Definitions

  • the invention relates to a watch component intended to receive a member by driving.
  • the invention also relates to an assembly comprising such a component and a member mounted or driven into the component.
  • the invention also relates to a movement comprising such a component or such an assembly.
  • the invention finally relates to a timepiece, in particular a watch, comprising such a movement or such an assembly or such a component.
  • the assembly process for certain wheels, in particular the escape wheels, which have the particularity of being manufactured by the LiGA process in a nickel-based alloy, constitutes an area of improvement with regard to its robustness and repeatability. .
  • the prior art reports a multitude of geometries of elastic structures shaped to allow the driving of a watch component generally of a fragile nature on an axis.
  • Such structures are usually shaped with the objective of maximizing the clamping forces of the axis, while minimizing the driving forces.
  • Such structures can, for example, include elastic arms intended to be actuated in flexion when driving the axis.
  • patent applications CH700024 , WO2012079976 , EP1826634 respectively disclose a ferrule of a spiral spring and wheels each comprising an elastic structure provided with several elastic arms embedded at only one of their ends.
  • Such a structure characterized by an open or discontinuous contour, can prove to be particularly fragile and brittle. Furthermore, the expected clamping forces may turn out to be low.
  • such elastic structures may, for example, comprise a closed or continuous contour.
  • patent applications WO2016192957 And EP3056948 disclose ferrules respectively equipped with three elastic arms and four elastic arms, which project towards the inside of a first main opening for receiving the axis, so as to come into contact with the axis during the operation hunting.
  • These ferrules of trilobed or quadrilobed shape, comprise each of the second openings opening towards the first main opening. These are shaped to maximize the active length of the elastic arms, by defining embedding points of the elastic arms as far away as possible from the center of the first main opening.
  • the support points of the axis are displaced radially relative to the geometric axis of the axis under the effect of the bending of each of the elastic arms.
  • the clamping force is mainly given by the stiffness of each of the arms, which is here given by the height and thickness of the ferrule. Such geometry is therefore limiting.
  • the patent application JP2012185128 discloses, for its part, an elastic structure comprising second openings taking the form of slots, which open towards a first opening for receiving an axis.
  • the extent of these slots define, in conjunction with third openings taking the form of portions of circular crowns, the extent of elastic arms intended to come into contact with an axis.
  • the embedding zones of the elastic arms are defined by these second openings, and not exclusively by third openings.
  • this patent application proposes to implement an elastic structure close to that disclosed by the application JP2012185128 .
  • This elastic structure disclosed within an escape wheel, also comprises second openings taking the form of slots, which open towards a first opening for receiving an axle.
  • the extent of these slots define, in conjunction with third openings taking the form of portions of circular crowns, the extent of elastic arms intended to come into contact with an axis.
  • the elastic structure further comprises fourth openings taking the form of multiple oblong slots of different extents, which are arranged at the interface of the second and third openings and the teeth of the escape wheel.
  • These fourth openings are here designed to deform and thus absorb the deformations induced by the deformation of the elastic arms.
  • the aesthetics of the escape wheel are given by the geometry of the elastic structure, which here occupies most of the escape wheel board. Such an elastic structure is therefore difficult to transpose to a predefined aesthetic of a watch component. It is also difficult to transpose to any size of watch component.
  • the aim of the invention is to provide a watch component making it possible to remedy the drawbacks mentioned above and to improve the watch components known from the prior art.
  • the invention proposes a watch component making it possible to provide significant strength while avoiding deformation of the outer periphery of the component during driving.
