The invention relates to a driving device of a high-pressure shaft of an engine and a driving method thereof. The driving device of the high-pressure shaft of the engine comprises a manual lever, wherein a head structure is arranged at the end part of the manual lever; the gear shaft covering cap comprises a fixed part, a movable part and a locking device, a cavity for containing the movable part is formed in the top of the fixed part, and the fixed part and the movable part are in a mutually locked or unlocked state through the locking device. Wherein a lock hole is formed in the top of the movable part, the head structure of the manual rod can be inserted, matched and fixed with the lock hole, so that the locking device is switched between a locking state and an unlocking state, in the unlocking state, the movable part can move in the length direction of the cavity, and the bottom of the movable part can be matched and fixed with a gear shaft of the engine. The invention provides a driving device of an engine high-pressure shaft and a driving method of the driving device. The problem that a manual lever gear shaft covering cap is neglected to be installed in the maintenance process of an aero-engine can be avoided.
Description
technical field [0001] The invention relates to the technical field of design and manufacture of aero-engines, in particular to a drive device for an engine high-pressure shaft and a drive method thereof. Background technique [0002] During the maintenance of the aero-engine, a manual lever is required to rotate the high-pressure shaft of the engine during hole detection. At this time, the manual lever cover on the accessory gearbox needs to be opened, and the manual lever is inserted into the manual lever gear shaft in the accessory gearbox. Rotate the gear shaft in the accessory gearbox to drive the high-pressure shaft of the engine to rotate, so as to achieve the purpose of the borehole probe to observe all the blades. [0003] However, due to the influence of human factors, line maintenance personnel sometimes forget to install the manual lever gear shaft port cover back to its original position after completing the work. If the engine continues to run, there will be a...
