Abstract
Изобретение относитс к гидромашиностроению и позвол ет повысить надежность креплени рабочего колеса турбомашины. Ступица 3 установлена на валу 2 посредством шлицевого соединени с демпфером 5 и ее внутренн поверхность 7 выполнена вогнутой. Конец вала 2 снабжен втулкой 8 с наружной конической поверхностью 9. Соединение выполнено в виде упругого кольца, охватывающего вал 2 и поверхность 7. Фиксатор 6 осевого положени колеса 1 выполнен в виде гайки 11, прижимающей втулку 8 к кольцу. Радиальные вибрационные перемещени колеса 1 воспринимаютс демпфером 5, обеспечива виброизол цию вала 2. 2 ил.The invention relates to hydraulic machine building and makes it possible to increase the reliability of fastening the impeller of a turbomachine. The hub 3 is mounted on the shaft 2 by means of a spline connection with the damper 5 and its inner surface 7 is made concave. The end of the shaft 2 is provided with a sleeve 8 with an outer conical surface 9. The connection is made in the form of an elastic ring encompassing the shaft 2 and the surface 7. The latch 6 of the axial position of the wheel 1 is made in the form of a nut 11, which presses the sleeve 8 to the ring. Radial vibratory movements of the wheel 1 are perceived by the damper 5, providing vibration isolation of the shaft 2. 2 sludge.
