摘　　要：高速脂润滑角接触球轴承在机床和加工中心等领域应用广泛。为实现国产化代替,通过建立高速脂润滑角接触球轴承拟动力学模型,以离心力、轴向刚度、旋滚比、接触应力为目标函数,对轴承接触角、沟曲率系数、滚动体直径、滚动体数量和材料等结构参数进行设计研究,并对设计后的H7020-2RZ轴承进行温升性能和极限转速试验,结果表明满足要求。High-speed grease lubricated angular contact ball bearings are widely used in machine tools and machining centers.In order to realize the localization substitution,by establishing a quasi-kinetic model of high-speed grease-lubricated angular contact ball bearings,taking centrifugal force,axial stiffness,rotation ratio and contact stress as the objective function,the structural parameters such as bearing contact angle,groove curvature coefficient,rolling element diameter,and number of rolling elements are designed and studied,and the temperature rise performance and limiting speed test of the designed H7020-2RZ bearing are carried out,and the results show that they meet the requirements.
