KOCHETOV'S DRY FRICTION DAMPER Russian patent published in 2015 - IPC F16F9/30 

FIELD: machine building.

SUBSTANCE: damper contains the housing designed as a cylinder with a bottom, where the piston is located. The piston consists of parallel disks, rigidly connected to each other by a rod. The disks are installed with reference to internal surface of the housing with a clearance, and between them the frictional material is placed. A spring loads the lower disk. The cavity between the piston and bottom of the damper housing is filled with a frictional material, e.g., mesh texture elements. The upper disk loads the bottom surface of the disk-type elastic element. The power closure of elastic element with a damper is ensured by means of the spring located in the lower part of the piston. For fixing of the piston in the damper housing the lock ring fixed in the groove of the internal surface of the housing cylinder is provisioned. The lock element contacts to the upper disk and keeps the piston in an initial condition.

EFFECT: increased efficiency of vibration isolation in resonance mode.
