Abstract

1. Тарельчатый виброизолятор с шарнирами угловых перемещений, содержащий каркас, упругие элементы, верхнюю платформу для установки виброизолируемого объекта и нижнее основание для крепления упругих элементов, отличающийся тем, что каркас выполнен в виде верхней платформы для установки виброизолируемого объекта посредством, по крайней мере, трех упругих элементов, например в виде винтовой цилиндрической пружины, которые крепятся к верхней платформе каркаса виброизолятора и к основанию виброизолируемого объекта, в центральной части платформы выполнено резьбовое отверстие, осесимметрично которому расположен сферический шарнир, выполненный в виде сферы, на параллельные поверхности которой опираются тарельчатые пружины, причем параллельные поверхности отстоят от диаметральной плоскости сферы на одинаковое расстояние, необходимое для фиксации ее в упругих элементах, например, в виде тарельчатых пружин, при этом в паре с тарельчатыми пружинами, контактирующими со сферой, работают соответственно тарельчатые пружины, одна из которых жестко соединена с платформой, а другая посредством контргайки винта - с основанием, а в верхней части сферический шарнир крепится посредством винта с буфером на конце к верхней платформе для установки виброизолируемого объекта, а в нижней посредством винта - к основанию, выполненному в виде днища стакана каркаса виброизолятора, причем головки винтов расположены во внутренней полости сферы с возможностью отслеживать угловые колебания верхней платформы с виброизолируемым объектом, а для фиксации предельных значений угловых перемещений верхней платформы с виброизолируемым объектом1. A plate vibration isolator with hinges of angular displacements, comprising a frame, elastic elements, an upper platform for mounting a vibroinsulated object and a lower base for attaching elastic elements, characterized in that the frame is made in the form of an upper platform for installing a vibroisolated object by at least three elastic elements, for example in the form of a coil spring, which are attached to the upper platform of the vibration isolator frame and to the base of the vibration-insulated object, in the central part of the pl of the mold, a threaded hole is made, axisymmetrically to which there is a spherical hinge made in the form of a sphere, on which parallel disk springs rest, parallel surfaces being spaced from the diametrical plane of the sphere by the same distance necessary for fixing it in elastic elements, for example, in the form of disk springs while paired with Belleville springs in contact with the sphere, Belleville springs operate respectively, one of which is rigidly connected to the platform, and the other first, by means of a screw locknut, with a base, and in the upper part, the spherical hinge is fastened by means of a screw with a buffer at the end to the upper platform for installing a vibration-insulated object, and in the lower part by means of a screw, to the base, made in the form of the bottom of the glass of the vibration isolator frame, and the screw heads are located in the inner cavity of the sphere with the ability to track the angular vibrations of the upper platform with a vibration-insulated object, and to fix the limiting values of the angular displacements of the upper platform with vibration-insulated object
