Description
Изобретение относитс к .камп|рёссб;росГрй ё, иию.This invention relates to .camps | ressb;
Известны роторы с измен ющейс в .процессе работы 1собствен«ой частотой колебаний, содержащие вал с дисками.There are known rotors with varying frequency of oscillation in the process of their own, containing a shaft with disks.
Предлагаемый рото-р отличаетс от известных тем, что соединение пе реднего вала с барабаном ротора производитс через гнб.кую обечайку диска второй ступени. Дл ограничени прогиба ipoTqpa на диске второй сту:пени установлено распорное колъи.0.The proposed roto-p differs from the known ones in that the front shaft is connected to the rotor drum via a second stage disc shell. To limit the deflection of the ipoTqpa on the disk of the second stu: spacer, a spacer 0 is installed.
Это обеспечивает надежность ротора при прохождении критических оборотов -и ограничивает его прогиб.This ensures the reliability of the rotor during the passage of the critical speed - and limits its deflection.
На чертеже изображен предлагаемый ротор, разрез по оси.The drawing shows the proposed rotor, a section along the axis.
Передний вал с диском ./ первой ступени помощи болтов 2 соедин етс с гибкой обечайкой 3 диска 4 второй ступени. На посадочный по сок 5 диска второй установлено раоиорное кольцо 5.The front shaft with the disk ./ of the first stage of the aid of the bolts 2 is connected to the flexible shell 3 of the disk 4 of the second stage. On the juice of 5 landing disk, the second set is a radio ring 5.
Между торцом распорного кольца и диском первой ступени имеетс небольшой осевой зазор а, величина .которого подб ираетс таким образом, чтобы он выбиралс при прохождении критических оборотов pOTqpa и восстанавливалс в процессе дальнейшего иовышенн его оборотов.Between the end of the spacer ring and the first-stage disc there is a small axial clearance a, the value of which is selected so that it is selected during the passage of the critical pOTqpa revolutions and restored in the process of further elevation of its revolutions.
