摘要温度作为影响几何量精密测量的主要因素之一,其在长度测量不确定度评定中占有较大的影响分量。分析了温度对齿轮的齿廓倾斜偏差、螺旋线倾斜偏差和齿厚偏差的影响,建立了温度和齿轮主要被测参量的几何关系,验证了温度变化对不同尺寸的齿轮测量结果的影响。为超精密齿轮测量误差受温度的影响分析提供了理论依据,有助于实验室根据测量准确度的要求选择相应的测量温度。

Abstract：As one of the main effect factors in the process of precision measurement for the geometric quantities, temperature accounts for much more in the evaluation of measurement uncertainty.The temperature effects on profile slope deviation,helix slope deviation and tooth thickness deviation are analyzed through typical example,and the geometric relationship between the temperature change and the measurand of master gears is established,meanwhile the effect on the temperature change and measurement results of the gears with different dimensions is also proved.The necessity of improving gear measuring conditions is clarified,and theory evidence on the analysis for precision gear measurement is provided,which is contribute to the different Labs to determine measurement conditions based on gear accuracy grades.

Key words： Metrology Measurement accuracy Profile slope deviation Helix slope deviation Tooth thickness deviation
