FIELD: mechanical engineering. SUBSTANCE: dynamic damper has cylindrical bushing with flanges enclosing the fastening member, inertia member, and gaskets made of material with nonlinear elastic characteristic arranged between flanges. Damping bushing encloses cylindrical bushing. Inertia member is made in form of cylindrical parts installed coaxially relative to damping bushing and coupled by thread axial clearance relative to each other. Gaskets are installed with pressing between corresponding flanges and end faces of cylindrical parts. Notches and pointer can be made on outer surfaces of cylindrical parts to form readout device. Damper can be furnished with antifriction material washers placed between corresponding gaskets and end faces of cylindrical parts. EFFECT: enlarged operating capabilities. 3 cl, 3 dwg
