Abstract
The present invention relates to a system for coupling an accessory box (16) of the engine (14) of an aircraft to an accessory box (12) of the aircraft, the engine accessory box being connected to a first shaft (20) inside which is slidably mounted a slide (28) carrying first coupling means (28d) capable of cooperating with second coupling means (38) carried by a second shaft (22) connected to the aircraft accessory box (12) so as to couple the first (20) and the second (22) rotating shaft, wherein it further comprises electrical means for moving the slide (28) along the axis (30) of the first shaft (20) between a first uncoupling position with the second shaft and a second first coupling position with the second shaft.
Claims17
The system for coupling an accessory box of an aircraft engine to an accessory box of the aircraft, comprising a first shaft configured to be connected to the engine accessory box and inside which is slidably mounted a slide element carrying first coupling means capable of cooperating with second coupling means carried by a second shaft configured to be connected to the aircraft accessory box in order to couple the first and the second rotating shaft, wherein it further comprises a controller configured to move the slide element along the axis of the first shaft between a first position in which the first coupling means are not coupled to the second coupling means and a second position in which the first coupling means are coupled to the second coupling means, the first shaft comprising a cylindrical bearing centred in an inner cylindrical surface of the second shaft and the slide element comprising a first cylindrical portion mounted in the first shaft, rotatably coupled thereto and connected to a second cylindrical portion centered in a cylindrical surface of the second shaft.
