【摘要】：在齿轮整体误差测量技术中,整体误差测量结果与齿轮单项误差测量仪器的结果之间存在差异的问题一直没有得到很好的解决。通过对齿轮整体误差测量中异点接触现象的分析,提出了异点接触误差的定义和计算方法,分析了异点接触误差和曲率干涉误差在本质上的不同之处,提出了基于准形态学滤波的异点接触误差修正方法,并进行了异点接触误差修正的仿真试验和实际整体误差测量结果的误差修正试验。理论分析和试验数据表明,修正后的整体误差测量结果更加接近实际被测齿廓的真实形状,应用本方法修正异点接触误差的效果显著,可提高整体误差式齿轮量仪的测量精度。
[Abstract]:In the whole gear error measurement technology, the problem of the difference between the whole error measurement result and the result of the gear single error measuring instrument has not been solved well all the time. Based on the analysis of different point contact phenomenon in gear integral error measurement, the definition and calculation method of different point contact error are put forward, and the essential difference between different point contact error and curvature interference error is analyzed. In this paper, a method for correcting the error of different point contact based on quasi-morphological filtering is proposed, and the simulation experiment of the correction of the error of the different point contact and the error correction test of the actual whole error measurement result are carried out. The theoretical analysis and experimental data show that the measured results of the corrected overall error are closer to the real shape of the measured tooth profile. The effect of this method on correcting the hetero-point contact error is remarkable and the measuring accuracy of the gear measuring instrument with integral error can be improved.
