Experimental Analysis of Chemically Degraded Lubricant’s Impact on Spur Gear Wear

The impact of lubricating oil degradation, which can happen during both storage and use, on spur gear wear is thoroughly examined in this paper at all scales, from macro to nano. A thorough structure was created by combining the results testing performed macroscale a test rig nanoscale using tools such as FESEM analysis. Using single-stage transmission under two different working conditions (‘40 Nm, 1200 rpm, 198 h’ ‘50 500 90 min’), experiments were carried out conventional artificially degraded lubricant oils. Aqueous hydrochloric acid (36.46% v/v concentration) added induce artificial degradation. Wear development degradation monitored real time metallic detritus sensors sensor suites. Offline methods, total number (TAN) pH value readings, used with periodic samples. It discovered through online offline monitoring methods that experienced substantial lubricant-degraded conditions. By demonstrating elevated levels oxidative products formation new compounds, sulphates aromatic groups, attenuated reflection-Fourier transform infrared spectroscopy (ATR-FTIR) analysis verified this. In addition, water creation noted. interesting note meter has become viable option for detecting offers useful way keep track quality. Overall, study shows there strong connection between phenomena complete method assessing tribological performance lubricants.
