VIBRATION ISOLATOR Russian patent published in 2024 - IPC F16F15/23 F16F15/27 F16F9/04 

FIELD: vibration protection.

SUBSTANCE: invention relates to vibration protection devices. Vibration isolating device comprises a telescopic guide device, made in form of oppositely directed outer and inner shells with rubber-cord shell and centering elements installed between them, and a resilient element in the form of pneumatic vibration isolators uniformly located around the outer shell, each of which includes a housing, a support and a rubber-cord shell between them. Rubber-cord shell of each of the pneumatic vibration isolators of the elastic element is made in the form of a cylinder and is connected by means of a valve electromagnetic device to a separate source of compressed air. Housing and support of vibration isolator contain flanges and fastening discs, between which ends of rubber-cord shell are fixed. Longitudinal axes of pneumatic vibration isolators of the resilient element are placed in a static equilibrium position at angle of 90° to the longitudinal axis of the guide device. Angle of arrangement of the crossing reinforcing threads of the cord of the rubber-cord shell of each of the pneumatic vibration isolators of the elastic element, made in the form of a cylinder, is 15–50° to cylinder generatrix.

EFFECT: improved operational characteristics.
