TORSIONAL OSCILLATION DAMPER Russian patent published in 2019 - IPC F16F15/173 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Torsional oscillation damper consists of case, cover, flywheel arranged inside housing in fluid medium with high viscosity, and flange with holes for attachment of damper. Flywheel is composite and located on the base with slots uniformly located on its outer surface relative to each other. In the parts of the flywheel on the side of their inner diameters there are protrusions entering the base grooves and arranged evenly relative to each other. Between the flywheel parts there are at least one intermediate disc with projections on its outer diameter. Ledges enter slots in housing on outer diameter from inner side. Also between parts of flywheel there is at least one internal spacer ring located on base between ends of flywheel parts. Intermediate discs are fixed by outer spacer rings on outer diameter of housing on inner side. Parts of flywheel and inner spacer ring are fixed on base by locking ring. Base is located on sliding bearings.

EFFECT: higher efficiency of torsional vibrations damping due to viscous friction surface increase without weight and dimensions increase.
