摘要： A hydrodynamic plain bearing having a stator and a rotor rotatable with respect to the stator, a rotor bearing surface being located opposite a counter-surface of the stator in order to generate hydrodynamic pressure. 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 at least two contour segments. The contour segments are suitable for generating hydrodynamic load capacity in a radial and axial direction. The contour segments are led into one another, by at least one transition segment, in such a way that hydrodynamic load capacity is generatable via the contour segments and the transition segment. The plain bearing is embodied as a multiple-surface plain bearing having two or more lubrication wedges in the region of the contour segments and of the transition segment.
