KOCHETOV CIRCULAR CONICAL SPRING Russian patent published in 2017 - IPC F16F1/32 F16F3/02 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Spring consists of alternating annular resilient cone discs of larger and smaller diameters, arranged between base and cover. Edges of discs are bent in opposite directions along radius providing connection. Each disc comprises three radial slots directed from larger to smaller base. Each of the radial slots is ended by hole for stress relieving. Internal discs and spherical segments lateral tapered surfaces are coated with vibration damping material, for example, polyurethane. Mating surfaces of inner disc lateral conical surfaces with base are coated with frictional material.

EFFECT: enabling increased efficiency of vibration isolation in resonance mode.
