摘　　要：在渐开线凸轮和档块式展成磨齿机中,渐开线凸轮的面向误差对被磨齿轮的齿形精度有较大影响。在分析双基圆盘渐开线凸轮磨削装置工作原理的基础之上,应用UG/WAVE技术与装配上下文设计,采用自顶而下与自下而上相结合的装配建模方法,建立渐开线凸轮磨削装置的参数化模型,并对其进行了可视化运动仿真。在改进模型的运动仿真中,导出了不规则类圆体在直线导轨上作纯滚动时的运动仿真驱动函数,并进行了仿真验证。The contour error of involute cam has greater influence to the profile accuracy of grinding gear in generating gear grinder with involute cam-link stopper. On the analysis of work principle about grinding device of double-disc involute cam,used the technology of UG/WAVE,the context assembly design and the modeling methods of top-down assembly integrated with bottom-up assembly,the parameterized model is found and the visualized motion simulation was conducted. ,the driving functions of motion simulation when the irregular circle make pure rolling along linear guide were deduced and the results of simulation were tested during the simulation of improved model.
