Today they are urgently required to have high power density, efficiency, reliability, long life, low-noise, high-precision, and proper stiffness that impose great challenges to engineers and researchers. Based on the available research results achieved by the present team, involving innovative design theories of high-performance precise transmissions with a number of inventive patents, this interdisciplinary project is proposed to conduct advanced studies for the purpose of revolutionizing engineering analysis and design theories and methods, as well as manufacturing techniques, by employing cutting-edge technologies in gear engagement theory, interfacial mechanics, tribology, surface engineering, materials science, system dynamics, and reliability theory. The objectives include investigating the performing behaviors of spiral bevel and hypoid gears for special applications under extreme conditions, and revealing correlations and mutual dependence among different design and performance parameters such as those of geometric accuracy, thermal balance, failure mechanisms, reliability and durability, system dynamics and transmission errors, etc. It is expected that innovative results will be obtained to update the current theories and practices for spiral bevel and hypoid gear transimissions. Major breakthroughs and innovation are expected in the fundamental researches of the application of high-performance gears, so that crucial scientific foundations can be laid for the further improvement of China’s equipment manufacturing industry.
