Experimental study on gearbox oil blended with composite additives

Friction and wear in moving kinematic links is a crucial cause for energy drop in a gearbox system. It can be governed by consuming modified lubricants or investigating the influence of additives on existing oil. The tribological performance of wind turbine Gearbox has unfavorably influenced by aspects such as nature of loading, type of oil and speed, etc. This paper presents an experimental investigation on oil mixed with Al2O3/ZrO2/SiO2 Nanocomposites in combination with Zinc DialkylDithio Phosphate for various conditions. The process variable levels for the four-ball tribometer are designed for concentration in the percentage of weight as 0.005, 0.01, and 0.02. Experimentation on a Fourball tester is performed to determine wear scar dia. and friction coefficient. It is observed that the addition of composite additives in combination with ZDDP reduces COF and wear scar diameter by 1.4 % and 13.4 % individually.
