摘要：
An electrically driven device includes an electric motor with a drive shaft having a first rotary axis and a drive pin eccentrically thereto, and a driven shaft having a second rotary axis and mounted for pivoting motion. The driven shaft is coupled to the drive shaft by 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 having a sliding support extending perpendicular to the first rotary axis and receiving the drive pin either directly or by a sliding block having a bearing receiving the pin. The cross slider is axially guided to move in an axial direction perpendicular to the first rotary axis and to the extension of the sliding support. The driven shaft is coupled to the cross slider by a pivotable crank arm, thereby converting a rotary motion of the drive shaft into a reciprocating motion of the driven shaft.
