Gas turbine i.e. flight gas turbine, for engine of e.g. jet, has circular seal element including outer ring at axial side and thread at opposite axial side, where thread of circular seal element is screwed on thread of high pressure shaft

摘要

The turbine has a high pressure shaft (4) and a low pressure shaft (7) that is concentrically supported in the high pressure shaft. A hydraulic seal (6) is arranged in an area of a bearing chamber (16), and includes a circular seal element (1), which exhibits an outer ring (8) at an axial side, and is provided with a thread at an opposite axial side, where the thread is screwed on a thread of the high pressure shaft. The seal element is formed for applying axial pre-tensioning force on additional axle components (2, 3).
