SPRING-TYPE VIBRATION ISOLATOR Russian patent published in 2015 - IPC F16F15/73 

FIELD: machine building.

SUBSTANCE: vibration isolator contains base, pole, resilient elements of spring type, and support-regulating and support assemblies. On the base the rod with thread end is rigidly secured, pole is installed on it. Pole secures on end of the resilient element by means of bevelled support elements and cover. The bevelled support elements are made resilient with stiffness exceeding stiffness of the resilient element. Support-regulating assembly is made as rigid spherical segment of the articulated support installed in the calibrated cylinder-cone hole made at free end of the resilient element. Spherical element in top part is rigidly connected with the thread rod to secure to it the support assemblies of the vibration isolated object. At bottom end the spherical element is connected with the rod with thread end, on which stop is secured. Clearance between the rod and cylindrical-cone hole of the articulated support is made depending on turning oscillations of the object with angle relatively to the rod axis.

EFFECT: increased efficiency of vibration isolation in resonance mode.
