Magnetic or electrostatic pivot of a clock mobile

摘要

The subassembly has a horology runner (2) e.g. tourbillon cage, with annular peripheral surfaces (31, 32) rotating around a pivoting axis (D) of the runner. A guiding device (1) pivots about a theoretical axis (D0) of a horology mechanism. One of the peripheral surfaces is magnetized or electrified. Surfaces (11) are magnetized or electrified opposite to the peripheral surface in order to repel the peripheral surface at an interface (41) and to maintain the runner in axial levitation according to direction of the theoretical axis. An independent claim is also included for a clockwork movement.
