Annular hour-minute hand display mechanism of mechanical watch

Abstract

The invention discloses an annular hour-minute hand display mechanism of a mechanical watch. The display mechanism comprises a first center wheel component engaged with a driving wheel on barrel, a second center wheel engaged with the first center wheel component, an hour wheel, a minute wheel, a control mechanism and the like. The hour wheel and the minute wheel that are driven by idle wheel components are arranged at the center of a movement and are supported by a track mechanism or a support rack, wherein the hour wheel and the minute wheel are annular inner gears. The control mechanism limits the positions and the gap of the radial direction and the axial direction of the hour wheel and the minute wheel. The provided display mechanism has the following beneficial effects: because of the annular hour-minute hand display mechanism, a problem that the time can not be displayed normally because the center of the movement is occupied by other structures can be solved. The provided mechanism with the simple structure can be processed conveniently; demands of watch components including a middle-mounted flying tourbillion, a middle-mounted speed-regulating mechanism, a central moon-phase display unit and other units can be satisfied, wherein the watch components are arranged at the center of the movement. In addition, the control mechanism carries out limiting on the axial direction and the radial direction of the minute wheel and the hour wheel effectively, so that the frictional resistance force is reduced and thus the rotation of the minute wheel and the hour wheel becomes flexible and accurate.

Description

technical field [0001] The invention relates to a display mechanism of a mechanical watch, in particular to an annular hour and minute display mechanism of a mechanical watch without hour and minute hands. Background technique [0002] The hour and minute display mechanisms of existing mechanical watches are all set at the center of the movement, driven by the dial mechanism, and indicate the time through the pointer; however, with the diversification of watch styles, some watch components need to be installed at the center of the movement. Therefore, the existing hour and minute hand display mechanism can no longer meet the new design requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a ring-shaped hour and minute display mechanism with simple structure, good manufacturability and elegant appearance without hour and minute hands. [0004] The technical s...
