Embodiment Construction

[0037] figure 1 and figure 2 A hydrodynamic plain bearing with a rotor 10 and a stator 20 is shown. For this purpose, a schematic sectional view along the rotor axis R of the rotor 10 is selected. The rotor 10 has a coupling piece 11 to which a bearing segment 12 is connected. A mechanical component such as a gear or the like can be indirectly or directly connected to the coupling piece 11 . The bearing segment 12 has a particularly rotationally symmetrical rotor bearing surface 13 . For this purpose, the rotor bearing surface 13 forms a continuous bearing contour in the direction of the rotational axis of the plain bearing. The support contour is formed by two contour sections 13.1, 13.2 and a transition section 13.3. In the invention, therefore, the distance of the bearing contour from the axis of rotation can vary along the axis of rotation (longitudinal center axis).

[0038] According to the invention and in particular according to figure 1 As shown in the variant...

Abstract

The invention relates to 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. In order to achieve improved utilization properties, provision is made according to the present invention 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 at least two contour segments; that the contour segments are suitable for generating hydrodynamic load capacity in a radial and axial direction; that the contour segments are led into one another, by means of at least one transition segment, in such a way that hydrodynamic load capacity is generatable via the contour segments and the transition segment; and that 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.

Description

technical field [0001] The invention relates to a hydrodynamic sliding bearing having a stator and a rotor rotatable relative to the stator, wherein the rotor bearing surface is opposed to a mating surface of the stator in order to generate hydrodynamic pressure. [0002] The invention also relates to a turbocharger with a hydrodynamic slide bearing. Background technique [0003] Rotatable mechanical elements such as shafts, rollers, gears or pump wheels require guidance in radial and axial directions in order to be able to transmit forces and torques. Hydrodynamic plain bearings can take on this task. The function of this bearing type is based on the physical principle of hydrodynamic pressure generation. In hydrodynamic plain bearings, a suitable lubricant is maintained between the rotor and the stator. During the rotational movement of the rotor relative to the stator, shear forces occur in the lubricant, which in this case cause the lubricant to be transported through...
