摘　　要：针对准确测量正交面齿轮的传动误差,减小测量过程中面齿轮安装误差对测量结果影响的问题,对既有偏置距又有加工误差的正交面齿轮进行了数学建模,并采用了TCA分析方法,研究了偏置距对带有加工误差的正交面齿轮传动误差及接触轨迹的影响规律,确定了最大偏置距范围。对不同偏置距下的面齿轮传动误差进行了测量实验,得到了一系列传动误差实测曲线及面齿轮一齿切向综合偏差。研究结果表明:面齿轮沿轴向上偏对传动误差影响不大;面齿轮沿轴向下偏时,面齿轮一齿切向综合偏差增大8.086μm;齿轮相对于小齿轮左右偏时,对传动误差无明显影响,面齿轮一齿切向综合偏差偏移量在1μm之内;这一结果对面齿轮传动误差测量中如何减小安装误差对测量结果的影响具有指导意义。Aiming at the problem of accurately measuring the transmission error of the face gear and reducing the influence of the face gear installation error on the measurement result during the measurement process the orthogonal face gear mathematical model with both offset dis tance and machining error was established. The TCA analysis method was adopted. The influence of offset distance on the transmission error and contact trajectory of orthogonal face gear with machining error was studied. The maximum offset range was determined. The measurement experiment of the face gear transmission error under different offset distances was carried out and a series of transmission error measurement curves and tangential comprehensive deviation of one tooth of face gear were obtained. The results indicate that when the face gear is shifted upward in the axial direction it has little effect on the transmission error. When the face gear is shifted downward in the axial direction tan gential comprehensive deviation of one tooth of face gear is increased by 8. 086 μm. When the face gear is biased to the left and right of the pinion gear there is no significant influence on the transmission error and tangential comprehensive deviation of one tooth of face gear is within 1 μm. This result has guiding significance on how to reduce the influence of installation error on the measurement results of face gear transmission error.
