Problems solved by technology
However, at present, this type of transmission mechanism generally has the problem of uneven force on the upper and lower barrel wheels, which leads to large power internal friction between the two barrels, large power attenuation in the later period, and easy wear of the barrel wheels, thus Decreases the accuracy of the watch

Embodiment Construction
[0015] The present invention will be further described below in combination with specific embodiments and accompanying drawings.
[0016] Such as figure 1 , 2 As shown, a series-type double barrel transmission mechanism of a watch movement includes a core wheel 1, a small steel wheel 2, a first large steel wheel 3, a second large steel wheel 4, a first barrel 5, The second barrel 6, the intermediate wheel 7 of the barrel, the center wheel 8 and the anti-reverse device 9.
[0017] The following position structure is adopted between each gear: the barrel intermediate wheel 7 and the center wheel 8 are coaxially and non-linkedly connected together, and are arranged on the central axis of the watch movement. The first barrel 5 and the second barrel 6 are arranged side by side on the left and right sides of the barrel intermediate wheel 7 and the central wheel 8 respectively. The small steel wheel 2 is arranged between the first barrel 5 and the second barrel 6, so that the conn...

A tandem type double-spring-barrel transmission mechanism of a watch movement is characterized in that a core wheel is meshed with a small steel wheel, the small steel wheel is meshed with a first large steel wheel, the first large steel wheel is connected with a spring shaft of a first spring barrel to wind a spring on the first spring barrel, and a first spring wheel is arranged on the first spring barrel; the first spring wheel, the spring box idle gear and the second large steel wheel are located on the same horizontal plane, the spring box idle gear and the center wheel are located at the position of a center shaft of the watch movement, the first spring wheel is meshed with the spring box idle gear, the spring box idle gear is meshed with the second large steel wheel, and the second large steel wheel is connected with a spring shaft of the second spring box to wind a spring on the second spring box. A second spring wheel is arranged on the second spring box and meshed with the center wheel. According to the invention, the idle wheel of the spring box is uniformly stressed in a balanced manner and is not easy to wear, the power output of the transmission mechanism is stable, and the later attenuation of power is reduced, thereby improving the time travel accuracy of the watch.
Description
technical field [0001] The invention relates to the technical field of clocks and watches, in particular to a serial double barrel transmission mechanism of a watch movement. Background technique [0002] A mechanical watch is a common watch at present, and usually includes a barrel, a winding mechanism, a non-return device, and several transmission gears, and relies on the barrel as a power to drive the pointer to rotate. At present, mechanical watches usually use a parallel double barrel transmission mechanism, which has the characteristics of sufficient power. However, at present, this type of transmission mechanism generally has the problem of uneven force on the upper and lower barrel wheels, which leads to large power internal friction between the two barrels, large power attenuation in the later period, and easy wear of the barrel wheels, thus The accuracy of the watch travel time will be reduced. Contents of the invention [0003] In order to solve the above-ment...
