摘　　要：两段式小型球磨机筒体依靠铰制孔螺栓连接,螺栓受交变载荷与冲击载荷作用,是生产中的危险部位。本文基于两段筒体连接处的螺栓在交变拉应力和切应力作用下的失效分析,建立了筒体连接螺栓设计模型,并验证了模型的正确性,为相关设计奠定了理论基础。The twosegment cylinder of small ball mill is connected by cylinder bolts which are the critical parts under the cyclic load and impact load in manufacturing. Based on failure analysis of the connecting bolts under the action of alternating stress and shear stress, the diameter calculation formula is established and the correctness of the model is verified by experiments, which offers a theoretical ba- sis for some concerned designs.
