Definitions

  • the invention relates to a device for pivoting a clockwork movement shaft comprising a pierced stone fixed in a kitten traversed by a pivot of said axis of revolution, and a counter pivot stone indirectly fixed on a plate of said movement by at least said kitten, said counter-pivoting stone having a first bearing surface arranged to cooperate in abutment with the distal end of said pivot, and arranged so that, in abutment position of said pivot on said counter-pivot stone; the normal tangent common to said pivot and said first bearing surface is oblique to said axis at a tilt angle, said normal and said axis together defining a counter-pivot plane having a first angular orientation at an angle yaw with respect to a reference direction of said platen.
  • the invention also relates to a watch movement comprising such a device.
  • the invention also relates to a watch comprising such a watch movement or / and such a device.
  • the invention relates to the field of pivotal guidance of watch-making trees for watches, and more particularly of balance shafts.
  • One of the causes of these gait variations is the difference in the behavior of the pendulum pivot, in contact with the counter-pivot stone between the two horizontal positions. This difference in behavior is caused, for example, by the different forces of the hairspring, closer to the pivot in one of the horizontal positions relative to the other, coupled with the play of the pivot in the orifice of the stone.
  • the counter pivots have the essential functions, on the one hand the reduction of the friction at the pivot, and on the other hand the good distribution of the oils.
  • the document CH 239 786 in the name of DITISHEIM describes a pendulum shaft pivoting device or the like, having a counter-pivot stone with an oblique surface at the point of contact with the end of the shaft.
  • the document CH 702 314 B1 In the name of PATEK PHILIPPE describes a bearing pad, made of a crystalline material, and a receiving hole of a pivot comprises faces which are planar, and located in crystalline planes of this crystalline material.
  • the document CH 704 770 A2 in the name of ULYSSE NARDIN describes a pivot whose free end has a contact end radially offset relative to the pivot axis, in the direction of the periphery of the pivot.
  • the document EP 2 400 355 A1 in the name of SWATCH GROUP R & D describes a shock absorbing bearing comprising a support with a housing receiving a pivot system in which is inserted a shaft tigeron; the bearing comprises elastic means of amorphous material exerting an axial force on the pivot.
  • the invention proposes to carry out a shaft pivoting guide remedying the drawbacks of the prior art, by reducing the differences in the behavior of the shaft between the different positions of the watch.
  • the invention relates to a device for pivoting a clockwork movement shaft comprising a pierced stone fixed in a kitten traversed by a pivot of said axis of revolution, and a counter-pivot stone fixed indirectly on a platinum of said movement by at least said kitten, said counter-pivot stone having a first bearing surface arranged to cooperate in abutment with the distal end of said pivot, and arranged so that, in abutment position of said pivot on said counter pivot stone, the normal to the tangent plane common to said pivot and to said first bearing surface is oblique with respect to said axis at a tilt angle, said normal and said axis together defining a counter-pivot plane having a first angular orientation at a yaw angle with respect to a reference direction of said platen, characterized in that said first bearing surface is flat, and said device comprises means for adjusting said yaw angle or / and said tilt angle for adjusting and adjusting the movement of said movement.
  • the invention also relates to a watch movement comprising such a device.
  • the invention also relates to a watch comprising such a watch movement or / and such a device.
  • the invention proposes to describe various means for influencing the behavior of the pivot, and, through this intermediary, the running of the watch. These means make it possible to influence or regulate this behavior in order to equalize the steps, especially in the two horizontal positions.

  • This arrangement avoids the disadvantage of the prior art flotation of the pivot sliding on a horizontal counter-pivot stone within the limits permitted by the play of the pivot in the hole of the pierced stone.

  • the mobility of the cabochon 9 relative to the plate 6 is preferably restricted to a simple pivoting as visible on the figures 13 and 14 , without play or preferably with friction, or with a differential translational movement, with respect to the plate 6, of three points of its periphery, with a reduced clearance allowing only this warpage of the stone against the pivot 4 by compared to plate 6, as visible on the figure 16 .
  • the adjustment means 20 comprise angular indexing means 22 for maintaining the adjustments made on the watch.
