Problems solved by technology

At present, in order to increase the continuous travel time of mechanical watches, it is often necessary to provide a large barrel or several small barrels for plane linkage. Such a structure needs to occupy a large plane of the movement, thus increasing the overall size of the movement.

Abstract

The invention discloses a coaxial double-layer barrel linkage mechanism of a watch, which comprises a driving barrel part, a driven barrel part and a two-wheel part, wherein a linkage mechanism is arranged between the driving barrel part and the driven barrel part. The driving barrel component, the driven barrel part and the linkage mechanism are arranged coaxially, and the driven barrel part is engaged with the two-wheel part. The coaxial double-layer barrel linkage mechanism has the advantages that: under the condition that no wheel train is increased, two barrels are axially overlapped andlinked, which can keep the steady output of spring moment, increase the power continuance time of the barrels and prolong the continuous running time of a core; the finite axial thickness is increased, and the plane space layout is saved farthest so that the watch has the same shape size with a watch core using the same barrel.

Description

technical field [0001] The invention relates to a watch component, in particular to a coaxial double-layer barrel linkage mechanism in a watch movement. Background technique [0002] The travel time energy of a mechanical watch is provided by the mainspring. The elastic potential energy stored when the mainspring is wound up determines the length of time the watch travels. The greater the elastic potential energy, the longer the travel time of the watch. The size of the elastic potential energy depends on The length, width and thickness of the spring. When the watch is running, the mainspring gradually converts its stored elastic potential energy into mechanical energy, which provides energy for the operation of the watch. When all the elastic potential energy stored in the mainspring is released, the watch loses its energy supply and stops running. At present, in order to increase the continuous travel time of mechanical watches, it is often necessary to provide a large b...
