Definitions

  • the invention relates to a shaft-ratchet assembly comprising a cocking ratchet of a watch cylinder, said ratchet comprising an axial passage for threading it onto a shaft comprising means for driving pivoting salient or reentrant.
  • the invention also relates to a watch cylinder for pivotally mounting between a plate and a bridge and comprising at least one spring housed between a pivoting drum and a cover and hung between at its outer end said drum and at its inner end a shaft which is integral in pivoting with such a ratchet about a pivot axis.
  • the invention also relates to a watch movement, comprising at least one plate and a bridge and such a cylinder.
  • the invention also relates to a watch comprising such a movement.
  • the invention relates to the field of watch mechanisms, and more particularly the energy storage mechanisms, the engine barrel type, barrel striking, or the like.
  • a solution consists of in a decrease in the diameter of the barrel shaft and the associated core, so as to increase the space available in the drum for the spring.
  • the ratio of the bead radius to the thickness of the spring is usually between 10 and 20, and the invention proposes to lower this ratio below 10, and preferably in the range between 5 and 10.
  • the dimensioning should not be done lightly, indeed a risk of breakage exists if the bung diameter is too small.
  • a ratchet is mounted axially on a barrel axis or on a bung, via a square, the ratchet being generally fixed by an axial screw.
  • the size of this screw and that of the square thus condition a minimum diameter of a pivoting surface.
  • a shoulder abutting with this pivoting surface limits axial fretting of the shaft or the bung relative to a plate or bridge carrying a stone or the like.
  • the document FR 2 329 000 A1 in the name of ETA describes a barrel with a shaft with non-cylindrical barrel, the snap hook of the spring being contained in a recess delimited by a geometric cylinder defined by the upper and lower surfaces of this barrel.
  • the document XP 001 219 052 A in the name of SOCIETE ODO describes a barrel with a non-cylindrical shaft, carrying a tube which itself carries the snap hook of the spring. This shaft has shoulders and grooves circlips.

  • the document FR 2 210 784 A1 in the name of ETA discloses a barrel with a one-piece shaft having a longitudinal groove of attachment of the spring.
  • the document DE148352C discloses a ratchet-shaft assembly with a spring for holding the ratchet on the shaft.
  • the invention proposes to improve the design of barrels designed for a large power reserve, giving them good rigidity, particularly at the ratchet, while retaining a reduced number of components, and an acceptable machining cost, or, preferably, more economical than on known barrels.
