High-speed dynamic balance bearing swing frame for aero-engine rotor

The utility model provides a high-speed dynamic balance supporting swing frame for an aero-engine rotor. The high-speed dynamic balance supporting swing frame mainly comprises a basic rigidity frame, an upper tile cover, a swing frame body, a T-shaped section clamping seat, an additional rigidity plate spring, an axial rigidity rod, a vibration measuring sensor and the like. The basic rigidity frame is of an integral type and is composed of a bearing seat lower tilting fillet, a supporting rod spring and a basic rigidity frame bottom support, the supporting rod spring is of a variable cross-section structure, and the compression resistance stability is improved. The additional rigidity plate spring meets the variable rigidity requirement of the bearing swing frame. The axial stiffness rod forms the axial stiffness of the tilting fillet and the torsional stiffness around the vertical axis and the horizontal axis. The high-speed dynamic balance supporting swing frame for the aero-engine rotor is suitable for a
