齿轮单啮仪及齿轮传动链检查仪一直采用的转位精度鉴定法有着连续测量及易于采用等优点。然而其通常的数据处理方法是不够满意的,因此它的应用及发展受到限制。本文讨论了差值误差谐波分析法及获得仪器误差曲线的方法。利用电子计算机作为分析工具,致使分析得以准确而迅速地进行。经实测分析,我们认为这些方法能准确地评定仪器的精度並能找出误差源。这对于该法的广泛应用具有实际意义。 Geometrical single gear and gear chain tester has been used in the indexing accuracy identification method has the advantages of continuous measurement and easy to use. However, its usual data processing method is unsatisfactory, so its application and development are limited. This article discusses the difference error harmonic analysis method and the method of obtaining instrument error curves. The use of computers as analytical tools led to accurate and rapid analysis. After the measured analysis, we think these methods can accurately assess the accuracy of the instrument and can find the source of error. This is of practical significance for the widespread application of the law.
