CIRCULAR CONICAL SPRING WITH DAMPING BASIS Russian patent published in 2018 - IPC F16F3/10 F16F1/32 F16F1/362 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Spring consists of larger and smaller diameter alternating annular resilient cone discs, arranged between base and cover. Edges of discs are bent in opposite directions along radius providing connection. Each disk 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 side 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. To the spring base lower part a damping element is connected, consisting of three intermediate vibration damping layers.

EFFECT: increased efficiency of vibration isolation in resonance mode is being achieved.
