CABLE VIBRATION ISOLATOR Russian patent published in 2014 - IPC F16F7/14 F16F13/00 

FIELD: machine building.

SUBSTANCE: vibration isolator includes an elastic element from pieces of a steel cable. Ends of pieces of the steel cable are fixed in upper and lower support plates by means of planks. Pieces of the steel cable are of an arc shape and located in a row on the left and on the right sides throughout the length of upper and lower support plates. Vertexes of arcs of the steel cable pieces face a vertical axis of the vibration isolator. Hydraulic dampers are fixed throughout the length of upper and lower support plates along the whole length of planks and located in a row to the left and to the right of the vertical vibration isolator axis. Each of the hydraulic dampers includes a base and guide and shock-absorbing devices. A stock is rigidly fixed at the bottom of a cylindrical sleeve with formation of a tight annular cavity. Bottom of the cylindrical sleeve is fixed in the sleeve rigidly attached to the base of a protected object. A spring is located in the annular cavity and supported with its lower end face from the bottom and with its upper end from the piston. The piston is made in the form of a disk and located with a throttling gap relative to the stock. A cover plate that is movable relative to the stock is located in upper part of the stock. Cover plate consists of an annular flange with a seal and a sleeve rigidly attached to the flange and enveloping the outer surface of a cylindrical sleeve through the seal. Spring is located coaxially to the stock and its upper end face is supported from the cover plate and its lower end face is supported from the piston. A supporting element of the vibroisolated object is fixed on the cover plate.

EFFECT: improving effectiveness and reliability of vibration isolation.
