The invention relates to the technical field of aircraft maintenance, in particular to a method for repairing gear tooth surface abrasion, in particular to a method for repairing gear tooth surface abrasion of a helicopter reducer. The method sequentially comprises the steps of judging the tooth surface state, determining the abrasion range, coping the working surface of the gear, carrying out acid etching inspection on the gear, carrying out stress relief treatment on the coped gear, carrying out shot blasting treatment on the coped tooth surface, carrying out vibration polishing on the toothsurface, and inspecting. By adopting the method provided by the invention, the motion stability of the repaired gear and the uniformity of load distribution can be ensured, the bending fatigue strength of the gear teeth is increased, and the bearing capacity of the gear teeth can be improved. Cracks in the tooth surface layer are prevented from expanding, so that peeling and pitting corrosion ofthe tooth surface are reduced, and the service life of the gear is prolonged.
本发明涉及飞机维护技术领域,具体涉及一种齿轮齿面磨损的修理方法,尤其是一种直升机减速器齿轮齿面磨损的修理方法。该方法工序依次为:判断齿面状态、确定磨损范围、对齿轮工作面修磨、对齿轮进行酸蚀检查、对修磨后齿轮进行消除应力处理、对修磨后的齿面进行喷丸处理、对齿面进行振动光饰、检验。采用本发明提出的方法,可保证修复后齿轮运动的平稳性及载荷分布的均匀性,增加了轮齿的弯曲疲劳强度,可提高其承载能力。阻止齿面表层内的裂纹扩展,以减少齿面的剥落和点蚀,提高齿轮的使用寿命。
