The invention provides a helicopter speed reducer case broken hole war injury first-aid repair method. The method comprises the following steps that firstly, a damaged part is filed; 2, impurity removal of a speed reducer; thirdly, the broken holes in the inner side are blocked, the strength of the broken holes is enhanced, the broken holes of the speed reducer are covered with a metal net, and a blocking pad capable of blocking the broken holes in the inner side and not blocking the side walls of the broken holes is arranged on the metal net; fourthly, the broken holes are repaired, and the broken holes are bonded through an adhesive; and fifthly, the adhesive is cured, and the protruding adhesive is polished after curing is completed. The repairing adhesive can be used for repairing a large broken hole, most strength of a damaged part can be recovered, the contact area between the adhesive and the side wall of the broken hole of the cartridge receiver is large, the compression resistance and tensile load resistance are high, lubricating oil leakage caused by cracking of a to-be-bonded part in the using process can be effectively avoided, the usable time after repairing is long, and the repairing effect is good. The method can be used in a high-stress area of a reducer casing to ensure the flight safety of a helicopter.

    本发明提供一种直升机减速器机匣破孔战伤抢修方法,包括如下步骤:步骤一、损伤部位锉修;步骤二、减速器除杂;步骤三、阻挡内侧破孔,加固破孔强度,使用金属网覆盖减速器的破孔,在金属网上设置能够挡住内侧破孔且不挡住破孔侧壁的挡垫;步骤四、修补破孔,使用胶粘剂粘接破孔;步骤五、固化胶粘剂,待固化完成后打磨突出的胶粘剂。本发明可以用于较大破孔的抢修,能够恢复损伤部位的大部分强度,并且胶粘剂与机匣破孔侧壁接触面积大,抗压和抗拉伸载荷能力大,并且可有效避免使用过程中应粘接部位裂开导致的润滑油泄漏,抢修后可使用的时间较长,可用于减速器机匣高应力区域,保证直升机的飞行安全。
