Drive mechanism for driving driven wheel in direction of rotation in timepiece, has levers and eccentric for generating translational motion, where levers and eccentric are arranged such that levers drive driven wheel sequentially

摘要

The mechanism has levers (5-8) each cooperating with an eccentric (3) for generating a translation movement, so as to move relative to a driven wheel (1) upon rotation of a driving member, where the levers are arranged to cooperate with the driven wheel to provide a rotational movement in a predetermined direction of rotation (R). The levers and the eccentric for generating the translational motion are arranged such that the levers drive the driven wheel sequentially. The eccentric includes a support ring (4) connected to one of the levers.
