Definitions
- the invention relates to a watch-barrel assembly, comprising at least one barrel-drive spring mounted between, at one end, a barrel drum, and at a second end a receiving surface that comprises a barrel plug coaxial with said drum around of a pivot axis.
- the invention also relates to a watch movement comprising at least one such barrel assembly.
- the invention also relates to a timepiece comprising at least one such movement and / or at least one such barrel assembly.
- the invention relates to the field of watchmaking, and more particularly the field of energy storage barrels, for feeding a movement, a ring, or other functionality of a room watchmaking.
- one solution consists of a decrease in the diameter of the barrel shaft and the associated bung, 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.
- 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.
- a diameter even greater than that of this shoulder is necessary for a pivoting guide surface of the drum on the shaft or on the bung, combined with a shoulder limiting axial fretting of the drum.
- the respect of minimal sections of matter implies a quotation chain which results in a large size, difficult to reduce. In particular, it is not enough to reduce all the sizing, because the sections of material are then insufficient to ensure fatigue resistance.
- the document CH 319 631 in the name of FELSA SA describes a double barrel, and how is limited the frolicking of each of the drums.
- the frog of a lower drum is limited on the upper side by a flange of a sleeve, which is pushed towards a shoulder of the barrel shaft, by a nut screwed on the same shaft; and, on the lower side, by a bottom of a bung integral in pivoting of the barrel shaft by a flat.
- the length of the lower bearing of the barrel shaft, and that of a barrel of the drum determine the frolicking of the drum, in relation to these flange and bottom surfaces.
- the invention takes into account several solutions to achieve this reduction of the bung diameter.
- a first solution is to ensure the frolicking between drum and cover by the mainspring, transferring to the spring this frolicking adjustment function, in particular by equipping the spring protruding areas, such as dots, more rolled areas wide, flange reported, or the like. he it is then possible to remove the bearing shoulders of the drum and the cover on the barrel shaft or on the bung.
- a second solution is to make a bung in several parts, including two or three parts.
- This solution makes it possible in particular to make a bung of diameter smaller than the pivoting diameter of the drum.
- the plug is introduced through the bore of the drum.
- a shaft or a bung in two parts, or more, facilitates the machining of hook of hook of the shell of the mainspring.
- the bung may include, for the ratchet drive, a conventional square, or a thread. Or, in a non-limiting way, in a second variant
- the bung can still include one or more washers or diameter catch rings for its guidance in platinum and bridge.
- Another solution is to chase on the bung a setting washer of the drum-lid frog. This ring is mounted so as to avoid, for intervention on the barrel, any disassembly of a bridge.
- the different variants proposed by the invention ensure ease of machining, ease of assembly, ease of disassembly, and control of axial debates between the various components and with respect to the bridges.
