Rotor Dynamics and Bearing Investigations for A 10 KW Turboalternator Unit 710566

A combined analytical and experimental approach in the development of an advanced 10 kw turboalternator rotor and bearing system is described. Considerations leading to the selection of oil squeeze film damped angular contact bearings are reviewed. Unbalance response of the rotor system is covered along with a case of bearing excited fractional frequency whirl. The capabilities of the rolling element bearings are discussed, and the effects of bearing design details on fatigue life are summarized.
