Exhaust-gas turbine for turbocharger, has rotor blades arranged in outer circumference of rotatably supported turbine disk, and thermal insulation arranged between inner circumferential surface of guide ring and hollow space

摘要

The turbine has rotor blades (1.2) arranged in an outer circumference of a rotatably supported turbine disk (1) in order to subject with exhaust gas. A guide ring includes stator blades (2.1) in a flow direction of the exhaust gas of the disk in order to guide the exhaust gas to the rotor blades. A hollow space (4) is formed in the flow direction of the exhaust gas in front of the turbine disk. Thermal insulation (3.1) is arranged between an inner circumferential surface (2.2) of the guide ring and the hollow space.
