Definitions
- the present invention relates to a coupled resonator for a regulating system, that is to say an assembly formed of two resonators whose coupling makes it possible to stabilize a frequency and thus to make it more independent of external stresses.
- the invention will be more particularly illustrated by the regulating system of a clockwork mechanical movement for which isochronism is a quality factor.
- Patent GB 1,138,818 published in 1967 describes a coupling device in which the alternations of a first oscillator excite by shock a tuning fork, that is to say without direct mechanical connection.
- the newer regulating devices essentially rely on devices associating a mechanical regulator, such as a sprung balance, associated by an electromagnetic coupling with an electronic regulator, said coupling being essentially carried out by means of magnets arranged in the arms or in the balance serge.
- a mechanical regulator such as a sprung balance
- an electromagnetic coupling with an electronic regulator
- the present invention therefore aims to overcome the disadvantages of the aforementioned prior art by providing a coupled resonator of simpler and more reliable design.
- the invention relates to a coupled resonator comprising a first low-frequency resonator for example of the order of a few hertz and a second resonator at higher frequency, for example of the order of 100 Hz.
- the invention is characterized in that the first resonator and the second resonator comprise permanent mechanical coupling means, said coupling making it possible to stabilize the frequency in the event of external disturbances, for example in case of shocks.
- the two resonators can be manufactured separately from identical or different materials, and then mechanically assembled by any means known to those skilled in the art, such as bonding, riveting, welding or interlocking.
- Both resonators can also be made in one piece in a single material.
- the materials used must have a certain elastic constant and may, for example, be chosen from metals or alloys, or amorphous, monocrystalline or polycrystalline materials, such as glass, quartz and silicon or its derivatives.
- the invention will be more particularly illustrated by a coupled resonator formed by a hairspring and a tuning fork, such a resonator being able to be integrated into the regulating system of a timepiece, in particular a wristwatch capable of receiving shocks.
- FIG. 2 is a partial representation of a second embodiment
- FIG. 3 is a partial representation of a third embodiment
- FIG. 4 corresponds to a graph representing the eigenfrequencies of the coupled system
- FIG. 5 corresponds to a graph showing the influence of the coupling on the stabilization of the frequency.
- the hairspring 1 basically comprises a first resonator consisting of a hairspring 1 typically having a frequency of the order of a few hertz and a second resonator consisting of a tuning fork 2 typically having a frequency of the order of one kilohertz.
- the curve inside 3 of the hairspring 1 is fixed in a conventional manner on a ferrule 5 for securing to a balance shaft and the tuning fork 2 also includes two arms 4, 6 connected by a foot 8.
- foot 8 of the tuning fork 2 is fixed in known manner to a fixed part of the watch movement, such as the rooster.
- the hairspring 1 and the tuning fork 2 are mechanically connected permanently.
- the arm 6 of the tuning fork 2 is extended by the curve on the outside 7 of the hairspring 1.
- the two resonators are made in one piece, by known techniques that depend on the materials used. These materials are obviously materials having a certain elastic constant "k", such as metals and alloys, or amorphous materials, monocrystalline or polycrystalline, such as glass, quartz, silicon or its derivatives.
- This basic embodiment will further illustrate an example of how such coupling has a favorable effect on the stabilization of the frequency.
- the first resonator namely the hairspring 1
- the second resonator namely the tuning fork 2
- the arm 6 of the tuning fork 2 comprises a notch 10 in which the end of the curve outside the spiral 7 is engaged, possibly completing the mechanical connection by gluing.
- the foot 8 of the tuning fork 2 further comprises a constriction 12 for fixing to a fixed part of the watch movement, and which can influence the coupling constant "k c " between the two resonators.
- FIG. 3 represents other variants allowing a great freedom to adjust the coupling constant "k c " between the first and the second resonator and the natural frequency of the second resonator.
- the foot 8 may comprise material recesses which will make it possible to modify the coupling constant "k c ". They could also be performed on any other part of the tuning fork 2, especially on the free arm 4 to modify the mass "m” and therefore the natural frequency of the tuning fork. Conversely, according to an embodiment not shown, it would be possible to add mass at any point in the second resonator.
- FIG. 3 also shows another variant, which can be combined with the preceding variant, to modify the natural frequency of the first resonator.
- the free arm 4 comprises in fact a counterweight 16, movable on said arm 4 and can be immobilized at a determined location, for example by means of a clamping screw 18.
- the tuning fork 2 when the tuning fork 2 is made of quartz along crystallographic axes for obtaining a piezoelectric effect, electrodes may be provided on the arms 4, 6 to generate electrical energy. In the case of a wristwatch this energy may for example be used to illuminate the dial.
