Winding structure of mechanical watch

Abstract

The invention discloses a winding structure of a mechanical watch. The structure comprises a vertical wheel, a winding wheel part, a winding idle wheel part, a winding ratchet wheel and a clamping plate, wherein the winding wheel part and the winding idle wheel part each comprise a bearing part, or one of the winding wheel part and the winding idle wheel part comprises a bearing part, the windingwheel part, the winding idle wheel part and the winding ratchet wheel are all installed on the clamping plate, and the winding idle wheel part comprises one to four winding idle wheel bearing assemblies. The structure is advantaged in that parts of an upper chord part adopt bearing structures, so the friction force between the parts and the clamping plate is greatly reduced, the torque of the upper chord part is effectively reduced, and the structure is convenient to use, simple in machining process, convenient to adjust and high in reliability.

Description

technical field [0001] The invention relates to a winding mechanism, in particular to a winding structure of a mechanical watch. Background technique [0002] As we all know, the winding of ordinary watches is mostly completed in the form of friction transmission. With the continuous development of watch technology, in order to meet the performance requirements of watch components, if the original gear installation method is still used for transmission when winding, the torque is relatively large when winding the watch. Larger, so that when the watch is wound, it will be difficult or even impossible to twist. Ordinary watches usually adopt the form of friction transmission in the winding structure. Due to the different requirements of the watch structure, the torque of the component watch is relatively large when winding, which causes the phenomenon that the winding feels tight and cannot be twisted. [0003] The winding torque of conventional watches is generally around 70...

[0002] As we all know, the winding of ordinary watches is mostly completed in the form of friction transmission. With the continuous development of watch technology, in order to meet the performance requirements of watch components, if the original gear installation method is still used for transmission when winding, the torque is relatively large when winding the watch. Larger, so that the watch will be laborious or even unscrewable when winding the watch

Ordinary watches usually adopt the form of friction transmission in the winding structure. Due to the different requirements of the watch structure, the torque of the component watch is relatively large when winding, which causes the phenomenon that the winding feels tight and cannot be twisted.

[0003] The winding torque of conventional watches is generally around 700g·mm. Of course, the smaller the winding torque, the lighter the hand feel. However, due to the different data required by the watch parameters, the winding torque of some watches is around 1000g·mm. We learned from the experiment that the winding torque of the hand is as high as 1000g mm when friction transmission is used, which means that the wearer will feel very strenuous when winding the watch.
