An Evaluation of the Usefulness of Two Math Models for Predicting Performance of a 100 mm Bore, Angular Contact, High Speed, Thrust Bearing.

Abstract

New designs for mainshaft thrust bearings for gas turbine engines are derived from mathematical and experimental analyses. The predictions of two bearing computer models, DREB and SHABERTH, being used by the Aero Propulsion Laboratory, were compared to experimental data generated by this study. This test bearing was a 100 mm bore, angular contact, ball bearing which was designed for R&D. Overall, the SHABERTH model was found to be a more practical tool for preliminary bearing design. However, DREB showed promise of being a valuable tool for diagnosing the dynamics of the bearing cage. This study also presents a new method for measuring three-dimensional kinematics of the bearing cage. A bibliography of the pertinent literature is included. (Author)
