Definitions

  • the present invention relates to the field of devices regulating the relative angular speed between a magnetic structure and a resonator magnetically coupled so as to define together an oscillator.
  • the regulating device of the present invention sets the pace of a mechanical watch movement. More particularly, the invention relates to magnetic escapements for mechanical watch movements in which there is provided a direct magnetic coupling between a resonator and a magnetic structure. In general, their function is to subject the frequencies of rotation of the mobiles of a counter gear train of such a watch movement to the resonant frequency of the resonator.
  • the regulating device therefore comprises a resonator, an oscillating part of which is provided with at least one magnetic coupling element, and a magnetic escapement arranged so as to control the relative angular speed between a magnetic structure forming this magnetic escapement and this resonator. It replaces the balance-spring and the classic escapement mechanism, in particular the escapement with a Swiss type anchor and a toothed escape wheel.
  • the resonator or the magnetic structure is integral in rotation with a mobile driven in rotation with a certain motor torque which maintains an oscillation of the resonator.
  • the mobile is incorporated in a train or more generally a kinematic chain of a mechanism. This oscillation makes it possible to adjust the relative angular speed between the magnetic structure and the resonator thanks to the magnetic coupling between them.
  • the devices for regulating the speed of a wheel, also called a rotor, by a magnetic coupling, also called a magnetic coupling, between a resonator and a magnetic wheel have been known for many years in the watchmaking field.
  • a magnetic coupling also called a magnetic coupling
  • Several patents relating to this field have been granted to Horstmann Clifford Magnetics for inventions of CF Clifford.
  • the regulation device described in this document has various drawbacks, in particular an anisochronism problem (a non-isochronism, that is to say an absence of isochronism), namely a significant variation of the pulsation (angular speed ) of the rotor as a function of the engine torque applied to this rotor.
  • Such an anisochronism results from an anisochronism of the oscillator formed by the resonator and the magnetic wheel.
  • the reasons for this anisochronism have been understood in the context of the developments which have led to the present invention. These reasons will emerge later on reading the description of the invention.

  • Each of the two pluralities of magnets has the same number of magnets distributed angularly in a regular manner and defining the same angular period ⁇ P , the first track being phase shifted by half a period (corresponding to a phase shift of 180 °).
  • the resonator 6 is symbolically represented by a spring 15, corresponding to its elastic deformation capacity defined by an elastic constant, and by an inertia 16 (symbol 'I') defined by its mass and its structure.
  • This resonator comprises a magnet 18 having a rectangular shape and defining a coupling element to the magnetic structure.
  • This magnet has an axial magnetization in the opposite direction to that of magnets 10 and 12, so that it is arranged in repulsion of the latter.
  • the magnet 18 is located above the mobile 8 so that its center of mass is axially superimposed on an intermediate geometric circle defining a common limit or interface of the two concentric and contiguous annular tracks when the resonator is in its rest position.
  • the magnets 10 and 12 form zones of magnetic interaction with the magnet 18 of the resonator and they are located alternately on one side and the other of the above-mentioned intermediate geometric circle, they define a sinuous magnetic path (sinusoidal ) with a determined angular period ⁇ P , which corresponds to the angular period of each of the first and second annular tracks 11 and 13.
  • ⁇ P angular period of each of the first and second annular tracks 11 and 13
  • the magnet 18 oscillates along this path magnetic winding and the angular speed ⁇ of the wheel is defined substantially by the oscillation frequency of the resonator. There is therefore a synchronization between the frequency of the resonator and the frequency of rotation or pulsation of the mobile 8.
  • the geometric shape of the magnet 18 whose active end part (shown in the Figure 1 ) defines, in axial projection in the general geometric plane of the magnetic structure, a rectangular surface.
  • this active end part has a general and average external contour or profile, in a plane parallel to that of the magnetic structure, which is substantially rectangular.
  • the length of said rectangular surface is radial while its width, less than the length, is angular relative to the central axis of the annular or tangential magnetic structure relative to the above-mentioned intermediate geometric circle. In the example described here, this length is approximately twice the width.

  • the magnetic potential energy is defined relative to a reference energy which corresponds to the minimum potential energy of the oscillator.
  • this potential energy corresponds to the work necessary to bring the magnet from a position of minimum energy to a given position.
  • this work is provided by the motor torque applied to the mobile 8.
  • the potential energy accumulated in the oscillator is transferred to the resonator when the coupling member of the resonator returns to an energy position lower potential, in particular minimum potential energy, by a radial movement relative to the axis of rotation of the mobile (that is to say according to the degree of freedom of the useful resonance mode).
  • this potential energy is transformed into kinetic energy and elastic energy in the resonator by the work of the magnetic force between the coupling element of the resonator and the magnetic structure. This is how the motor torque supplied to the wheel is used maintain the oscillation of the resonator which in turn brakes the wheel by adjusting its angular speed.
  • the outer annular track 11 defines an alternation of low potential energy zones 24 and high potential energy zones 26 while the inner annular track 13 defines, with an angular offset of an angular half-period ⁇ P / 2 relatively at the first track (that is to say a phase shift of 180 °), an alternation of low potential energy zones 28 and high potential energy zones 30.
  • the layout 32 gives the position of the center of the magnet 18 when the oscillator 2 is energized and the mobile 8 is therefore driven in rotation with a certain motor torque.
  • This line is a representation of the oscillation of the magnet of the resonator 6 in a frame of reference linked to the mobile.
  • the areas of low potential energy correspond to the areas between the magnets of the magnetic structure while the areas of high potential energy correspond to the areas of these magnets, ie in situations where the magnet 18 is at least partially superimposed on the magnets of the magnetic structure.
  • the magnets are arranged in attraction, alternatively in the case where the magnetic structure or the coupling member of the resonator is made of ferromagnetic material, there is a spatial inversion between the zones of low potential energy and the high potential energy zones relative to the case of repellant magnets.
  • the oscillator accumulates magnetic potential energy at each alternation of the oscillation essentially when the magnet 18 has reached its maximum amplitude. and it begins to return to its zero position.
  • the potential energy of the oscillator decreases over a large part of each half-wave.
  • the force F exerted on the magnet of the resonator is given by the gradient of the potential magnetic energy, which is perpendicular to the level curves 22.
  • the angular component degrees of freedom of the magnetic structure
  • the radial component degrees of freedom of the resonator
  • the angular force corresponds on average to a braking force of the mobile because the angular reaction force mainly opposes the direction of rotation of this mobile over a period of oscillation.
  • the radial force corresponds to a pushing force on the oscillating structure of the resonator.
  • the force F (see Figure 2 ) has a radial component over a significant distance between the extremes of oscillation 32. A thrust force therefore acts on the magnet of the resonator in most of each half-wave.
  • the inventors have thus found that a pushing force on a relatively extended path outside of a zone located around the zero position disturbs the oscillator; which varies its frequency as a function of the torque supplied, and thus of the amplitude of oscillation, and is therefore a source of anisochronism.
