摘要
针对航空活塞发动机凸轮轴修理,分析了轮廓磨削对型线、接触应力、润滑特性以及耐磨性的影响,论证了修理的可行性。分析了凸轮轴修理的关键技术,提出了轮廓型线反求的测量方法和型线重构的理论模型,为凸轮轴的修理提供了理论指导。
According to the repair for camshaft of the aviation piston engine, the influences of grinding camshaft on the profile line, the contact stress, the lubrication characteristics and the wear resistance are analyzed in this paper, and the feasibility of repair is then demonstrated.The key technology of camshaft repair is analyzed, while method of reverse measurement for the profile line and theoretical model of the profile line reconstruction are then presented, thus the theoretical instruction for the re-pair of camshaft is finally provided.
