IMPROVED VIBRATION ISOLATOR WITH LARGE LIFTING CAPACITY (VBGU) AND METHOD OF ITS ASSEMBLAGE Russian patent published in 2015 - IPC F16F3/08 F16F1/362 

FIELD: machine building.

SUBSTANCE: inventions group relates to machine building. The vibration isolator contains casing with flange with two cone resilient bushings out of the wire material "Metal rubber"; clamping sleeve with hole for securing of the vibration-isolated object to the vibration isolator; cone support installed on the clamping sleeve; base on which casing is installed. The radial cross-section of bushings is hexagon with sides, antisymmetric relatively to its main diagonal, and rounded peaks. On the clamping sleeve a flange is made, the cone support rests in its end face. The cone cover is installed on smooth cylindrical part of the clamping sleeve and is centred on it. On the outside surface of the cone support a flat support platform is made. The axial tension of the resilient bushings is provided by tightening of the round nut installed on the thread end of the clamping sleeve. The axial tension crated in the resilient bushings is controlled by size between the flat end face of the cover and flat belt made on the external surface of the cone support, and the vibro-isolated object is secured to the vibration isolator using the screw inserted in the clamping sleeve and resilient washer. On the support surface of the casing flange the centring collar is made, and in the base a ring groove is made, in which the collar is installed, and base is centred as per its outside diameter. Method of the vibration isolator assemblage means consequential pressing of the resilient bushings in casing of the vibration isolator, control of the axial tension and securing on the assembled base detail.

EFFECT: decreasing of the dynamic loads on the object both in resonance, and in above resonance zones, and increasing of the vibration isolator service life.
