摘　　要：加工仿真是验证加工方法和研究加工精度的重要手段,基于三维建模软件和专用软件的加工仿真存在实现复杂、仿真精度低等缺陷,针对变厚齿轮的连续展成磨削这一新工艺,在分析锥形蜗杆设计以及锥形蜗杆磨削变厚齿轮运动的基础上,建立了锥形蜗杆的数学模型,并且建立了锥形蜗杆磨削变厚齿轮的数字仿真模型。以某一变厚齿轮为例,将变厚齿轮理论模型与数字仿真模型进行对比,验证了所建立的仿真模型的准确性。所建立的锥形蜗杆加工变厚齿轮的数字仿真模型为变厚齿轮连续展成磨削精度的研究以及复杂修形变厚齿轮连续展成磨削精度方法的研究奠定了基础。Machining simulation is an important means to verify machining methods and study machining accuracy. The machining simulation based on three-dimensional modeling softwares or some special softwares has two defects that are complexity and low accuracy. For the new process of the continuous generating grinding of beveloid gears, the mathematical model and the digital simulation model of a conical worm wheel grinding a beveloid gear were established in the basis of the analysis of a conical worm wheel design and the motion of a conical worm wheel grinding beveloid gear. Taked a beveloid gear as an example and compared the theoretical model of the beveloid gear with the digital simulation model. The results verify the accuracy of the model. The established digital simulation model has a great significance for the accuracy research of a conical worm wheel grinding a beveloid gear and the research for continus generating grinding of beveloid gears with complex modification.
