REGULATOR DEVICE FOR THE OPERATION OF A MECHANICAL TIMEPIECE MOVEMENT |
摘要 |
The regulator device (2) for the operation of a mechanical timepiece movement comprises: - a chassis (4); - a resonator fixed to said chassis and comprising a first annular magnetic structure (8) having a first number N1 of magnets, arranged regularly in a circle, and an elastic structure (20,21,22); - a second annular magnetic structure (14) having a second number N2 of magnets and defining a central axis (16) around which said structure turns, N2 being different from N1. The resonator is arranged such that a resonance mode in which the first magnetic structure undergoes a curvilinear movement, preferably substantially circular, around the central axis can be excited by the rotation of the second magnetic structure. The two magnetic structures define a cycloidal magnetic gearing such that the regulator device incorporates a frequency reducer between the resonance frequency and the frequency of rotation of the second magnetic structure rigidly attached to an escapement wheel. |
