FIELD: machine building.
SUBSTANCE: resilient damping support comprises bearing fitted on rotor, damper, o-rings, cover for sealing of damper and holes for supply of oil in bearing and damper. Damper is located in bearing housing. Alternating projections are made along axis of perforated profiled ring on outer and inner surfaces at distance between projections along arc to diameter of rings within 0.26…0.32. Perforation holes are made between ledges. External projections are offset relative to inner by half distance between them. Ring is installed in gap of damper. Hole is located in cover diametrically opposite relative to oil feed hole.
EFFECT: achieved are elimination of oil flow in circumferential direction, improved damping and reduction of vibration level.
