Abstract (en)
[origin: WO2015121014A1] Method for servicing and regulating the frequency of an horology resonator mechanism (1) about its natural frequency (ω0), characterized in that use is made of at least one regulator device (2) acting on said resonator mechanism (1) with a periodic movement. Said periodic movement imposes a periodic modulation of the resonant frequency and/or of the Q factor/or of the position of the quiescent point of said resonator mechanism (1), with a regulating frequency (ωR) that is comprised between 0.9 and 1.1 times the value of an integer multiple of said natural frequency (ω0), said integer being greater than or equal to 2 and less than or equal to 10. Said periodic movement imposes a periodic modulation of the Q factor of said resonator mechanism (1) by acting on the losses and/or the damping and/or the friction of said resonator mechanism (1).

Procédé d'entretien et de régulation d'un mécanisme résonateur (1) d'horlogerie autour de sa fréquence propre (É0), caractérisé en ce qu'on met en oeuvre au moins un dispositif régulateur (2) agissant sur ledit mécanisme résonateur (1) avec un mouvement périodique. Ledit mouvement périodique impose une modulation périodique de la fréquence de résonance et/ou du facteur de qualité et/ou du point de repos dudit mécanisme résonateur (1), avec une fréquence de régulation (ÉR) qui est comprise entre 0.9 fois et 1.1 fois la valeur d'un multiple entier de ladite fréquence propre (É0), ledit entier étant supérieur ou égal à 2.
