On the Free Vibration of High-Speed Ball Bearing Retainer

  • As a basic component of mainshaft ball bearing in aero-engine, retainer vibration plays an important role in the strength and stability of the retainer and the bearing performance. With finite element method, the free vibration performance of the retainer is examined. The results show that: 1)Apart from rigid-body motion, there is no natural frequency less than 751.12 Hz for the examined retainer. 2)With the retainer vibrating like a ring as a whole, it has some local vibration modes of side and across beams. 3)The rotation of the retainer makes its natural frequency, front-and back-moving vibration frequencies unequal with each other, which makes its resonance being excited easier.
