In einem Turbolader-Gehäuse 1 ist in einer Nabe 2 dieses Gehäuses 1 über eine Lagerbuchse 3 innerhalb dieser Nabe 2 eine Turbolader-Welle 4 gelagert. Fest mit der Welle 4 verbunden sind einenends ein Turbinenrad 5 und anderenends ein Verdichterrad 6. In der Zeichnung sind diese beiden Räder 5, 6 in einer Explosionsdarstellung in jeweils strichpunktierten Kreisen angedeutet.In a turbocharger housing 1 is in a hub 2 this case 1 via a bearing bush 3 within this hub 2 a turbocharger shaft 4 stored. Hard with the wave 4 connected are at one end a turbine wheel 5 and at the other end a compressor wheel 6 , In the drawing, these are two wheels 5 . 6 indicated in an exploded view in each dash-dotted circles.

Die Lagerbuchse 3 weist eine schwimmende Lagerung sowohl innerhalb der Nabe 2 als auch gegenüber der Welle 4 auf. Dabei ist die schwimmende Lagerung zwischen der Lagerbuchse 3 und der Nabe 2 eng begrenzt. Diese Begrenzung wird erzeugt durch einen Lagesicherungs-Stift 7. Dieser Stift 7 lagert in einer radial auf die Lagerbuchse 3 zu führenden Bohrung 8 innerhalb der Nabe 2. Aus der Bohrung 8 greift der Stift 7 in eine radiale Öffnung der Lagerbuchse 3 ein. Der Stift 7 ist als ein Hohlstift ausgeführt, damit durch dessen Hohlraum 9 Schmieröl unter Druck der Lagereinrichtung zugeführt werden kann.The bearing bush 3 has a floating bearing both inside the hub 2 as well as towards the wave 4 on. Here is the floating bearing between the bearing bush 3 and the hub 2 narrowly limited. This limit is generated by a position-securing pin 7 , This pen 7 superimposed in a radial on the bearing bush 3 to leading bore 8th inside the hub 2 , Out of the hole 8th grabs the pen 7 in a radial opening of the bearing bush 3 one. The pencil 7 is designed as a hollow pin, so through its cavity 9 Lubricating oil can be supplied under pressure to the storage facility.
