Abstract: The present technique, in accordance with certain embodiments, provides a novel gearing assembly. The exemplary assembly includes a planetary or epicyclic gear set that provides the final gear reductions from the output shaft. Specifically, the use of a planetary gear set for final reduction transfers rotation and torque to four planet gears, for instance, which drive a carrier assemblies that, in turn, causes rotation of the output shaft. Advantageously, such an assembly can provide high torque-levels (e.g., 300,000 inch-pounds) via a relatively small-sized device.

Abstract: A power system. The system comprises a gearbox. The system may also comprise a motor. The gearbox comprises a gearbox input shaft and a gearbox output shaft. The gearbox output shaft is oriented transverse to the gearbox input shaft. The motor has a motor output shaft. The gearbox has a motor mounting portion to enable the motor to be secured to the gearbox transverse to the gearbox.
