Definition
Machine condition monitoring is the general topic of health monitoring of machines, which includes fault detection and diagnosis as well as fault progress tracking.
Lubricant monitoring is also commonly known as oil analysis, as it most generally involves the analysis of lubricating oil. Analysis of grease is also performed on grease-lubricated bearings and gearboxes.
Wear debris analysis involves the inspection of wear particles contained in a sample of lubricant from the gearbox (oil or grease).
Scientific Fundamentals
Gearboxes used in industry commonly feature enclosed gears to reduce foreign particle contamination and wear, and are oil lubricated. Faults developing inside these types of gearboxes can generally be diagnosed using several methods. The effectiveness of fault detection and diagnosis of each method depends on the defect and the cause of the defect. The monitoring methods typically used for gearboxes are lubricant monitoring, wear debris monitoring, and...
