Abstract

The invention discloses a built-in engine side-mounted joint assembly and belongs to the technical field of engine installation. The built-in engine side-mounted joint assembly comprises a joint body,an upper joint, a lower joint, a shaft pin, an inner locking bolt, a locking flange and a locking device; wherein the joint body is mounted on an engine body; the upper joint is fixed to the joint body and has one end hinged to the lower joint; the middle parts of the upper joint and the lower joint are provided with arc slots; the upper joint and the lower joint are connected to form an openinginstalled in cooperation with the shaft pin; the shaft pin is connected to a main engine mounting joint through the joint body; the axial installation of the shaft pin is adjusted by the locking flange; the inner locking bolt passes through the shaft pin to be installed in cooperation with the threaded hole of the main engine mounting joint; and after the free end of the lower joint is rotated tobe connected with the upper joint, the free end of the lower joint is fixed by the locking device. The built-in engine side-mounted joint assembly, by the cooperation of the shaft pin, the inner locking bolt and the locking flange, ensure the bearing capacity of the side-mounted joint and the simple and quick assembly.

Description

technical field [0001] The invention belongs to the technical field of engine installation, and in particular relates to a built-in engine side-mounted joint assembly. Background technique [0002] At present, the most common large and medium-sized aircraft at home and abroad generally adopt the form of engine wing suspension, the technology is relatively mature, the engine installation space is open, and the construction is convenient. However, when the installation space of the engine is small, the space is not open, and the construction is difficult, the installation of the wing-mounted engine is difficult and it is difficult to ensure the assembly accuracy. Contents of the invention [0003] Purpose of the present invention: In order to solve the above problems, the present invention proposes a built-in engine side-mounted joint assembly, which adopts the technical scheme of combining the shaft pin and the shaft-holding joint, so as to solve the problem of small instal...
