为了检验准双曲面齿轮的加工设计参数,研究采用三维几何仿真方法模拟理想齿轮的啮合过程。在切削过程建模的基础上,给出啮齿过程的接触点仿真算法,并生成齿面接触轨迹和几何接触区。结合实例,将仿真结果与理论结果、格里森软件的计算结果进行对比,证明仿真方法的有效性。系统以Solidworks软件平台进行二次开发,建立了加工设计与齿轮整体分析之间的联系,为齿轮参数优化提供参考。 In order to test the processing design parameters of hypoid gears, a three-dimensional geometric simulation method was used to simulate the meshing process of ideal gears. Based on the modeling of the cutting process, the contact point simulation algorithm of the rodent process is given, and the contact surface and the geometric contact area of ​​the tooth surface are generated. Combining the examples, the simulation results are compared with the theoretical results and the calculation results of Gleason software to prove the effectiveness of the simulation method. The system is re-developed by Solidworks software platform, and the relationship between machining design and gear overall analysis is established to provide reference for gear parameter optimization.
