Abstract: The selection of T-groove end face seals (T-EFS) with optimized structural parameters, based on operating conditions, is critical to regulating gas flow into the bearing chamber in aero-engine accessory gearboxes. Therefore, ...

Abstract: In this paper, the influence of tooth surface wear on dynamic characteristics of the gear-bearing system is discussed. The gear-bearing system considering the factors of tooth surface friction, time-varying meshing stiffness, ...
