Title
(DE) Abgasturbolader mit einem hydrodynamischen Gleitlager oder hydrodynamisches Gleitlager
Abstract
(DE)

Abgasturbolader mit einem hydrodynamischen Gleitlager oder hydrodynamisches Gleitlager, mit einem Rotor (10) und einem dem Rotor (10) zugeordneten Gegen-Lagerteil (50), wobei sich eine Rotor-Lagerfläche (17.1, 17.2, 17,3) des Rotors (10) und eine Gegenfläche des Gegen-Lagerteils (50) gegenüberstehen, um ein hydrodynamisches Gleitlager zu bilden, wobei die Rotor-Lagerfläche und/oder die Gegenfläche bei einem Schnitt längs und durch die Rotationsachse (R) in Schnittansicht eine durchgehende Lagerkontur bildet/bilden, die wenigstens zwei ineinander übergehende Konturabschnitte (44.1 bis 44.3; 53.1 bis 53.3) bilden, um hydrodynamische Tragfähigkeiten sowohl in radialer als auch in axialer Richtung zu erzeugen, und wobei das Gegen-Lagerteil (50) in ein Lagergehäuse (60) oder ein Gehäuseteil eingebaut ist,. Um einen solchen Abgasturbolader mit einer kompakt bauenden und leistungsfähigen Lageranordnung mit einem hydrodynamischen Gleitlager bereitzustellen zu können, wobei gleichzeitig das hydrodynamische Gleitlager mit geringem Teileaufwand einfach zu montieren ist, ist es erfindungsgemäß vorgesehen, dass zwischen einer Außenkontur des Gegen-Lagerteils (50) und dem Lagergehäuse (60) oder dem Gehäuseteil ein, vorzugsweise umlaufender Spaltbereich (57) zur Bildung eines Quetschölfilms gebildet ist, wobei der Spaltbereich (57) mit einem Schmiermittel-Führungskanal (61) in räumlicher Verbindung steht, und dass sich der Spaltbereich (57) und die durchgehende Lagerkontur des Rotors (10) und/oder des Gegen Lagerteils (50) in Richtung der Rotationsachse (R) zumindest bereichsweise überdecken. embedded image
