Beschreibung
Zusammenfassung:	The invention belongs to the technical field of aero-engines, and particularly relates to an aero-engine accessory casing which comprises a plurality of gear shafts, the gear shafts are erected in the accessory casing through bearings, gears are arranged on the gear shafts, and the gears on the adjacent gear shafts are meshed with each other; the gear shaft is divided into a first gear shaft, a second gear shaft and a third gear shaft through the bearing load of the bearing; the bearing load of the bearing of the first gear shaft is smaller than a first preset value, the bearing load of the bearing of the second gear shaft is larger than or equal to the first preset value and smaller than or equal to a second preset value, and the bearing load of the bearing of the third gear shaft is larger than the second preset value. Bearings of the first gear shaft are ball bearings; one end of the bearing of the second gear shaft adopts a ball bearing, the other end of the bearing adopts a rod bearing, the distance betw
