Definitions

  • the invention relates to a mechanical clockwork movement comprising at least one energy storage means arranged to drive a gear train, an output mobile of which is arranged to pivot around a motor axis, and comprising a rotary resonator which comprises at least a central mobile, arranged to pivot about a central axis, and comprising an input mobile arranged to cooperate with the output mobile.
  • the invention also relates to a watch comprising such a movement.
  • the invention relates to the field of time bases for mechanical watch movements.
  • the exhaust must be robust, withstand shocks, avoid jamming the movement (overturning), and foolproof over time.
  • the most commonly used Swiss lever escapement has a low energy efficiency, around 30%. This low efficiency comes from the fact that the movements of the exhaust are jerky, that there are falls or lost paths that are necessary to accommodate the machining dispersions, and also from the fact that several components transmit their movement. via inclined planes which rub against each other. Such mechanisms are disclosed in the documents CH293180 A and FR630831A .
  • the present invention aims to eliminate the jerks of the exhaust, in order to increase the yield.
  • a rotary resonator is proposed, characterized in particular by the possibility of maintaining rotation by a torque applied directly to the axis of the resonator, thus avoiding the dynamic losses of a conventional anchor escapement.
  • a mechanism like the Watt regulator can form a basis for a rotary resonator, but at the cost of modifications to make it isochronous and insensitive to gravity.
  • the Watt regulator is sensitive to its orientation in the gravity field, because the global center of mass of the two weights moves when the amplitude changes: the weights rise along the axis when the amplitude increases. Consequently, the contribution of gravity to the restoring force fluctuates with orientation.
  • the watt regulator is anisochronous because the return force of the weights, by spring and / or by gravity does not meet certain conditions.
  • the invention relates to a mechanical clockwork movement according to claim 1.
  • the invention also relates to a watch comprising such a movement.
  • Requirement EP16195399 by the same applicant relates to a resonator mechanism for a clockwork movement, comprising an input mobile mounted pivoting about an axis of rotation and subjected to a motor torque, and comprising a central mobile, integral in rotation with this input mobile about the axis of rotation and arranged to rotate continuously.
  • This resonator mechanism comprises a plurality of N inertial elements, each mobile according to at least one degree of freedom relative to the central mobile, and returned towards the axis of rotation by elastic return means, which are arranged to cause a return force. on the center of mass of the inertial element.
  • This resonator mechanism has a symmetry of rotation of order N.
  • This resonator mechanism comprises means of kinematic connection between all the inertial elements, and which are arranged to maintain, at all times, all the centers of mass of the inertial elements at the same distance from the axis of rotation, and the elastic return means cause an elastic potential characterized by a particular relationship. More particularly, this resonator mechanism has a pantograph type structure.
  • the aim here is to improve such a mechanism. Indeed, the drive torque and the aerodynamic resistance torque generate a radial force which adds to the elastic potential, and disturbs the isochronism.
  • the present invention proposes to orient the pivoting of the inertial elements differently, so as not to disturb the isochronism by the drive or tangential aerodynamic forces.
  • the figure 1 illustrates a variant of a resonator mechanism according to the invention, in which the pivoting of the inertial elements takes place orthogonally to the pivoting of the drive.
  • the figure 2 shows that the complex articulated link of the mechanism of the figure 1 , arising directly from the request EP16195399 , may disappear in favor of a very simple structure: the present invention has the advantage of combining the driving mobile and the resonator in a single entity which is very simple to produce.
  • This mechanism avoids the shocks and friction inherent in badly tuned groove or connecting rod-crank mechanisms.
  • the invention avoids the unnecessary multiplication of elastic elements, between the plate and the inertial element on the one hand, and between the driving mobile and the inertial element on the other hand.
