Abstract
A gas turbine engine includes a core engine coupled to an input shaft, a fan coupled to an output shaft, and a gearbox assembly. The gearbox assembly includes a split sun gear coupled to the input shaft, a plurality of planet gears intermeshing with the split sun gear, and a ring gear intermeshing with the planet gears. The split sun gear includes a forward sun gear and an aft sun gear each coupled to the input shaft. Each planet gear includes a pin with an outer surface, a rim with an inner surface, and a clearance between the pin's outer surface and the rim's outer surface. The clearance is greater than zero when radial, pinch, tangential, and centrifugal component forces are applied to the planet gear. Each planet gear includes a pin clearance parameter greater than or equal to zero rpm and less than or equal to 3,334 rpm.
