SPRING VIBRATION ISOLATOR Russian patent published in 2016 - IPC F16F15/73 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Vibration isolator contains base, pole, resilient elements of spring type, as well as support-regulating and thrust units. 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 beveled support elements and cover. Beveled support elements are made resilient with stiffness exceeding stiffness of 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 thread rod to secure to it support assemblies of vibration isolated object. At bottom end spherical element is connected with rod with thread end, on which stop is secured. Gap between rod and cylinder-taper hole hinged support is performed at rotary oscillations of object with an angle relative to rod axis. Along base there are stiffening ribs in form of two jibs. Spherical element is made of friction material.

EFFECT: higher efficiency of vibration isolation in resonance mode.
