FIELD: machine building.
SUBSTANCE: damper contains the housing designed as a cylinder with a bottom, where the piston is located. The piston is made as a sleeve with top and bottom collars parallel to each other and coaxial with the housing. The collars are installed relatively to the internal surface of the housing with a clearance. Between the collars a friction material is located. Spring, the turns of which are covered with polyurethane, rests against the bottom surface of the piston. Cavity between the piston and housing bottom is filled with vibration cushioning material crumb. In groove of the internal cavity of the cylinder the lock ring is fixed. The lock ring via the resilient ring contacts the top surface of the top collar and holds the piston in initial position.
EFFECT: increased efficiency of dampening in resonance mode.
