摘　　要：主齿垫片预选机主要用于汽车驱动桥主动锥齿轮总成装配时选择调整垫片,调整垫片厚度对圆锥滚子轴承的轴向力分配有很大影响。为了方便测量简化模型与实际装配工况存在的差别,文章对测量模型进行分析补偿,考虑不同工况下的标准不确定度对测量精度的影响,使测量模型更为合理,从而提高测量精度。The preselection machine of gaskets is used for selecting the adjusted gaskets in assembling the initiative taper gear axis of the automobile's driving axle. The thickness of the adjusted gasket has a great effect on the distribution of the axial force of the taper roller axletree.As the simplified model for easy measuring can not reflect the true assembly's situation, the measuring models are analyzed and compensated in the paper,and the effects of different lubricative situations and the standard uncertainty of the inputting data on the measuring precision are considered. As a result,the measuring model is improved,and better measuring precision obtained.
