摘　　要：通过对空气潜孔锤反循环钻头球齿碎岩机理的分析,用半定量的方法对球齿的布齿进行了探讨,明确了球齿的布齿设计思路,先根据冲击功确定球齿数目,再进行合理的排列,最后到固齿方法的选择。Through the analysis of the ball-crushing mechanism of the air-drilling hammer reverse circulation drill bit,the semi-quantitative method is used to discuss the tooth of the ball tooth,and the design idea of the tooth of the ball tooth is clarified.Firstly,the number of ball teeth is determined according to the impact power,then make a reasonable arrangement,and finally choose the solid tooth method.
