The embodiment of the invention provides a generator and an aircraft, and relates to the technical field of generators. The generator comprises a generator flexible shaft and a flexible ring, the generator flexible shaft comprises a flexible shaft body, a retaining shoulder and an external spline, the retaining shoulder is arranged on the outer wall of the flexible shaft body in a protruding mode, the external spline is arranged on the outer wall of the flexible shaft body, the external spline and the retaining shoulder are distributed at intervals, and the flexible ring is arranged on the flexible shaft body in a sleeving mode and located on the side, close to the external spline, of the retaining shoulder. When the engine and the generator are assembled, the inner spline shaft end of the engine is matched on the outer spline, the flexible ring is sleeved on the flexible shaft body, the inner spline shaft end of the engine cannot directly impact on the retaining shoulder of the generator flexible shaft, and meanwhile, the flexible ring can buffer the inner spline shaft end of the engine, so that the vibration of the generator flexible shaft is reduced, and the service life of the generator is prolonged. Meanwhile, the shoulder of the generator flexible shaft is protected, and the generator flexible shaft is prevented from being damaged.
本发明的实施例提供了一种发电机及飞行器,涉及发电机技术领域。该发电机包括发电机软轴和柔性环,发电机软轴包括软轴本体、挡肩以及外花键,软轴本体的外壁上凸设有挡肩,软轴本体的外壁上设有外花键,外花键和挡肩间隔分布,柔性环套设在软轴本体上,且位于挡肩靠近外花键的一侧,在发动机和发电机装配时,发动机的内花键轴端配合在外花键上,由于柔性环套设在软轴本体上,发动机的内花键轴端并不会直接撞击到发电机软轴的挡肩上,同时,柔性环也可以对发动机的内花键轴端进行缓冲,发电机软轴的震动减少,同时也保护了发电机软轴的挡肩,避免了发电机软轴的损坏。
