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

FIELD: machine building.

SUBSTANCE: spring consists of alternating ring resilient cone discs larger and smaller diameter, placed 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. Gauze damper base is fixed on cover. On base, made in form of a plate there is a lower washer. Mesh element is arranged on lower washer and locked by upper pressure washer. Ring connected with top washer is surrounded by ring connected to base of gauze damper. Internal discs and spherical segments side tapered surfaces are coated with vibration damping material, for example polyurethane. Conjugation surfaces of the inner annular elastic conical disk with the base are covered with a friction 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.
