摘　　要：依据齿轮参数和几何尺寸,基于范成法加工齿轮原理,建立了根切齿轮齿根过渡曲线和轮齿渐开线的参数方程,准确绘制出根切齿轮齿形图;并用Matlab软件编制程序,精确计算了齿根最小弦齿厚和最大根切半径。为建立根切轮齿的有限元模型、量化分析根切齿轮齿根弯曲疲劳强度与变位系数的关系、确定根切齿轮的最佳变位系数、研究根切齿轮在工业生产中应用的可行性等提供了可靠依据。According to the parameters and geometric dimensions of the gear,the parametric equations of the transition curve and involute line of the root cutting gear are established based on the principle of machining the gear with the generating method,the tooth shape diagram of the root cutting gear is accurately drawn,and the minimum chord tooth thickness and maximum root cutting radius are accurately calculated with the Matlab software.It provides a reliable basis for establishing the finite element model of the root cutting gear,quantifying the relationship between the bending fatigue strength and the displacement coefficient of the root cutting gear,determining the best displacement coefficient of the root cutting gear,and studying the feasibility of the use of the root cutting gear in the industrial production.
