Decreasing the friction loss of gears has recently become one of the most important problems, because this relates to saving energy. This problem has been studied, but they have not yet been made clear. In this study, we carried out, using a power circulating test equipment, the experiments to examine the influence of the center distance and the gear ratio concerning with the friction loss of spur gears. The center distance of gears used in tests were a = 48, 91.5 and 183 mm and the gear ratio were i = 1〜2.8. Test results showed that the longer the center distance, the lower the friction loss and the friction loss of gear ratio i = 1 was the lowest compared with other gear ratio. We found the relationships between the product of the mean coefficient of friction μ_m and the relative curvature radius at pitch point ρ mm and the mean sliding velocity Vgm m/s.
