Embodiment Construction

[0011] Below in conjunction with accompanying drawing the present invention is described in further detail, please refer to Figure 1 to Figure 2 .

[0012] A transmission mechanism of an aircraft flap control system, comprising a power source 1, a flexible shaft 4 connected to the power source 1, a drive mechanism 7 connected to the flexible shaft 4, the flexible shaft 4 is used as a power transmission mechanism, along the span of the wing The bending connects the power source 1 with the drive mechanism 7 . As a mechanism for power transmission, the flexible shaft 4 can be bent along the span of the wing to connect the power source 1 with the drive mechanism 7 to transmit high-speed, low-torque power. When the power source 1 moves, it drives the drive mechanism 7 on the other side of the flexible shaft 4 to move.

[0013] The flexible shaft 4 includes a flexible shaft core 9, a protective sleeve 10, a connecting nut 8, a left connecting copper sleeve 2, and a right connecti...

Abstract

The invention belongs to the field of aircraft design, and in particular relates to an aircraft wing flap operating system drive mechanism. The aircraft wing flap operating system drive mechanism comprises a power source, a flexible shaft and a drive mechanism, wherein the flexible shaft is connected with the power source; the drive mechanism is connected with the flexible shaft; as a mechanism for transmitting power, the flexible shaft bends along aircraft wing flaps, and connects the power source and the drive mechanism. According to the invention, the flexible shaft is used for replacing a torque tube as a drive mechanism, can transmit high rotation speed and low torque in a smaller space, and does not need a large motion space; because the flexible shaft can surround other parts with certain bending angle, does not need to steer using a universal joint, and reduces parts; a clearance is preserved at the butt joint part of the flexible shaft and the drive mechanism, and the size of the clearance can be determined according to the aircraft wing flap deformation degree, and is about 6mm; the connection mode of the preserved clearance can eliminate errors probably caused by temperature variation, structure deformation or manufacturing and processing.
