Lock for moving blades of a turbine rotor |
摘要 |
A lock is provided for closing an entry point of a circumferential slot undercut on both sides and intended for accommodating blade roots of moving blades of a turbine rotor. A filling piece with a contour adapted to the blade roots is supported against a supporting side in the turbine rotor through the use of a fitting piece. A step provided in a base region of the lock serves to axially support the filling piece. The fitting piece may be provided with a slit into which a wedge for expanding the fitting piece can be pressed.
