摘要
A timepiece resonator mechanism having a central wheel train fixed in rotation around an axis of an input wheel train subjected to a driving torque, arranged to turn continuously, and having a plurality of N inertial elements, each movable in relation to the central wheel train, and restored to the axis by elastic restoring device. The mechanism having device between all the inertial elements that are arranged to maintain all centers of mass of these inertial elements at the same distance from the axis at any time, and the elastic restoring device cause an elastic potential such as: Vtot=(dα0/dt)2·Σj (Mj·Rj2), where: Vtot is the elastic potential, Σj is the sum over the js of the quantity between parentheses, (dα0/dt) is the speed of rotation to be imposed, Rj is the position of the center of mass G of the inertial element j of mass Mj.
