摘要： The invention relates to a rotor bearing system (1). Said system comprises a housing (80) in which a first permanent magnet (30) is mounted such that it can rotate about a first axis (105). A rotor (70) for conveying a liquid comprises a second hollow-cylindrical permanent magnet (40), which is mounted such that it can rotate about a second axis. The first permanent magnet (30) and the second permanent magnet (40) overlap axially at least partially, wherein the first permanent magnet (30) is disposed offset relative to the second permanent magnet (40). In the axial overlap region (160) of the first permanent magnet (30) and the second permanent magnet (40), the housing (80) is positioned between the two permanent magnets (30, 40). A first bearing (20) is configured for the relative axial positioning of the rotor (70) and the housing (80) with respect to one another and for receiving an axial force resulting from the arrangement of the first permanent magnet (30) and the second permanent magnet (40), and a second bearing (10) and a third bearing (90) are configured for receiving radial forces and for positioning the axis of rotation of the second permanent magnet (40).

摘要： The invention relates to an exhaust gas turbocharger having a hydrodynamic plain bearing or a hydrodynamic plain bearing, comprising a rotor (10) and a counter-bearing part (50) assigned to the rotor (10), wherein a rotor bearing surface of the rotor (10) and a counterface of the counter-bearing part (50) face each other to form the hydrodynamic plain bearing in the form of a combined journal—thrust bearing, having a continuous hydrodynamically load bearing gap formed between the rotor bearing surface and the counterface, wherein the rotor bearing surface and/or the counterface, when cut longitudinally and through the axis of rotation (R) in sectional view, form(s) a bearing contour forming merging contour sections (17.1 to 17.3; 44.1 to 44.3; 53.1 to 53.3) to generate hydrodynamic load capacities in both the radial and the axial direction, wherein a contour section (17.3; 44.3; 53.3) in sectional view in a first bearing area forms a linear section that is part of a, in particular cylindrical or partially cylindrical, bearing section rotating at least sectionally about the axis of rotation (R), wherein a further contour section (17.1; 44.1; 53.1), in sectional view in a second bearing area, forms a further linear section, which is part of a further bearing area rotating at least sectionally about the axis of rotation (R), wherein this further linear section forms an angle with the axis of rotation (R), and wherein the first and the second bearing area merge via a transition section. According to the invention, a friction-optimized bearing system is to be created, which is easy to manufacture and ensures a reliable and effective bearing arrangement even under highly dynamic loads. According to the invention, this is achieved by the further linear section forming an angle in the range from >30° to

摘要： an axial-radial sliding bearing (1) includes a first bearing ring (2) and a second bearing ring (4), the bearing rings being rotatable in relation to one another about a bearing axis A, and the second bearing ring (4) forming a substantially U-shaped cross-section in order to accommodate at least portions of the first bearing ring; and sliding elements (6) which are made of a polymer material and are arranged between the first and the second bearing ring in order to axially and radially decouple the bearing rings, the sliding elements (6) each having a substantially L-shaped cross-section with an axial region including axial sliding faces, and a radial region including radial sliding faces. At least one of the two bearing rings has a seat (7) for a detent element (8) which is accommodated therein, is force-loaded and deflectable, and the other of the two bearing rings has at least one detent recess (9) associated with the detent element for accommodating at least portions of the deflectable detent element (8) so as to provide a releasable locking action at a specified relative rotational position of the two bearing rings (2, 4) in relation to one another.
