A study on the improvement of meshing characteristics of a complementary curvilinear gear set generated by complementary rack cutters

This article focuses on improving the meshing characteristics of a complementary curvilinear gear set generated by complementary rack cutters. Firstly, the mathematical model of a complementary curvilinear gear set was developed based on the theory of gearing. Tooth contact analysis (TCA) was conducted to explore the influences of assembly errors on the transmission error (TE) and contact pattern. A stable point contact was successfully introduced to replace the original line contact in the improved complementary curvilinear gear set, resulting in less sensitivity to assembly errors. Finally, finite element analysis (FEA) was also utilized to calculate contact stress of the original and improved complementary curvilinear gear set.
