摘　　要：提出一种考虑轴承套圈及其支撑结构弹性变形的大型转盘轴承接触载荷分布的计算方法。利用该方法分析了支撑结构弹性变形、轴承游隙及初始接触角对四点角接触球轴承接触载荷及接触角分布的影响。其结果与采用有限元方法得到的结果基本吻合,且计算效率大大提高。研究成果为定性分析大型转盘轴承的承载能力提供了理论依据。A newcomputation method is proposed for determining the load distribution in the rolling elements of a large slewing bearing accounting for the flexibility of the bearing ring and its supporting structures. The analysis of the effect of the elasticity of supporting structures,internal clearance and nominal carrying angle on the magnitudes of contact force and actual carrying angle of a four-point contact ball bearing is presented using the method,the results of which have been basically correlated with the results of FE method,and especially the computation efficiency is improved substantially. The above results provide theoretical basis for analyzing qualitatively the static capacity and fatigue lifetime of large slewing bearings.
