Abstract
In one aspect, there is provided a gear train having a sun gear, planet gear assemblies. Each planet gear assembly has a main gear meshed with the sun gear, a fore lateral gear and an aft lateral gear disposed on opposite sides of the main gear and rotating therewith. A diameter of the main gear is different than a diameter of the fore and aft lateral gears. Each planet gear assembly is rotatably mounted on a bearing for rotation about an axis. The bearing includes a journal defining two undercuts. A planet carrier rotatably supports the planet gear assemblies. Ring gears are meshed with the fore and aft lateral gears. One of the sun gear, the planet carrier, and the ring gears connected to an input, one is connected to an output, and rotation of a remaining one is limited.
