© 2022, The Author(s), under exclusive licence to Springer Nature Switzerland AG.With the development of nanotechnology, the use of nanoparticles added lubrication systems has increased, and the application areas of modern tribology have expanded. In this study, the effects of nanoparticles on gearbox performance were investigated. For this purpose, sunflower oil was chosen as the base oil, and molybdenum disulfide (MoS 2), titanium dioxide (TiO 2) and calcium fluoride (CaF 2) nanoparticles were added to the base oil in certain proportions. The effects of nano additives on the efficiency and power loss of the gearbox under different operating speeds and loads have been comparatively investigated. The experiments were carried out using a gearbox test system and the measurements were obtained.
