Definitions

  • the invention relates to a clockwork regulating mechanism, comprising, arranged on a plate, a resonator mechanism of a quality factor Q, and an escapement mechanism which is subjected to a couple of driving means which comprises a movement, said resonator mechanism comprising an inertial element arranged to oscillate relative to said plate, said inertial element being subjected to the action of elastic return means fixed directly or indirectly to said plate, and said inertial element being arranged to cooperate with a mobile of exhaust that includes said exhaust mechanism.
  • the invention also relates to a timepiece movement comprising motor means, and such a regulating mechanism, the escapement mechanism of which is subjected to the torque of these motor means.
  • the invention also relates to a watch, more particularly a mechanical watch, comprising such a movement, and / or such a regulating mechanism.
  • the invention relates to the field of clockwork regulation mechanisms, in particular for watches.
  • the balance-spring constitutes the time base of the watch. It is called here resonator.
  • This escapement must be robust, not disturb the pendulum far from its point of equilibrium, resist shock, avoid jamming the movement (for example during a reversal), and therefore constitutes a nerve component of the watch movement.
  • a balance spring oscillates with an amplitude of 300 °, and the lifting angle is 50 °.
  • the lifting angle is the angle of the pendulum on which the fork of the anchor interacts with the pin, also called ellipse, of the pendulum.
  • the lift angle is distributed on either side of the balance point of the pendulum (+/- 25 °), and the anchor tips +/- 7 °.
  • the Swiss anchor escapement belongs to the category of free escapements because, beyond the half-lift angle, the resonator no longer touches the anchor. This characteristic is essential for obtaining good chronometric properties.
  • a mechanical resonator comprises an inertial element, a guide and an elastic return element.
  • the balance constitutes the inertial element
  • the hairspring constitutes the elastic return element.
  • the pendulum is guided in rotation by pivots, which rotate in smooth ruby bearings.
  • the associated friction is at the origin of energy losses and walking disturbances.
  • the losses are characterized by the quality factor Q of the resonator.
  • a range of operation compatible with a resonator with flexible rotary guide, in particular with blades, is typically from 6 ° to 15 °. This results in a certain lift angle value, which must be twice the minimum operating amplitude.
  • the document EP3032352A1 in the name of LVMH describes a clock regulator comprising two inertial regulating members, each mounted on a support by an elastic suspension in order to be able to oscillate in translation.
  • the two members are linked by a lever so as to form a rotary resonator with virtual pivot.
  • the regulator has a dowel pin and an anchor.
  • the document EP2990885A1 in the name of ETA SA describes a mechanical watch movement comprising a resonator, an escapement associated with this resonator and a time information display, this display being driven by a mechanical motor device via a gear train whose operation is clocked by the exhaust , at least the resonator being housed in an enclosure in which a reduced pressure prevails relative to atmospheric pressure.
  • the exhaust is a magnetic exhaust comprising an escape wheel coupled directly or indirectly to the resonator via a non-contact magnetic coupling system, this magnetic coupling system being formed so that a non-magnetic wall of the enclosure passes through the magnetic exhaust so that a first part of this exhaust is located inside the enclosure, while a second part of this exhaust is located outside this enclosure.
  • the document EP2894520A2 in the name of NIVAROX SA describes an oscillating mechanism for a clock movement, comprising a first rigid element (200) and a second rigid element, each designed to be fixed to an element different from said movement, one of which is capable of move relative to each other and pivots around an axis.
  • the oscillating mechanism is a flexible monobloc mechanism with variable geometry, and comprises a first elastic return means ensuring an elastic connection between the first rigid element and an intermediate rigid element, and comprises at least a second elastic return means providing an elastic connection between this intermediate rigid element and this second rigid element.
  • the first rigid element, the first elastic return means, the intermediate rigid element, the second elastic return means and the second rigid element are coplanar on a plane and designed to deform on this plane.
  • the resonator must have an acceptable size, compatible with its housing in a watch movement, it is not possible to date to realize a flexible rotary guide of very large diameter, or several pairs of blade levels, which would theoretically allow, by the series of successive flexible guides, to obtain an oscillation amplitude of the inertial element of several tens of degrees: it is therefore advisable to use a flexible guide with one or two levels of blades at most, for example as known from the document EP3035126 on behalf of THE SWATCH GROUP RESEARCH & DEVELOPMENT Ltd.
  • the effect of choosing a flexible rotary guide is that the amplitude of the balance is reduced, and that it is no longer possible to use a traditional Swiss lever escapement, which requires an amplitude of the balance clearly greater than half lifting angle, that is to say greater than 25 °.
  • a regulator comprising a resonator with flexible guidance therefore requires a specific exhaust mechanism, with a dimensioning different from what a conventional Swiss anchor escapement would be designed to operate with the same inertial element of the resonator.
  • the present invention has the overall objective of increasing the power reserve and accuracy of current mechanical watches. To achieve this objective, the invention combines a resonator with flexible rotary guide with an anchor escapement optimized to maintain acceptable dynamic losses and limit the chronometric effect of the release.
  • the invention relates to a regulating mechanism according to claim 1.
  • Such resonators with flexible rotary guidance have very high quality factors, for example of the order of 3000, to be compared with a quality factor of 200 for a conventional watch.
  • the dynamic losses kinetic energy of the escapement mobile and of the anchor at the end of the pulse
  • These losses can therefore become too large, with a high quality factor, in relative level with respect to the energy transmitted to the balance.
  • a plate pin secured to the inertial element must penetrate a certain value, called penetration, into the opening of the anchor fork.
  • this platform pin must then be able, after releasing the pin, to be kept at a certain distance, called safety, from the horn of the fork opposite to that on which it was in contact immediately before release.
  • the invention also sets out to impose a particular relationship, according to claim 4, between the dimensions of the anchor fork, the penetration and safety values, and the values of the angles of lifting of the anchor and of the inertial element, to ensure that the dowel retracts correctly from the fork, once the lifting half-angle has been traversed.
  • the invention also relates to a timepiece movement comprising motor means, and such a regulating mechanism, the escapement mechanism of which is subjected to the torque of these motor means.
  • the invention also relates to a watch, more particularly a mechanical watch, comprising such a movement, and / or such a regulating mechanism.
  • the invention combines a resonator with flexible rotary guide, in order to increase the power reserve and the precision, with an anchor escapement optimized to maintain acceptable dynamic losses and limit the chronometric effect of the release.

  • the resonator lifting angle ⁇ , during which the plateau pin 6 is in contact with the anchor fork 8, is less than 10 °.
  • dynamic multi-body simulations make it possible to evaluate the efficiency and the delay of this escape mechanism as a function of the inertia ratio between the inertia of the inertial element and the inertia of the anchor, what usual kinematic simulations do not allow establishing.
  • the analytical model of the system has thus shown that, if we want to limit the dynamic losses, a particular condition links the inertia of the anchor, the inertia of the inertial element, the quality factor of the resonator, and the angles of lifting of the anchor and the inertial element: for a coefficient ⁇ of dynamic losses, the inertia I B of the inertial element 2 with respect to the main axis DP on the one hand, and the inertia I A of the anchor 7 relative to the secondary axis DS on the other hand, are such that the ratio I B / I A is greater than 2Q. ⁇ 2 /( ⁇ . ⁇ . ⁇ 2 ), where ⁇ is the angle of lifting of the anchor which corresponds to the maximum angular stroke of the anchor fork 8.
  • the inertia I B of the inertial element 2 with respect to the main axis DP on the one hand, and the inertia I A of l anchor 7 relative to the secondary axis DS on the other hand are such that the ratio I B / I A is greater than 2Q. ⁇ 2 /(0.1. ⁇ . ⁇ 2 ), where ⁇ is the angle of lifting of the anchor which corresponds to the maximum angular travel of the anchor fork 8.
  • the resonator lift angle ⁇ which is an overall angle, taken on either side of the rest position, is less than twice the amplitude angle from which deviates the maximum inertial element 2 with respect to a rest position, in one direction of its movement.
  • the amplitude angle, from which the inertial element 2 deviates as far as possible relative to a rest position is between 5 ° and 40 °.
  • the plate pin 6 penetrates into the anchor fork 8 with a penetration stroke P greater than 100 micrometers, and in a release phase the plate pin 6 remains at distance from the anchor fork 8 with a safety distance S greater than 25 micrometers.
  • the plate pin 6 and the anchor fork 8 are dimensioned so that the width L of the anchor fork 8 is greater than (P + S) / sin ( ⁇ / 2 + ⁇ / 2), the stroke of penetration P and the safety distance S being measured radially with respect to the main axis DP.
  • the useful width L1 of the plate pin 6, visible on the figure 6 is slightly less than the width L of the anchor fork 8, and more particularly less than or equal to 98% of L.

  • the invention defines, by construction, a new dowel-fork layout, which has a very particular characteristic, according to which the horns of the fork are more apart, and the dowel is wider, than for a Swiss anchor mechanism of known type with a usual lifting angle of 50 °.

  • the flexible guide comprises two flexible blades 5 crossed in projection on a plane perpendicular to the main axis DP, at the virtual pivot defining the main axis DP, and located in two parallel and distinct levels. More particularly still, the two flexible blades 5, projected onto a plane perpendicular to the main axis DP, form an angle between them between 59.5 ° and 69.5 °, and intersect between 10.75% and 14.75% of their length, so as to give the resonator mechanism 100 a deliberate isochronism defect opposed to the defect in delay in the exhaust of the exhaust mechanism 200 .
  • the resonator thus presents an anisochronism curve which compensates for the delay caused by the exhaust.
  • the free resonator is designed with an isochronism defect opposite to the defect caused by the anchor escapement. We therefore compensate for the delay in exhaust by the design of the resonator.
