Abstract (en)
[origin: JP2018009972A] PROBLEM TO BE SOLVED: To provide a running equation of time mechanism controlled by a differential gear device.SOLUTION: The running equation of time mechanism includes a differential gear device 64, a first input of which is formed by a cannon-pinion 72 integrated with a civil minute pipe 70 on which a civil minute hand 48 is pressed, and a second input of which is formed by the equation of time cam. The differential gear device 64 includes a planetary reducer wheel set 74 via which the civil minute pipe 70 drives a civil hour pipe 84 on which is pressed the civil hour hand 46, and a planetary multiplier wheel set via which the civil hour pipe 84 drives a true solar minute pipe 102 on which is pressed a true solar minute hand 50.SELECTED DRAWING: Figure 3
