AI Technical Summary
Current mechanical reducers in turbomachinery, particularly in aircraft turbofan engines, face issues with uneven loading and stress distribution on the sun gear teeth due to imbalances in force transmission, leading to manufacturing defects and flexibility challenges at the input shaft or interface.
Incorporating a solar element with an annular shape that includes two independent rings and an annular web connecting them, providing flexibility in both radial and axial directions through elastic deformation, allowing the rings to move relative to each other and absorb stresses during torque transmission.
This solution ensures a homogeneous distribution of loads on the sun gear teeth, reducing stress and manufacturing defects while maintaining operational efficiency and simplicity, compatible with various gearbox types and architectures.
