摘　　要：论述了设计、制造和使用固定安装突起滚刀加工采煤机磨前圆柱齿轮的方法。比较了2种最普通固定安装滚刀的形式及寿命,通过试验验证了固定安装突起滚刀是一种经济型滚刀,突起廓形角对滚刀寿命有重要的影响,合理选择该角度能够有效地提高滚刀寿命。It discussed the method-to design, manufacture and use fixed installation protruding hob to process milling front cylindrical gear of excavating coal machine. It compared the form and life of two kinds of the most ordinary fixed installation hob. By testing, it confirmed that fixed installation protruding hob was a kind of economy hob, protruding shape angle was importance for hob life, and it could improve hob life effectively to select reasonably this angle.
