Bearing preload and gearbox power loss across the speed rangeBearing preload is a small mechanical setting with a large influence on gearbox behavior. In a geared aircraft engine, it changes the contact forces inside…
How Oil Jet Location Shapes Losses in High-Speed Planetary GearsIn a geared aircraft engine, the oil jet has several jobs at once. It must deliver enough lubricant to the gear mesh and bearings, remove heat, support surface…
A design-of-experiments approach to spline fit selection for spline fretting fatigueSpline couplings transfer torque while accommodating assembly, thermal, and geometric movement between connected components. In an aircraft engine gearbox,…
Robust Gear Microgeometry For Misaligned AssembliesTransmission error is a central concern in high-speed geared aircraft engines. It represents the deviation between the actual and ideal motion transmitted…
Bearing Cage Pocket Clearance, Skew, and Thermal BehaviorIn a rolling-element bearing, the cage is often treated as a simple separator between balls or rollers. In high-speed aerospace gearboxes, however, its pockets…
Balancing Gearbox Weight and Stiffness with Response SurfacesA geared aircraft engine can gain propulsive efficiency by allowing the turbine and propeller to operate at different speeds. That advantage depends on a…
The Effect of Planet Gear Pin Misalignment on Bearing Load and LifePlanetary gearboxes achieve high torque density by distributing power through several planet gears. That distribution depends on the planets sharing load as…
Optimizing Gear Tooth Surface Finish Through Grinding And SuperfinishingIn a geared aircraft engine, tooth surface quality has a direct relationship with efficiency, durability, acoustic behavior, and power density. The final…
