Embodiment Construction

[0030] according to figure 1 , figure 2 as well as Figure 4 to Figure 6 The charging device 1 according to the invention, which can be formed, for example, as an exhaust-gas turbocharger 2 , has a bearing housing 3 and a shaft 4 supported therein and shown only schematically. Also provided is an axial bearing disc 5 for supporting the shaft 4 in the axial direction 6 (see also image 3 as well as Figure 7 to Figure 9 ). The receptacle 7 of the axial support disc 5 is thus arranged in the support housing 3 , wherein the receptacle 7 has a single lug 9 protruding inwards to the axis 8 , while the axial support disc 5 has complementary formed lugs 9 to the bearing housing side. The side of the edge is recessed 10. The lugs 9 and the recesses 10 are thus formed and / or aligned in such a way that they only allow a single, ie predefined, mounting position of the axial bearing disc 5 in the socket 7 of the bearing housing 3 . It is self-evident that in the opposite form, for ...

Abstract

The invention relates to a supercharging device (1), in particular to an exhaust-gas turbocharger (2) comprising a bearing housing (3) and a shaft (4) supported in the bearing housing, comprising an axial bearing disk (5) for supporting the shaft (4) in an axial direction (6). It is thus necessary for the invention that a socket (7) is provided for the axial bearing disk (5), the socket (7) has asingle lug (9) projecting radially inward to the axis (8), and the axial bearing disk (5) has an edge-side recess (10) formed complementarily to the bearing housing-side lug (9); the lugs (9) and therecesses (10) are formed and / or aligned in such a way that they are aligned and allow only a single predefined mounting position of the axial bearing disk (5) in the socket (7).

Description

technical field [0001] According to the preamble of claim 1 , the invention relates to a charging device, in particular an exhaust-gas turbocharger, comprising a bearing housing and a shaft supported therein. The invention also relates to an axial support disk for a charging device of this type. Background technique [0002] The axial support disk in the supercharging device serves the purpose of axially supporting the shaft and thus for interference-free operation of the supercharging device. In response to assembly, an axial bearing disc of this type is assembled so as to be fixed against rotation in the bearing housing, wherein inadvertent incorrect mounting is anyway to be avoided. [0003] From DE 1155942 B is known a supercharging device comprising a bearing housing and a shaft supported therein, wherein the shaft is supported in the axial direction via an axial bearing disc. The axial bearing disc is thus fixed in a rotationally fixed manner in the bearing housing v...
