The working mechanism of spherical hinge fusing structure was analyzed, the key dimensions were extracted, a simulation spherical hinge fusing mechanism was designed, and experimental verification was completed. It was found that the key parameters of the spherical hinge fusing device include fusing pin thin surface, pin material, and pin position. Its main roles should focus on reducing the angle of the second bearing through the relative slip of inner and outer rings of the inner bearing seat under the large unbalance, and protecting the second bearing. After the spherical hinge structure was fused, the stiffness was further weakened and the critical speed of the rotor was reduced, which reduced the critical speed of the engine when it decelerated to the windmill speed, and further reduce the unbalanced load in the case of beyond the critical rotating speed.
