System for fixing part e.g. hairspring, on axle of time piece, has integrating device that partially adopts to shape of recess so as to integrate movement of part with movement of axle, where integrating device is attached to axle

摘要

The system (9) has an integrating device (11) with a recess (4) communicating with a hole of a part, where the part is made of crystalline silicon, crystalline silica, crystalline aluminum, silicon nitride, silicon carbide. Another integrating device (6) is attached to an axle (3), where the latter integrating device has a metallic material insert. The latter integrating device is partially adopt to a shape of the recess so as to integrate movement of the part with a movement of the axle. The metallic material insert is obtained by hot shank of metallic material under form amorphous. An independent claim is also included for a method for fixing a silicon base part on an axle.
