Problems solved by technology

[0008] However, isochronous motion cannot be obtained when it is desired to use flexible leaves to pivot a rotating annular balance in a manner similar to the movement of a balance with hairspring
More specifically, a perfect periodic rotational motion of the mass cannot be obtained
The reset torque is non-linear, which results in anisochronism as a function of the magnitude of the displacement of the mass and the change in the velocity of the movement

Embodiment Construction

[0040] figure 1 A first embodiment of a flexible guide 1 for a rotating resonator mechanism, in particular for a timepiece movement, is shown. The flexible guide 1 is arranged substantially in one plane. The flexible guide comprises a fixed support 2 , a movable element 26 movable relative to the fixed support 2 and two main flexible blades 3 , 4 . The main flexible blades 3 , 4 allow the movable element 20 to move relative to the fixed support 2 . By bending the main flexible blades 3, 4, the movable element 20 can be moved relative to the support 2 in a rotational movement around itself around the center of rotation. The main blades 3, 4 are preferably of equal length and uniformly angularly distributed around the movable element 20 and the central portion 6 of the flexible guide 1 to form a symmetrical pivot.

[0041] According to the invention, the flexible guide 1 comprises two translation stages 10 , 11 each attached to one end of a different main flexible blade 3 , 4...

Abstract

The invention relates to a flexible guide for a rotary resonator mechanism, in particular for a timepiece movement, comprising a fixed support, a movable element which is movable relative to the fixed support, at least two main flexible blades, by bending the main flexible blades, and a flexible guide allowing the movable element to move relative to the fixed support via a rotational movement about a center of rotation, the flexible guide being substantially arranged in a plane, the flexible guide comprising at least two translation stages, each translation stage being linked to one end of the main flexible blade, and a flexible guide such that each translating stage is configured to translate at least partially under the influence of the bending of the corresponding main flexible blade, the flexible guide comprising at least one three-stage flexible blade connecting the two translating stages.

Description

technical field [0001] The invention relates to a flexible guide with a translation stage for a rotating resonator mechanism, in particular for a timepiece movement. The invention also relates to a rotating resonator mechanism provided with such a flexible guide. Background technique [0002] Most of today's mechanical watches are equipped with a balance with spring and a Swiss pallet escapement. The balance with hairspring forms the time base of the watch. It is also called a resonator. [0003] The escapement has two main functions: [0004] - maintain the reciprocating motion of the resonator; [0005] - Count these reciprocations. [0006] Inertial elements, guides and elastic return elements are required to form a mechanical resonator. Conventionally, the hairspring acts as the elastic return element of the inertial element constituted by the balance wheel. This balance wheel is rotatably guided by a pivot rotating inside a sliding ruby ​​bearing. This leads to ...
