摘要
The gear driven display is for an electromechanical calendar and provides both day and month display. The changeover at the end of a month is provided by a differential gear unit. The main gear has 48 teeth and directly associated with it is a similar sized gear with only 4 teeth (72). The drive pinion (85) has a profiled associated pinion for meshing with the main gear. When the gear with 4 teeth goes through one revolution, the display moves through 1/12 of a revolution.
