Definitions

  • the present invention relates to a rotating mobile system of a watch movement, in particular a resonator mechanism.
  • the invention also relates to a watch movement provided with such a mobile system.
  • the axes of the rotating wheels In watch movements, the axes of the rotating wheels generally have pivots at their ends, which rotate in bearings mounted in the plate or in bridges of a watch movement.
  • the bearings For certain mobiles, in particular the balance, it is customary to equip the bearings with a shock-absorbing mechanism. Indeed, as the pivots of the axis of a balance are generally thin and the mass of the balance is relatively high, the pivots can break under the effect of a shock in the absence of a damping mechanism.
  • the configuration of a conventional shock absorbing bearing 1 is represented by the figure 1 .
  • a domed olive stone 2 is driven into a bearing support 3 commonly called chaton, on which is mounted a counter-pivot stone 4.
  • the chaton 3 is held in abutment against the bottom of a bearing block 5 by a damping spring 6 arranged to exert an axial stress on the upper part of the counter-pivot stone 4.
  • the chaton 3 further comprises a conical outer wall arranged in correspondence with a conical inner wall disposed at the periphery of the bottom of the bearing block 5.
  • the kitten has an outer wall having a convex surface, that is to say convex.
  • the friction torque on the axis due to the weight of the mobile varies as a function of the orientation of the mobile with respect to the direction of gravity.
  • These variations in the friction torque can in particular cause a variation in the amplitude of oscillation for the balance.
  • the weight of the mobile rests on the stones with holes, and the friction force generated by the weight has a lever arm relative to the axis, which is equal to the radius of the pivot.
  • the axis of the mobile is parallel to the direction of gravity, it is the end of the pivot on which the weight of the mobile rests.
  • the bearing comprises a counter-pivot 7 of the crapaudine type, comprising a cavity 8 for receiving a pivot 12 of the axis 9 of the rotating mobile.
  • a cavity may have the shape of a pyramid, the bottom of the cavity being formed by the top 11 of the pyramid.
  • the pivot 12 is tapered to fit into the cavity 8, but the solid angle of the pivot 12 is smaller than that of the cavity 8.
  • An aim of the invention is therefore to provide a mobile system of a watch movement which avoids the aforementioned problem.

  • the variation in friction between the horizontal and vertical positions with respect to gravity is reduced.
  • a contact angle less than or equal to 45 °, preferably less than or equal to 30 °, or even less than or equal arctan 1 2
  • the friction torque due to the weight in contact between the pivots and the cavities of the bearings is substantially the same regardless of the direction of gravity.
  • such an angle makes it possible to compensate for the variations in contact force due to the change in orientation with respect to gravity by lever arms of the different friction force on the two bearings.
  • this configuration of the counter-pivot makes it possible to keep a small variation in the friction torque of the pivots inside the counter-pivots, whatever the position of the axis with respect to the direction of gravity, which is by important example for a balance axis of a movement of a timepiece.
  • the pyramid shape of the cavity, as well as that of the pivot minimize the difference in friction torque between the different positions of the axis with respect to the direction of gravity.
  • the second bearing cooperates with the second pivot to allow the rotating mobile device to rotate about its axis

  • the pivots 15, 17 of the axis 16 are inserted into the housing 14, the axis 16 being maintained while being able to rotate to allow the movement of the rotating mobile.
  • the two bearings 18, 20 are shock absorbers, and further include an elastic support 21 of the counter-pivot 22 to absorb shocks and prevent the pin 16 from breaking.
  • An elastic support 21 is for example a flat spring with axial deformation on which the counter-pivot 22 is assembled.
  • the elastic support 21 is fitted into the housing 14 of the bearing block 13 and it maintains the counter-pivot 22 in the housing 14. Thus, when the timepiece is subjected to a violent impact, the elastic support 21 absorbs the shock and preserves the impact. axis 16 of the rotating mobile.
