HYBRID EXHAUST TURBINE SUPERCHARGER

摘要

A hybrid exhaust gas turbocharger is provided, which is capable of preventing the supercharger from being damaged due to a rotary shaft being moved to a large extent in an axial direction by vibration generated from the internal combustion engine and a rotary portion in contact with a stationary portion in the supercharger when the supercharger is mounted on an internal combustion engine. A restraint mechanism (35) including a thrust collar (41) attached to a shaft end of a rotary shaft (19a) of a generator positioned on a side opposite to a flexible coupling and two thrust bearings (42) disposed to oppose both end surfaces forming a flange portion (44) of the thrust collar (41) is accommodated in a recess (51) formed on a front surface side of a shell housing positioned on a side opposite to the casing.
