VIBRATION-INSULATED PLATFORM WITH DAMPING SPRING Russian patent published in 2018 - IPC F16F3/02 

FIELD: machine building.

SUBSTANCE: vibration-insulated platform is made in the form of consisting of the truncated cone rigid shell frame, under the upper base of which a vibration-insulated platform is located containing a body and elastic elements. Platform is installed on the base of the platform by means of a vibration-damping gasket. Horizontally placed rigid disc is attached to the bottom base of the shell. Disc rests on the base of the platform through three elastic-damping elements. Body is made in the form of rigid upper and lower plates. Three screw elastic elements secured by three pins each are placed between the plates. Annular elastic element made of elastomer and a central cylindrical elastic element with a conical buffer are attached to the bottom plate in its peripheral part. Annular buffer is fixed on the end part of the annular elastic element of elastomer. Annular buffer is also attached to the top plate. Cross section of one of the circular buffers is made of a triangular profile, and the other is rectangular.

EFFECT: enabling increase in the vibration isolation efficiency.
