KOCHETOV SPRING VIBRATION ISOLATOR Russian patent published in 2018 - IPC F16F3/10 F16F15/08 

FIELD: machine building.

SUBSTANCE: vibration isolator refers to mechanical engineering. Vibration isolator comprises a body, a base, elastic element, lower and upper limit stops of the elastic element. Body is rigidly connected to the base, executed in the form of a circular thrust bearing. 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 elastomer. In the lid, perpendicular to its axis, an opening is provided for pumping a lubricious viscous material into the system, for example solidol. 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. Ring of sintered friction material based on copper is attached to the lower part of the lower ring. Spring turns are covered with vibration damping material, for example polyurethane.

EFFECT: improved efficiency in resonant mode of vibration isolation.
