摘　　要：椭圆齿轮是一种典型的非圆齿轮,具有非均匀、周期性变化的传动比特性,在机床、轻工自动机械、仪器仪表等诸多领域中取得了良好的应用效果。椭圆齿轮的建模研究对于其推广应用具有重要意义。根据椭圆齿轮的结构特点,采用齿形折算法的原理,基于CREO进行了参数化建模,并以此为基础在ADAMS中构建了运动仿真模型,仿真结果表明椭圆齿轮副啮合传动情况与理论分析保持一致,证明了建模方法的可行性,为椭圆齿轮的数控加工提供了基础的技术依据。Elliptic gear is a typical non circular gear,with transmission ratio characteristics of heterogeneity and periodic variations,bringing excellent effects in practice such as machines,light industrial automatic machinery,instrumentation and other fields. The study on its modeling has an important significance for its popularization and application. According to the structural characteristics of elliptic gear and tooth profile conversion method,parametric modeling was carried out based on CREO,and motion simulation was constructed in ADAM S. The simulation results showthat elliptic gear pair meshing transmission case is the same as theory analysis. This proves the feasibility of the modeling method,and provides the technical basis for the numerical control machining of elliptic gear.
