Abstract (en)

[origin: EP1134359A2] The turbine blades fit to form-lock in an undercut slot(2) in the rotor(1) and are fixed by a blade locking piece. The locking piece consists of an start point(7) in communication with the slot and in which a filling piece(8), form-locking with the blade root, and a key are fitted. The cross section of the start point accommodating the filling piece widens out conically starting from the blade slot. The cross section of the filling piece matches the cross section of the start point. An Independent claim is included for a procedure for the manufacture of the proposed blade lock.
