Definitions

  • the invention relates to an oscillating system for watch movements, as well as to a watch movement.
  • Oscillating systems for mechanical watch movements typically comprise a balance, said balance typically comprising a balance rim.
  • Balances are generally made as follows: The balance rim is first manufactured as a turned part in a cap. A bore is then made in the center of the turned part. This is then typically used for centering, p. ex. to be able to cut rays. It goes without saying that this centering has a certain play, which means that the spokes are not perfectly centered, an imbalance being thus generated in the balance.
  • the cap typically deforms slightly upon separation of the rod (which typically takes the form of a rod of raw material having a diameter of 14mm and a length of 3m, e.g.) from the rod. is the undercut produced by the material stresses exerted for different thicknesses. In the end, the fact that the balance rim must be produced at least in part by turning causes a certain imbalance of the balance due to the manufacture.
  • Oscillating systems for mechanical watches typically further include a hairspring.
  • the required balance springs are typically made from a rod, most often drawn.
  • the diameter of an initial material is reduced from about 30 cm to about 6 mm, and then brought to the required mass, often to a thickness of only 0.03 to 0.04 mm (with a manufacturing tolerance tenth 1/1000 mm) for a height of 0.10 to 0.20 mm, before the characteristic spiral shape is given after heat treatment and cut to the required length by means of a tool winding several of these bands in a drum.
  • the hairspring is subjected to thermal stabilization while it is still in the drum. Very satisfactory homogeneities can be obtained for the production batch by resorting to modern manufacturing methods, however the force distributions vary from one hairspring to another, to which it must be added that the batches are such very different from each other, so that too great inequalities are presented from one lot to another.
  • the balance After balancing the balance, this being required due to the aforementioned imbalance due to the manufacturing conditions, the balance is usually placed on a special machine, which measures the mass inertia of the balance after careful adjustment and automatically sets the class to attribute to the pendulum.
  • the hairspring to be used is cut in the middle, in order to eliminate a hook typically formed on winding, it is placed and compressed on a so-called hairspring roll.
  • the hairspring is then often slightly off-center depending on the type of execution, which has a negative impact on the performance of the watch.
  • the hairspring is then placed on a special machine which again compares the force distribution of the hairspring with a fixed value to decide on the class attributable to it.
  • balance springs and balances of the same class are then assembled together.
  • the error rate is generally quite high if one wishes to obtain a precisely functioning balance.
  • To correct there is a racquet, but its presence is itself a typical cause of problems, and its effectiveness is furthermore limited. Often, it has to be moved too far, and it then negatively influences the isochronism of the watch, in other words the temporally regular oscillation of the balance for different amplitudes.
  • a balance wheel is isochronous if each oscillation is of equal duration, regardless of the amplitude.
  • a so-called double roller is typically still tightened in a complementary manner with a cone on the balance.
  • a small ruby is usually clamped in this double roller to reduce friction and hardness of the material, said ellipse, which is in principle cylindrical, but has a surface on one side. It goes without saying that its installation is not a problem-free operation, nor is the clamping of the double roller.
  • the force exerted by the cog of the mechanical watch movement is typically transmitted to the balance by means of said escapement.
  • the force is in particular typically transmitted by means of two rubies from the last wheel of the cog, the so-called escape wheel, to the balance by through an ellipse.
  • the exhaust is typically made of steel, to achieve the required hardness, and is therefore relatively heavy.
  • the fixing of the rubies, of said pallets is also typically problematic, the positioning and especially the isogonality being particularly delicate.
  • the geometry of the pallets is limited for manufacturing reasons.
  • the document CH-22362-A describes a balance for an oscillating system for a watch movement.
  • the balance does not have a balance rim and is essentially made up of a metal blade or bar comprising a central part and two wings.
  • the central part has an axis bore, and each of the wings has a mass element fixed to the wing by fixing means.
  • the document EP-2874019 discloses an oscillating system for a watch movement, comprising a balance, a hairspring and a fastening element for fixing the hairspring to the balance.
  • the invention aims to overcome or limit the aforementioned state of the art.
  • the invention aims in particular to provide an oscillating system for a mechanical watch movement, of simple construction, easy and economical to manufacture, while ensuring as precise operation as possible of the mechanical watch movement.
  • the invention is based on the observation that the presence of a balance rim particularly complicates the manufacturing process of the oscillating system, among other things because material stresses are formed during required manufacturing steps, particularly during turning, which generate imbalances in the pendulum. These imbalances must then be compensated relatively costly.
  • the invention solves this problem in principle by dispensing with the balance rim, which, although being a component of the watchmaking tradition, makes the manufacture of oscillating systems more delicate.
  • the balance is substantially strip-shaped or substantially cruciform.
  • the use of the terms platinum, platinum support, balance board or balance is irrelevant here, but for reasons of simplicity, we will prefer to use the word balance.
  • Such shapes for the balance have the advantage - unlike a balance with a conventional balance rim - of allowing easy manufacture, in particular with methods generating few constraints.
  • a very large number of manufacturing methods are in principle suitable for the manufacture of the balance, with the exception of turning.
  • the balance is preferably manufactured by cutting and / or laser cutting and / or water jet cutting and / or LIGA machining, and / or by additive manufacturing or by growth or by means of a combination of these techniques.
  • the balance can be produced by any process suitable for machining inserts.
  • the balance comprises a central part and at least two first wings.
  • the first wings are typically arranged around the central part being spaced 180 ° apart, in other words are exactly opposite on either side of the central part.
  • the central part has an axis bore and each of the first wings has a fixing bore for fixing a respective one of the at least two ground elements.
  • the fixing bores are in this case advantageously formed at the ends of the wings, in other words on the sides of the wings remote from the central part.
  • each of the first two wings has a longitudinal slot.
  • Such longitudinal slots make it possible to save material in a particularly simple manner at the level of the first wings, the mass of the latter being reduced in the region of the longitudinal slots. Such mass reductions have an advantageous impact on the operation of the oscillating system, stabilizing the oscillation behavior.
  • said longitudinal slots improve the torsional rigidity of the plate.
  • the oscillating system comprises a fixing element for fixing the hairspring to the balance.
  • a fixing element for fixing the hairspring to the balance.
  • the fixing element is in the form of a pin, the balance, in in particular the central part, preferably comprising a pin sleeve for housing the fixing element.
  • This configuration has the advantage of allowing particularly easy manufacture and assembly.
  • the pin is preferably brazed to the hairspring and fitted into the pin sleeve.
  • the pin sleeve is preferably emerging and preferably produced as a bore.
  • the pin sleeve can also be simply replaced by an opening in the balance, arranged to receive the pin.
  • the oscillating system comprises a lever element.
  • a lever element has the advantage of allowing a particularly easy connection to the escapement of the mechanical watch movement.
  • An alternative to the lever element could be a corresponding configuration of the exhaust and / or of a double roller.
  • the lever element is produced as an impulse pin, more particularly as a lever ellipse, and very advantageously as a cylinder with a partial ellipse of the lever, the plate, in particular the central part, comprising preferably a lever sleeve for housing the lever element or more simply an opening arranged to receive the lever.
  • the impulse pin is preferably fitted by compression in the lever sleeve.
  • the lever sleeve is preferably produced so that it opens out, in other words it passes through the plate over its entire thickness.
  • Such an arrangement of the impulse pin and of the lever sleeve has the advantage of ensuring horizontality between the lever element and the escapement in a particularly simple manner.
  • the axle comprises a single roller, which is preferably designed to function as an integrated safety roller and / or to limit movement of a safety blade.
  • a single roller which is preferably designed to function as an integrated safety roller and / or to limit movement of a safety blade.
  • the axle has a first segment, a second segment, a third segment and two bearing segments, each of the bearing segments preferably having a first partial bearing segment and a second partial bearing segment.
  • a configuration of the axis is particularly advantageous, since it facilitates manufacturing and minimizes manufacturing tolerances.
  • the clearance in height thus has less impact on the manufacturing tolerances, since the elimination of the double roller means that only one dimension has to be respected. The elimination of the double roll also minimizes the risk of material deformation.
  • the single roller has a recess, in particular a lateral recess, shaped so as to function as an integrated safety roller and / or to limit the movement of a safety blade of the mechanical watch movement.
  • This recess is preferably made in the form of an elliptical arc. The presence of such a simple roller is advantageous since it simplifies the construction of the oscillating system.
  • the hairspring has a concentric part and an Archimedean screw part, the concentric part being included at least in part inside the Archimedean screw part. This is advantageous in that satisfactory centering of the hairspring is thus obtained in a simple manner, which helps to minimize balance errors.
  • the balance comprises at least two second wings.
  • the second wings are preferably arranged around the central part in an alternating manner with the first wings, in particular with an angular spacing of 90 °, so as to form a substantially cruciform balance.
  • the presence of two second wings in addition to the first two wings has the advantage of allowing additional adjustment possibilities for the oscillating system. This is particularly advantageous if no racket is provided in the oscillating system.
  • each of the second wings comprises an elbow element, each elbow element preferably having an elbow bore for accommodating an adjusting screw.
  • This has the advantage of simply allowing additional adjustment possibilities for the oscillating system.
  • two elbow bores are provided in each elbow element so that two adjustment screws can be tightened in each elbow element, in particular a large adjustment screw and a small adjustment screw.
  • the presence of two adjustment screws has the advantage of allowing the compensation of more important class differences than if only one adjustment screw were presented per elbow element.
  • the use of standard hairspring of relatively simple construction will thus also be made possible, and / or the manufacturing tolerances may be less restrictive for the hairspring used.
  • the elbow element can be produced by folding or using a square, which allows easy production at a controlled cost.
  • each bent element has a slot provided to cooperate with the bent bore to allow secure clamping of the adjusting screw in the bent bore.
  • Each elbow element advantageously comprises two adjustment screws, two elbow bores and two slots. It is particularly advantageous that one of the adjustment screws of each elbow element is longer than the other, the large adjustment screw advantageously being made as a ground screw and the small adjustment screw being advantageously made as an adjustment screw. It is particularly advantageous that the large adjustment screw is at least partially made of gold and / or that the small adjustment screw is at least partially made of copper or a copper alloy, in particular CuBe.
  • the bent element has an angle of 90 °. This makes it possible to offer an oscillating system with great ease of use and a simplified design.
  • the elbow element has an angle of 45 °, which allows an improvement in the accessibility of the adjustment screw, during the balancing of the assembly, in particular if an adjustment adjustment proves to be necessary .
  • the hairspring is non-metallic, which eliminates the need for magnetism on a part sensitive to its effects.
  • a watch movement according to the invention comprises an oscillating system according to claim 1. It is advantageous that an escapement of the watch movement and / or an escape wheel of the watch movement are made of ruby. This has a positive impact on the mass of the mechanical watch movement and the friction conditions presented therein.
  • This method of adjusting the oscillation frequency of an oscillating system starts with the selection of a hairspring rather than the selection of a balance, which makes it possible to have a more flexible method of use, because a hairspring is not easy to modify while it is easier to change the balance and / or to select other mass elements. This thus makes it possible to overcome a prejudice of the person skilled in the art who is used to having a large stock of components, and to start with the selection of a balance.
  • the selection will relate to a non-metallic hairspring, which makes it possible to preserve the hairspring from ambient magnetism during operation. Choosing a non-metallic hairspring makes it even more advantageous to select it first because of the increased difficulty in modification.
  • At least one of the two mass elements is an adjustment screw
  • the method further comprises a step of adjusting the adjustment screw in order to adjust the balancing of the oscillating system, which provides a great deal of flexibility and ease of implementation of the oscillation frequency adjustment method, in order to obtain the desired oscillation frequency.
  • the oscillating system comprises only two mass elements, it is preferable to choose either two identical mass elements or two adjustment screws, in order to preserve the balance of the assembly.
