KOCHETOV EQUIFREQUENTIAL PACKAGE OF CUSHION ELEMENTS Russian patent published in 2016 - IPC F16F3/02 F16F1/18 

FIELD: machine building.

SUBSTANCE: package of elastic elements consists of three vibration isolators, made from cushion springs with upper and lower horizontal shelves. Outer vibration isolator is fastened by means of fastening elements to the platform. Each of vibration isolators consists of three cushion springs of different height and different angle of inclination to a package rod. Vibration isolators are fixed on rod pack through spacer rings and are arranged relative to each other at angle of 120°. Lower horizontal shelves of springs of each consequent vibration isolator are located with increase by the height, determined by a conic surface inscribed in points of bending of lower horizontal shelves of the cushion springs. Spacer rings are made from vibration damping material, for example polyurethane. Lower horizontal shelves on side in contact with base are coated with copper-based sintered friction material.

EFFECT: higher efficiency of vibration isolation.
