To enhance the structure strength and working life of the existing ladder-type chain connector, and chain connector productivity and manufacture craftwork. The ANSYS finite element software is utilized to simulate contact non-linear finite element analysis of ladder type chain connector. And the static and dynamic experiments are carried on several samples. Finite element simulation results show that the main part of stress concentration is in teeth roots; experiments results show that the teeth roots are the fragile parts in the chain connector, the results of finite element analysis is conformed to the results of the experiments, thus that the ANSYS finite element software is utilized to simulate contact non-linear finite element analysis of chain connector is reasonable. Because of the shortcoming of straight tooth chain connector, then promoted a chain connector of cambered surface tooth structure. Through the analysis, it shows that cambered surface can augment the contact areas in teeth, and prevent partial loading in teeth meshing. When chain connector manufactured, clamping tongs are quite complex, but the petal-type clamps structures are adopted, that can carry out volume-producing, thereby, and the productivity and processing precision are improved.
