According to embodiments described herein, an oil-cooled exhaust turbine apparatus is provided. The exhaust turbine apparatus comprises a rotatable shaft with a turbine wheel, a bearing member comprising a bearing, a bearing housing comprising a sealing bush portion for providing a first sealing device axially between the turbine wheel and the bearing member; an oil cooling chamber for cooling an inner face of the bearing housing, an oil channel for providing oil into the oil cooling chamber, an oil drainage chamber arranged axially between the bearing member and the sealing bush portion and an oil barrier wall surrounding, in at least a vertically top circumferential segment, a radially outer side of the oil drainage chamber for covering the oil drainage chamber from the oil cooling chamber.

Oil-cooled exhaust turbine apparatus

An exhaust turbocharger comprises a turbine having a turbine wheel and a compressor having a compressor wheel. The turbine wheel and the compressor wheel are connected by a shaft rotatably mounted in a bearing housing. A means for axially securing the shaft and the turbine wheel connected thereto is provided between the compressor wheel and the turbine wheel. The means limits an axial movement of the shaft and of the turbine wheel connected thereto in the direction of the turbine in the event of the compressor wheel bursting. The means comprises a component which is screwed onto the shaft during mounting and is fixed in the axial direction in the housing.
