SPATIAL VIBRATION ISOLATOR OF FRAME TYPE Russian patent published in 2018 - IPC F16F3/02 F16F9/30 

FIELD: machine building.

SUBSTANCE: invention refers to the machine building. Vibration isolator comprises a frame made in the form of two supporting horizontal plates, resting against the left and right resilient damping elements. Horizontal plates are rigidly connected to the vertical plates, which in the frame lower part are connected together by the supporting plate. Platform for the vibration-insulated object is installed onto the supporting plate through a vibration damping gasket and a vertical post. Left elastic-damping element is made in the form of damper, comprising body in the form of cylinder with bottom, in which the piston is located. Piston is made in the form of cup with parallel to each other and coaxial to the body top and bottom collars. Between the collars copper-based sintered friction material is located. Conical spring rests against the lower surface of the piston, the turns of the spring are covered with polyurethane. Cavity between the piston and the body bottom is filled, for example, with sand, balls of polyurethane or the mesh structure elements. Holding the piston in its original state locking ring is fixed in the cylinder inner surface groove. Right resilient damping element is made in the form of cylindrical helical spring, which turns are covered with polyurethane.

EFFECT: enabling increase in the vibration isolation efficiency at resonance.
