Abstract
1. Пружинный равночастотный виброизолятор, содержащий основание, опорную платформу и расположенный между ними упругий элемент, выполненный в виде цилиндрической равночастотной пружины, имеющей переменный шаг t, обеспечивающий постоянство собственной частоты системы при любых нагрузках Р из заданного диапазона: P≤Р≤Р, за счет своей осадки δ:где Pи Рсоответственно минимальная и максимальная нагрузки, при которых сохраняются условия равночастотности; Р - нагрузка, удовлетворяющая условию P≤P≤Р;δ- заданная начальная осадка пружины, отвечающая минимальной нагрузке P, и условию равночастотности: постоянству частоты собственных колебаний виброизолируемой системы при изменении массы этой системы в заданных пределах, отличающийся тем, что на опорной пластине виброизолятора верхнего фланца равночастотной пружины закреплен виброизолируемый объект с переменной технологической массой, а нижний фланец равночастотной пружины виброизолятора закреплен на упругом основании, которое посредством, по крайней мере, трех стоек с винтами и с коаксиально расположенными снаружи стоек эластичными втулками соединено с нижней платформой виброизолятора, а под упругим основанием нижнего фланца равночастотной пружины, осесимметрично ей, размещен цилиндроконический демпфер, например из эластомера, установленный своей цилиндрической частью на нижней платформе каждого виброизолятора, а коническая часть связана с упругим основанием равночастотной пружины.2. Пружинный равночастотный виброизолятор по п.1, отличающаяся тем, что цилиндроконический демпфер выполнен в виде последовательно соединенных конической и цилиндрическо�1. A spring-loaded equal-frequency vibration isolator containing a base, a support platform and an elastic element located between them, made in the form of a cylindrical equal-frequency spring having a variable pitch t, ensuring the constancy of the natural frequency of the system at any loads P from a given range: P≤P≤P, for account of its precipitation δ: where P and Р respectively the minimum and maximum loads under which the conditions of equal frequency are maintained; P is a load satisfying the condition P≤P≤P; δ is a given initial spring draft corresponding to the minimum load P and the condition of equal frequency: constant frequency of natural vibrations of the vibration-insulated system when the mass of this system changes within specified limits, characterized in that on the support plate the vibration isolator of the upper flange of the equal-frequency spring is fixed to a vibration-isolating object with a variable technological weight, and the lower flange of the equal-frequency spring of the vibration isolator is fixed to an elastic base, which ohm of at least three struts with screws and with elastic bushings coaxially located outside the struts is connected to the lower platform of the vibration isolator, and under the elastic base of the lower flange of the equal-frequency spring, axially symmetrical to it, is placed a cylindrical damper, for example from an elastomer, mounted with its cylindrical part on the lower the platform of each vibration isolator, and the conical part is connected with the elastic base of the equal-frequency spring. 2. Equal spring vibration isolator according to claim 1, characterized in that the cylindrical damper is made in the form of conically and cylindrically
