摘　　要：按照GB/Z 18620. 2-2008对齿轮副法向侧隙的定义和计算方法,在给定工作中心距的情况下,计算出齿轮副法向侧隙常数c。固定齿轮副中的一个齿轮,利用最大转角测量设备对另一个可转动齿轮的最大转角θ进行测量。齿轮副法向侧隙值由法向侧隙常数c与最大转角θ的乘积计算得出。以测量和计算某发动机用平衡轴总成齿轮副的法向侧隙为例,介绍测量设备,说明该设备可以用于测量封闭空间内齿轮副法向侧隙,并介绍了测量和计算的实现方法。说明测量误差来源并计算出测量误差大小。与塞尺直接测量法的测量结果进行对比,检验基于该方法测量结果的准确性。多次测量同一啮合齿的法向侧隙,确认基于该方法测量结果的一致性。Calculated the gear pair normal backlash constant c according to definition and calculationmethod of gear pair normal backlash from GB/Z 18620.2-2008 at a given work center distance. One gear of thegear pair is fixed,the max rotation angle θ of the another rotatable gear is measured by using max rotation anglemeasure equipment. Gear pair normal backlash is acquired by product of gear pair normal backlash constant c and max rotation angle θ. Taking the measurement and calculation of the normal backlash of the gear pair of abalanced shaft assembly for an engine as an example,the equipment can be used to measure the normal back-lash of gear pairs in the closed space is explained,the realization method for measure and calculation of thegear pair normal backlash introduced. The error source is explained and the error result is calculated. Comparedwith feeler gauge direct measure,the measured accuracy based on this method is verified. The normal backlashof the same mesh gear repeatedly is measured,the result consistency based on this method is verified.
