Watch regulator mechanism with high quality factor and minimal lubrication

摘要

PROBLEM TO BE SOLVED: To provide a clock regulator mechanism having a high quality coefficient and a minimum lubrication. A watch regulator mechanism (300) comprising a resonator mechanism (100) having a virtual pivot and a flexure bearing having a quality coefficient greater than 1,000, the resonator mechanism (100). During the operating cycle, which does not contact the escapement mechanism (200) and has at least one step of freedom, its inertial element (2) indirectly cooperates with the free escapement mechanism (200) to provide this regulator mechanism (300). Contains a pair of components (22, 32) including friction surfaces (20, 30) arranged to cooperate and contact with each other, whereby the first friction surface (20) contains silicon carbide. Formed by the surface of the containing element. [Selection diagram] Fig. 3
