DISPOSITIF D'ASSEMBLAGE D'UN ELEMENT CERAMIQUE A UN ELEMENT METALLIQUE, NOTAMMENT POUR TURBO-SURCOMPRESSEURS DE MOTEURS A COMBUSTION INTERNE

摘要

A metal-ceramic composite fitting assembly is described in which an effective connection between a boss on the ceramic member and the metal shaft member is achieved by providing the shaft with a sleeve formed of a material having a coefficient of thermal elongation comparable to that of the ceramic member, which sleeve is joined to the shaft member and cooperates with a recess therein to engage the boss along its length and to impose thereon compressive gripping forces that increase in magnitude along the length of the boss.
