Abstract:
In a shaft composite structure wherein a ceramic shaft integrally formed with a ceramic turbine rotor is fixed to a metal sleeve integrally formed with a metal rotary shaft of a compressor impeller, a connection edge is located at a position corresponding to a recess for seal ring, and a thickness of tip portion of the metal sleeve is made thin to reduce a stiffness. Therefore, a stress concentration at the connection edge can be eliminated effectively and thus a reliable shaft composite structure can be obtained.
