摘　　要：转盘轴承载荷分布分析是转盘轴承承载能力分析、承载曲线绘制、转盘轴承设计和选型的基础。首先建立轴承的静力学模型,求解出轴承在不同载荷下的载荷分布,其次分析了轴承在不同载荷状态下的载荷分布特性以及转盘轴承参数对载荷分布的影响。结果表明,转盘轴承在不同的载荷状态下,轴承两个接触滚道上的载荷分布特性不同,增大接触角、减小沟曲率半径系数,轴承滚道上的接触载荷有所降低,有利于提高轴承的承载能力。The load distribution analysis is the foundation of carrying load capacity analysis, the drawing of static carrying load capacity curve, designing and selecting of slewing bearing. Firstly, the static model of the bearing is es- tablished and the load distributions are solved at different loads. Then the characteristic of load distribution of bearing is analyzed, and also the influence of bearing parameters on load distribution is analyzed. Results show that the char- acteristics of load distributions on raceway are different at different loads. With the increase of contact angle and the decrease of the groove curvature radial coefficient, the loads on raceway decrease and the load - carrying capacity of bearing increases.
