KOCHETOV'S EQUAL-FREQUENCY ELEMENT Russian patent published in 2009 - IPC F16F1/32 

FIELD: machine building.

SUBSTANCE: proposed equal-frequency element comprises two flexible rings (1) and (2) rigidly interjointed via two symmetric flexible elements (3) and (4) with central through groove mad symmetric inside aforesaid element. One ring (2) is turned through 90 degrees with respect to ring (1). Ring axes are mutually perpendicular and lie in the plane perpendicular to the rings. The element side surfaces are inclined to the element axis. The groove side surfaces mate cylindrical surfaces formed by through holes arranged on inner and outer rings.

EFFECT: higher efficiency of vibration isolation in resonance conditions, simpler design and assembly.
