PLATE VIBRATION ISOLATOR Russian patent published in 2010 - IPC F16F7/00 

FIELD: machine building.

SUBSTANCE: vibration isolator consists of body elements and multi-layer elastic damping elements. Body elements represent two aligned split outer and inner races. The latter are coupled by at least three multi-layer elastic damping elements arranged radially. Outer race represents opposed shaped rings pinned together. Every ring has circular and at least three radial grooves. Inner race represents a threaded bolt with developed head and cover jointed together with the help of nut and flexible washer. Head body has one circular and at least three radial grooves. Head is jointed to the cover that has the groves identical to specified above. Multi-layer elastic damping element consists of a stack of plates of identical height and straight shape and two shaped bands arranged below and above aforesaid stack. Said band axial line has radius outline and ledges arranged on the ends of bands to lock elastic damping elements in inner and outer races.

EFFECT: simplified design, higher damping properties.
