Abstract:

Oil contamination is the most common and serious source of machine failure. Therefore, lubrication oil testing and analysis is one of the most important condition monitoring (CM) techniques for machinery maintenance and failure diagnosis. Oil analysis consists of determination of physical-chemical properties, contamination and wear debris analysis (WDA). One of the modern methods how to detect wear particles is LaserNet Fines (LNF). The technology is an extension of effective laboratory microscope analysis and was developed specifically to address the shortfalls of monitors that measure only particle size or elemental concentration. Universal tractor oil (UTTO) is the multipurpose oil for the lubrication of the transmission, rear axle, differential, wet brakes, and hydraulic system fed by the common oil reservoir.

The aim of this work is detection and characterization of friction particles during lifetime of two different universal tractor transmission oils samples with using of laser particle counter LaserNet Fines-C and their comparing, synthetic ester-based UTTO oil and mineral-based UTTO oil.
