双面齿轮滚动试验在车间高速齿轮测量中得到广泛应用，但测量结果会受到测量力的影响。提出了一种利用测力测量齿轮齿径向变形的算法。数值计算结果考虑了不同测力和不同材料的影响。采用有限元方法分析了测量力对径向齿面变形的影响。在试验机上进行了0.5~4N不同测量力下的径向变形实验，得到齿对齿径向综合偏差的变化量为3.0µm，而在MatLab中的变化量为6.12µm，与ISO 1328-2：1997相比，产品齿轮精度等级的偏差为11~10级。该算法可用于计算双面齿轮滚动试验中测量力对齿轮径向变形的影响。
Double-flank gear rolling test is widely used in high speed gear measurement in workshop, but the measurement results may be influenced by measurement force. An algorithm is proposed for gear tooth radial deformation by measurement force in the test. The numerical results calculated in MATLAB considers different measurement forces and materials. Finite Element Method (FEM) used analyzes the radial tooth deformation under the influence of the measurement force. The maximum difference of radial deformation between the two methods is 0.1 mu m. Experiments are carried out on a tester under different measurement force varying from 0.5 N to 4 N. The variation of tooth-to-tooth radial composite deviation is 3.0 mu m, while the variation in MATLAB is 6.12 mu m. Compared to ISO 1328-2:1997, the product gear accuracy grade deviates from grade 11 to 10. The algorithm proposed can be used to calculate gear radial deformation influenced by measurement force in double-flank gear rolling test.
