Definitions
- the invention relates to an exhaust-gas turbocharger as per the preamble of claim
- an exhaust-gas turbocharger of the generic type has a bearing unit, which is also referred to as a bearing cartridge or bearing insert. Cartridges of this type can be used both in plain bearing systems and for systems mounted on rolling bearings.
- Fixing elements serve to retain the bearing cartridge in position within the bearing housing, the position retainment against axial displacement of the cartridge and the retainment of the cartridge against twisting in the bearing housing being performed by separate fixing elements arranged, for example, at the ends of the bearing cartridge.
- the fixing element of the exhaust-gas turbocharger according to the invention is formed on the basis of the so-called "keyhole principle", which makes it possible to provide merely a single fixing element in the bearing housing, which secures the bearing cartridge both against axial displacement and also twisting.
- a latching lug is provided in the fixing element and interacts with a corresponding latching recess of the bearing cartridge, and thus forms the anti-twist means between the cartridge and the fixing element.
- the bearing housing cover is utilized as a pretensioning element.
- the bearing housing cover serves as a pretensioning element.
- the bearing housing cover can be utilized as a positioning aid and anti-twist means. In this respect, it is preferable to provide either screws or stay bolts, which interact with boreholes or threaded boreholes in the bearing housing and in the fixing element.
- Claims 7 to 9 define the method according to the invention.
- Figure 1 shows a schematically simplified illustration of an exhaust-gas turbo charger according to the invention
- FIG 2 shows a schematically slightly simplified perspective illustration of a bearing housing of the exhaust-gas turbocharger shown in Figure 1,
- Figure 3 shows a perspective illustration of a fixing element according to the invention
- Figures 4 A to 4F show illustrations of a bearing cartridge and of the fixing element and also of the bearing housing for explaining the sequence of the assembly steps of the assembly method according to the invention.
- Figure 1 shows an exhaust-gas turbocharger 1 according to the invention, which has a turbine 2 and a compressor 3.
- a turbine 2 for simplification of the illustration, neither the compressor housing nor the turbine housing are shown, since these parts are not required for explaining the principles of the present invention.
- bearing housing 4 For mounting a charger or rotor shaft 16, provision is made of a bearing housing 4 between the compressor 2 and the turbine 3, in which bearing housing a bearing cartridge 5 for the rotor shaft 16 is arranged.
- the bearing cartridge 5 can be formed in this respect both as a plain bearing arrangement and as a rolling bearing arrangement.
- a fixing element 6, which in Figure 2 is shown in the state in which it is assembled in the bearing housing 4.
- the fixing element 6 encompasses the bearing cartridge 5 and is secured with respect to the bearing housing 4 by an anti-twist means, which, in the exemplary embodiment illustrated, comprises two anti-twist screws 14 and 15, which are inserted into two associated boreholes 12 and 13 in the fixing element 6, which can be seen in Figure 3.
- the fixing element 6 has an annular main body 17, which is provided on both sides with two widened body portions 18 and 19 in which the boreholes 12 and 13 are arranged, as is apparent in detail in particular from Figure 3.
- An insertion recess 8 with an associated diameter Ds and a holding recess 9 with an associated diameter Dg are also arranged in the body 17. As shown in Figure 3, the insertion recesses 8 and the holding recesses 9 merge into one another, in order to be able to receive the bearing cartridge symbolized, in Figure 3, by the dashed circle 5.
- Figure 3 furthermore shows that, as per the illustration chosen in Figure 3, a latching lug 10 is provided on the bottom of the holding recess 9 and interacts with a latching recess 1 1 , visible in Figure 4B for example, of the cartridge 5, the interaction arising, for example, from Figure 2, which shows the assembled state.
- a latching lug 10 is provided on the bottom of the holding recess 9 and interacts with a latching recess 1 1 , visible in Figure 4B for example, of the cartridge 5, the interaction arising, for example, from Figure 2, which shows the assembled state.
- bearing housing cover 7 is fastened to the bearing housing 4, which holds the entire system in position axially in the bearing housing 4.
