Abstract
Abstract A gear arrangement for transmitting torque through an angle and through a plurality of power extraction paths. The arrangement includes a driving shaft, a floating spur gear pinion concentrically mounted on the drive shaft, a pair of concentric and opposed face gears that are in meshing engagement with the pinion, a primary driven shaft mounted to one of the face gears and at least one non-floating spur gear also in meshing engagement with both face gears. The driving shaft is located by a bearing or a flexible coupling at the shaft end remote from the gear box to allow the pinion to float freely. Useful power may be extracted from both face gears and the non-floating spur gear as well as additional spur gears that are placed in meshing engagement with the face gears.
