MAGNETIC PIVOT BEARING

摘要

The method of orientating a clockmaking component made of magnetically permeable or magnetic material having two ends. Two magnetic fields, each one attracting said component to a pole piece, are created on each side of said ends, with an imbalance in the strength of said magnetic fields about said component in order to create a force differential on this component and press one of said ends onto a contact surface of one of said pieces, and keep the other end away from the other pole piece. Magnetic pivot bearing comprising such a clockmaking component. It comprises a guide device with, at an air-gap distance greater than the inter-axis distance of said ends, surfaces of two pole pieces which are designed each to be attracted by a magnetic field emitted by one of said ends or each to generate a magnetic field that attracts one of said ends so that the magnetic forces applied to said two ends are of differing strengths, in order to attract one of said ends into contact with just one of said pole piece surfaces.
