée qu'elle est par la roue 15 solidaire du tube 6. La génératrice va tourner jusqu'à épuiser l'énergie potentielle emmagasinée dans le ressort 7, puis va continuer sa course pendant quelques tours encore car, dès cet épuisement, le ressort 7 a tendance à patiner à l'endroit des premières et dernières spires 8 et 9, ce qui permet à la génératrice 3 de libérer encore l'énergie cinétique acquise par son rotor 33.When the
Ce dispositif fait apparaître que non seulement il est exempt de chocs (le ressort 7 n'est fixé à nulle part) lui impartissant de ce fait une longue durée de vie, mais encore qu'il est capable de restituer l'énergie qui lui a été conférée presque intégralement, puisque des rendements de l'ordre de 98% ont pu être mesurés. Il s'agit en fait d'un dispositif très avantageux permettant d'une part l'embrayage et le débrayage entre une source d'énergie mécanique et une génératrice d'énergie électrique et d'autre part la restitution quasi intégrale de l'énergie emmagasinée par la source d'énergie mécanique.This device shows that not only is it free of shocks (the spring 7 is not fixed anywhere) thereby giving it a long service life, but also that it is capable of restoring the energy which has was conferred almost entirely, since yields of the order of 98% could be measured. It is in fact a very advantageous device allowing on the one hand the clutch and the disengagement between a source of mechanical energy and a generator of electrical energy and on the other hand the almost total restitution of energy stored by the mechanical energy source.
Le dispositif proposé permet également de transformer la vitesse relativement lente de la source d'énergie mécanique (environ 240 tours/minute) en une vitesse très rapide (environ 15'000 tours/minute) ce qui est favorable au rendement global de la génératrice. A noter que la forte multiplication de vitesse engendrée par le rapport entre le nombre de dents du pignon 25 de l'arbre de la génératrice et le nombre de dents 26 de la grande roue faisant bloc avec le dispositif de l'invention, contribue de façon importante à cette vitesse élevée. A noter également que la génératrice est toujours entraînée à la même vitesse, puisqu'elle n'est libérée qu'au moment où son couple de positionnement est inférieur au couple mécanique emmagasiné par le ressort. Ceci a l'avantage d'assurer un rendement constant, la génératrice restituant toujours la même quantité d'énergie.The proposed device also makes it possible to transform the relatively slow speed of the mechanical energy source (approximately 240 revolutions / minute) into a very rapid speed (approximately 15,000 revolutions / minute) which is favorable to the overall efficiency of the generator. Note that the strong multiplication of speed generated by the ratio between the number of teeth of the
Comme on le voit de la figure 2, qui illustre un mode de réalisation de l'invention, le ressort hélicoïdal présente des spires centrales 11 dont le diamètre est plus grand que le diamètre des premières et dernières spires 8 et 9, ces premières et dernières spires présentant un diamètre sensiblement égal. De ce fait le diamètre extérieur 16 du tube 6 et le diamètre extérieur 18 de l'élément cylindrique 5 sont également sensiblement les mêmes. Ce cette façon on simplifie la façon de réaliser le ressort 7.As seen in Figure 2, which illustrates an embodiment of the invention, the helical spring has
Toujours sur la figure 2, on aperçoit que le tube 6 est étagé selon au moins deux diamètres différents, le premier 16 recevant les dernières spires 9 du ressort 7 et le second 17, plus petit pénétrant au moins partiellement à l'intérieur de l'élément cylindrique 5 façonné en forme de coupelle, le diamètre extérieur 18 de ladite coupelle recevant les premières spires 8 du ressort 7. Dans cette disposition à étages, on pourrait imaginer un ressort 7 de diamètre constant du haut en bas puisqu'un espace 10 serait toujours ménagé entre la partie inférieure 45 du tube 6 et les spires centrales 11 du ressort 7.Still in FIG. 2, it can be seen that the
