Arrangement for mechanical interface of an MEMS micromotor with a clock wheel and time piece incorporating this arrangement

摘要

The arrangement has a pinion (62) coaxial to and arranged above a rotor (42), and connected in rotation to the rotor by a pin (66) received in openings i.e. slots (68), where the rotor is driven by an actuator of a micro electro-mechanical system micromotor. The pinion is meshed with a toothed wheel (28), and the pin is integrated to the pinion. The pinion is supported on a bearing (60) when an axial effort oriented downwards is applied on the pinion. The rotor is guided in rotation by a shaft (64) mounted in the plate.
