Abstract
Gas dynamic bearing (GDB) has been extensively utilized in micro high-speed rotating machinery. However, the majority of existing research has been confined to conventional air environments. This study aims to address this gap by conducting a comprehensive investigation. Firstly, we compare and monitor the friction/wear characteristics between the bump foil strip and the top foil strip. Secondly, we explore the stiffness characteristics of the elastic support structure in GDB. Additionally, we examine the static and dynamic bearing performance of GDB in both oxygen-free and conventional air environments. Results reveal that in an oxygen-free atmosphere, the friction coefficient between the bump foil strip and the top foil strip, the stiffness of the elastic support structure, the load-carrying capacity, and the dynamic bearing stiffness of GDB are significantly higher than those observed in conventional air environment.
期刊介绍：
Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
