KOCHETOV SPRING VIBRATION ISOLATOR Russian patent published in 2016 - IPC F16F3/10 F16F15/08 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Vibration isolator includes housing, base, resilient element, resilient element top and bottom stroke limiters. Said housing is rigidly coupled with the base composed by round center pad. Resilient element interacts with top and bottom stroke limiters via bottom support barrel and top cover, which is rigidly connected with threaded bushing. In threaded bushing screw for connection of resilient element with vibration isolated object is fixed. Housing in an upper portion is coupled with the cover whereon there is an elastic dynamic object limiter made of an elastomer. Cover comprises an axially perpendicular hole for injection of a ductile lubricant, e.g. solid oil, into the system. Resilient element comprises two coaxially arranged rings and cylindrical helical spring. Rings are interconnected by three resilient flat plates. Spring is located between cover lower surface and upper ring. To lower ring bottom part ring from friction material is attached. Spring turns are covered with vibration damping material, for example polyurethane.

EFFECT: improved efficiency in resonant mode of vibration isolation.
