VIBRATION ISOLATOR Russian patent published in 2015 - IPC F16F3/10 F16F15/08 

FIELD: machine building.

SUBSTANCE: vibration isolator comprises housing, base, elastic element, bottom and top stroke limiters of elastic element. The housing is rigidly joined with the base designed as a round axial bearing. The elastic element interacts with the top and bottom stroke limiters through the bottom bearing barrel and the top cover which is rigidly connected to the threaded bushing. The screw for connection of the elastic element with the vibration isolated object is fixed in the threaded bushing. The housing in the top part is connected to the cover on which the elastic dynamic stroke limiter of an object (the limiter is made from elastomer) is fixed. In the cover, perpendicular to its axis, a hole for pumping into the system of viscous lubricant, for example solid oil, is provisioned. The elastic element is designed as a combined dish-shaped one. The bottom part of the elastic element frame consists of the disk-shaped base disk with a ring internal cavity where the bottom elastic ring is placed. The top part of the frame is designed as a disk-shaped cover with the central ring groove. The cover by means of screws is rigidly joined with the top elastic ring. The central ring groove of the cover has a layer of vibration damping material from polyurethane on which a mounting plate for fastening of the vibration isolated object is fixed.

EFFECT: vibration insulation efficiency improvement.
