Abstract

PURPOSE: To improve durability and reliability by so setting the outer diameter of a connecting shaft projectively formed on a ceramic rotor as to satisfy a specific condition and coupling the shaft to a metal rotary shaft only through the recessed bearing shaft part in said metal shaft corresponding to the rotor.
CONSTITUTION: A connecting shaft 12 is monolithically formed with the shaft center part of a ceramic rotor 11 and the connecting shaft 12 is coupled to the recess 15 of a metal rotary shaft 13. In this case, the connecting shaft 12 and the metal rotary shaft 13 are kept in a non-contact state at a corresponding part having a circular groove 16 for fitting a seal ring for the recess 15 and coupled to each other at the corresponding part of a shaft part 14 for the bearing of the recess 15. And the outer diameter 'l1' of the connecting shaft 12 for the maximum outer diameter 'L1' of the ceramic rotor 11 is made to satisfy the relations of l1(mm)≥0.07×L1(mm)+4.2, where 40mm≤L1≤150mm and further to cover 80W90% of the outer diameter 'l2' of the bearing shaft part 14, thereby preventing the fracture and similar damage of connected part due to an eccentric stress arising from rotation at high speed and high temperature.
