Research on Virtual Hobbing Simulation and Study of Tooth Surface Accuracy of Involute Helical Gears

摘要

Based on the gear generation principle, taking the professional software as the tool, the problem of virtual hobbing simulation on involute helical gears was studied, and virtual hobbing simulation of hobbing on the whole gear was completed by using macros of CATIA V5. The validity of this method was validated through analyzing the tooth surface accuracy error of the model which was below 1μm between the virtual tooth surface and the theoretical tooth surface and the possible factors affected the tooth surface accuracy during manufacturing was also carried on the discussion. It offers a fictitious three-D platform for studying the principle of gear cutting machine's error as well as the finite element analysis between the ideal tooth surface and the erroneous tooth surface.
