Embodiment Construction

[0015] Unless otherwise stated, the compositions in this specification are compositions in mass percent.

[0016] The invention relates to a timepiece component 1 , in particular a wheel set, comprising an axle-like portion 2 comprising at least one pivot 3 around a pivot axis D.

[0017] As for the material of the shaft portion, it is preferable that its Vickers hardness is between that of copper / beryllium alloy (380HV+ / −20) and that of 20AP steel or the like (740HV+ / −30).

[0018] According to the invention, at least the material forming the shaft-shaped portion 2 is a non-magnetic alloy containing at least silver and palladium and having a Vickers hardness greater than 450 HV.

[0019] In a particular embodiment, part 1 is completely non-magnetic.

[0020] In a particular embodiment, the shaft-like portion 2 runs through the entire length of the part 1 in the direction of the pivot axis D. As shown in FIG.

[0021] More specifically, the shaft-like portion 2 carries at le...

Abstract

The invention relates to a timepiece component (1) comprising a shaft-like portion (2) comprising at least one pivot (3) about a pivot axis (D), at least the material forming the shaft-like portion (2) being a non-magnetic alloy comprising at least silver and palladium and having a Vickers hardness greater than 450 HV.

Description

technical field [0001] The invention relates to a timepiece component comprising a shaft-like portion comprising at least one pivot about a pivot axis. [0002] The invention also relates to a timepiece oscillator comprising at least one such component. [0003] The invention also relates to a timepiece movement comprising at least one such oscillator and / or at least one such component. [0004] The invention also relates to a timepiece comprising at least one such movement, and / or at least one such oscillator, and / or at least one such component. [0005] The present invention relates to the field of timepiece components and wheel sets, and more particularly to the manufacture of wheel sets included in oscillators or timepiece movements. Background technique [0006] Manufacturing non-magnetic clock wheel sets is not routine practice. However, this is required in various types of movements relying on the laws of magnetism, in order notably to reduce or eliminate friction,...
