VIBRATION ISOLATING SUPPORT WITH VARIABLE RIGIDITY Russian patent published in 2020 - IPC F16F15/126 F16F1/38 

FIELD: machine building.

SUBSTANCE: invention relates to the field of machine building. Vibration-isolating support comprises U-shaped support frame and bearing element. Bearing element is made in the form of horizontal beam of round cross-section and installed in vertical parts of U-shaped support frame with possibility of rotation around its axis. Rotation mechanism interacts with the bearing element. Mounting plate consists of rigidly interconnected horizontal surface and flat vertical supports with holes. Vibration isolators are rigidly fixed on bearing element and installed in vertical supports of mounting plate. Vibration isolating elements are made in the form of internal and external metal bushings and a damping insert fixed between them. Shock-absorbing bushing is made of resilient material. In cross section internal cylindrical surface of external bushing and external cylindrical surface of internal bushing have N-number of sectors of different height.

EFFECT: higher vibration resistance depending on operating mode of vibration source.
