Definitions

  • the present invention relates to a bearing of a watch movement, in particular a shock absorber, for an axis of a rotating mobile.
  • the invention also relates to a rotating mobile of a watch movement.
  • the invention also relates to a watch movement provided with such a bearing and such a rotating wheel set.
  • the axes of revolving mobiles In watch movements, the axes of revolving mobiles generally have pivots at their ends, which turn in bearings mounted in the plate or in bridges of a watch movement.
  • the bearings For certain mobiles, in particular the balance wheel, 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 absorber bearing 1 is represented by the figure 1 .
  • a domed olive-shaped stone 2 is driven into a bearing support 3 commonly called a chaton, on which is mounted a counter-pivot stone 4.
  • the chaton 3 is held 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 bezel 3 further comprises a conical outer wall arranged in correspondence with a conical inner wall arranged at the periphery of the bottom of the bearing block 5.
  • the kitten comprises an outer wall having a surface of convex shape, that is to say domed.
  • the bearing 10 comprises a counter pivot 7 of the center plate type, comprising a cavity 8 in the shape of a cone to receive a pivot 12 of the axis 9 of the rotary wheel set, the bottom of the cavity being formed by the top 11 of the cone.
  • Pivot 12 is also tapered to fit into cavity 8, but the solid angle of pivot 12 is smaller than that of the cone of cavity 8.
  • this type of bearing has a significant drawback concerning the centering of the axis with respect to the bearing plates. Indeed, it is not possible to achieve good centering in the current configurations of this type of shock absorber. Thus, there is a high risk of having the shaft jammed by jamming between the clamps holding the shaft of the rotating mobile on either side.
  • a counter-pivot comprising a main body provided with a cavity configured to receive a pivot having the shape of a first cone having a first solid angle, the apex of the first cone being rounded with a first predefined radius of curvature included in a range from 0.2 ⁇ m to 50 ⁇ m, the cavity having a shape of a second cone having a second solid angle greater than the first solid angle, so that the pivot can rotate in the cavity, the top of the second cone being rounded and having a second predefined radius of curvature.
  • An object of the invention is, therefore, to provide a bearing, in particular a shock absorber, for an axis of a rotating mobile of a watch movement, for example an axis of a balance wheel, which avoids the aforementioned problem.
  • a bearing makes it possible to correctly center the axis in the center plate.
  • the invention relates to a bearing comprising a bearing block provided with a housing and a counter-pivot arranged in the housing, the counter-pivot comprising a main body provided with a cavity configured to receive a pivot of the axis of the rotating mobile, the pivot having the shape of a first cone having a first solid angle, the apex of the first cone being rounded with a first predefined radius of curvature comprised in an interval ranging from 5 ⁇ m to 50 ⁇ m, the cavity having a shape of a second cone having a second solid angle greater than the first solid angle, so that the pivot can rotate in the cavity, the apex of the second cone being rounded and having a second predefined radius of curvature, characterized in that the second radius of curvature is less than the first radius of curvature.
  • the bearing is remarkable in that the second radius of curvature is less than the first radius of curvature.
  • the pivot is well maintained in the cavity of the counter-pivot to prevent the axle from jamming in the bearing, while leaving it free to rotate.
  • the pivot can decenter in the bottom of the cavity and risks causing the shaft to jam, so that the balance is braked, or even completely blocked. Thanks to a radius of curvature of the bottom of the cavity smaller than that of the pivot of the axis, the pivot remains centered in the cavity, whatever the movement or the position of the timepiece.
  • this configuration of the counter-pivot makes it possible to keep a constant friction of the pivot inside the counter-pivot, whatever the position of the axis with respect to the direction of gravity, which is for example important for a balance shaft of a movement of a timepiece.
  • the cone shape of the cavity, as well as that of the pivot minimizes the difference in friction between the different positions of the axis with respect to the direction of gravity.
