摘　　要：基于有限元ANSYS软件,对负间隙回转轴承进行了静力学分析。通过改变钢球的直径来改变间隙,研究了回转轴承在一定轴向载荷和倾覆力矩作用下,其内外圈滚道和钢球的位移和应力分布情况,从而得到内外滚道的最大接触应力与负间隙之间的关系,并与理论计算的结果进行对比,验证了该有限元法的可靠性。Based on the FEM and the relative software ANSYS,the analysis of slewing bearings with negativeclearance was presented. In this paper,the stress distribution of slewing bearings under condition of different loadshas been studied. The clearance has been changed by altering the ball diameter,thus the relationship between thecontact stress of the inner raceway and balls and the clearance has been received. Subsequently,compared to thecalculation results based on some theoretical models from others,the reliability of the FEM can be verified.
