Rotor device for a jet engine with a disk wheel and several rotor blades

摘要

The present invention proposes a rotor device for a jet engine with a disk wheel and several rotor blades connected to said disk wheel, with the rotor blades being arranged in each case via a blade root substantially in the axial direction inside recesses of the disk wheel. Several locking segments are provided in the recesses of the disk wheel for axially locking the rotor blades, said locking segments interacting on the one hand with grooves of the rotor blades and on the other hand with at least one groove of the disk wheel. In the area of the groove of at least one of the rotor blades between the groove of the rotor blade and a locking segment there is a positive fit preventing a relative movement between the rotor blades and the locking segments.

主权项

1. A rotor device for a jet engine, comprising:
a disk wheel having a plurality of substantially axially oriented recesses and a locking ring groove; a plurality of rotor blades connected to the disk wheel, each rotor blade including a blade root positioned in one of the recesses, at least one of the rotor blades including rotor blade locking ring groove; at least one looking segment positioned between the disk wheel locking ring groove and the rotor blade locking ring groove for axially locking the at least one of the rotor blades, the at least one locking segment engaging the rotor blade locking ring groove in a defined contact area of the rotor blade locking ring groove to prevent relative movement between the at least one of the rotor blades and the at least one locking segment; wherein the rotor blade locking ring groove includes a tooth-shaped profiled body facing the at least one locking segment; wherein the profiled body includes a triangular area as viewed in an axial direction and the at least on locking segment includes a counterpart area as viewed in the axial direction, the profiled body triangular area forming a stop for the at least one locking segment counterpart area to prevent a relative circumferential movement between the at least one of the rotor blades and the at least one locking segment.
