Abstract: Epicyclic gears, also commonly referred to as planetary gears, are power transfer components that are commonly used in several industrial applications. The structural compliance of thin-rimmed annular ring gear can ...

Abstract: The structural compliance of annular ring gear can significantly influence the quasi-static and dynamic performance of an epicyclic gear set. As powertrain components are continually being optimized to their design limits, ...

Abstract: A new fluid dynamics model is proposed to predict the power losses due to pocketing of air, oil, or an airoil mixture in the helical gear meshes. The proposed computational procedure treats a helical gear pair as a combination ...

Abstract: In order to accurately predict ring gear deformations and to investigate the effects of ring gear flexibility on quasi-static behaviors of planetary gear sets, a complete load distribution model of planetary gear sets ...

Abstract: This study presents a unique experimental methodology that synchronously measures various quasi-static responses of a simple four-planet planetary gear set, namely, planet load sharing, overall transmission error (OTE), ...
