DRIVE MECHANISM FOR A VIBRATION-TYPE DRY-SHAVER COMPRISING A SHEAR FOIL AND A RECIPROCABLE CUTTER, DRIVEN BY A SINGLE-PHASE SYNCHRONOUS MOTOR

摘要

: Drive mechanism for a Vibration-type dry-shaver comprising a shear foil and a reciprocable cutter, driven by a single-phase synchronous motor. A drive mechanism for a dry-shaver comprises a shear foil and a cutter (29) which is reciprocable relative to said foil by means of a single-phase synchronous motor (3). The motion of the shaft (5) of the motor (3) is transmitted to the cutter (29) by means of a cam (7) mounted on the shaft (5), the cam (7) being constantly in contact with the roller (13). At least the surface of the transmission roller (13) and/or the cam (7) is made of an elastic material, for example rubber.
