RUBBER VIBRATION ISOLATOR Russian patent published in 2018 - IPC F16F7/00 F16F3/08 

FIELD: machine building.

SUBSTANCE: invention refers to machine building. Vibration isolator comprises body in the form of bushing with opening and collar resting against the elastomeric resilient element upper end, for example rubber. Body bottom part contains rings with collar for connection with elastomer. Elastomer side surface profiles are made hyperbolic in the form of beam of equal resistance, having constant rigidity in the axial and transverse directions. Connected with the elastomer ring has on the outside surface a groove, by which the ring is locked on the support ring by screws. Cover is connected to the support ring by screws via the additional vibration dampening layer. Piston is disposed in the rubber elastic element. Piston is enclosed by the coaxially located bushing rigidly connected with the base. Between the piston lower end and the sleeve bottom the elastic mesh element is located.

EFFECT: enabling increased efficiency of vibration isolation in resonance mode.
