VIBRATION ISOLATOR VPG AND PROCEDURE FOR ITS FABRICATION Russian patent published in 2015 - IPC F16F3/08 F16F1/362 

FIELD: machine building.

SUBSTANCE: inventions group relates to machine building. The vibration isolator contains two elastohysteresic bell-shaped elements out of the wire material "Metal rubber", which central holes contain two fixed bolts secured using the limiting washers and nuts. Each elastohysteretic element is made in form of two cones with smooth transition to each other or in form of a cylinder and top cone glued with each other. The elastohysteretic elements are wrapped with the reinforcement cord or cord pieces, over it the tensioned spiral is wound. The vibration absorber production method consists in the following. Two bell-like elements are made by chill pressing, and bolts are installed in their central holes. The elastohysteretic elements are glued to each other by large foundations, then they are wrapped with the reinforcement cord, and over cord the tensioned spiral is wound. In one contact layer of the turns are in planes parallel to the shaped surface, and in the another layer - in planes parallel to the frontal plane. The made billet is pressed, and bolts are secured in it. The central zone of the billet is pressed in radial directions, and top and bottom parts in direction of the vertical axis.

EFFECT: improved elastohysteresis properties, simplified design and assemblage process of the vibration isolator.
