Figure 2 is a side sectional view of the ceramic rotor, which is an enlarged view taken from the ■-■ arrow in Figure 1, Figure 3 is a schematic front view of a ceramic rotor whose rotor shaft is made of metal, and Figures 4, 5, and 6 are of the present invention. 1 is a schematic front view showing an embodiment of a ceramic rotor according to the present invention. In Figures 4 to 6, 121 (or 31 or 41) is a rotor shaft made of a material having a coefficient of thermal expansion equal to N with the ceramic material, 122 (or 32 or 42) is an impeller made of ceramics, and 123 (or 33 or 43)
is a ceramic blade, 124 (or 34.36
Or 44.46) is the shrink fit part, 35 (or 45)? Well, it's the intermediate axis.

Claims

[Scope of utility model registration request]

A Tarzen rotor characterized in that an impeller made of a ceramic material and a rotor shaft made of a metal material having approximately the same coefficient of thermal expansion as the ceramic material are integrally coupled by shrink fit.
