Definitions
- the invention relates to a method for determining an unbalance characteristic of a balance-balance oscillator of a watch movement. It also relates to a method for adjusting a balance-balance oscillator, comprising an implementation of such a determination method. It also relates to a pendulum or balance-balance oscillator obtained by the implementation of such a method of adjustment and a movement or a timepiece comprising such a rocker or balance-balance oscillator.
- Balance balancing is one of the important steps in the realization of a balance-balance oscillator intended to equip a watch movement. Indeed, the center of gravity of the pendulum must be in the ideal on its axis of rotation, under penalty of inducing defects that quickly become penalizing for the chronometry of the movement.
- the usual machining techniques are generally not precise enough to ensure a good balance of the balance, and this balance is further modified by the attachment to the balance of the other components that form the sprung balance (driving axis, plateau, ferrule, spiral).
- An unbalance measurement and a subsequent correction are generally undertaken on the balance provided with its single axis and the plate, before pairing with the spiral and mounting in motion.
- the static unbalance of the balance characterizes the decentering of the center of gravity of the balance relative to the axis of rotation. This unbalance is the product of the mass of the balance by the distance between its center of gravity and the axis of rotation. In the case of clockwork balances, the unbalance is typically measured in pg.cm or nN.m. With Earth's gravity, 1 g.cm corresponds to approximately 0.1 nN.m.
- the effect of unbalance varies as the sine of the azimuthal angle between the axis of the pendulum (in general, the direction normal to the plane of movement) and the vertical.
- the effect of the unbalance varies with the angle between the unbalance direction and the vertical. For example, when the axis of the balance is horizontal, there are two opposite positions where it is canceled and two positions perpendicular to the previous ones where it is maximum, but these positions are generally not the four normalized vertical positions of the watch.
- the pendulum balance is measured and adjusted before assembly with the hairspring.
- the measurement can be made by rotating the balance on its axis placed horizontally between two pivoting and measuring the oscillation and / or the reaction forces of the support by means of piezoelectric sensors.
- the unbalance value is obtained by calibration of the signal.
- a balancing operation is then carried out which consists of removing material from the balance rod in a targeted manner.
- Another possibility is to perform a "dynamic balancing", which consists in minimizing the differences between the positions by modifying the balance of the balance, based on a measurement in motion at given amplitude.
- This method is unreliable: the effect of unbalance is not necessarily preponderant compared to other sources of deviations from the amplitude for which the measurement is made.
- By playing on the balancing to correct the sum of these effects it is perfectly possible to strongly degrade the imbalance of the balance, which will disrupt chronometric performance, especially at low amplitudes. Such an approach is therefore to be avoided and is strongly discouraged in the literature.
- US3225586 provides a method of simultaneous gait adjustment and "dynamic balancing" by four screws placed on the pendulum serge, based on a measure of walking in four vertical positions.
- a "slide rule” type tool allows the result of the measurement to be converted directly into the number of revolutions to be applied to each screw.
- the correction procedure is very specific to the measuring instrument used ("Watchmaster", US21 13825) and can not be adapted to more recent measuring means.
- the patent application WO2012007460 is a recent example of a device for measuring and correcting the lack of balance of a balance.
- This application describes a method of balancing the balance-hairspring assembly, particularly when the rocker is mounted in motion.
- the balancing is done by adding and / or removing and / or moving material, in particular by means of laser machining type.

- an oscillator is equilibrated by implementing a measure of the apparent unbalance of the oscillator through a measurement of the amplitude-dependent operation, in particular of a measurement in free oscillation, that is to say carried out in a free oscillation mode of the oscillator, then implementing an unbalance adjustment, for example by adding / removing material or adjusting the position of flyweights .

- the timepiece comprises a movement 2 including an oscillator 3.
- the oscillator comprises a pendulum 4 and a hairspring 5.
- the rear face is generally the side that allows the pendulum to be accessed and to directly visualize the oscillations, and thus to allow the measurement of oscillation period and / or amplitude of oscillation by optical measuring means, more accurate than the acoustic measuring means generally used.
- the terrestrial gravitational field is represented by the vector g.
- the movement is in vertical position "12H", that is to say that the general plane of the movement is parallel to the vector g and that the index "12H" of the dial mounted on the movement is located in top relative to the vector g (NIHS notation, see also "Treatise on watchmaking", page 741).
- the other vertical positions are similarly defined: 3H (with the movement rod 6 at the top), 6H and 9H.
- Formulas show that the effect of the unbalance on the average step of four vertical positions separated by 90 °, for example the four vertical watch positions (12H, 9H, 6H, 3H), is always zero, because the effects of the unbalance in the opposite positions cancel each other two by two.
- the average step is completely independent of the unbalance and we can use only the differences between each of the four vertical positions and their average to determine the unbalance.
- the unbalance is determined, in particular, not at a single amplitude, but over a wide range of values reached by the balance-balance oscillator.
- the measurement can be performed in free oscillation, for example by removing the anchor from the movement, or by mounting the balance-balance oscillator on a setting provided for this purpose.
- the unbalance characteristic of the balance-balance oscillator is determined or calculated, in particular of the balance-balance oscillator intended to be mounted in a watch movement or arranged to be mounted in a watch movement.
- the approach to determine the unbalance is to perform a minimization by least squares from the measured curves of operates according to the amplitude in order to deduce the intensity b of the unbalance and its direction with respect to the direction 9H. To do this, we introduce the unbalance components along the x (9H) and y (12H) axes.

- the unbalance orientation is obtained by an Arctan function (by / bx), taking into account the sign.

- FIGS. 2 and 3 show, on the one hand, a measurement as a function of the amplitude in free oscillation for a mounted balance-balance oscillator and, on the other hand, the operating curves for the
- the method of determining the unbalance is based on the determination of the apparent unbalance of the balance-balance oscillator, which is the calculated unbalance to reproduce as best as possible the gait measurements as a function of the amplitude of the oscillator, in particular the Oscillator operating curves measured in the vertical position.
- Systematic measurements show that the apparent imbalance is greater than the unbalance of the balance alone (after balancing) in 80% of cases. The balancing of the balance is thus partially degraded by the assembly of the spiral on the axis of the balance, and by the assembly in motion.
- variable i of a first counter is initialized to 0.
- this first counter i is incremented by one unit.
- a third step 130 oscillation is brought into movement the balance oscillator to an i th amplitude.
- This setting can be performed as seen previously in two modes: a maintained oscillation mode or a free oscillation mode.
- the free oscillation mode the oscillator is disposed in the movement or outside the movement, for example on a setting provided for this purpose.
- the balance does not interact with an anchor or an exhaust blocker. Oscillations are unmaintained.
- This mode can be obtained by disassembling an escapement member, in particular an anchor, from the movement, or by assembling the oscillator-spiral oscillator in motion before assembling the anchor, or by mounting the balance-balance oscillator on a pose provided for this purpose.
- the oscillations are maintained by a torque transmitted by the gear train to the balance wheel through an element, like an anchor.
- the i th amplitude is preferably in the range] 200 °; 280 ° [, preferentially included in the range] 150 °; 280 ° [, more preferably still included in the range] 100 °; 300 ° [.
- the variable j of a second counter is initialized to 0.
- this second counter j is incremented by one unit.
- a sixth step 160 the motion, and therefore the oscillator, is placed in a position relative to the terrestrial gravitational field.
- this position is a vertical position, more preferably a vertical horological position, for example the 3H position, the 6H position, the 9H position or the 12H position.
- a data representative of the oscillation period of the oscillator is determined, in particular by implementing a measurement step.
- the data is the duration of an oscillation period of the oscillator or the duration of several oscillation periods of the oscillator.
- step 180 it is tested whether the variable j of the second counter is less than or equal to a threshold n. If this is the case, we go to step 150. If this is not the case, we go to a ninth step 190.
- this ninth step 190 it is tested whether the variable i of the first counter is less than or equal to a threshold m. If this is the case, we loop on step 120. If this is not the case, proceed to a tenth step 200.
- the unbalance feature can include:
- Mj amplitude or isochronism
- j 1,. .,not.
- m> 2 m representing the number of amplitudes for which measurements are made.
- the two extreme amplitudes differ by at least 30 °, preferably by at least 50 °, more preferably by at least 100 °.
- the two extreme amplitudes are on both sides of 220 °.
- the amplitudes are included in the range 200 °; 280 ° [, preferentially included in the range] 150 °; 280 ° [, more preferably still included in the range] 100 °; 300 ° [.
- the number of measurements is m> 9, more preferably m> 20.
- n> 2 where n is the number of positions of the motion for which measurements are being made.
- the at least two positions of the motion are positions in which the orientation of the oscillator differs by 90 ° or more than 90 °.
- the at least two positions of the movement comprise four positions of the movement in which the oscillation axis of the oscillator is horizontal or substantially horizontal and in which the orientations of the movement are spaced 90 ° from each other, in particular comprise the four vertical clock positions of the movement.
- the measurements in free and maintained oscillation are equivalent.
- the free oscillation measurement is more favorable because it avoids measuring the effect of the exhaust.
- the first and second counters may have no physical reality in the implementation of the method. They are there to translate the logic of the process and its implementation. It is clear that they can translate the consciousness of an operator who knows that he must make measurements for a given series of positions of the movement and for a given series of amplitudes of oscillations of the oscillator.
- the amplitudes do not need to be exactly the same for the measurements made in the different positions.
- the order of the steps can be reversed, as shown in FIG. 10b representing another embodiment of the determination method. Indeed, in such a case, it is more practical and faster to perform the measurements for different amplitudes in one position. given the movement, before positioning the movement in another position to perform measurements according to another series of amplitudes.
- the steps 131, 161, 171 and 201 are respectively identical to the steps 160, 130, 170 and 200.
- the amplitude interval considered can be extended, for example up to 400 °, which corresponds to the second amplitude value for which the effect of unbalance vanishes.
- the amplitudes are preferably in the range 200 °; 400 ° [, preferentially included in the range] 150 °; 400 ° [, more preferably still included in the range] 100 °; 400 ° [.
- the number of measurements is m> 9, more preferably m> 20.
- a first phase 210 an unbalance characteristic of a spiral balance oscillator of a watch movement is determined.
- the unbalance characteristic is determined according to the determination method according to the invention or according to the embodiments of the determination method described above.
- the unbalance of the oscillator is modified.
- the oscillator or the balance spring assembly can be modified by conventional means of material removal (milling, laser ablation, or other), addition of material (laser deposition, ink jet deposition, or other) or displacement of matter (displacement of a feeder or other).
- the unbalance can be modified to obtain a given unbalance value and orientation, in particular a zero or substantially zero unbalance value.
- Figure 4 shows an example, with a motion whose oscillator shows an apparent imbalance in motion, after assembly of the hairspring and assembly in motion, of 10.5 ⁇ g.cm according to the measurement in free oscillation. After careful milling, the apparent imbalance could be reduced to a value below 0.2 ⁇ g.cm.
- the effect on the curves of march is important and demonstrates the interest of the method for the improvement of the chronometric performances of the movement.
- FIGS. 5 and 6 show the two gait measurements as a function of the amplitude in free oscillation corresponding to the two states illustrated in FIG. 4, before implementation of the adjustment method and after implementation of the adjustment method. It can be seen that the differences in the market between positions, in particular between the vertical positions, are very much tightened by the adjustment of the apparent unbalance. This gain is also verified in sustained oscillation, that is to say in standard operation after mounting the anchor of the exhaust.
- the chronometric measurements made on this piece in the final state of unbalance and inertia adjustment show a very good behavior, with a maximum difference between the vertical positions of less than 1 s / d and, as indicated in the following table, a maximum gap between the six positions of only 3 s / d, which is excellent.
- the adjustment range is 20 ⁇ g.cm at least, which is largely sufficient to correct a residual unbalance after a first balancing performed on a single beam.
- Figure 7 illustrates the effect for a balance provided with two flyweights only arranged at 180 ° from each other. As in Figure 4, the circles around the unbalance values represent an estimate of the measurement error. By moving a weight along its tenon, unbalance is modified in a fine way in this direction.
- the adjustment range is typically ⁇ 10 ⁇ g.cm around the origin.
- Figures 8 and 9 show an example for a rocker provided with two pairs of two weights of different mass, each pair being arranged face-to-face.
- the apparent imbalance in the initial state ( Figure 8) is 8.8 ⁇ g.cm.
- the total correction to be applied has been estimated at a rotation of 0.7 revolution for the flyweight situated in the direction 3H of the movement, 0.07 turn for the 6H weight, -0.7 turn for the 9H weight and -0.07 turn for the 12H weight.
- the apparent imbalance after this correction is 0.6 ⁇ g.cm ( Figure 9), which again represents a remarkable improvement, which is clearly visible on the gait measurements as a function of the amplitude.
- the unbalance characteristic is such that the modification of the oscillator by removing this imbalance characteristic from the balance has the consequence of minimizing a criterion representative of an accumulation, for the different amplitudes, of the data differences representative of the period of time. oscillation of the balance in the different positions of the oscillator.
- the invention also relates to a rocker arm or oscillator obtained by implementing the adjustment method according to the invention.
- the invention also relates to a movement comprising such a balance-balance oscillator.
- a timepiece in particular a watch, comprising such a movement such a movement or such a rocker or such a balance-balance oscillator.
- the method of determining the unbalance characteristic includes step 160 or 161, this step includes the following substeps described in FIG. 12
- the oscillator is oscillated, the oscillator being able to freely oscillate, for example by withdrawing the anchor from the movement, or by mounting the balance-balance oscillator on a setting allowing him to swing freely.
- a second optional sub-step 320 the oscillations are stopped.
- the method of determining the unbalance characteristic includes step 170 or 171, this step includes the next sub-step described.
- a third substep 330 the data representative of the period is measured while the amplitude of the oscillation movement of the oscillator decreases.
- the method may include a step of measuring the amplitude of the oscillation motion.
- This amplitude measurement like that of the oscillation period, can be performed by an optical measuring device.
- the steps for measuring the period and / or the amplitude can be performed at regular time intervals.
- the oscillation period and / or the amplitude of oscillation associated with this period are determined.
- the measurement steps of the period can be performed at regular amplitude intervals or at given amplitudes.
- walking is understood to mean the instantaneous movement of the movement or timepiece, that is to say its movement at the instant of observation.
- diurnal walk which is the difference between two states of the timepiece separated by a 24-hour interval (in other words the difference in display of a timepiece between two separate moments exactly 24 hours) assuming that the instant walk will not change for 24 hours.
