摘要
以齿侧面加工的铲磨工序为基础,建立了直槽硬质合金滚刀变偏距重磨的数值仿真模型。根据计算机模拟变偏距重磨的数据可知,变偏距重磨比等偏距重磨能较大地改善滚刀重磨后的齿形精度。文中的仿真模型亦可用于零前角及正前角齿轮滚刀重磨后的齿形误差计算和齿形的修正。
A numerical simulation model of variable offset regrinding for the carbide gear hobs with straight flutes is built based on the radial relief grinding in the final manufacturing procedure for them. From the results obtained from the computer's simulation for the procedure of variable offset regrinding, it is shown that the approach of variable offset regrinding can improve the tooth profile accuracy of the hob more greatly than constant offset regrinding. The mathematical model developed can be used in the regrinding of gear hobs with zero rake angle and positive rake angle for error estimation and revision as well.
