Abstract
Fan blade assembly and shaft mounting in which there is minimized axial face run out or wobble of the rotating fan by virtue of the fan taking a perpendicularity signal from a shaft mounted hub plate which divorces the squareness of the fan shaft opening from influencing the hub plate perpendicularity signal. The fan is mounted on the motor shaft by a nut and Belleville spring assembly to provide end play takeup by the load deflection characteristic of the Belleville spring.
