摘要： The device for pivoting an arbor of a rotating member, on a determined pivot axis, inside a timepiece movement includes at least one magnetic bearing including a magnet which exerts a force of attraction on a pivot made of magnetic material, of the arbor, and an endstone arranged between the magnet and the pivot, the endstone being formed of a material having a hardness greater than 500 HV and a friction coefficient less than or substantially equal to 0.1 with the material of which the pivot is made. The material forming the endstone has a high magnetic permeability and the endstone has, in cross-section to the pivot axis, smaller dimensions than those of the magnet, said endstone being arranged in the timepiece movement to be centred on the determined pivot axis.

摘要： A method for orienting a timepiece component including ferromagnetic material, where, on both ends of this component, two magnetic fields each attract it onto a pole piece, with an unbalance in the intensity of these fields around this component, in order to create a differential in the forces thereon and to press one of these ends onto a contact surface of one of the pole pieces, and to hold the other end at a distance from the other pole piece. A magnetic pivot includes such a component with two ends. It includes a guide device with surfaces of two pole pieces each generating a magnetic field attracting one of these ends, the magnetic forces exerted on the two ends being of different intensity, in order to attract only one end into contact with only one of these pole piece surfaces.

摘要： The device for pivoting an arbor about a determined axis includes at least one magnetic bearing including a magnet which exerts a force of attraction on a pivot, made of magnetic material, of the arbor. Further, the bearing includes a magnetic flux centring structure arranged between the magnet and the pivot, and a support for the centring structure. This centring structure includes a peripheral portion and a central portion resiliently connected to the peripheral portion by at least one connecting element, the central portion being formed of a highly magnetically permeable material and having smaller dimensions than those of the magnet. The peripheral portion is rigidly force fitted to the support so that the central portion is centred on the pivot axis.
