Beschreibung
Zusammenfassung:	The invention relates to an exhaust-gas-driven turbocharger having a hydrodynamic plain bearing having a rotor and a stator, the rotor being rotatable with respect to the stator, the rotor bearing surface being located opposite a counter-surface of the stator in order to generate hydrodynamic pressure in the region of a converging gap. In such a hydrodynamic plain bearing, the application properties can be improved by the fact that the rotor bearing surface and/or the counter-surface constitutes in a section view, in the context of a section along and through the rotation axis, a continuous bearing contour that is constituted from convex or concave curvatures and/or from at least two contour segments that are embodied as straight lines and/or curvatures. The invention also relates to a hydrodynamic plain bearing or bearing arrangement having such a plain bearing.
