SEWING MACHINE COMPRISING A DAMPING DEVICE

摘要

The invention relates to a sewing machine which comprises a stationary sleeve (41) enclosing an oscillating shaft (38) in order to dampen the torsional oscillations of the latter. Between the shaft (38) and the sleeve (41) a gap (43) is configured. Said gap (43) is filled with a viscous substance (24) and is closed by sealing elements (44). When the shaft (38) is moved relative the sleeve (41) a viscous friction occurs in the viscous substance and brings about a damping effect.
