PLATE SPRING PACK Russian patent published in 2017 - IPC F16F3/10 F16F1/32 F16F1/362 

FIELD: machine engineering.

SUBSTANCE: spring pack includes a number of pairs of disc springs arranged with a gap in the cylindrical body. Each pair consists of oppositely located and movably connected to each other large bases of conical disks. The lower part of the body is rigidly connected to the base, and a cover is arranged in the upper part movably with a gap. Smaller bases of conical disk of extreme pairs are movably mounted in centering cylindrical bead of base and cover. A groove is made on the cylindrical surface of the body. The smaller bases of the conical disks of the adjacent pairs are interconnected by a damping member made in the form of a three-stage disk. Set of plate springs is made with alternate use of conical disks in each pair of plate springs with and without covering of their polyurethane. Central part of damping element is made of friction material. Screen damper is fixed on the cover which base is made in form of a plate with fastening holes. Lower washer is connected to the base of the damper. Upper pressure washer is connected to the centrally located ring enclosed by coaxially arranged ring connected with the base. Additional resilient element is positioned between the lower end of the piston and the sleeve bottom.

EFFECT: increased efficiency of vibration isolation in resonance mode.
