Background technique

In the watch movement, the driving force is the driving component, usually the driving component is composed of a barrel wheel, a barrel cover, a bar shaft and a clockwork part. When the movement is wound up, it drives the bar shaft to wind up the mainspring to store power. According to different movements, the moving parts are divided into automatic and non-automatic.

The non-automatic driving assembly consists of a barrel, a barrel cover, a barrel and a non-automatic winding part. When the movement is wound up, when the bar shaft is wound up and the non-automatic mainspring is wound, the outer hook of the mainspring in the mainspring part will catch the barrel and stop the winding.

The automatic prime mover assembly consists of a barrel, barrel cover, barrel shaft and self-winding parts. When the movement is wound up, when the barrel is wound up to tighten the automatic spring, the auxiliary spring will press the mainspring and slide on the inner wall of the barrel, and the barrel can rotate all the time so that the automatic spring is in a tight state.

The prime mover component provides torque for the movement, the parameters of the spring itself determine the magnitude of the torque, and the two parameters of the width and thickness of the spring determine the magnitude of the torque.

If the movement requires a large torque, the thickness and width of the mainspring will be increased according to the actual situation. The number of winding coils of the mainspring determines the travel time length of the movement, so when the plane space of the movement is limited, in order to ensure the torque and travel time length of the movement at the same time, the width of the mainspring can only be increased, because not all widths The mainspring of the machine can be processed, so it cannot meet the requirements of long time and high torque of the movement at the same time.
