Patent ID: 8015900

Claim:
A split torque gearbox system comprising: a first spur gear mounted for rotation about a first spur gear axis of rotation; a second spur gear mounted for rotation about a second spur gear axis of rotation; and a floating pinion gear mounted to a radially unsupported pinion shaft in a cantilever manner and driven by said radially unsupported pinion shaft, said floating pinion gear mounted for rotation about a floating pinion axis of rotation which provides a resilient characteristic, said floating pinion gear meshed with said first spur gear and said second spur gear, said floating pinion gear axis of rotation displaceable to split a load between said first spur gear and said second spur gear, said floating pinion axis of rotation, said first spur gear axis of rotation, and said second spur gear axis of rotation located along a common line, said radially unsupported pinion shaft driven through a gear mesh generally transverse to the floating pinion axis of rotation such that said radially unsupported pinion shaft is displaceable off said common line to define a displacement envelope within which said floating pinion gear axis of rotation may he displaced through flexing of said radially unsupported pinion shaft to split said load between said first spur gear and said second spur gear.
