Abstract

Radialturbinhjul som omfatter et hjulelement (2) med generelt stumpkonisk eller likeverdig form, med en liten ende (3), en stor ende (4) og en sideflate (5), og blader (6) som rager radialt fra sideflaten (5) på hjulelementet (2), idet hjulet omfatter en aksial foriengelse (7) ved den lille enden (3) av hjulelementet (2), ragende utenfor et tverr- gående plan (8) ved enden av bladene (6), idet I det minste et parti av sideflaten (5) er dannet av en vegg (9), og et aksialt nav (10), idet det partiet av sideflaten (5) som er dannet av en vegg (9) og det aksiale navet (10) avgrenser en ringformet, aksial utsparing (11) ved den store enden (4) av turbinhjulet.Radial turbine wheels comprising a wheel element (2) of generally blunt or conical shape, having a small end (3), a large end (4) and a side surface (5), and blades (6) projecting radially from the side surface (5) of the wheel member (2), the wheel comprising an axial joint (7) at the small end (3) of the wheel member (2), protruding outside a transverse plane (8) at the end of the blades (6), with at least one a portion of the side surface (5) is formed by a wall (9) and an axial hub (10), the portion of the side surface (5) formed by a wall (9) and the axial hub (10) defining an annular , axial recess (11) at the large end (4) of the turbine wheel.
