| Summary: | Based on the analysis of the generating mechanism for cylindrical gears with curvilinear shape teeth,a new way of such gear modeling for manufacture is proposed.Adopting the secondary development of UG and the approach of gear blank rolling feed and gear cutting tool rotary,the three-dimensional model of such gears is accordingly built.And the contact stress calculation formula of the curve of the cylindrical gear is established based on the HERTZ formula.Then,with the analysis of the model strength and finite elements performed,it’s confirmed that the contact strength of tooth surface of cylindrical gear with curvilinear shape teeth could be substantially improved,compared with that of spur gears,and that the maximal stress equivalent is 73.8% of spur gear and 76.57% of helical gears.Therefore,the theoretical basis and guidelines for industrial applications of cylindrical gears with curvilinear shape teeth are provided by this approach. |
