Abstract

The present invention defines a method of re-lubricating a grease-lubricated bearing arrangement that operates under varying conditions. The method comprises steps of determining a re-lubrication interval t* for the bearing arrangement and initiating a re-lubrication event, based on the determined re-lubrication interval t*. According to the invention, the step of determining comprises: a) measuring an operating condition C (i) of the bearing at a series of time intervals; b) recording an amount of time ”t (i) spent in each operating condition C (i) in the series; c) using each operating condition C (i) in the series as an input to a grease life model, to estimate a lubrication interval t lub (i) or a reliability value R (i) associated with each operating condition C (i) ; d) using each estimated re-lubrication interval t lub (i) or reliability value R (i) in the series and the associated amount of time ”t (i) to determine a value for t* that is based on the history of the measured conditions obtained since a reference time to that is either zero or is the time at which a previous re-lubrication event occurred.
