Definitions

  • the present invention relates to a regulating organ for a mechanical wristwatch.
  • the present invention relates in particular to a regulating organ for a chronograph.
  • Mechanical watches generally comprise a regulating member consisting of a flywheel called pendulum on the axis of which is fixed a spiral spring called spiral.
  • rockers Given the energy available, rockers usually have a high moment of inertia for a low mass; that is to say that their diameter is as large as the volume available, and that the mass is concentrated at the periphery, for example in the serge or in other elements, for example weights.
  • This moment of inertia can also be modified to adjust the watch, either manually with screws, or automatically in the case of bimetallic rockers that deform with the temperature. Involuntary deformations of the balance, for example due to expansion, however, have the effect of disrupting the progress of the watch.
  • the term balance can be defined by its function, unique or in any case principal, which is to increase the inertia of the regulating member to determine, together with the spiral spring, the oscillation frequency of the regulating member.
  • the sprung balance oscillates around its equilibrium position at a frequency that depends mainly on the rigidity of the balance spring and the moment of inertia of the balance.
  • a rocker therefore constitutes a piece mounted on the balance shaft, pivotable with this axis and whose mass is distributed around the axis so as to give the regulating member a greater inertia in rotation.
  • the word "pendulum” in this context indicates a piece whose main function, or even unique, is to accumulate at each oscillation a potential and kinetic energy which is higher, generally much higher, than that accumulated by the axis of the balance around which the oscillation takes place.
  • the potential and kinetic energy accumulated by a balance is greater than or equal to at least 10 times that accumulated by the balance shaft, typically at least 1000 times greater.
  • the balance therefore has a moment of inertia which is greater than or equal to at least 10 times the moment of inertia of the axis, preferably at least 1000 times greater.
  • the moment of inertia of a regulating member is determined by the set of rotating parts, including the balance shaft, the balance, the hub, the plate, the spiral, etc. In conventional regulating devices, this moment of inertia is, however, largely determined by the pendulum alone, which contributes at least 80% to the moment of total inertia of the rotating assembly. Preferably the moment of inertia of the balance represents at least 95% of the moment of inertia of the rotating assembly.
  • the rocker must therefore be distinguished from other elements such as the hub or the dowel plate, whose main function is not to increase the mass or the moment of inertia of the regulating member, whose moment of inertia is generally of the same order as the moment of the balance shaft, and which contribute only a small percentage to the moment of inertia of the rotating assembly
  • the balance serves as flywheel and fills the lack of energy stored in the hairspring during deformation.
  • the pendulum is source of many disturbances, due to inaccuracies of its inertia during its manufacture, dilations, etc.
  • the number of alternations per unit of time determines the temporal resolution of the regulator.
  • a mechanical watch displaying the seconds of the current time must comprise a regulating member performing at least 3,600 vibrations per hour.
  • the usual regulating bodies perform 28,800 or sometimes 36,000 vibrations per hour, which makes it possible to measure the time with a resolution of 0.125 or 0.1 seconds, respectively.
  • the temporal resolution is improved, allowing shorter time intervals to be counted.
  • An improved temporal resolution is especially useful for chronographs, for which a time resolution of the hundredth of a second is sometimes desired.
  • a high oscillation frequency however, generates significant energy losses, especially at the exhaust, which reduces the power reserve of the watch. For this reason, the oscillation frequency chosen is usually a compromise between the resolution requirements of the chronograph and the desire to maintain as high a power reserve as possible for the display of the current time.
  • the usual chronograph watches take the energy necessary for the operation of the chronograph on the kinematic chain linking the barrel to the regulating organ and to the indicators of the watch. As a result, the watch is disturbed when the chronograph is started.
  • the patent application WO03 / 065130 in the name of TAG Heuer SA suggests a construction in which a basic movement intended for the display of the current time is provided with a first barrel and a first regulating organ performing 28,800 oscillations per hour, while an auxiliary chronograph module is provided with a second barrel and a second regulator member performing 360'000 oscillations per hour.
  • This construction makes it possible to produce a chronograph watch capable of measuring the time with a resolution of one hundredth of a second, without affecting the power reserve of the basic movement used for the display of the current time.
  • the two kinematic chains are independent, the start of the chronograph does not affect the precision of the basic movement and the running of the watch.
  • This solution was implemented in TAG Heuer's "Caliber 360" which demonstrated the technical feasibility of the solution.
  • An object of the present invention is to provide a regulating organ for a mechanical wristwatch, in particular a regulating organ for a mechanical chronograph, capable of measuring the time with an improved resolution compared to the prior art.
  • Another object of the invention is to propose a regulating organ for a mechanical wristwatch which makes it possible to measure the time with a resolution of one hundredth or even one thousandth of a second.
  • the claimed regulating member is therefore devoid of any pendulum according to the definition given above, that is to say of any rotary member whose sole or principal function is to increase the moment of inertia of the assembly. rotation, and whose moment of inertia would contribute at least 80% to the moment of inertia of the rotating assembly.
  • This solution also has the advantage of considerably reducing the moment of inertia of the rotating elements on the axis of the spiral, and therefore to increase the frequency of oscillation.
  • FIG. 1 and 2 An embodiment of a regulating member according to one embodiment of the invention is illustrated on the Figures 1 and 2 .
  • This regulating organ is in particular intended to serve as a regulator for the chronograph function of a mechanical chronograph; the same movement may comprise two regulating members on the same plate, or on two separate plates, one of the regulating organs serving to regulate the operation of the watch while the other regulating organ, similar or similar to that described in this application , serves to adjust the operation of the chronograph function.
  • a separate barrel provides the energy required by each regulator member, which avoids disruptions in the operation of the watch when the chronograph is engaged.
  • the power reserve of the second cylinder which indicates the duration that can still be timed before having to recharge the second cylinder, is preferably indicated on the dial by means of a chronograph power reserve indicator.
  • the power reserve of the first barrel charging the first regulator member used for the display of the current time is advantageously indicated separately on the dial by means of a power reserve indicator of the watch.
  • the two barrels can preferably be loaded simultaneously by means of a common winding rod engaging on the two barrels and / or by means of a common oscillating mass.
  • the first barrel is automatically reassembled and the second manually.
  • the two barrels can be raised separately by means of two separate winding rods and / or oscillating masses.
  • one of the barrels (for example the chronograph cylinder) is loaded by the other cylinder manually or automatically remounted; the energy available is distributed between the two barrels.
  • the illustrated regulator comprises a hairspring 1 mounted with a ferrule 5 on a hairspring axis 2.
  • the regulating member is devoid of balance.
  • the regulating organ of the chronograph is sized to oscillate at frequencies never reached before, preferably at a frequency of 3'600'000 vibrations per hour, or 500 Hz.
  • the regulating member comprises in particular an axis 2, which is intended to rotate between two non-represented bearings when the hairspring 1 is stretched and relaxed.
  • a plate 4 mounted on this axis carries the plate pin 40 which collaborates with the horns 60, 65 and with the stinger 61 of an anchor 6 shown in FIGS. Figures 5 and 6 , similar to the more conventional Swiss anchor escapements.
  • the word "plate” therefore designates a part intended to be mounted on the axis of the regulating organ and which comprises an ankle, called a plateau pin, arranged to collaborate with the horns and with the stinger of an anchor .
  • the plate 4 is advantageously made of silicon or ceramic or other material with a lower density than that of the axis 2, in order to reduce its moment of inertia. It is advantageously formed of two disks: the large plate 42 and the small plate 43, interconnected by a gun 45.
  • the small plate may comprise a notch 430 for the dart.
  • a simple tray, with a single disc, can also be used.
  • Axle 2 also carries a hub 3 driven or glued which serves to provide a bearing surface for whip 72 of the launcher, described below in connection with the figure 4 .
  • the axis of the regulating member is thus accelerated almost instantaneously when the pushbutton 75 is engaged so as to communicate a pulse to the hub 3 through the blade 73, the column wheel 74 and the launcher 7.
  • the pressure of the whip 72 on the hub makes it possible to block the hub while maintaining the regulating organ of the chronograph and thus to preserve the position of the chronograph hands.
  • the term "hub” indicates any part intended to be mounted on the balance shaft, pivoting with this axis and cooperating with a spiral spring, which accumulates a potential energy and kinetics weak or comparable to that accumulated by the balance shaft.
  • the potential and kinetic energy accumulated by the hub is comparable to that accumulated by the balance shaft, or less than 10 times greater than the potential and kinetic energy of the axis, or smaller than that of the axis. 'axis.
  • the moment of inertia of the hub is generally neglected because it is significantly lower than the moment of inertia of the balance.
  • the moment of inertia of the hub is of the order of magnitude of 0.001 mg ⁇ cm 2 , that of the axis 0.010 mg ⁇ cm 2 and that of the balance 10 mg ⁇ cm 2 .
  • the only function of the hub according to the invention is to provide a bearing surface for the launcher whip 7.
  • the hub 3 is a separate part of the plate 4.
  • the hub 3 and the plate 4 are integrated into a single element.
  • axis 2 which provides a bearing surface of the launcher whip: in this case the presence of the hub 3 is not necessary.
  • the hub 3 is devoid of rays; its mass is thus concentrated near the center, so as to reduce its moment of inertia.
  • the hub 3 is advantageously made of silicon or of another material with a lower density than that of the axis 2, in order to reduce its moment of inertia.
  • the hub is made of titanium and / or aluminum and / or an alloy containing at least one of these materials.
  • Blind openings 30 in a plane perpendicular to the axis 2 further lighten the hub 3.
  • Blind or through openings in other direction including holes through the hub parallel to the axis or according to any which direction, can also be used to lighten the hub 3. It is also possible to lighten the hub 3 by making it with a lighter core covered with a stronger coating on which the whip 72 of the launcher can give a pulse without deforming the hub 3.
  • the openings in the hub and / or in the plate have the sole function of reducing their mass and therefore their moment of inertia. They do not serve as fixing means, and do not allow to receive adjustment screws or to avoid breaks in the hub or plate and are not used either to fix the hub or the plate to the axis.
  • the regulating organ is devoid of a pendulum; its adjustment is done only with the raquetterie spiral 1, preferably by adjusting the length of the oscillating portion of the spiral by means of a screw perpendicular to the plate and to adjust the fixing point of the outer end of the spiral on platinum or on a bridge.
  • This system allows a very precise adjustment of the length of the hairspring, but other known types of adjustment are applicable to the hairspring.
  • the expression "regulating member without pendulum” indicates that the regulating member comprises a spring arranged to oscillate at high frequencies, for example at 50 Hz, or even at 500 Hz or more, and a solid balance shaft , that is to say an axis which determines, with a hub and / or plateau, the moment of inertia of the regulating member, no additional piece being added on this axis in order to increase the moment of inertia.
  • the diameter of the hub 3 is as small as possible, always in order to reduce its moment of inertia.
  • the diameter of the hub 3 is between 1.5 and 10 times the maximum diameter of the axis 2, for example between 5 and 6 times the diameter of the axis 2.
  • the The outer diameter of the hub 3 is identical to the outside diameter of the plate 4. If a bearing surface for the larger launcher 7 is required, it will be possible to use a hub 3 which is slightly larger than the plate 4, although its diameter preferably does not exceed not double the maximum diameter of the large plate 42.
  • the potential and kinetic energy accumulated by the hub 3 is less than that which is accumulated by the axis 2 at each oscillation, preferably negligible compared to that of the axis 2.
  • the hub 3 can also be an integral part of the axis 2.
  • the hub 3 and the plate 4 are integrated in a single element, for example made by bar turning, which carries the plate pin 40 is on which s' supports the launcher 7.
  • the ferrule is also integrated in this element.
  • This element may advantageously be made of titanium and / or aluminum and / or an alloy containing at least one of these materials.
  • the ferrule 5 maintains the inner end of the spring 1 on the axis 2. It is advantageously made in the form of a circular disc whose two or more segments are truncated to lighten it and reduce its momentum. inertia. A notch 50 in the side of the shell 5 is used to fix the spiral.
  • the maximum diameter of the ferrule is preferably of the same order of magnitude as the maximum diameter of the plate and the hub. For example, the diameter of the hub 3 may be between 1 and 3 times the maximum diameter of the ferrule 5.
  • the ratio ( e 3 ⁇ h ) / l, e being the thickness of the hairspring, its height and its length, is about 30 times greater than the same ratio of a conventional hairspring.
  • the spiral is advantageously constituted by a perfect Archimedean spiral, which is favorable to isochronism. Because of its stiffness and short length, it hardly deforms under the effect of gravity so that Philips end curves may not be necessary or even advantageous. Its rigidity also makes it less sensitive to disturbances due to magnetostriction. In addition, a rigid spring has the effect of increasing the frequency of oscillations and reducing their amplitude, which makes it possible to operate in a reduced oscillation range favorable to isochronism. Oscillations of reduced amplitude bring in other words a great precision to the watch. Since the oscillations of the hairspring are practically isochronous, the use of a coating, for example of silicon oxide, is no longer necessary.
  • the stiffness of the hairspring gives it an effective geometric stability: the hairspring therefore does not deform almost in different planes of space.
  • this stiff spring has a greater static and dynamic stability compared to conventional spirals at 3-5 Hz.
  • the stiffness of the hairspring also makes it non-self-starting, unlike conventional spring-balance regulators.
  • This frequency is thus inversely proportional to the square root of the moment of inertia / balance.
  • Equations 2) and 3) can not, however, be applied to the regulator of the invention, since this body is devoid of a pendulum.
  • the regulating member is therefore dimensioned by integrating in the equation 1) above a moment of inertia I calculated taking into account elements that are traditionally neglected in the prior art, notably by integrating into the calculation of the moment of inertia I the moments of inertia of the axis 2, the plate 4, the hub 3 and the spiral 1 itself, which gives us an approximation for the frequency of oscillation.
  • Prototypes were made with regulating devices capable of performing 500 oscillations per second, which makes it possible to measure timed durations with a resolution of one thousandth of a second. It is thus possible to achieve a mechanical chronograph at 500 Hz or thousandths of a second.
  • the Figures 5 and 6 illustrate an embodiment of an escapement anchor 6 that can be used with such a regulating member.
  • the regulating member of the invention is characterized by substantially higher axis rotation speeds, for example 125 times greater.
  • the impulse provided by the tooth of the anchor wheel (not shown) to the anchor 6 is therefore much shorter, the energy transmitted being on the other hand more important.
  • the rotational speed of the teeth of the anchor wheel is such that the vanes can be removed and these teeth rest directly on the anchor inlet and outlet arms by projecting the entry and exit arms. the anchor at a distance as soon as they hit them; the arms do not have time to slip on the teeth of the anchor wheel.
  • the impulse response of the anchor is faster than those known and is of the annular type.
  • the pallets are removed and an annular contact, that is to say a point contact on a stop or distributed according to a set of coplanar points and whose contact norms compete, is done directly between the teeth of the anchor wheel and the arms 62, 63 of the anchor.
  • the length of the contact between the anchor and the anchor wheel is advantageously less than one tenth of a millimeter, instead of one millimeter of the state of the art.
  • the end of these arms has a rounded shape, for example involute or spiral or involute, this shape can be adjusted finely depending on the frequency of the spiral.
  • the teeth of the anchor wheel advantageously have a shape in complementary development, which makes it possible to better adapt to high frequencies and to ensure a perfectly punctual contact.
  • These forms of anchor arms are advantageous for ensuring a fast and punctual contact between the anchor and the anchor wheel, without rebound and almost without slipping, even if, for example following an impact, the anchor or the wheel anchor are not exactly at the expected position during the impulse.
  • the anchor 6 is preferably made of a material lighter than steel, for example silicon. Through holes 64 can lighten it even more.
  • the stinger 61 is constituted by a bridge joining the two horns 60 and 65 but less thick than these horns and the rest of the anchor. The end of the stinger 61 opposite the center of the anchor is pointed to cooperate with the plateau pin 40.
  • the regulating member illustrated in the figures is advantageously used as an independent regulating member for a chronograph, in order to adjust the running of a chronograph hand in the center of the movement.
  • this regulator member may cause a hand in the center of the dial displaying thousandths of a second of a timed duration, and which travels 100 graduations on the periphery of the dial in a tenth of a second.
  • the regulating member is preferably arranged in an unusual manner very close to the center of the watch movement, which makes it possible to drive the needle directly to the center, or in any case through a gear chain as short as possible, for example a chain gear having a single wheel to reverse the direction of rotation given by the anchor wheel.
  • the axis 2 of the hairspring is in an imaginary circle coaxial with the movement and of diameter less than 50% of the maximum external diameter of the movement, preferably less than 30% of the maximum external diameter of the movement, therefore very close to the center of the movement.
