ACCESSORY GEARBOX ASSEMBLY AND METHOD FOR PROVIDING ROTATIONAL ENERGY TO ACCESSORY COMPONENT IN ACCESSORY GEARBOX

摘要

PROBLEM TO BE SOLVED: To provide an improved accessory gearbox assembly.SOLUTION: The accessory gearbox 10 for an aircraft is connected to an engine core 12 via a power transfer shaft 14 to provide rotational energy to an accessory component 22 located at a longitudinal end 24 of the gearbox 10. Gears 16 are contained in a gearbox housing 18 and are disposed at least partially within an accessory housing 30. Spur gear teeth 34 meshes with gear teeth 36 to rotate around a spur axis 32. Spur gear 28 rotates an accessory shaft 38 to transfer power to the accessory component 22. Connection of the accessory component 22 to the gearbox 10 via the spur gear 28 allows for simple adjustment of the rotational speed of the spur gear 28 and the rotational energy provided to the accessory component 22 by changing the number of spur gear teeth 34 or gear teeth 36.
