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

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Stack of springs includes at least two pairs of belleville springs. Each pair contains opposite installed and free connected large bases of the 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 lesser base of next pair of belleville springs is centered. On cylindrical surface of casing groove can be made to reduce its radial rigidity. Larger bases of conical disks of each pair are with clearance in housing. Small bases of cone disks of adjacent pairs are connected with each other by damping element made in form of three-step disk. Central part of damping element is made of friction material.

EFFECT: improved efficiency in the resonant mode of vibration isolation.
