CONDITION MONITORING METHOD

A method for monitoring a condition of a mechanical system having an oil lubricated component. The method includes: (a) identifying a start of a load cycle, (b) measuring a load of the oil lubricated component, (c) measuring a temperature of a lubricating oil for the oil lubricated component, (d) ca...

Zusammenfassung:	A method for monitoring a condition of a mechanical system having an oil lubricated component. The method includes: (a) identifying a start of a load cycle, (b) measuring a load of the oil lubricated component, (c) measuring a temperature of a lubricating oil for the oil lubricated component, (d) calculating a first system performance parameter value for a load cycle, (e) repeating steps (a) to (d) for a plurality of load cycles, and (f) comparing a plurality of first system performance parameter values calculated to identify a change in the first system performance parameter values over the plurality of load cycles. The first system performance parameter value for the load cycle is selected from a friction coefficient for the oil lubricated component, a temperature increase coefficient for the lubricating oil for the oil lubricated component, and a temperature rise rate coefficient for the lubricating oil for the oil lubricated component.
