Vibration Transmission Characteristics of Bearings Related to Machinery Condition Monitoring

摘要

Signal transmission through non-linear elements such as oil films and clearances is investigated for bearings of types commonly used in rotating machinery. Rolling element bearing response is found to be strongly dependent on load, and machines using this type of bearing will have non-linear transfer characteristics. Oil film journal bearing response is less susceptible to operating conditions and this type of machine element should not significantly affect the transmission of condition monitoring signals.
