148216 - Intelligence Optimization Model of Spiral Bevel Gear Based on Design-Manufacturing Collaboration 

Spiral bevel gear pairs with high power density should consider the characteristics of high strength, high efficiency, high precision, stability, low noise, light weight, etc. The large number of geometric variables, the lengthy and cumbersome design optimization process, as well as the costly mesh performance test that is easily influenced by external factors such as manufacturing error, etc., all limit the potential exploitation of bevel gears. As a result of the design-optimization-test verification process, a closed-loop intelligence optimization model for high-power density spiral bevel gears based on design-manufacturing collaboration was developed. Firstly, based on the design principle of root line tilt and strength evaluation criteria, the genetic algorithm nonlinear optimization technology was used to optimize the macro-geometric design variables with the purpose of minimizing the volume of spiral bevel gear pairs. The mapping relationship between machining parameters and tooth surface was then established, and an intelligent optimization model for the micro-morphology of spiral bevel gears was proposed using tooth surface topology modification technology. The loaded contact performance of spiral bevel gear was precisely quantified utilizing the global flexibility and Hertz contact models, with meshing compatibility and equilibrium conditions synthesized. Based on specific design examples, the proposed intelligent optimization methodology was used to precisely configure high-power density bevel gears with the purpose of optimizing loaded contact performance. Finally, the designed gear pair's performance was tested and validated utilizing numerical assembly and loaded contact analysis techniques. The proposed intelligence optimization model of spiral bevel gear, which is based on design- manufacturing collaboration, contributes to the design theory of high-power density gear transmission.
