摘　　要：本文采用组合变形的分析方法，对锥体连接钎头工作时进行受力分析；运用叠加原理，推导出钎头尾部应点的应力状态表达式，按第三强度理论，建立了钎头裤口危险点的强度条件，并对得到的结论进行了分析。Using the combined deformation analysis method, the author mache an analysis of tapered bit forced in operating. The principle of superimposition was used to derive the expression of multiple-point stress state of shank end. According to the 3rd strength theory,the strength conditions of risk points at the bit socket collar were established,and the derived conclusions wer analyzed.
