Abstract (en)
The bolt (1) has bi-conical profile or conical ends (3) that are automatically centered into a receiving bore (4) of respective turbine blades (2) in order to couple the turbine blades adjacent to each other. The bolt is partially manufactured from composite material such as steel and/or titanium. The bolt is rotationally symmetrically formed as a hollow profile. The receiving bore is formed as through hole or a blind bore by forming the turbine blades with thickened portion (5).
Abstract (de)
Die Erfindung betrifft einen Koppelbolzen (1) zum Koppeln von zwei oder mehreren Turbinenschaufeln (2), wobei die Koppelbolzen (1) zumindest teilweise aus Faserverbundwerkstoff bestehen. Durch die zumindest teilweise Ausbildung aus Faserverbundwerkstoff kann das Gewicht der Koppelbolzen (1) gegenüber im Stand der Technik deutlich herabgesetzt werden.
