AI Technical Summary
Existing technologies have low precision in adjusting the shims when controlling the axial distance between the compressor rotor and stator, which affects the support quality of the rotor and leads to a decrease in engine assembly performance.
An axial adjustment device is adopted, including rigid and flexible adjustment pads. By adjusting the thickness, number of layers and elastic change rate of the adjustment pads, the axial distance between the rotor and stator is precisely controlled, avoiding changes in the rotor's support state and improving sealing and concentricity.
It achieves precise control of the axial distance between the rotor and stator, improves the engine's assembly performance and sealing, and increases the engine's first-time assembly pass rate.
