US 2024/0369970 A1 · METHOD FOR MANUFACTURING A TIMEPIECE ASSEMBLY, AND TIMEPIECE ASSEMBLY

Abstract

The timepiece assembly includes a first timepiece component (10) assembled with a distinct second timepiece component (20), the first timepiece component (10) having at least one functional part and a receiving opening (11) which can constitute a connecting hole distinct from the functional part, the wall delimiting the receiving opening (11) forming a first connecting surface (12), the second timepiece component (20) having a second connecting surface (22) and being assembled securely with the first timepiece component by direct or indirect contact between the respective first and second connecting surfaces (12, 22) at a securing surface, wherein at least one of the first and second connecting surfaces (12, 22) or a third connecting surface of an optional intermediate third component (30) is made of silicon oxidized by heat treatment so that the first and second timepiece components are secured to one another by the growth of an oxidized silicon layer

Dependent claims

A timepiece assembly comprising:

a first timepiece component,
a second timepiece component distinct from the first timepiece component, the first timepiece component being assembled with the distinct second timepiece component,
the first timepiece component comprising a receiving opening or connecting hole, the wall delimiting the receiving opening or the connecting hole forming a first connecting surface,
the second timepiece component comprising a second connecting surface and being assembled securely with the first timepiece component by direct or indirect contact between the respective first and second connecting surfaces of the first and second timepiece components at a securing surface,
wherein at least one of the first and second connecting surfaces or a third connecting surface of an optional intermediate third component is made of silicon oxidized by heat treatment so that the first and second timepiece components are secured to one another by the growth of a layer of oxidized silicon.

2 more elements

A method for manufacturing a timepiece assembly comprising a first timepiece component and a distinct second timepiece component, wherein the method comprises:

assembling the first and second timepiece components in a minimal-clearance intermediate configuration so that the second timepiece component is positioned in a receiving opening or connecting hole of the first timepiece component, a first connecting surface of the first timepiece component being positioned facing a second connecting surface of the second timepiece component, optionally via an interior and exterior third connecting surface of an intermediate third component of the which has a shape of a sleeve, at least one of the first and second connecting surfaces or the optional interior and exterior third connecting surface being made of silicon;
heat treating the timepiece assembly in the intermediate configuration so as to obtain growth of a layer of oxidized silicon on the at least one connecting surface made of silicon until a predefined level of securing-together of the first and second timepiece components (is obtained.
