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

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Vibration isolator includes housing, base, spring, lower and upper spring stroke limiters made of elastomer and connecting the spring to the vibration-insulated object threaded bushing. Said housing is rigidly coupled with the base made in the form of round thrust block. Cylindrical shaped spring stroke lower limiter rests against the thrust block. Spring interacts with upper and lower limiters via the bottom support cup and enclosing the spring upper external cover, which is rigidly connected to the threaded bushing. On the cover a spring upper stroke limiter is attached made in form of cylindrical bushing. Screw to connect spring with object protected against vibration is fitted in said threaded sleeve. Body in an upper portion is coupled with the cover on an end surface of which there is an elastic dynamic object limiter made of an elastomer. In the cover a hole is made for the viscous lubrication material injection into the lubrication system. In lower spring stroke limiter axial hole two additional damping element are located. Inside the cylindrical helical spring a mesh element is located.

EFFECT: enabling increase in the vibration isolation efficiency.
