A flap motion limiting mechanism

Abstract

The invention relates to a mechanism for limiting the motion of a wing flap. The mechanism comprises a limit wheel support (1), a first bearing set (2), a circlip set (3) for holes, a working shaft (4), a second bearing set (5), a small shaft set (6), a stopper screw set (7), a flat head shaft set (8), a third bearing set (9) and a split pin set (10). Through the change of the value of a gap between upper and lower limit mechanisms at the connecting position of two sliding rails, and a web surface of one sliding rail, the situation that the space motion of the wing flap performs along a designed limit track is guaranteed, the motion of the wing flap in the other directions is simultaneously limited, and the situation that the wing flap cannot be stuck during the motion is guaranteed.

Description

technical field [0001] The invention belongs to the field of aircraft design and relates to a flap motion limiting mechanism. Background technique [0002] The traditional flap motion limiting mechanism can only limit the movement in a single direction during the flap retreat or deflection process, and cannot guarantee the retreat or deflection of the flap at the same time, while the new aircraft outer flap requires the flap In the process of retreating, it must be deflected outward at the same time. This movement is a relatively complex spatial movement pattern, and the general stop mechanism cannot meet this design requirement. [0003] Aircraft flaps are generally supported by two or more slide rails and move along the direction of the slide rails. If the design of each flap movement limiting mechanism is unreasonable, the flaps may be stuck during the movement process. , affecting the normal movement of the flaps. Contents of the invention [0004] The purpose of the...
