Study on Planetary Gear Drive Using Internal Gear Easily Ground
Journal of the Japan Society for Precision Engineering Contributed Papers, 2004 A planetary gear drive having the internal gear that can be easily ground is developed. This gear drive is composed of the three parts; the internal gear finished by the grinding wheel with a trapezoid profile, the planet gear conjugate to the internal gear, and the sun gear conjugate to the planet gear. In this paper, a method to design the gear tooth

Landing Impact Load Analysis and Validation of a Civil Aircraft Nose Landing Gear
Aerospace, 2023 Landing impact load design is essential, but the process has rarely been fully described, and some designers have even neglected the differences between wheel-axle and ground-contact loads, as well as loads in the longitudinal direction, especially in ...

Evaluation of Carburized and Ground Face Gears [PDF]
Journal of the American Helicopter Society, 2000 Experimental durability tests were performed on carburized and ground AIS19310 steel face gears. The tests were in support of a Defense Advanced Research Projects Agency (DARPA) Technology Reinvestment Program (TRP) to enhance face-gear technology. The tests were conducted in the NASA Glenn spiral-bevel-gear/face-gear test facility.
