摘要:
A timepiece wheel governor for regulating the pivoting speed (ω) of a wheel set, about a pivot axis, including a pivoting inertia-block. It includes a spring to return this block towards this axis, and, when the wheel set pivots at a lower speed than a reference speed (ωc), this block remains confined within a first volume of revolution, and, when the wheel set pivots at a higher speed than the reference speed (ωc), this block is engaged, in one peripheral portion thereof, in a second volume contiguous with and external to the first one, this peripheral portion cooperating in this second volume with a regulator arranged to brake the wheel set and return the pivoting speed (ω) thereof to the reference speed (ωc), and to dissipate the surplus energy.

摘要:
A horological movement includes a resonator and an escapement wheel with flexible teeth, and an anchor formed of two mechanical pallets capable of abutting, when the anchor switches between its two rest positions, with any one of the flexible teeth depending on the angular position of the escapement wheel. Each flexible tooth is arranged to bend by undergoing an elastic deformation under a radial force that can be exerted by one of the two mechanical pallets abutting against this flexible tooth while the escapement wheel has an unfavourable angular position and the resonator is braked by the anchor. Each tooth has an elastic capacity to elastically absorb, in a radial direction, most of a maximum mechanical energy that the mechanical resonator may have during normal operation of the horological movement, to avoid breakage or deterioration of the escapement.
摘要:
It is intended to provide a governor that is small, does not produce wear particles or noise, is low cost, is not affected by differences in attitude, is not affected by magnetism, and has outstanding durability. The governor has a rotor that rotates using energy supplied from an energy storage means through a power transfer means, a wing having wing surfaces perpendicular to the rotational axis of the rotor, and disposed movably to an outside circumference side radially to the rotor by means of centrifugal force produced by rotor rotation, a zigzag spring disposed between the rotor and wing for pulling the wing to the inside circumference side radially to the rotor, and an opposing member disposed to the outside circumference of the rotor and having an opposing surface located opposite and separated a predetermined gap from the wing surface when the wing moves to the outside circumference side radially to the rotor.
