VIBRATOR ISOLATOR FOR PROCESS EQUIPMENT Russian patent published in 2015 - IPC F16F3/10 F16F15/08 

FIELD: machine building.

SUBSTANCE: vibrator isolator consists of a casing and a resilient element interacting with a unit. The casing is made as a base plate where two guiding sleeves with bottoms turned to the base plate are fixed by a layer of cast polyurethane. Resilient elements are set inside the guiding sleeves symmetrically to their axes; the elements are made as two rings placed in vertical planes that are mutually perpendicular to each other. The lower bearing surfaces of springs rest in round disks from antifriction material and the upper ones - in the cap covering the cast polyurethane layer with a gap. By means of a fastening element the cover is connected to a load bearing threaded element, for example, a bolt with its head being covered by the cast polyurethane layer. The sleeves on the side of the open part are fitted by ring flanged edges, coaxial sleeves' axes on which resilient rings are fixed with a gap in respect to the inner cap surface and serve as resilient limiters of moving elements of the vibration absorber. Under disks of the guiding sleeves the resilient damping elements are installed, they are made in form of cone springs filled with polyurethane.

EFFECT: increased efficiency of vibration isolation in resonance mode.
