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

FIELD: machine building.

SUBSTANCE: invention refers to 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 resilient damping element is made in the form of a damper comprising a body in the form of a cylinder with a bottom, in which the piston is located. Piston is made as a sleeve with top and bottom collars parallel to each other and coaxial to the body. Copper-based sintered friction material is located between the collars. 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 bottom of the body is filled with friction material. Retaining ring holding the piston in its original state is fixed in the groove of the inner surface of the cylinder. Right resilient damping element is made in the form of a cylindrical helical spring, which turns are covered with polyurethane.

EFFECT: increased vibration isolation efficiency at resonance is achieved.
