The invention discloses a tourbillon structure of a
mechanical watch with counterweight compensation, and relates to the technical field of
mechanical watch application, the tourbillon structure comprises a frame plate, a first direction shaft, an outer tourbillon, a second direction shaft, an inner tourbillon, an
escapement mechanism and a
transmission system, the outer tourbillon is rotatably connected with the frame plate through the first direction shaft, and the outer tourbillon is rotatably connected with the frame plate through the second direction shaft; the outer tourbillon is rotatably connected with the inner tourbillon through a first direction shaft, the axis of the outer tourbillon is perpendicular to the first direction shaft, the inner tourbillon is rotatably connected with the outer tourbillon through a second direction shaft, the
escapement mechanism is arranged on the inner tourbillon, and the
escapement mechanism comprises an escapement wheel, an escapement fork and a hairspring
balance wheel. And in combination with an
inertia fine adjustment mechanism on the
balance wheel, collaborative optimization is performed from two levels of frame
dynamic balance and speed regulation period, so that the problem of uneven
mass distribution easily caused by a complex structure of the double-shaft tourbillon is effectively solved, and
frictional resistance and unnecessary
energy loss of the rotating frame are remarkably reduced.
