FIELD: machine building.SUBSTANCE: this element comprises two flat resilient coaxial rings with central openings. Said rings are arranged in parallel horizontal planes and rigidly interconnected by two resilient elements. Resilient elements are arranged radially in horizontal plane and at 10-80 degrees in vertical plane. Resilient elements are made of flexible round- or square-cross-section rods or plates and concaved-convexed in spherical surface. Resilient elements are secured at rings by threaded fasteners or glue. Cavities made of rings are filled with elastically damping combine element composes by, for example, chips of solid materials filled with elastomer, for example, polyurethane. Extra elastically damping layer from, from needle-punched "Vibrosil"-type material is arranged between rings and said elastically damping combined elements incorporating sponge rubber or woven elastically damping material.EFFECT: more efficient vibration resistance in resonance mode.2 dwg |
