Gear fundamental data refer to the key material, structure, performance, and other indicator parameters in the process of design,manufacturing, operation, and maintenance, which is a key factor in the active design of high-performance gear transmission and isthe part where the current gap in technology accumulation between domestic and foreign gears is the most significant. In response tothe requirements of high-performance equipment with high reliability and long service life under extreme service conditions, thesurface integrity of high-performance gears, anti-fatigue design, and manufacturing of transmission systems for domestic materialsand process environments were investigated. A small-sample gear fatigue test method based on ensemble learning and dataaugmentation was proposed and significantly reduced the test time and sample requirements. More than 10,000 fundamental data,such as fatigue S-N curves, strength limits, scuffing limits, and surface integrity parameters for 16Cr3NiWMOVNbE, 9310,18CrNiMo7-6, 42CrMo, and 20Cr2Ni4A materials were established, and a comprehensive high-performance gear database softwareincluding more than 500 parameters, such as materials, processes, structures, and performance, was developed, significantlyimproving the efficiency of gear data fundamental management. A temperature-stress-vibration signal wireless acquisition device wasdeveloped. The manufacturing processes for high surface integrity, such as carburizing and grinding, shot peening, fine particlepeening, barrel finishing, ion implantation, and thermal barrier coating, were explored. As a result, the contact fatigue/bendingfatigue/scuffing limits of the gears were significantly improved compared with those of the International Organization ofStandardization standards, which effectively promoted the innovation of lightweight transmissions for gears and provided technicalreserves for next-generation advanced equipment.
