SPATIAL SPRING VIBRATION ISOLATOR WITH THE BUILT-IN DAMPER Russian patent published in 2018 - IPC F16F3/10 F16F1/362 F16F7/08 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Vibration isolator comprises a base, a vertical rod, an elastic element and a hinge for connecting the thrust with an elastic element or a vibration-insulated object. Hinge is an intermediate support and control element of a cross-shaped shape. Under the lower base of the vibration isolator on the interfloor overlap of the building of the textile enterprise a mesh damper is installed. Mesh damper contains a base, resilient mesh elements, upper and lower thrust washers. Base is located in the middle part of the mesh damper and is made in the form of a plate with fixing holes. Mesh resilient elements are rigidly connected to the base by means of support rings. In the upper mesh resilient element center dry friction damper is axially symmetric located. Damper is made in the form of upper press washer, rigidly connected to the centered ring, enclosed by the coaxially located ring, rigidly connected to the base. Between the lower pressure washer and lower mesh resilient element, made of three intermediate layers vibration damping material is arranged.

EFFECT: increase in the efficiency of vibration isolation in the resonance regime and an increase in the sensitivity of the vibration isolator to horizontal displacements are achieved.
