摘要:
An electrically driven device includes a housing, an electric motor with a drive shaft having a first rotary axis and a drive pin connected to the drive shaft eccentrically with respect to the rotary axis, and a driven shaft having a second rotary axis and mounted in the housing for performing a pivoting about the second rotary axis. The driven shaft is coupled to the drive shaft by a gear mechanism having a scotch yoke mechanism converting a rotary motion of the drive shaft into a reciprocating pivoting motion of the driven shaft. The scotch yoke mechanism includes a cross slider receiving the drive pin and having a sliding support extending perpendicular to the first rotary axis. The cross slider is guided in the housing by at least two elastically deformable elements. The driven shaft is coupled to the cross slider by a pivotable crank arm, converting a rotary motion of the drive shaft into a reciprocating of the driven shaft.
