一、前言齿轮检查中,公法线长度的测量不需要测量基准,不必严格控制测量基准和避免了由基准误差带来的测量误差.公法线长度的变动量表明齿轮的运动偏心——评定运动精度;公法线平均长度偏差能保证齿厚和控制侧隙:相差一齿的公法线长度的差值就是基距.它可以确定齿轮的模数和压力角:影响公法线长
I. Preface In gear inspection, the measurement of the length of the common normal does not require a measurement reference, and it is not necessary to strictly control the measurement reference and avoid the measurement error caused by the reference error. The variation of the length of the common normal indicates the eccentricity of the motion of the gear - ; The average length of the common normal deviation to ensure tooth thickness and control backlash: the difference between the length of the common law of a tooth is the base distance. It can determine the gear modulus and pressure angle: the impact of public law line length
