Abstract

The wheel has an adjustment device to adjust its frequency of oscillation and a rim (1) of circular shape free from projections is connected by radial arms (2) to a hub (3). A recess with balance weights (7) having a general U shape by resilient deformation is held in the desired angular position within the corresponding recesses by friction due to the resilience of the weights themselves.

Description

La présente invention a pour objet un balancier pour mouvement d'horlogerie muni d'un dispositif de réglage de son inertie permettant d'ajuster sa fréquence d'oscillation.The present invention relates to a pendulum for movement timepiece equipped with a device for adjusting its inertia to adjust its oscillation frequency.

La plupart des balanciers de ce type comportent des vis de réglage vissées radialement dans la serge du balancier à partir de l'extérieur de celle-ci. Le brevet CH 196.706 décrit un tel balancier. Ces balanciers à vis de réglage radiales présentent des inconvénients qui sont principalement la difficulté de garantir un réglage établi au cours du fonctionnement du mouvement, l'une ou l'autre des vis pouvant se dévisser partiellement ou totalement ; la difficulté d'accès aux vis pour effectuer le réglage de l'inertie du balancier et la friction importante du périmètre du balancier avec l'air, les vis provoquant des turbulences et frictions qui nuisent au bon fonctionnement et à la régularité du balancier.Most rockers of this type have adjusting screws screwed radially into the beam of the beam from the outside thereof. Patent CH 196.706 describes such a balance. These balancers with adjusting screws radial have disadvantages which are mainly the difficulty of guarantee an established setting during the operation of the movement, one or the other screws can be unscrewed partially or completely; the difficulty access to the screws to adjust the inertia of the balance and friction of the perimeter of the balance with the air, the screws causing turbulence and friction which impairs the smooth operation and the regularity of the pendulum.

On connaít encore du brevet GB-845.773 des balanciers présentant dans leur face inférieure des vis de réglage dont la masse est excentrée par rapport à leur axe de rotation. Si le réglage du balancier est facilité par l'accessibilité des vis à partir d'une de ses faces plutôt que par sa périphérie, les vis débordent de la serge du balancier provoquant des turbulences et un freinage nuisant au bon fonctionnement de ce balancier. De plus, il est également difficile d'assurer le positionnement désiré des vis au cours du temps de sorte qu'un déréglage du balancier n'est pas exclu.Patent GB-845,773 discloses pendants presenting in their underside adjusting screws whose mass is eccentric with respect to their axis of rotation. If the adjustment of the balance is facilitated by the accessibility of the screws from one of its faces rather than its periphery, the screws overflow from the balancing serge causing turbulence and braking operation of this pendulum. In addition, it is also difficult to ensure desired positioning of the screws in the course of time so that an adjustment of the pendulum is not excluded.

Du document CH-280.067 on connaít un balancier dont la serge est munie d'évidements débouchant sur sa face supérieure, une goupille étant chassée dans la serge au milieu de chaque évidement. Les masses d'équilibrage sont engagées à force sur ces goupilles et permettent suivant leur orientation angulaire de modifier l'inertie du balancier. Ici également, les évidements débouchent latéralement de la serge et les masses d'équilibrage débouchent hors de celle-ci induisant des perturbations aérodynamiques perturbant la marche du balancier. De plus, l'usinage des évidements et le chassage des goupilles dans la serge sont des opérations délicates et onéreuses.Document CH-280.067 discloses a pendulum whose serge is provided with recesses opening on its upper face, a pin being driven into the serge in the middle of each recess. Balancing weights are engaged force on these pins and allow according to their angular orientation of modify the inertia of the pendulum. Here too, the recesses open laterally of the serge and the balancing masses open out of it inducing aerodynamic disturbances disturbing the progress of the balance. In addition, the machining of the recesses and the driving of the pins in the serge are delicate and expensive operations.

Enfin, on connaít du document CH-125.520 un balancier muni de vis de réglage vissées dans la face supérieure de la serge. Des rondelles peuvent être placées entre la serge et la tête d'une ou plusieurs vis pour assurer le réglage. Dans ce cas, il faut procéder à des taraudages dans la serge et le réglage ne peut se faire que par pas discrets, adjonction d'une ou plusieurs rondelles, ce qui n'est pas suffisamment précis.Finally, it is known from document CH-125.520 a pendulum provided with screws adjustment screwed into the upper face of the serge. Washers can be placed between the serge and the head of one or more screws to ensure adjustment. In this case, it is necessary to make tapping in the serge and the adjustment can not only in discrete steps, adding one or more washers, which is not sufficiently precise.

La présente invention a pour but la réalisation d'un balancier muni d'un dispositif de réglage précis et continu, facile tant à réaliser qu'à régler et ne provoquant qu'un minimum de perturbations aérodynamiques lors du mouvement oscillant du balancier.The object of the present invention is to provide a balance wheel equipped with a precise and continuous adjustment device, easy to realize and adjust causing a minimum of aerodynamic disturbances during the movement oscillating from the pendulum.

La présente invention a pour objet un balancier notamment pour mouvement d'horlogerie muni d'un dispositif de réglage de son inertie pour ajuster sa fréquence qui tend à réaliser les buts énoncés ci-dessus et à obvier aux inconvénients énumérés ci-dessus des dispositifs existants. Le balancier selon l'invention se distingue par les caractéristiques énumérées à la revendication 1.The subject of the present invention is a balance wheel, particularly for watch movement provided with a device for adjusting its inertia to adjust its frequency which tends to achieve the aims stated above and to obviate disadvantages listed above existing devices. The pendulum according to the invention is distinguished by the features listed in claim 1.

Le dessin annexé illustre schématiquement et à titre d'exemple une forme d'exécution du balancier pour mouvement d'horlogerie muni d'un dispositif de réglage selon l'invention.The attached drawing illustrates schematically and by way of example a form of the pendulum for a watch movement equipped with a device for adjustment according to the invention.

La figure 1 est une vue en plan de dessus du balancier selon l'invention.Figure 1 is a top plan view of the beam according to the invention.

La figure 2 en est une coupe suivant la ligne A-A de la figure 1.Figure 2 is a section along the line A-A of Figure 1.

La figure 3 est une vue en perspective partielle à plus grande échelle du balancier.FIG. 3 is a partial perspective view on a larger scale of the balance.

Le balancier pour mouvement d'horlogerie notamment, muni d'un dispositif de réglage de son inertie permettant de régler la fréquence d'oscillation dudit balancier, comporte une serge 1 annulaire, de forme circulaire ou cylindrique droite, reliée par des bras radiaux 2 à un moyeu 3. Dans l'exemple illustré, le balancier comporte quatre bras mais il pourrait en comporter un nombre différent, par exemple deux ou six.The pendulum for a watch movement in particular, provided with a inertia adjustment device for adjusting the oscillation frequency of said balance, comprises an annular serge 1, of circular or cylindrical shape right, connected by radial arms 2 to a hub 3. In the illustrated example, the pendulum has four arms but could have a different number, for example two or six.

Les bras 2 sont de préférence moins épais que la serge 1 comme illustré au dessin. La liaison entre les bras 2 et la serge 1 est réalisée par des courbes continues provoquant le moins possible de perturbations aérodynamiques lors des oscillations du balancier. La serge 1 présente une forme circulaire sans aucune partie saillante, que ce soit dessus, dessous, à l'intérieur ou à l'extérieur de sorte que les perturbations dues au frottement dans l'air lors des mouvements du balancier sont réduites au minimum possible.The arms 2 are preferably less thick than the serge 1 as illustrated to the drawing. The connection between the arms 2 and the serge 1 is made by curves continuous operation causing the least possible aerodynamic disturbance during oscillations of the pendulum. The serge 1 has a circular shape without any protruding part, whether above, below, inside or outside so disturbances due to friction in the air during movements of the pendulum are reduced to the minimum possible.

La serge circulaire 1 présente à ses intersections avec les bras radiaux 2 une plus forte largeur, ce qui permet d'y pratiquer un logement circulaire 4 ouvert sur l'une des faces du balancier, de préférence sa face supérieure 5. Le fond de ce logement 4 est muni d'un trou ou passage traversant 6 débouchant sur l'autre face, la face inférieure de préférence, de la serge 1 du balancier.The circular serge 1 presents at its intersections with the radial arms 2 a greater width, which allows to practice a circular housing 4 open on one of the faces of the balance, preferably its upper face 5. The bottom of this housing 4 is provided with a hole or through passage 6 opening on the other face, the lower face preferably of the serge 1 of the balance.

Ce balancier comporte encore des masselottes de réglage 7 présentant vues en plan la forme générale d'un U, inscrit dans un cercle d'un diamètre correspondant au diamètre des logements 4 ou légèrement supérieur. Ainsi, ces masselottes 7 peuvent être introduites à force dans les logements 4 et sont entièrement noyées dans ces logements, ce qui évite tout frottement avec l'air lors des oscillations du balancier. Lors de cette introduction des masselottes 7 dans les logements, ces masselottes se déforment élastiquement et sont ainsi maintenues par friction dans leur position angulaire dans les logements 4 sous l'effet de l'élasticité propre des masselottes 7.This balance still includes adjusting weights 7 with plan views the general shape of a U, inscribed in a circle of a diameter corresponding to the diameter of the housing 4 or slightly higher. So, these Weights 7 can be forced into housing 4 and are completely embedded in these housings, which avoids any friction with the air when pendulum oscillations. During this introduction of the weights 7 in housing, these weights deform elastically and are thus held by friction in their angular position in the housing 4 sub the effect of the inherent elasticity of the weights 7.

A l'aide d'un outil s'introduisant dans la fente des masselottes 7, il est possible de les faire pivoter dans les logements 4 pour régler l'inertie du balancier. La largeur de la fente 8 des masselottes 7 est inférieure au diamètre du passage 6 de sorte qu'il est possible à l'aide d'un poinçon engagé dans les trous 6 de dégager la masselotte 7 de son logement 4. With the aid of a tool that is introduced into the slot of the flyweights 7, it is possible to rotate in the housing 4 to adjust the inertia of the balance. The width of the slot 8 of the weights 7 is smaller than the diameter of the passage 6 so that it is possible using a punch engaged in holes 6 of disengage the weight 7 from its housing 4.

Le balancier ainsi réalisé ne comporte aucune saillie ni sur sa périphérie externe ou interne ni sur ses faces supérieure ou inférieure, les masselottes 7 étant entièrement noyées dans les logements. Ainsi, la forme extérieure du balancier est simple et continue, lisse et sans aspérités et permet de réduire considérablement les effets du frottement ou de l'écoulement de l'air autour du balancier lors de ses oscillations.The balance thus produced has no projection or on its periphery external or internal or on its upper or lower faces, the weights 7 being completely drowned in the dwellings. Thus, the outer form of the pendulum is simple and continuous, smooth and without asperities and reduces considerably the effects of friction or airflow around the pendulum during his oscillations.

Il est à remarquer que le réglage de la marche diurne de la montre s'effectue en tournant les masselottes sur elles-mêmes dans leur logement 4 dans une plage de réglage de 360°, ce qui fait varier le moment d'inertie du balancier. Quel que soit le réglage, donc la position des masselottes 7, le frottement de l'air provoqué par les oscillations du balancier reste constant et n'influence pas la marche de celui-ci.It should be noted that the adjustment of the daytime running of the watch is done by turning the weights on themselves in their housing 4 in an adjustment range of 360 °, which varies the moment of inertia of the balance. Whatever the adjustment, so the position of the weights 7, the friction of the air caused by pendulum oscillations remains constant and does not influence the walk of it.

L'usinage du balancier est simple et ne nécessite que des perçages et des fraisages. Le réglage de la position des masselottes 7 dans les évidements 4 est aisé car elles sont accessibles depuis la face supérieure du balancier et ne sont fixées dans ces logements que par des forces élastiques de fixation dues à l'élasticité propre de ces masselottes 7.The machining of the balance is simple and only requires holes and millings. The adjustment of the position of the weights 7 in the recesses 4 is easy because they are accessible from the upper face of the pendulum and are not in these receptacles only by elastic fixing forces due to the inherent elasticity of these weights 7.

Le balancier décrit permet donc d'atteindre les buts énoncés et d'obvier aux inconvénients des réalisations antérieures, notamment du fait que ses faces supérieure et inférieure de même que sa périphérie sont lisses et exemptes de saillies et que les masselottes de réglage sont entièrement noyées dans des logements prévus dans la serge.The described pendulum thus makes it possible to reach the stated goals and to obviate disadvantages of previous achievements, in particular the fact that its superior and inferior as well as its periphery are smooth and free of protrusions and that the adjustment weights are fully embedded in housing provided in the serge.
