AI Technical Summary
The design of the rotor blade rim in existing aero-engines leads to assembly difficulties and stress concentration. The rhomboid rim is prone to jamming during assembly, difficult to disassemble, and has stress concentration at sharp corners.
The rotor blade rim plates are designed with inclined surfaces on both sides that are inclined along the blade mounting angle and planes parallel to the rotor disk axis. The rim plate edges are ground to ensure assembly without axial force, and the relative positions of the edge turning points are adjusted during assembly to avoid stress concentration.
This enables convenient assembly and disassembly of rotor blades on the rotor disk, avoids stress concentration, and improves the stability and reliability of the assembly structure.
