Problems solved by technology

Due to non-optimized auxiliary conditions, such as lack of oil lubrication, too high oil temperature or too high thrust load in transient processing, the axial bearing will wear, which directly leads to a significant reduction in loading capacity, so reduce the axial bearing or combined Bearing capacity of axial / radial bearings

Embodiment Construction

[0026] according to Figure 1 to Figure 10 , the axial bearing 1 / axial / radial bearing 14 according to the invention, especially for an exhaust-gas turbocharger 2 , has a substantially disc shape or cylindrical shape with a first and a second side. Here, the axial bearing 1 / axial / radial bearing 14 has an oil groove 3 in the form of a circle segment, a wedge surface 4 bonded to the oil groove 3, a wedge surface 4 and a stop surface 5 arranged in sequence in the circumferential direction And in the form of a circle segment, the stop surface 5 engages the wedge surface 4 .

[0027] According to the invention, the stop surface 5 has an additional wear height H (see Figure 4 ), the additional wear height H can wear during the service life of the axial bearing 1 / axial / radial bearing 14 . In general, reference is made below only to the axial bearing 1 , wherein it is of course clear that the comments made about the axial bearing 1 can also be applied in the same way to the radial...

Abstract

The invention relates to an axial bearing (1) or a combined axial / radial bearing (14), especially for an exhaust-gas turbocharger (2), which has a substantially disc-shaped or cylindrical shape and has a centrally arranged Access opening (10) for the shaft, with: oil groove (3) in the form of a circular segment; wedge surface (4) joined to said oil groove in the form of a circular segment; stop surface (5), It engages the wedge face (4). Here it is important for the invention that the stop surface (5) has an additional wear height (H) which can be worn during the entire service life of the axial bearing (1), the inner flange (6) is arranged to extend in the form of a ring segment, configured as a sealing spoke (7), and the outer flange (8) is arranged to extend at least in the form of a ring segment, configured as a sealing spoke (9).

Description

technical field [0001] The invention relates to an axial bearing or a combined axial / radial bearing, especially for an exhaust-gas turbocharger, which has a substantially disc shape or a cylindrical shape. The invention also relates to an exhaust-gas turbocharger having at least one such axial bearing or such a combined axial / radial bearing. Background technique [0002] Due to the stricter exhaust regulations in the future, measures to reduce the CO of internal combustion engines are gradually being sought 2 emission. The current measure for this is to reduce consumption by downsizing / downsizing the exhaust turbocharging. The exhaust-gas turbocharger here usually has hydrodynamic slide bearings, classified as axial bearings and radial bearings. In order to be able to further reduce the CO of the turbocharged internal combustion engine 2 Emissions, especially in exhaust turbochargers, it is useful to optimize the installation of rotors. [0003] From WO 2011 / 154078 A1 a...
