Abstract: A turbocharger (10) includes a compressor wheel (32) and shaft assembly in which a threaded connection is provided between the shaft (18) and the compressor wheel (32). A pair of pilot surfaces (76, 78) on the shaft (18) and on the compressor wheel are located on either end of the threaded sections (64, 66) of the shaft and compressor wheel, and are displaced radially from the threads (64, 66). Accordingly, the piloting functions which assure concentricity between the shaft (18) and compressor wheel (32) are kept entirely separate from the attachment function provided by the threads (64, 66), thereby permitting the concentricity between the compressor wheel (32) and shaft (18) to be held to tighter tolerances than would be possible if the threads (64, 66) also performed a piloting function.

Abstract: The invention relates to a turbine shaft (1) intended in particular for a steam turbine aligned along an axis (2) of rotation. The turbine shaft (1) has a first region (4) of maximum radius R1 and a second region (5) bordering on the first and of maximum radius R2 > R1. The first region (4) has a first base material for use at temperatures of over 550 DEG C and the second region (5) has a second base material for use at temperatures of below 550 DEG C. The steel alloy used for the first and second base material has a chromium content of between 8.0 and 12.5 wt.% respectively, the austenitization temperature being substantially the same in each case.

Abstract: An improved compressor wheel assembly for a turbocharger or the like includes a centrifugal compressor wheel having a boreless hub to substantially improve wheel fatigue life. The compressor wheel is formed as by casting to include an integral and internally threaded mounting sleeve extending coaxially from the boreless hub. In the assembly, the mounting sleeve extends through an opening in a compressor backplate for threaded connection to a turbocharger shaft, with a thrust collar spacer being interposed between axially facing shoulders defined respectively on the mounting sleeve and shaft to ensure accurate axial positioning of the components. An annular seal flange on the thrust collar spacer extends axially into the backplate opening in generally concentric spaced relation about the mounting sleeve. This seal flange is adapted to carry one or more seal rings for engaging the backplate, thereby sealing the passage of the mounting sleeve and shaft through the backplate opening.
