Tooth contact analysis of HGT hypoid gear drives

In machining hypoid gear with the HGT method, the large gear is machined with generated method and the pinion is machined with "tilt" method. Based on the machining principle and method of Gleason hypoid gears machined by the HGT method and on the basis of traditional machine tools with cradle mechanism, the mathematical model of machining was established and the theoretical tooth surface equations were derived; on this basis, the tooth contact analysis (TCA) including tooth contact analysis and edge contact analysis was carried out. The above steps are programmed on the computer; using numerical simulation, we can display the different parameters, gear meshing process and performance with different misalignment, verifying that the mathematical model and theoretical derivation is correct; we believe that this may serve as the foundation for Loaded Tooth Contact Analysis (LTCA).
