KOCHETOV BELLEVILLE SPRING PACK Russian patent published in 2016 - IPC F16F3/02 F16F1/32 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Spring package includes two pairs of disc springs. Each pair contains opposite installed and free connected large bases of cone disks. Number of disk pairs depends on spring forcer and stroke. Belleville springs are located in cylindrical casing. Bottom part of casing is rigidly connected with base. Base has centering cylindrical shoulder. Lower base of cone disk of one pair freely enters shoulder. In top part of casing freely with clearance lid with centering cylindrical shoulder is installed. On shoulder the lesser base of next pair of belleville springs is centered. On cylindrical surface of casing groove can be made to reduce its radial rigidity. Conical disks enter housing with a gap. 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. Central part of damping element is made of friction material.

EFFECT: improved efficiency in resonant mode of vibration isolation.
