EQUIFREQUENT PACKAGE OF ELASTIC ELEMENTS BY KOCHETOV Russian patent published in 2017 - IPC F16F3/02 F16F1/32 F16F7/08 

FIELD: machine engineering.

SUBSTANCE: package of elastic elements contains a platform for installing vibration-insulated object and a base. In the center and perpendicular to the platform the rod with threaded shank and nut is fixed. The package of elastic elements consists of three vibration insulators made of plate springs with upper and lower horizontal bases. Outer vibration isolator is fastened by means of fastening elements to the platform. Each of vibration isolators is designed with different height and different angle of inclination to the rod. The vibration isolators are fixed on the rod through spacer rings. The lower horizontal bases of disc 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 bases of the disc springs. The spacer rings are made of a vibration damping material, for example, polyurethane. The horizontal lower bases of the plate springs on the side contacting the supporting plane are coated with sintered friction material based on copper.

EFFECT: increased efficiency of vibration isolation in resonance mode.
