A Unified Theory on Tooth Geometry and Applications of Hypoid Gear

Higher efficiency and lower noise and vibration performance are both required for automobile gear systems. A new tooth design theory, which can be applied to all kinds of gears, was established by the integration of geometry and dynamics. This theory can create the optimal tooth shape automatically to satisfy the target dynamics performance by using a tooth contact path optimization method which solves the inverse problem of three-dimensional tooth geometry and dynamics. A new hypoid gear system is developed to realize both a bearing with no dynamic load and the higher robustness of error-free assembly.
