ABSTRACT:
An oscillation damper is mounted on an end face of a free end of a drive shaft which drives an elevator drive pulley and is driven by a drive unit gear. The oscillation damper includes a mass which is connected to the drive shaft by a spring such that when the oscillation damper is excited at the natural frequency of the damper, it oscillates in opposite phase and endeavors to compensate for the exciting force.
