摘　　要：基于齿轮的范成加工原理,提出了一种变速比齿扇齿廓的定中心距齿轮建模法。该方法不使用啮合方程,只需要确定齿条的参数及变速比运动规律,就可快速地得到变速比齿扇的三维数模。给出了应用该方法完成变速比齿扇齿廓设计计算的实例。分析表明该方法简洁明了,实用性强;适合于非圆齿轮齿廓设计计算,尤其适合于变速比转向器齿扇齿廓的设计计算。Based on the principle of gear machining generating method, a modeling method - variable center distance gear modeling method for variable ratio gear sector profile is put forward. With a given rack parameter and required variable ratio transmission, variable ratio gear sector 3D model could be quickly obtained. An example of designing and calculating variable ratio gear sector profile by the method is given. The analysis shows that the method is concise, practical, and it is suitable for noncircular gear tooth profile design and calculation, especially for the variable ratio steering gear tooth profile design and calculation.
