CERAMIC STATIONARY BLADE SUPPORT STRUCTURE WITH SPACER

摘要

PURPOSE:To enable the heat resistance to be augmented by fitting a ceramic spacer in between a metal blade core arranged inside a hollow ceramic blade and an inner wall of the ceramic blade. CONSTITUTION:A metal blade core 4 is arranged in a hollow ceramic blade where an upper and a lower side walls 2 and 3 are fastened with a blade 1 holding the blade 1 between them. And a ceramic spacer 5 is fitted in between the inner wall of the blade 1 and the metal blade core 4. This configuration enables the blade 1 to be kept away directly from the blade core 4 while thermal transmission is restrained permitting the heat resistance to be augmented.
