For the driving shaft encountering the roller and retainer breaking off and inner spacers wearing out during the engine tests, the structure analyses, vibration calculation, component measurement, quality assessment and related tests were carried out. Finally the factors effecting the driving shaft operation and the reasons of failure were defined. Several measures including shaft diameter optimization, increasing oil supply, improving manufacture quality and installation form were taken to clear up the failures. After im?provement, the testing results showed that the driving shaft worked steadily and the effect was good. At last, the key technology of radial driving shaft with three supporting points is summarized, which has a great help for the driving shaft design.
