摘要： 根据渐开线螺旋面上存在渐开线、螺旋线与直母线三族特征线的性质，提出基于直母线族误差的大齿轮在机综合测量原理。以刃边齿条为工具，测量廓面的直母线族误差，通过误差处理与分析获得齿廓总偏差和螺旋线总偏差。测量方案以机床基准为测量基准，并克服了大齿轮惯性大、运动控制困难的缺点，具有测量精度高和操作简单等特点。最后，以试验验证了该测量原理的正确性与技术的可行性。

Abstract: According to the characteristic that there are three families of curves, that is, involute family, helix family and straight generatrix family on the involute helicoid, the measurement principle based on the error of straight generatrix family is put forward. Taking the straight-line-rack as the tool, the error of straight generatrix is measured, and by error analysis, the tooth profile error and tooth orientation error can be obtained. This kind of measuring method takes the benchmark of the machine tool as the measuring one, and overcomes the problem that the weight and the inertia of the large gear are big and the control of its motion is difficult, so there are the advantages of high measuring accuracy and convenient operation. At last, the experiment has been done, which indicate that the principle is correct and the technology is practicable.

Key words: Large gear, Measurement on-line, Spiral line total deviation, Straight generatrix error, Tooth profile total deviation
