Abstract
A connection for establishing a joint between materials having different coefficient of thermal expansion. The connection has a first and second members made from materials that have different coefficient of thermal expansion. The first member has a cylindrical end with a bore therein and a rib located on the peripheral surface of the cylindrical end. The second member has a first diameter section located in the bore of said first member and a second diameter section. A sleeve which surrounds a portion of the cylindrical end of the first member and the second diameter section of the second member has a groove for receiving the rib on the first member. Bolts extend through the sleeve into the second diameter section to establish an external compressive force between the sleeve and the rib to hold the first member and the second member in a fixed relationship and form a unitary structure. The first and second members responding to the differences in coefficient of thermal expansion with a reduction in said external compressive force while the first diameter section of the second member expands to create an internal radial force which acts on the portion of the first cylindrical member surrounding the bore to maintain the space relationship of the first and second members with changes in temperature.
