摘要

A method for predicting the residual life of a rolling-element bearing comprising the step of: measuring the magnitude and/or the frequency of occurrence of vibrations or high frequency stress waves emitted by rolling contact of said rolling-element bearing, recording said measurement data as recorded data, and predicting the residual life of said rolling-element bearing using said recorded data and an International Organization for Standardization (ISO) 281 rolling-element bearing life model. A life modification factor is determined from in service measurements of at least one parameter indicative of lubrication cleanliness and/or film thickness rather than using said International Organization for Standardization (ISO) 281 rolling-element bearing life model's assumed or predicted lubrication cleanliness values.

1. A method for predicting a residual life of a rolling-element bearing comprising steps of:
measuring at least one of a magnitude and a frequency of an occurrence of one of vibrations or high frequency stress waves emitted by rolling contact of said rolling-element bearing, recording said measurement data as recorded data, and predicting the residual life of said rolling-element bearing using said recorded data and an International Organization for Standardization (ISO) 281 rolling-element bearing life model, whereby a life modification factor is determined from in service measurements of at least one parameter indicative of at least one of a lubrication cleanliness and a film thickness rather than using said International Organization for Standardization (ISO) 281 rolling-element bearing life model's assumed or predicted lubrication cleanliness values.
