The meshing performance analysis of hypoid gear tooth surface is based on the accurately established tooth surface model, including geometric contact analysis (TCA) and loaded contact analysis (LTCA). By simulating the meshing process of paired hypoid tooth surface under no-load and load conditions, the corresponding geometric transmission error (UTE), unloaded contact pattern (UCP) Loaded te (LTE), loaded CP (LCP), tooth surface load distribution, load distribution between teeth, contact stress and bending stress change process are important means to analyze and pre control the meshing performance of gears in the design stage.
The tooth surface design of hypoid gear aims at the preset meshing performance of the tooth surface (including contact marks and transmission errors), and uses the spatial meshing principle and differential geometry to design the matched hypoid gear tooth surface that meets the preset performance requirements and calculate the corresponding processing parameters, including machine tool settings, cutter head and tool parameters.

The contents of this paper mainly include precise modeling of cycloid hypoid gear tooth surface, TCA, LTCA, edge contact analysis (etca), calculation of bending stress and contact stress process, calculation of time-varying meshing stiffness of gear pair, analysis and pre correction of tooth surface error sensitivity, active design of tooth surface, meshing simulation analysis of actual hypoid gear tooth surface, and corresponding experimental verification and comparative analysis.
