Definitions

  • the invention relates to a radial clamping system for a watch component and more, particularly, such a system for securing said component to a support member such as, for example, a pivot axis.
  • the object of the present invention is to overcome all or part of the disadvantages mentioned above by providing a clock component whose radial clamping system uses only the elastic deformation zone of the material to become integral with its support member.
  • the invention relates to a watch component comprising an opening intended to receive a support element and comprising a clamping system intended to exert a radial stress enabling said watch component to be integral with said support element characterized in that that the clamping system comprises a radial clamping device comprising a ring intended to exert said radial stress and a concentric blind recess spaced from said opening intended to allow the clearance of said ring and the clamping system further comprises a deflection device for providing more degrees of freedom to said ring relative to said support member.
  • the invention also relates to a timepiece characterized in that it comprises at least one watch component according to one of the preceding variants.
  • the invention relates to a generally annotated watch component 1 intended to cooperate with a support element 3.
  • the watch component 1 is a substantially discoidal mobile and the support element 3, a cylindrical axis with circular section, however, they can not be limited.
  • a watch component 1 mounted on a support element 3 can be seen.
  • the support element 3 comprises an axis 2 formed integrally with a pinion 4.
  • the watch component 1 comprises a hub 5 comprising an opening 7, four arm 9 and a toothed serge 11.
  • the watch component 1 is mounted on the support member 3 by means of a clamping system 13 located around the opening 7 passing through said component.
  • the clamping system 13 is intended to exert a radial stress on the axis 2 to secure the watch component 1 with the support member 3.
  • the clamping system 13 is an alternative to driving that is not always possible for materials such as crystallized silicon, silicon carbide, crystallized silica or crystallized alumina.
  • the clamping system 13 preferably comprises a radial clamping device 15 and a deflection device 17.
  • the clamping device 15 mainly comprises a ring 6 and a recess 8.
  • the ring 6 is intended to clamp the outer surface of the axis 2 It is preferably crenellated and comprises several blades 12 whose section inner 14 forms the edge of the opening 7 to better locally manage the movement of the crown 6.
  • each blade 12 is independent and moves elastically according to the own stress that is subject to it.
  • the inner section 14 is frustoconical at an angle ⁇ in order to locally increase the pinch stress.
  • the upper section of the opening 7 is thus smaller than the lower section.
  • the angle ⁇ may be between substantially 0 and 5 degrees. It is therefore understood that the clamping stress of the ring 6 of the clamping device 15 will be maximum at its free end, that is to say at the end of the blades 12.
  • the recess 8 is intended to allow a clearance of the crown 6.
  • the recess 8 is preferably blind and communicates between each blade 12 with the opening 7. Each blade 12 can thus glide independently between the recess 8 and the opening 7.
  • the deflection device 17 is intended to offer more degrees of freedom to the ring 6 relative to the axis 2. Thus, it not only allows a greater amplitude of displacement of the blades 12 but it also allows to modify more generally the direction of the inner section 14.
  • the deflection device 17 thus comprises a second recess 10.
  • the second recess 10 is blind, concentrically spaced from the first recess 8 and located on the opposite face of the watch component 1 relative to the first recess 8 as visible to the Figures 2 and 3 .
  • the depth and width of the recesses 8 and 10 are substantially equivalent.
  • the bottom of each recess 8, 10 are located in the same plane.
  • the recesses may have a depth of between 5 and 85% of the thickness of the watch component.
  • the watch component 1 is made of micro-machinable material so as to obtain a precision less than one micron.
  • Such materials may be, for example, but not exclusively silicon carbide, crystallized silicon, crystallized alumina or crystalline silica. Indeed, such materials can be etched according to the required accuracy, in particular by means of a process of the deep reactive ion etching (DRIE) type.
  • DRIE deep reactive ion etching
  • the present invention is not limited to the illustrated example but is susceptible of various variations and modifications that will occur to those skilled in the art.
  • the depths and widths of the recesses 8 and 10 may differ as their spacing relative to the opening 7 or the membership of their bottom to the same plane.
