Abstract
Газовая силовая турбина с магнитной опорой, имеющая вал, электромагнитные подшипники и страховочные подшипники качения, отличающаяся тем, что вал силовой турбины выполнен двойным, состоящим из внешнего и внутреннего валов с воздушной межвальной полостью между ними, причем на переднем хвостовике внутреннего вала установлены диски турбины, а на заднем хвостовике - упругая муфта передачи полезной мощности, при этом на наружной поверхности внешнего вала установлены роторные элементы электромагнитных подшипников, а страховочные подшипники качения установлены на переднем и заднем хвостовиках внешнего вала, причем внешний вал зафиксирован относительно внутреннего вала в окружном направлении шлицами на заднем хвостовике, в радиальном направлении - радиальными ребрами, расположенными в межвальной воздушной полости, а в осевом направлении - опорными буртами, расположенными в межвальной воздушной полости, а также фланцем упругой муфты, при этом межвальная воздушная полость на входе через отверстия в заднем хвостовике внешнего вала соединена со станционной системой подачи холодного воздуха, а на выходе через каналы в стойках газовой турбины - с газовым трактом на выходе из турбины газотурбинного двигателя.A gas power turbine with a magnetic support having a shaft, electromagnetic bearings and safety rolling bearings, characterized in that the power turbine shaft is double, consisting of external and internal shafts with an air shaft between them, and turbine disks are installed on the front shaft of the internal shaft, and on the rear shank - an elastic clutch of useful power transmission, while on the outer surface of the outer shaft mounted rotor elements of electromagnetic bearings, and safety bearings the rolling elements are mounted on the front and rear shanks of the outer shaft, the outer shaft being fixed relative to the inner shaft in the circumferential direction by splines on the rear shank, in the radial direction by radial ribs located in the inter-shaft air cavity, and in the axial direction, by supporting collars located in the inter-shaft air cavity cavity, as well as the flange of the elastic coupling, while the inter-shaft air cavity at the inlet through the holes in the rear shank of the outer shaft is connected to the station supply system x lodnogo air and outlet channels through the gas turbine struts - a gas path downstream of the turbine of the gas turbine engine.
