As the key parts of the crankshaft mud pump, the qualiW of directly is related to product quality.This paper to oil drilling five cylinder pump for targets of 3D modeling, variable condition in the operation of the conditions of crankshaft stress, numerical analysis the fa tigue strength, points out that the danger of running the boundary conditions. This paper studies the results to the other mud pump provides reference for the design of the crankshaft.曲轴作为泥浆泵关键零件，其质量的好坏直接关系到产品的优劣。论文以石油钻井五缸泵为对象进行了三维建模，在变工况的运行条件下研究了曲轴的应力，数值分析了曲轴疲劳强度．指出其运行的危险边界工况。其研究结果可为其他钻井泵曲轴的设计提供参考。
