Definitions
- the invention 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 hooked between, at its outer end said drum and at its inner end a shaft, which is integral pivotally with a ratchet about a pivot axis, said barrel having a monobloc subassembly coaxial with said shaft and grouping, around a core, said shaft and said ratchet which is located in the immediate vicinity of said platen
- 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 joined to this pivoting surface limits axial fretting of the shaft or the bung relative to a plate or a bridge carrying a stone or the like.
- 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 a machining cost acceptable, or, preferably, more economical than the known barrels.
- the invention thus relates to a watch cylinder for pivotally mounting between a plate and a bridge, according to claim 1.
- 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 monobloc subassembly 10 has an upper shoulder 15 whose travel is limited by a lower surface 65 of the drum 6.
- the ratchet 2 is between, on the one hand, a spring-receiving surface 31 of the shaft 3, at which the spring 7 is fixed on the shaft 3, and, on the other hand, a lower shoulder 22 which the one-piece subassembly 10 at the core 4, This lower shoulder 22 limits the race of the monobloc subassembly 10, resting on an upper surface 93 of the plate 9 or a stone 92 that includes the plate 9.
- the drum 6 has an upper surface 61 whose travel is limited by a lower surface 53 of the bridge 5 or a stone 52 that includes the bridge 5.
- the drum 6 pivots, at a bore 62 that it comprises, on an upper bearing 13 of the shaft 3 of the monobloc subassembly 10.
- the ratchet 2 is disposed between, on the one hand, a lower end surface 63 of the drum 6 which is situated on the opposite side to this upper surface 61 with respect to the spring 7 enclosed in said drum 6, and on the other hand this shoulder. lower 22 that includes the monobloc subassembly 10 at the core 4.
- the plate 9, or the stone 92 that it comprises, comprises a bore 91 in which pivots a lower bearing surface 41 of the monobloc subassembly 10.
- the one-piece subassembly 10 is pivoted at an upper bearing surface 13 in a bore 62 that the drum 6 has at an end gun whose external bearing surface 64 pivots in a bore 51 of the bridge 5 or a stone 52 that includes the bridge 5.
- the one-piece subassembly 10 comprises, at the level of the shaft 3, a spring receiving surface 31 for receiving the spring 7 which is greater in diameter than the upper end surface 13 which extends it, on the opposite side to the ratchet 2. And this shaft 3 comprises, between this reception surface 31 and the upper surface 13, a shoulder 15 arranged to cooperate abutting abutment with the inner surface 65 of the drum 6.
- This internal surface 65 is in the vicinity, on the opposite side of the same flange 66 of the drum 6, of an upper surface 61 of the drum 6, whose stroke is limited by a lower surface 53 of the bridge 5 or a stone 52 that includes bridge 5.
- the shaft 3 comprises a spring-receiving surface 31 which is preferably of smaller diameter than that of the core 4 at a lower bearing surface 41 of the one-piece subassembly 10, and carries the spring 7, or at the level of this spring receiving surface 31, on which the spring 7 is immobilized by friction or welded, or on a hook 32 that comprises the shaft 3 around the spring receiving surface 31.
- the core 4 comprises, in the vicinity of the ratchet 2, a lower bearing surface 41 pivoting in a bore 91 of the plate 9 or a stone 92 that includes the plate 9.
- the frolicking of the drum 6 is limited in lower bearing relative to the bridge 5, by an upper surface 61 of the drum 6 which is limited by a lower surface 53 of the bridge 5 or a stone 52 that includes the bridge 5.
- the frolicking of the drum 6 is limited in upper support relative to the ratchet 2, by a lower end surface 63 of the drum 6 which is located on the opposite side to the upper surface 61 with respect to the spring 7 enclosed in the drum 6.
- This lower end surface 63 is bounded by an upper surface 21 of the ratchet 2 of the monobloc subassembly 10.

- the first example of the figure 1 is advantageous because the monobloc subassembly 10 combines the functions of cover, ratchet, shaft, and core, without machining complexity other than the hook 32 for hooking the spring 7. There are three times of frolic.
- the upper surface 21 of the ratchet 2 intended to cooperate with the lower surface 63 of the drum 6 may advantageously be subjected to a teflon coating, "rilsan®", or the like, to reduce the friction torque between the drum 6 and the ratchet 2.
- the advantage of this construction is that there is no limit to the diameter of the core.

- This spring 7 preferably has a width / thickness ratio of between 3 and 23, and more particularly between 9 and 21.
- the maximum radius of the spring receiving surface 31 of the shaft 3 (without taking into account the possible extra thickness specific to a hook 32), made of steel or stainless steel, for example stainless steel hardenable 4C27A (also called according to the various standards 1.4197, ASTM 420F, or DIN X22 CrMoNiS 13 1), relative to the pivot axis D is less than nine times the maximum thickness of the spring 7.
- the embodiments illustrated make it possible to obtain a ratio between the maximum radius of the spring receiving surface 31 of the shaft 3 and the thickness of the spring 7 between 3 and 9, and preferably between 4 and 6, preferably close to five.
- the invention also relates to a watch movement 100 comprising at least one plate 9 and a bridge 5 and such a cylinder 1.
