Abstract
A split planetary gear assembly having a pair of helical gearsets. The first helical gearset includes a first sun gear, a first ring gear, and a set of first planet gears meshed with the first sun gear and the first ring gear. The second helical gearset includes a second sun gear, a second ring gear, and a set of second planet gears meshed with the second sun gear and the second ring gear. The components of the second helical gearset have the same number of teeth, helix angle, and tooth pitch as the components of the first helical gearset with the exceptions that their angular helix orientation (i.e., left-hand/right-hand) is reversed and they are circumferentially indexed by one-half tooth pitch. In addition, the first and second planet gears are arranged in paired sets and supported on a common pinion shaft which, in turn, is fixed to a planet carrier. The second sun gear is splined for rotation with and limited axial movement relative to the first sun gear.
