[origin: JP2018013480A] PROBLEM TO BE SOLVED: To provide a pivot arbor which both limits the sensitivity to magnetic fields and is improved in wear resistance, shock resistance and corrosion resistance.SOLUTION: The invention relates to a pivot arbor comprising a metal pivot at each of its ends. The metal is a non-magnetic aluminium alloy in order to limit its sensitivity to magnetic fields. At least an outer surface 5 of one of the two pivots 3 is deep-hardened to a predetermined depth with respect to the rest of the arbor to harden the pivots 3.SELECTED DRAWING: Figure 2
Abstract (fr)
L'invention se rapporte à un axe de pivotement comportant au moins un pivot (3) en métal à au moins une de ses extrémités. Le métal est un alliage d'aluminium amagnétique afin de limiter sa sensibilité aux champs magnétiques et au moins la surface externe (5) de l'au moins un des deux pivots (3) est durcie en profondeur par rapport au reste de l'axe selon une profondeur prédéterminée afin de durcir le ou les pivots (3). L'invention concerne le domaine des mouvements d'horlogerie.
