摘　　要：根据牙轮钻头浮动环轴承结构,建立其有限元模型和边界条件,按轴承结构的尺寸及间隙比(分别为1/3,1,2,3,4,5)进行了浮动环应力及工作状态的动力仿真计算,结果与文献[1]中的试验结果基本一致,这为浮动轴承的设计提供了一种行之有效的方法。According to the structure of nonlocating bearing used for roller bit,this paper has built its finite element model and boundary conditions,and then simulates and computes the stress of the floating ring and its working conditions according to the bearing structural dimension and its gap ratios （ they are separately 1/ 3,1,2,3,4,5 ）. The results accord with that from literature 1,and this provides an efficient approach to design the nonlocating bearing.
