Abstract
This disclosure generally relates to an integral superstructure for supporting a rotating shaft connected to a rotor relative to a stator. The integral superstructure supports the rotating components. The superstructure includes a bearing portion that contacts the shaft. The stator portion is radially spaced outward from the rotor by a critical dimension. A first annular transfer portion extends axially forward from the bearing to the stator portion. A second annular transfer portion extends axially rearward from the stator portion to a mounting flange. The mounting flange connects the superstructure to a frame. As the temperature of the superstructure increases, the superstructure maintains the critical dimension between the rotor and stator. The rotor may be a compressor impeller in a gas turbine engine, and the stator may be an aerospace component that delivers air to a combustor.
