Method of manufacturing ceramic turbo charger rotor.

摘要

In a method of manufacturing a ceramic turbo charger rotor (4), wherein an inner race (11) of an annular ball bearing and a spacer (12) are integrally secured to a journal portion (7) of a metal shaft (10) for connecting a ceramic turbine rotor (5,6) and a metal compressor rotor, the inner race (11) and the spacer (12) are press-fitted to the journal portion (7) of the metal shaft (10) while a tensile load is applied to the metal shaft (10).
