STACK OF PLATE SPRINGS Russian patent published in 2018 - IPC F16F3/02 F16F1/32 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering. Stack of springs includes several pairs of plate springs arranged with clearance in cylindrical housing. Each pair contains opposite installed and free connected large bases of cone disks. Lower part of the housing is rigidly connected to the base, and a cover is movable in the upper part with a clearance. Smaller bases of the extreme pairs conical disc move into the centering cylindrical collar of the base and the cover. On the cylindrical surface of the casing the groove is made. Small bases of cone disks of adjacent pairs are connected with each other by damping element made in form of three-step disk. Set of belleville springs is made with alternating use of cone disks in each pair of disk springs with their polyurethane and without it. Damping element is made of hard vibrating damping materials. Three vibration damping plates are fixed on the cylindrical surface of the housing, connected with each other around the cylindrical surface of the housing by strapping with a cable.

EFFECT: increased efficiency of vibration isolation in resonance mode is being achieved.
