Gear bending fatigue life is a primary consideration in gear design. Each gear tooth is
subjected to cyclic root stresses that may cause fatigue fracture. A gear in a transmission is …

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 …

In this study, an experimental methodology is presented to separate various components of
the power loss of a gearbox. The methodology relies on two separate measurements. One is …

Tooth bending fatigue failure is a primary design concern for gear designers in power
transmission applications. Fracture of a gear tooth in operation results in overload conditions to …

High-cycle gear tooth bending fatigue lives of spur gears under fully reversed and fully
released loading conditions are compared in this experimental study. The experimental …

The power loss of bearings is a significant factor in the overall efficiency in a drive unit system.
Such bearings are subject to combined radial and axial loading needed to support the …

Gear teeth undergo cyclic forces as they travel through the mesh zone. The resultant contact
and bending stresses produce fatigue damage, which can lead to failure through contact …

Power delivery in many industrial, automotive, and aerospace applications is subject to duty
cycles based on the needs of the equipment over each mission. These blocks of usage at …

In this study, tooth bending fatigue lives of spur gears are studied both experimentally and
theoretically. The primary focus is given to long-cycle fatigue performance of gears loaded …

Power losses of load carrying gear and bearing components of automotive transmissions
have become a major research area in recent years. Measurement of power loss of a gearbox …
