Abstract

Die Erfindung betrifft das Gebiet des Energiemaschinenbaus und kann in Dampf- und Gasturbinen sowie in Axialverdichtern angewendet werden. Ziel der Erfindung ist eine Erhoehung der Vibrationssicherheit des Laufrades der Stroemungsmaschine. Neu an der Konstruktion des Laufrades der Stroemungsmaschine ist, dass an der Wand jeder Nut oder am Draht Vorspruenge ausgebildet werden, wobei die Laenge eines Vorsprungs 0,05 bis 0,3 der Nutlaenge betraegt. Die Nutwaende sind zur Laufradmitte unter einem Winkel geneigt, der kleiner als 45 ist.The invention relates to the field of energy engineering and can be applied in steam and gas turbines as well as in axial compressors. The aim of the invention is an increase in the vibration safety of the impeller of the flow machine. What is new about the design of the impeller of the blasting machine is that protrusions are formed on the wall of each groove or on the wire, the length of a protrusion being 0.05 to 0.3 of the groove length. The Nutwaende are inclined to the wheel center at an angle which is less than 45.
