In recent years, there has been a demand for technology for achieving carbon neutrality. To meet this demand, improvements in gear transmission efficiency are being studied for vehicle on-board electrical equipment motors. And the lubricating oil and solid lubricant used in the gear will affect the transmission efficiency. In this study, we experimentally analyzed the effect of the particle size of the solid lubricant in the lubricating oil on the tribological characteristics with a pin-on-disk friction tester and PAO lubricating oil to which PTFE solid lubricant was dispersed. As a result, we obtained the following findings. The difference in the particle size of the solid lubricant dispersed to the lubricating oil affects the tribological characteristics. And as the particle size increases, the coefficient of friction tends to increase.
