Turn-around moon phase mechanism of mechanical watch

Abstract

The invention discloses a turn-around moon phase mechanism of a mechanical watch. The turn-around moon phase mechanism of the mechanical watch comprises a moon phase transmission wheel series, a moon phase rapid-setting wheel series and a front valve swing plate mechanism. The moon phase transmission wheel series comprises moon phase intermediate wheel series and a moon phase wheel series. The moon phase intermediate wheel series is fixed between an upper clamping plate and a lower clamping plate. The moon phase wheel series is fixed between a moon phase rotation disc wheel and a cover sheet. The front valve swing plate mechanism is arranged below the moon phase rotation disc wheel. The turn-around moon phase mechanism of the mechanical watch has the advantages that due to the fact that a clutch wheel transmits motion to a needle setting wheel on the swing plate, the needle setting wheel is meshed with a wheel blade of a rapid-setting wheel, then, the moon phase rapid-setting wheel series is driven, the moon phase rotation disc wheel is adjusted directly, the needle setting wheel stops being meshed with the wheel blade of the rapid-setting wheel, time walking and rapid setting are achieved, a set of moon phase rapid-setting mechanism is adopted so that three functions of winding, moon phase adjusting and rapid setting are achieved , the structure is simple and reliable, part machining is convenient, and transmission efficiency is high.

Description

technical field [0001] The invention relates to a mechanical watch part, in particular to a moon phase mechanism which rotates on itself and revolves around the center of the movement. Background technique [0002] At present, the moon phase display is relatively common in mechanical watches. Usually, the moon phase mechanism sets the gears according to a certain transmission ratio, and opens a half-moon window on the dial. The moon phase disc is usually dark blue, and there are two groups of moons on it. The windows cooperate, and as the moon disk slowly moves, the first quarter moon, full moon and last quarter moon appear in sequence. [0003] In the sky, the moon rises in the east and sets in the west. On the first day of the lunar new year, the moon is almost close to the sun. At this time, the moon and the sun are almost born at the same time. Then the lunar phase deviates to the east relative to the sun. The time of landing is delayed by about 52.8 minutes per day. ...

Problems solved by technology

However, in the quick dial mechanism of the moon phase, it is difficult to process the internal gear on the same circle as the movement, and the change rate of meshing with the quick dial intermediary wheel is large, which affects the transmission efficiency
