FIELD: machine building.
SUBSTANCE: invention relates to vibration protection means. Damper is made in the form of a cylindrical shell made of a vibration damping material, to the ends of which flat supports consisting of three layers are joined. Internal cavity of the cylindrical shell is filled with a set of two damping disks fixed free-fit with a clearance on the elastic axis located coaxially with the cylindrical shell. Between the damping disks cylindrical helical spring is arranged. Internal cavities between damping disks and flat stops are filled with elements of a mesh structure. Cavity between damping disks in which the cylindrical helical spring is located is filled with polyurethane.
EFFECT: increased efficiency of vibration isolation in resonance mode is being achieved.
