Abstract: Gear bending fatigue performance is the key design index of modern gear transmission, which affects the service performance and reliability of advanced gear equipment. Although significant progress has been made in the research of gear bending fatigue, the performance of high-performance gear transmission products in China is limited due to the gap between the basic data construction, anti-fatigue manufacturing and active design methods and the advanced level of foreign countries. The research progress and development trend of gear bending fatigue are described in detail based on literature research, industry communication and research experience. The research progress and development trend of gear bending fatigue are described in detail based on literature review, industry communication and project research experience. The failure mechanism, theoretical analysis, test technology, load capacity and influencing factors of gear bending fatigue are mainly introduced. The effective measures to improve the bending fatigue performance of gears are summarized, which is expected to promote the development and application of gear anti-fatigue technology in China.

Key words: gear bending fatigue, fatigue limit, S-N curve, surface integrity
