abstract = {The rapid evolution of advanced equipment that utilizes gears, including aviation engines, helicopters, and wind turbines, imposes escalating demands for enhanced reliability, prolonged lifespan, increased power density, and sustained durability of gears. Gear contact fatigue issues, associated with materials, geometries, and operating conditions, are crucial to modern gear design. To date, enormous theoretical and experimental studies have been conducted to understand gear contact fatigue mechanisms. To compile and categorize key investigations within a broad and active research field, this work reviews recent studies of gear contact fatigue. Emphasizing theories, tests, and anti-fatigue design approaches, this work aims to provide a comprehensive overview of recent developments in this significant area of research.}
