Dynamic Characteristics Of Frictional Vibration Of Rolling Bearings

Vibration and noise performance has been is bearing of important quality and performance index. half more century yilai, people on bearing of inherent structure vibration and process errors corrugated degrees incentive of vibration for has compared in-depth of research, results on engineering practice up to has active of guide role, through reduced bearing parts work surface of process errors, bearing of vibration noise level to obviously reduced. but, gradually found, manufacturing precision of further upgrade, And there were no expected bearing vibration and noise level reduced effect, in some cases, even opposite, life and abnormal sound of noise problems are more prominent. classical bearing structure dynamics and vibration theory of emerging process error.
