VIBRATION ISOLATOR WITH PENDULUM SUSPENSION Russian patent published in 2018 - IPC F16F7/08 F16F1/362 

FIELD: machine building.

SUBSTANCE: vibration isolator comprises a spring engaged with a pendulum mechanism. Pendulum mechanism is made in the form of a threaded rod with nuts at the ends and support washers resting on the elastic elements. Upper elastic element is made of rubber and is located between the upper spring flange and the support washer. Lower elastic element is elastic-damping in the form of a mesh damper and is located between the support washer and the plate on which the vibration-proof equipment is fixed. Mesh damper contains elastic mesh elements interacting with each other, made of a mesh frame filled with polyurethane. Elastic bushing with a central bore is located in the central part of the package and is rigidly connected to a multilayer vibration damping central plate. Plate divides the damping net into two identical parts. Support rings are fixed on the central plate. Upper and lower mesh elements are connected respectively to the upper cover and the lower pressure washer of the package. In the upper mesh element there is a dry friction damper located.

EFFECT: provided is higher efficiency of vibration isolation in the resonance mode, simplified design and assembling.
