FIELD: mechanical engineering. SUBSTANCE: damper has case, vibrator made of two bushings having [- shaped cross-section and provided with trapezium hollows in their shelves, stator having H-shaped cross-section whose shelves are provided with trapezium projections one opposite to another which are answered to the hollows of the vibrator and flexibly hysteresis member made of two multilayer blocks each of each is assembled with two belts provided with outer projections, two groups of corrugated belts interposed between them and central group of smooth belts pressed out in assembling condition and fit with interference in ring spaces which are formed with projections of stator and vibrator and cannot slide over contact surfaces of the stator. The hollows of top self of the stator are dummy so that the shelf has continuous outer cylindric surface. There is a working gap between top shelf of the stator and case that is filled with oil. Sealing rings are set on each bushing of the vibrator for axial movements. Rubber sealing spacers are fit in ring grooves of the sealing rings with interference over faces of the bushings of the vibrator. Additional rubber sealing spacers are fit into ring grooves provided with the bushings of the vibrator with interference over faces of outer ring of the bearing.. EFFECT: improved design. 2 cl, 10 dwg
