FIELD: machine building.
SUBSTANCE: invention relates to machine building. Dry friction damper contains lower and upper support plates. Springs are mounted coaxial and concentric. Bottom support plate is the base. Lower disk is rigidly connected to the upper flange of the internal spring, and the upper disk is rigidly connected to the upper support plate. Lower disk is made with a deaf groove, axisymmetric to the lower disk, into which the collar enters with the end gap. End gap is made on the upper disk. Bottom cylindrical disk of the dry friction damper contains sintered friction material based on copper. Upper cylindrical disk is made of steel.
EFFECT: enabling increase in the vibration isolation efficiency in resonance mode.
