FIELD: machine building.SUBSTANCE: invention relates to machine building. Equifrequent resilient element comprises two elastic coaxially located rings. Rings are rigidly interconnected by means of six flat resilient elements with the recesses being provided between them. Four resilient elements are arranged in pairs symmetrically about horizontal axis of rings and have trapezoidal shape. Two resilient elements are radially set along the vertical axis and are of rectangular shape. Between outer and inner rings there is damping element of bushing type made in form of disc and rigidly attached to it by means of upper end of bushing. Disk is fixed by means of screws to outer surface of inner ring. Bushing enters with gap in central hole of inner ring. Vibration damping plate is attached to external ring by means of mounting screws whereon rests lower end of bushing. To inner surface of flat elastic elements attached elastic metal mesh. Inner cavity formed by rings is filled with vibration damping material, for example polyurethane.EFFECT: higher efficiency of vibration isolation in resonance mode, simplified design and assembly.1 cl, 2 dwg |
