Locking device for turbine blades |
摘要 |
A turbine blade locking device axially retains a turbine blade ( 1 ) inserted in an axial, profiled slot ( 10 ) of a turbine disk ( 6 ). The turbine disk ( 6 ) is provided with a locking groove ( 8 ) passing through the slot ( 10 ) and extending radially in the plane of the turbine disk ( 6 ). A locking pin ( 4 ) is inserted in the locking groove ( 8 ) and the blade root ( 3 ) is provided at its bottom side with a notch ( 9 ) aligning with the locking groove ( 8 ). A portion of an elastic element ( 5 ) is arranged radially below the locking pin ( 4 ) to pre-load the locking pin ( 4 ) in a radially outward direction and into the notch ( 9 ).
