Abstract
Sliding loss and power loss are the most dominating concern to mechanical power transmission system by any type of gear. Power loss is profoundly influenced by the friction force and friction loss between two gears in contact. In this study, four types of lubricating gear oils 5W30, 10W30, 10W40 and 15W50 were tested for different properties using nylon gears test set up. Test results revealed that 5W30 oil has highest stabilization temperatures among all tested oils. On the other hand, 15W50 oil exhibited lowest stabilization temperatures. It was also observed that gear oil 10W30 has higher stabilization temperatures than gear oil 10W40. The obtained results show that friction coefficient gradually decreases with the increase in rotational speed ranging from 500 to 1000 RPM for all tested gear oils. Experimental data also show that power loss of nylon gear increases with the increase in sliding speed.
