Abstract (en)
[origin: CN114647174A] The invention relates to a tourbillon for a timepiece movement, the tourbillon comprising a holder intended to be rotatably mounted on the timepiece movement, the holder supporting a speed regulation mechanism, the speed regulation mechanism comprising a balance wheel comprising a balance wheel pivot mounted pivotably about a balance wheel axis in a balance wheel bearing, and an anchor, the balance wheel pivot being mounted pivotably about the balance wheel axis in the balance wheel bearing, and the anchor being mounted pivotably about the balance wheel axis in the balance wheel bearing. The anchor comprises an anchor pivot pivotally mounted in the anchor bearing about an anchor axis, and the anchor is arranged to cooperate on the one hand with the speed governing mechanism and on the other hand with the escapement wheel, the escapement wheel comprising an escapement pivot pivotally mounted in the escapement bearing about an escapement axis. The anchor and the escapement wheel are positioned relative to the balance wheel in such a way that the distance between the anchor axis and the balance wheel axis and the distance between the escapement axis and the balance wheel axis are greater than the outer radius of the balance wheel. The invention also relates to a movement comprising such a tourbillon and to a timepiece comprising such a movement.
