ROTARY BODY TORSIONAL VIBRATION DAMPER Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: invention is designed to eliminate parasitic vibrations of rotating bodies. Proposed torsional vibration damper contains housing installed on shaft for rotation and provided with working space partially filled with ferromagnetic fluid, hydraulic restrictor arranged in working space and permanent magnet installed stationarily outside the housing and enclosing the housing in zone of arrangement of ferromagnetic fluid. Housing is made in form of circular chamber enclosing the shaft and divided into compartments by inner solid radial partitions. Hydraulic restrictor is made in form of restrictors with ball valve installed in inner solid radial partitions of circular chamber with direction of passing of ferromagnetic fluid coinciding with direction of bypassing of circular chamber to one of sides.

EFFECT: improved efficiency of torsional vibration damping, enlarged operating capabilities.
