• The shrink fit between a ceramic shaft and a metal ring with the use of a bimetal shrink fitter has been developed in this paper. The fitting strengths of the shrink-fitted assemblies were measured from room temperature to 600℃. The contact pressures between the shafts and the shrink fitters of bimetal were also calculated. The ceramic shaft was Al_20_3 or Si_3N_4. The shrink fitter was a bimetal of SUS304 and SUS403. The outer ring was SUS403. It was shown from the calculations that the shrink-fitted assembly using the bimetal shrink fitter was somewhat weaker than that using the monolithic SUS304 shrink fitter when the thickness of the shrink fitter in the radial direction was over 6 mm. The shrink-fitted assembly using the bimetal shrink fitter was approximately 3MPa stronger than that using the monolithic SUS304 shrink fitter at 600℃ when the thickness of the shrink fitter in the radial direction was 4 mm. The fitting conditions under which the shrink-fitted assembly using the bimetal shrink fitter was stronger than that using the monolithic SUS304 shrink fitter were discussed.
