摘　　要：分析了渐开线样板测量装置测量Y7125磨齿机渐开线凸轮时主要的不确定度来源,并在对各不确定度分量评定的基础上,给出了测量扩展不确定度。评定结果显示,渐开线样板测量装置的测量不确定度为0.45μm,其中基圆轮和芯轴安装偏心所产生的误差是测量不确定度最主要的来源,测量装置满足高精度渐开线凸轮的测量精度要求。The main source of uncertainty of measurement while the involute master measuring apparatus measur- ing the involute cam which in the Y7125 grinder is analyzed, and on the basis of evaluating the uncertainty compo- nents, the expanded uncertainty is given. The result of evaluation shows that the measurement uncertainty of the invo- lute master measuring apparatus is 0.45 μm. And the eccentric mounting error of basic circle wheel and mandrel is the main source of uncertainty of measurement. The measurement precision of the measuring apparatus could meet the re- quirements of measuring high precision of involute cam.
