VIBRATION ISOLATOR OF LARGE CARRYING CAPACITY Russian patent published in 2014 - IPC F16F3/08 F16F1/362 

FIELD: machine building.

SUBSTANCE: invention refers to machine building industry. Vibration isolator includes a housing with a flange, two elastic sleeves from wire material of metal rubber, which are arranged in it with radial and axial preload, a cover and fastening parts. In a central hole of sleeves and the cover there arranged is a tightening screw with threaded ends, in which there are holes for cotter pins. A cylindrical wall of the housing projects on both sides of its base to the height of the sleeve in free state. Specified value of axial preload of elastic sleeves is created by tightening of a lower slotted nut, under which elastic washers are installed. Sharp edges of parts are rounded with radii. Parameters of elastic sleeves are determined so that at simultaneous action of weight force of the object and the force allowable in operation and determined by dynamic overload, which are accounted for by the vibration isolator, dynamic loading processes of the vibration isolator cannot interfere with "tails" of its field of elastic hysteresis loops.

EFFECT: achieving increase in carrying capacity and service life of a vibration isolator.
