摘　　要：依据圣维南原理,对某型号采煤机摇臂滚筒处复杂力进行了平移简化,对联接过渡架和摇臂的联接件双头螺柱及销轴进行了受力分析及相应的强度计算,结果表明双头螺柱及过渡架强度均满足采煤机使用要求。According to Saint Venant principle, the complex load of cutting drum of shearer loader is removed and simplified. Load and strength of double-screw bolt and pin shaft are analyzed, it shows that the strength of double-screw bolt and transition structure meets the use requirement of shearer.

关 键 词：过渡架 双头螺柱 销轴 强度分析
