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 document CH 282 774 discloses a needle whose head is formed by a cylindrical body of metal whose thickness is greater than the rest of the needle forming a barrel.
  • 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 according to claim 1.
  • 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 silicon carbide, crystallized silicon, crystallized silica or crystallized alumina.
  • the clamping system 13 preferably comprises a radial clamping device 15 and a locking 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 8 and the opening 7.
  • the recess 8 is also intended to cooperate with the locking device 17.
  • the recess 8 may have a depth of between 5 and 85% of the thickness of the watch component.
  • the locking device 17 is intended to maintain a minimum stress of the clamping system 13 against the axis 2 by limiting the sway of the blades 12 when the overall positioning is considered satisfactory.
  • the locking device 17 comprises a substantially discoidal locking key 10 comprising a hole 16 and on the lower face a collar 18.
  • the hole 16 is through and of larger internal section than the outer diameter of the axis 2 in order to slide without fat friction.
  • the collar 18 of general annular shape has a substantially frustoconical inner section 19 in order to progressively lock the positioning of the blades 12.
  • the locking key 10 is slid against the axis 2 through its hole 16 so that its flange 18 is received in the recess 8.
  • the flange 18, once inserted, thus prevents the displacement of the blades 12 towards the recess 8 by abutment of its inner section 19 by locking their positioning.
  • 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.
  • the locking key 10 is formed of a ductile material such as, for example, a metal.
  • the present invention which is defined by the appended claims, 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 dimensions of the recess 8 and the flange 18 may differ as their spacing relative to the opening 7.
