摘  要:
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.
