Abstract:  A design methodology for hypoid gears in low crossed shaft angle was proposed. The geometric relationships of pitch cones  were derived based on the instantaneous axis of uniparted hyperboloid. Considering the root part smoothness， the mesh behavior controlling methodology of hypoid gears with low crossed shaft angle was proposed. The finite element analysis was performed to investigate the influences of different loads on the mesh behavior. The prototype of hypoid gears proposed may work in low crossed shaft angle stably.
