摘　　要：为了分析滚动直线导轨安装基面偏差对其寿命的影响 ,为导轨安装基面偏差的制定提供理论依据 ,以滚动直线导轨副的刚度计算理论为基础 ,推导了存在安装基面偏差时沟槽处法向接触变形及法向反力的计算方法。在此基础上 ,根据滚动直线导轨系统寿命的计算方法 ,推导了存在安装基面偏差时 ,导轨系统寿命的计算公式 ,并编制了相应的程序 ,绘出了不同预压时导轨寿命随安装基面偏差的变化曲线。The aim of this paper is to analyse the effect of base plane misalignment on life in order to provide a theoretical basis for the base plane misalignment formulation. Based on the stiffness calculation theory for linear rolling guide, we deduced the calculation method of groove normal touch deformation and the reacting force in the condition of the base plane misalignment. Furthermore, in accordance with the calculation method of specified life of linear rolling guide system, we derived the calculation formula for the life of the guide system. We worked out the calculation procedure and draw the life curve with change of the base plane misalignment under different preloading. The necessity that the base plane misalignment must be controlled within an allowable value is recommended.
