摘要:
The gear (48) according to the invention for an electric toothbrush serves for the transmission and reforming of a rotational movement provided by an electric motor (58) into a particularly careful and effective cleaning movement of a cleaning element (40). The ratio of the distance between the longitudinal mid-axis of an output shaft (30) and the longitudinal mid-axis of a drive shaft (60) of the gear (48) and of the distance between the longitudinal mid-axis of a shaft (60, 78) driving a cam (72) of the gear (48) and the longitudinal mid-axis of the cam (72) amounts to at least 10:1.
