| 摘要 |
The invention relates to a component having an annular or a tubular shape and the thermal inertia thereof is adapted to at least one adjacent component, in particular for a turbo machine. Said component comprises a first, radial inner element (3) and a second, radial outer element (4). Said first element (3) rests with the outer periphery thereof on the inner periphery of the second element (4) and both elements differ in at least one of their physical characteristic variables; expansion coefficient a, thermal conductivity ? and thermal capacity C in such a manner that the contact pressure between both elements (3, 4) increases when warmed and decreases when cooled. |
