齿轮是现代工业中最重要的传递动力的机械零件之一,开发受力状况良好的新型结构一直是这一领域的研究前沿。圆弧齿线圆柱齿轮是一种新型传动机构,首先阐述了其成型原理,在坐标变换和空间啮合理论的基础上,推导其齿面方程。运用UG/grip语言,开发了符合实际加工过程的圆弧齿线圆柱齿轮的自动生成程序,实现了圆弧齿线圆柱齿轮理论模型的参数化造型,且分析得出了圆弧齿线圆柱齿轮副正确啮合的条件。 Gear is one of the most important mechanical components to transmit power in modern industry. It is always the research front in this field to develop a new type of structure under stress. Circular arc gear cylindrical gear is a new type of transmission mechanism. Firstly, the forming principle is described. Based on the theory of coordinate transformation and space engagement, the tooth surface equation is deduced. By using UG / grip language, an automatic generation program of circular gear was developed according to the actual machining process, and the parametric modeling of the theoretical model of circular gear was realized. The results showed that the circular gear, Proper meshing conditions.
