外插齿刀设计的新方法

A New Method of the Design About the External Gear Shaper Cutter

叙述了外插齿刀设计新方法的基本原理、转换后插齿刀变位系数选择的各限制条件、限制区域的形成及其与插齿刀齿顶圆半径计算曲线之间的关系， 并通过实例介绍了其设计步骤． 该方法克服了传统设计方法的缺点， 不但应用范围广、计算简单、设计效率高而且可判断设计的可行性．

The paper introduces the basic principle about the new designing method of the external gear shaper cutter,limited condition of the transformed cutter displacement factor,the formation of the limited ared and its relationship with the calculation curve of the cutter tip-circle’s radius.It also introduces the procedures by the actual example.This method overcomes the defect of the traditional design.It not only has wide applications,is simple in calculation and high efficient,but also can judge the feasibility of the design.
