Abstract
The present invention includes an overhung turbine wheel which is provided with at least one ring of turbine blades and is connected with a shaft. In order to control the thermodynamically required circumferential speeds necessary to achieve maximum efficiency, the turbine wheel is designed as a closed disk which is narrow in the axial direction. The turbine wheel is integral with the turbine blades and furthermore is connected to the shaft through planar connecting surfaces having interfitting teeth. The turbine wheel has a relatively low mass, and the interfitting teeth allow a simple and optimal centering connection. Radial-flow turbines of this kind are standardized in model series, the turbine wheels and shafts in each case being provided with similar interfitting teeth to allow mutual combinations as desired.
