为了生成摆线齿锥齿轮的三维实体模型,以验证摆线齿锥齿轮的设计参数和切齿加工参数,分析了Klingelnberg齿制摆线齿锥齿轮切齿加工的基本原理,以AutoCAD 2008为开发平台,运用ActiveX Automation技术和VBA编程语言,建立了基于尺寸驱动的齿坯和产形轮的实体模型。基于摆线齿锥齿轮的切齿加工原理以及切齿过程中产形轮与齿坯之间的相对位置、相对运动关系,通过产形轮与齿坯之间的相减布尔运算模拟了切齿加工过程,通过仿真实例验证了仿真算法的正确性。研究结果表明,切齿加工仿真系统对建立齿轮的三维实体模型,验证齿轮的设计参数和切齿加工参数具有重要的意义。

In order to create three dimensional solid models,verify designing parameters and machine setting parameters for cyclo-palloid bevel gears,the machining principle of cyclo-palloid bevel gears with Klingelnberg tooth system was analyzed.Based on AutoCAD 2008 development platform,using ActiveX Automation technology and VBA programming language embedded in AutoCAD,the dimension-driven solid model of the workpiece and generating gear was established.Based on the machining principle of cyclo-palloid bevel gears,the relative position and movement between the workpiece and generating gear,the cutting process was simulated by subtraction boolean operation between workpiece and generating gear.The correctness of simulation system is validated by comparing simulation result with practical machining workpiece.The machining simulation system is meaningful for generating precise three dimensional solid models and verifying machine settings.
