摘　　要：为了解机床主轴转子中高速角接触球轴承的生热机理及其动力学特性,从轴承运动学出发,分析了变转速下轴承惯性载荷与热载荷对轴承外圈的弹性变形量的影响。通过定量对比,明确了热载荷对轴承游隙变化的主导作用,并研究了某型号数控机床主轴在低转速下的温度场。To understanding the heat generation mechanism and dynamic characteristics of the high-speed angular contact ball bearings in machine tool spindle rotor systems,this paper analyzes the influence of bearing inertia load and thermal load on the elastic deformation of bearing outer ring under variable speed according to bearing kinematics.Through quantitative comparison,the dominant role of thermal load on the change of bearing clearance is clarified,and the temperature field of a certain type of CNC machine tool spindle at low speed is studied.
