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

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Vibration isolator comprises base, supporting platform and resilient element located between them made in form of cylindrical equifrequential spring. Object with variable process mass whose vibration shall be isolated is fixed at the supporting plate of the vibration isolator of the upper spring flange. Lower spring flange is fixed at the resilient base. Base is coupled with the lower platform of the vibration isolator by three poles with screws and elastic bushes coaxially set outside the poles. Cylindrical-conical damper made from elastomer is set under the resilient base of the lower spring flange. Damper is mounted on the lower platform of each vibration isolator by its cylindrical part. Conical part of the damper is connected to the resilient base of the spring.

EFFECT: higher efficiency of vibration isolation is achieved.
