Abstract

1. Виброизолятор, содержащий основание, упругие элементы и опорные узлы, упругие элементы выполнены плоскими в виде пакета верхних и нижних упругих элементов арочного типа, обращенных навстречу друг другу, причем каждый из пакетов выполнен в виде набора чередующихся во взаимно перпендикулярных направлениях плоских пружин, каждая из которых состоит из горизонтальной полки и двух боковых полок, отогнутых на угол 135° к горизонтальной полке и имеющих опорные участки на концах, а демпфирующий элемент виброизолятора выполнен комбинированным и состоит из фрикционной и эластичной частей, причем фрикционная часть выполнена в виде расположенных параллельно оси виброизолятора втулок с фланцами на торцах и отрезка троса, навитого по замкнутому контуру в плоскости, перпендикулярной оси виброизолятора на втулки, которые связаны с упругими элементами посредством заклепок, а эластичная часть выполнена в виде упругодемпфирующего кольца, охватывающего снаружи отрезок троса, навитого по замкнутому контуру в плоскости, перпендикулярной оси виброизолятора на втулки, в качестве материала кольца использован эластомер, например резина, полиуретан или комбинированный материал, в виде резинокордной оболочки, при этом установка эластичной части демпфирующего элемента виброизолятора осуществляется в статическом состоянии с натягом на фрикционную часть, отличающийся тем, что в качестве материала кольца использован упругодемпфирующий элемент, например рессорная сталь, при этом внутренняя поверхность кольца покрыта фрикционным материалом.2. Виброизолятор по п. 1, отличающийся тем, что внутренняя поверхность кольца покрыта фрикционным1. A vibration isolator containing a base, elastic elements and support nodes, elastic elements are made flat in the form of a package of upper and lower elastic elements of arch type facing each other, each of the packages being made as a set of flat springs alternating in mutually perpendicular directions, each of which consists of a horizontal shelf and two side shelves, bent at an angle of 135 ° to the horizontal shelf and having supporting sections at the ends, and the damping element of the vibration isolator is made combined consists of friction and elastic parts, and the friction part is made in the form of bushings located parallel to the axis of the vibration isolator with flanges at the ends and a cable segment wound in a closed loop in a plane perpendicular to the axis of the vibration isolator on the bushings that are connected to the elastic elements by rivets, and the elastic part made in the form of an elastic damping ring, covering the outside of the cable segment, wound in a closed loop in a plane perpendicular to the axis of the vibration isolator on the sleeve, as a material A ring elastomer, for example rubber, polyurethane or a combined material, in the form of a rubber-cord casing is used, while the installation of the elastic part of the damping element of the vibration isolator is carried out in a static state with an interference fit on the friction part, characterized in that an elastic-damping element, for example, spring, is used as the material of the ring. steel, while the inner surface of the ring is coated with friction material. 2. The vibration isolator according to claim 1, characterized in that the inner surface of the ring is coated with friction
