【摘要】：本文从齿轮的啮合理论出发,经过推导得到了变位渐开线斜齿轮的精确齿廓曲线,对斜齿轮的生成方式进行了分析,提出了检验生成的斜齿轮精度的模型,并对斜齿轮生成方式的精度进行了检验。得出的变位斜齿轮模型真正的做到了参数化,可以对任意的合理输入生成模型。所提出的检验方法可以对目前在PRO/E中的斜齿轮造型方式进行检验,并可以给出齿轮模型的误差。以VB为平台开发,以NGW型行星齿轮传动系统设计理论为基础,完成了NGW行星传动系统的参数化设计。以Pro/E为支撑平台,以Automation Gateway为桥梁完成了VB与Pro/E之间的二次开发,将各零部件按照其装配关系集成为NGW行星传动系统,并利用VB与EXCEL的连接生成齿轮几何参数表。所生成的系统能够精确的描述NGW行星变速器,并可以方便的与设计系统相连接。通过对齿轮修形方式的比较与分析,给出了各种修形方式在PRO/E中的实现方法,并给出其修形后齿形的示意图。以NGW行星传动系统中的太阳轮为研究对象,按照现有的齿轮修形公式,变形后得到了考虑轴安装平行度误差的修形量计算公式。并根据齿面接触应力随修形量的变化趋势,通过ANSYS中的Workbench模块对计算模型进行接触应力分析,验证了该修形量计算公式的合理性。
[Abstract]:Based on the meshing theory of gear, the accurate profile curve of modified involute helical gear is derived in this paper. The generating mode of helical gear is analyzed, and a model to test the accuracy of the generated helical gear is put forward. The accuracy of helical gear generation is tested. The modified helical gear model is parameterized and can generate any reasonable input model. The proposed method can be used to test the modeling method of helical gear in PRO/E, and the error of gear model can be given. Based on the design theory of NGW type planetary gear transmission system, the parametric design of NGW planetary transmission system is completed on the platform of VB. The secondary development between VB and Pro/E is completed by using Pro/E as the supporting platform and Automation Gateway as the bridge. The components are integrated into the NGW planetary transmission system according to their assembly relationship, and the gear geometric parameter table is generated by the connection of VB and EXCEL. The generated system can accurately describe the NGW planetary transmission and can be easily connected to the design system. Through the comparison and analysis of gear modification methods, the realization methods of various modification methods in PRO/E are given, and the schematic diagram of the modified gear profile is given. Taking the solar wheel in NGW planetary transmission system as the research object, according to the existing gear modification formula, the formula for calculating the shape modification considering the parallelism error of the shaft installation is obtained after deformation. According to the change trend of tooth surface contact stress with modification, the calculation model is analyzed by Workbench module in ANSYS, and the rationality of the formula is verified.
