MECHANICAL HOROLOGICAL MOVEMENT COMPRISING A MAGNETICALLY-PIVOTED BALANCE

A mechanism including a rotary element and a magnetic device for guiding this rotary element in rotation arranged so as to exert a radial magnetic biasing force on the rotary element when a central axis of this rotary element undergoes a radial movement relative to a given axis of rotation. The magn...

Beschreibung
Zusammenfassung:	A mechanism including a rotary element and a magnetic device for guiding this rotary element in rotation arranged so as to exert a radial magnetic biasing force on the rotary element when a central axis of this rotary element undergoes a radial movement relative to a given axis of rotation. The magnetic device includes a pair of annular magnets the first annular magnet of which is carried by the rotary element and the second annular magnet is carried by a structure of the mechanism. The second annular magnet is parallel and axially superimposed with the first annular magnet when the central axis of the rotary element is coincident with the axis of rotation, the first and second annular magnets being arranged in magnetic attraction so as to impart on one another an axial magnetic force and a radial magnetic force.
