Increased capacity face gear arrangement for transmitting torque through an angle and to a plurality of power extraction paths

A gear arrangement for transmitting torque from an output shaft of an engine comprising:

• a pinion shaft for receiving torque from the output shaft;
• a pinion mounted concentrically to a first end of the pinion shaft;
• upper and lower concentric and opposed face gears meshingly engaged with said pinion;
• means for permitting the pinion to float such that torque from the pinion shaft is split equally between the face gears;
• a primary driven shaft coupled to one of said face gears;
• at least one non-floating shaft having a gear in meshing engagement with said first and second face gears;
• and
• an auxiliary device operatively connected to and powered by said non-floating shaft.

A gear arrangement for transmitting torque from an output shaft of an engine comprising:

• a pinion shaft having a first end and a second end, the first end receiving torque from the output shaft;
• a spur gear mounted concentrically to the second end of the pinion shaft;
• upper and lower concentric and opposed face gears meshingly engaged with said spur gear, the second end of the pinion shaft being otherwise unrestrained;
• means for permitting the spur gear to float radially and axially such that torque from the pinion shaft is split equally between the face gears;
• a primary driven shaft coupled to one of said face gears;
• and
• at least one non-floating shaft having a spur gear in meshing engagement with said first and second face gears.
