VIBRATION ISOLATOR FOR OBJECTS WITH AN OFFSET CENTER OF MASS Russian patent published in 2018 - IPC F16F15/67 F16F3/04 F16F7/04 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering. Vibration isolator contains an elastic element, a cover and a base. System for adjusting the rigidity of the elastic element is made in the form of a flexible connection, one end of which is intended to be fixed to the object, and the other end is mounted to the lid, with the possibility of moving along and locking it. On the lid guides are made in which a creeper is placed in which the other end of the flexible connection is fixed. Elastic element is in the form of a combined spring comprising of the lower and upper support plates. Between the plates coaxially and concentric the external with right and internal with left angles of turns rise springs are installed. Bottom support plate is base on which the bottom flanges of springs are rigidly secured. Between the top support plate and top flange of the internal spring the dry friction damper is installed. Damper consists of two contacting cylindrical discs. Bottom disc is rigidly linked with top flange of the internal spring. Top disc is rigidly linked with the top support disk. On facing each other surfaces of discs the concentric diametric grooves and inserted in them shoulders are made.

EFFECT: increased efficiency of vibration isolation in resonance mode is being achieved.
