  • the invention relates to the field of mechanical fabrications, and more particularly to micro-mechanics, to which it is particularly well suited.
  • the watchmaking technique uses traditional solutions to guarantee the anti-shock functions of watch components, such as a pendulum. These solutions are based on the elastic response of parts having shockproof function and on the mechanical friction between the shock and the component to be protected.
  • Traditional shockproofing is characterized in particular by a threshold acceleration below which the shockproof is not deformed and by a function of radial refocusing of the component after the impact which is relatively imprecise.
  • the invention proposes, to overcome the limitations of the prior art, a protection configuration of a component, and in particular a watch component, pivotally mounted between holding means with or without contact.

  • the first polar mass 4 and the second polar mass 6 are each magnetic material, or magnetically permeable, and are magnetic if the component 1 is not.
  • the first polar mass 4 and the second polar mass 6, preferably together define a direction D, on which is aligned a longitudinal axis of the component 1 joining the first end 2 and second end 3 of the latter, when the component 1 is inserted between the first polar mass 4 and the second polar mass 6
  • the device is calculated so that the gap distance between the first surface 5 and the second surface 7 is dimensioned so as to ensure the determined functional clearance J over the entire operating temperature range of the shockproof device 10 and the component 1.
  • FIG. figure 3 The principle of such a magnetic shockproof construction for a component 1, which is shown, in a preferred but nonlimiting application, in the form of a balance shaft, is shown in FIG. figure 3 .
  • These polar masses 4 and 6 are magnetized if the component 1 is not, they can be permeable magnetically or magnetized when the component 1 is magnetized.
  • These polar masses 4, 6 may in particular be constituted by micro-magnets, whose polarities are in agreement, and which define the pivoting of the axis of the component 1.
  • the support of this axis is guaranteed, or by two stones interposed between the axis and the polar masses or magnets, or by a curing treatment of the surface of the polar masses or magnets.
  • the two polar masses 4 and 6 are, according to the invention, each movable in a chamber limited by stops, respectively 41, 42 on the one hand, and 43, 44 on the other hand. Their movement is made according to an axial play, respectively h 1 and h 2 .
  • the minimum distance between the polar masses 4 and 6 is fixed by the stops 41 and 43 closest to the component, while the maximum distance is fixed by the stops 42, 44, the farthest from the component 1, here constituted by the bottom feats.
  • the two polar masses 4 and 6, and the component 1 are arranged in such a way that the magnetic forces and moments acting on the component are attractive forces, tending to attract the component 1 towards contact surfaces 5 and 7 that comprise either the polar masses 4 and 6, or spacers 18, 19, interposed between these polar masses and the component 1.
  • the normal position of the polar masses is that represented on the figures 1 and 3 in a position where the magnetic fields are organized around the component 1 with an imbalance, so that it comes into contact with only one of the surfaces 5 or 7, ie the surface 5 in the figures, and remains at a distance J corresponding to a predetermined functional clearance of the other of these surfaces.
  • the mobility of the polar masses 4 and 6 is preferably impeded by damping means, or else elastic return means.
  • the damping means which are preferred, can take different forms: in the case of the figure 1 , viscous friction means of the polar masses 4 and 6 in chambers in which they are movable, this viscous friction being completed by the presence of a compressible fluid between the polar masses 4, 6, and their abutments 42, 44, the farthest from component 1.
  • the damping means comprise dampers 23, 24, arranged to absorb a shock by allowing axial mobility, along the z direction of the figure 1 , or the axial pivoting direction D of the figure 3 , of one or the other polar mass 4 or 6, and to bring them slowly back to their position prior to impact. Therefore, elastic return means, such as springs, are also possible, however their stiffness must be calculated in order to avoid too stiff a return, and a reverse impact effect on the component 1, which is not desired .
  • these dampers 23 and 24 are made of neoprene, or silicone, or comprise at least a portion of neoprene, or silicone, because of the slow return characteristics in the form of these shape memory materials.
  • Such dampers placed on the internal walls of guide chambers of the polar masses 4 and 6 and inside the stops, are thus used to dissipate the kinetic energy of the shock and to prevent the polar masses or magnets from colliding with the walls or their rear stops 42, 44 during the impact, or with the stops 41, 43, the closest to the component 1, after the impact.
  • the dampers may also be constructed so as to constitute themselves the extreme stops, as in the case of the figure 3 where they are fixed at the ends of complementary guide means 15 and 17, here bores, cooperating with guide means 14 and 16 that comprise, here in the form of cylindrical surfaces, the polar masses 4 and 6.
  • dampers are however not necessary, if the axial play and the energy of the magnets are sufficiently large, and if the magnets are subjected to a viscous friction inside the encave which guarantees the dissipation of the 'energy.
  • the size and energy of the magnets used, either in the polar masses 4 and 6, or in the component 1, or in the polar masses 4 and 6 and the component 1, as well as the profile of the axis of the component 1 are optimized to produce a net magnetic attraction force towards one of the two polar masses.
  • magnets More particularly, the preferred case in which the polar masses 4 and 6 are magnetic, will also be called "magnets”.
  • the integration is done on the volume of the axis V axis .
  • the axis therefore bears on the same magnet.
  • the figure 1 thus illustrates an embodiment of magnetic balance with axial symmetry: the balance shaft 1, made of soft magnetizable or magnetic material, is between two permanent magnets 4 and 6 whose magnetic polarization is directed in the same direction corresponding to the z direction of the figure 3 , here under the reference direction D corresponding to a pivot axis of the component 1.
  • the support of the balance shaft can be guaranteed or by two stones 18, 19, interposed between the magnets and the balance shaft, or by a surface treatment of the magnets.
  • the magnets have an axial play h 1 and h 2 respectively, determined by the stops 41, 42 and 43, 44.
  • the axial clearance allows the dissipation of the energy of the shock through the movement of the magnets.
  • the radial dampers 32 and 33 have the function of preventing the axis from emerging from the region of magnetic influence, and have no contact with the component 1 during normal operation thereof. This property is valid for all positions of the watch, so also in a vertical position.
  • the axis is maintained in the region of influence of the magnetic field by the shockproofing 32 and 33: after the shock, the refocusing is guaranteed by the magnetic interaction that brings the axis exactly in the center of the magnets by aligning it perfectly in the z direction.
  • the dissipative mechanisms act on the movement of the magnets and not on the axis, the dissipation due to the friction of the pivot of the balance is almost zero during normal operation.
  • the quality factor of the regulator is thus independent of the shockproof function and can be much higher than for a traditional mechanical system.
  • the axis of the component may itself be a permanent magnet, thereby maximizing magnetic forces and torques.
  • the determined functional game J is strictly positive.
  • the functional clearance J determined is greater than or equal to 0.020 mm.
