摘　　要：依据钻孔设备高速滚珠轴承动态特性的辅助方程,进行了根本变量的分析,得到了各个方程组变量相互耦合的关系图和根本变量。通过高速滚珠轴承受纯轴向力时的应用接触角,给出了进行迭代求解动态特性的计算方法和具体步骤。又根据文献的计算结果,分析了随着载荷和转速的变化内接触角和外接触角增量的关系,以及接触角增量关系的成因。并应用本文提出的迭代方法对算例进行了计算,结果验证了对接触角增量变化分析的正确性,从而将接触角的搜索范围缩小一半并更加接近真实解。The paper analyzes the ultimate variables and acquires the relationship and ultimate variables according to the auxiliary dynamic equations of high-speed ball bearing in drilling equipments. It provides the calculation methods and steps of solving dynamic characteristics by iterative methods, with its applicable connecting angle of the bearing with axial load. Hence, it analyzes the incremental relationships of inner and outer connecting angle and its causes. Finally, the example is calculated by the iterative method in the paper, the result proves the true of this analysis, and it makes the search band of the connecting angle reduce a half and reach the true value a lot.
