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 has a radial pinch device comprising a ring gear intended to exert said radial stress and a concentric blind recess spaced from said opening intended to allow said crown to be deflected and the clamping system further comprises a deflection device comprising a second concentric blind recess; radially spaced from said first blind recess and located on the face opposite said first recess to provide 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 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.
