摘　　要：在标准齿轮若干精度指标的检测中,渐开线齿廓检验是一个重要且难度较大的检测项目,双盘式渐开线测试仪就是测量标准齿轮渐开线齿廓的高精度仪器之一。本文简要介绍了双盘式渐开线测试仪的测量原理,并利用采样定理着重分析了在测量过程中的数据采样问题,为渐开线齿廓检验中采样间隔的确定提供了依据。The technology of involute tooth profile measurement for a master gear is important and difficult in all its precision indexs. The double-disc measuring apparatus for involute tooth profile was provided with high accuracy. In this paper, we first introduce the principle of the measuring apparatus and then analyzes the problem of data sampling in measuring process with the sampling theorem. Finally, we offer a referrence for sampling interval in measurement of involute tooth profile.
