FIELD: machine building.
SUBSTANCE: invention relates to mechanisms and machines protection systems against vibrations. Rod cylindrical damping element is made in the form of coaxially arranged cylindrical shells, between which tubular damping elements are located. Connecting the cylindrical shells end faces flat rigid stops are made of three layers. Lower and upper layers are made rigid, and between them a damping layer is located. Cylindrical shell inner cavity is filled with a set of fixed to the elastic axis two damping disks. Between the damping disks cylindrical helical spring is arranged. Between damping disks and flat rigid stops the internal cavity is filled with crumb of vibration damping materials filled with polyurethane, or of the solid damping material.
EFFECT: higher efficiency of damping in the resonance mode is provided.
