TWO-STAGE VIBRATION ISOLATOR Russian patent published in 2018 - IPC F16F3/10 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Vibration isolator is made in the form of an inverted glass consisting of a cylindrical part in which an upper part of a cylindrical helical spring, the turns of which are covered with polyurethane, is placed through the vibration damping gasket. Lower part of resilient damping element is located in sleeve fixed to the base through vibration damper. On the bottom of glass a vibration-insulated object is fixed. At least two stiffeners of triangular type are attached to the cylindrical part of the frame. Edges are supported by additional resilient elements in the form of a vibration isolator, mounted through the vibration damping liners with their lower ends on the base. Vibration isolator comprises a body and an elastic elastomer. Housing is made in the form of a square base, to which is attached a fixing element with a cylindrical sleeve by means of hollow rivets. Housing cover is made of coaxially connected by means of a circular partition of two cylindrical bushings. Resilient element is located between the base and the housing cover coaxially with the cylindrical bushings. Resilient element is located between the base and the housing cover coaxially with the cylindrical bushings.

EFFECT: enabling increase in the vibration isolation efficiency.
