Abstract
Description
Die Erfindung betrifft einen Abgasturbolader mit einem Turbinengehäuse, einem Verdichtergehäuse und einem Lagergehäuse, in dem eine Welle drehbar gelagert ist, wobei an einem ersten Ende der Welle ein im Turbinengehäuse drehbares Turbinenrad und an einem zweiten Ende der Welle ein im Verdichter drehbares Verdichterrad angeordnet sind, wobei das Lagergehäuse mit dem Turbinengehäuse und dem Verdichtergehäuse mittels Befestigungsmitteln verbunden ist und wobei zwischen dem Lagergehäuse und dem Turbinengehäuse Wärmeisolierungsmittel vorgesehen sind.The invention relates to an exhaust gas turbocharger with a turbine housing, a compressor housing and a bearing housing in which a shaft is rotatably mounted, wherein at a first end of the shaft, a turbine wheel rotatable in the turbine housing and at a second end of the shaft, a compressor wheel rotatable in the compressor are arranged, wherein the bearing housing is connected to the turbine housing and the compressor housing by means of fastening means and wherein thermal insulation means are provided between the bearing housing and the turbine housing.
Ein derartiger Abgasturbolader ist aus der
Die vorgeschlagenen Lösungen erweisen sich jedoch insbesondere hinsichtlich einer Wärmeisolierung der Gehäuseteile als äußerst aufwendig in der Herstellung. Eine Lösung gemäß der Ausführungsform gemäß
Es stellt sich daher die Aufgabe, einen Abgasturbolader zu schaffen, bei dem eine thermische Belastung des Lagergehäuses und damit der Lager verringert wird und der gleichzeitig kostengünstig und einfach herstellbar ist.It is therefore the object to provide an exhaust gas turbocharger, in which a thermal load on the bearing housing and thus the bearing is reduced and at the same time is inexpensive and easy to manufacture.
Diese Aufgabe wird dadurch gelöst, dass das Lagergehäuse und das Verdichtergehäuse Flanschorgane aufweisen, die mit einem Abstand D voneinander angeordnet sind und durch ein Spannorgan miteinander verbunden sind, wobei das Lagergehäuse und das Turbinengehäuse des Weiteren Klemmflächen vorsehen. Hierdurch wird auf einfache und kostengünstige Weise eine Wärmeisolierung der jeweiligen Flanschorgane gewährleistet. Das Vorsehen von Klemmflächen gewährleistet einen beabstandeten Wärmeübergang, wobei eine besondere Ausgestaltung der Klemmflächen eine zusätzliche Wärmeisolierung schafft.This object is achieved in that the bearing housing and the compressor housing have Flanschorgane, which are arranged with a distance D from each other and are interconnected by a clamping member, wherein the bearing housing and the turbine housing further provide clamping surfaces. As a result, thermal insulation of the respective flange members is ensured in a simple and cost-effective manner. The provision of clamping surfaces ensures a spaced heat transfer, with a particular embodiment of the clamping surfaces provides additional thermal insulation.
In einer vorteilhaften Ausführungsform ist zwischen Klemmflächen ein Hitzeschild eingepresst. Hierdurch ist es möglich, das Lagergehäuse zusätzlich vor Wärmestrahlung der heißen Bauteile der Turbinenseite zu schützen. Auch kann durch ein derartiges Hitzeschild der Wärmeübergang zwischen den Klemmflächen verringert werden, wenn zumindest ein Schenkel des Hitzeschildes, der zwischen den Klemmflächen eingeklemmt ist, eine wärmeisolierende Beschichtung aufweist. Eine verbesserte Wärmeisolierung kann darüber hinaus dadurch geschaffen werden, dass die Klemmfläche des Lagergehäuses aus mehreren Klemmteilflächen aufgebaut ist.In an advantageous embodiment, a heat shield is pressed in between clamping surfaces. This makes it possible to additionally protect the bearing housing from heat radiation of the hot components of the turbine side. Also, by such a heat shield, the heat transfer between the clamping surfaces can be reduced if at least one leg of the heat shield, which is clamped between the clamping surfaces, has a heat-insulating coating. An improved thermal insulation can also be created by the fact that the clamping surface of the bearing housing is constructed from a plurality of clamping part surfaces.
Besonders vorteilhafter Weise ist das Spannorgan als Spannband ausgeführt. Um die Flanschorgane und damit auch das Lagergehäuse und das Turbinengehäuse gegen ein Verdrehen zu sichern, ist es vorteilhaft, wenn die Flanschorgane mittels Stiftorgane gesichert sind.Particularly advantageously, the tensioning device is designed as a tension band. In order to secure the flange members and thus also the bearing housing and the turbine housing against rotation, it is advantageous if the flange members are secured by pin members.
Um eine einfache und damit kostengünstige Montage zu gewährleisten, weist das Lagergehäuse in vorteilhafter Weise eine Zentrierfläche auf. Dabei können die Zentrierfläche und die Klemmfläche als Lagergehäuseansatz ausgebildet sein.In order to ensure a simple and therefore cost-effective installation, the bearing housing advantageously has a centering surface. In this case, the centering surface and the clamping surface may be formed as a bearing housing approach.
Ein Ausführungsbeispiel eines erfindungsgemäßen Abgasturboladers ist in der Zeichnung dargestellt und wird nachfolgend beschrieben.An embodiment of an exhaust gas turbocharger according to the invention is shown in the drawing and will be described below.
Hierbei zeigt die einzige Figur einen Ausschnitt einer Schnittansicht eines Abgasturboladers mit einem Lagergehäuse und einem Verdichtergehäuse.Here, the single FIGURE shows a detail of a sectional view of an exhaust gas turbocharger with a bearing housing and a compressor housing.
