摘要

An accessory gearbox assembly (28) of a gas turbine engine (10) comprises an accessory gearbox (54) and a plurality of accessories (56) arranged to be driven by the accessory gearbox (54). The accessory gearbox (54) comprises a gear train and an accessory gearbox casing (58) enclosing the gears of the gear train. Each accessory (56) is driven by a drive shaft (57) and the drive shafts (57) of the accessories (56) may be parallel. Each accessory (56) has a first end and a second opposite end. Each accessory (56) is secured at the first end to the accessory gearbox casing (58), a plurality of accessories (56) are secured to a first side (58A) of the accessory gearbox casing (58) and the second opposite end of at least two of the plurality of accessories (56) are secured to a structural cross member (62). The structural cross member (62) increases the stiffness and strength of the accessory gearbox assembly (28) and allows the accessory gearbox casing (58) to be reduced in thickness and reduces weight and cost.
