目前我国各单位使用的不同型号的齿轮渐开线检查仪反映出一个共同的问题是量值不统一,而且差别比较大,严重的影响到生产和科研工作的进行。去年在三个地区的渐开线仪器量值统一工作座谈会上讨论了这个问题,并提出以渐开线样板作为渐开线仪器的标准来统一量值。统一渐开线仪器量值现实可行的办法是采用渐开线样板对渐开线仪器进行校准,并加改正值使用仪器,这样可起到提高渐开线仪器的使用精度达到统一量值的目的。所谓加改正值使用仪器,就是用样板来消除渐开线仪器由于某种原因而存在的系统误差,这种误 At present, different types of gear involute tester used by various units in our country reflect that a common problem is that the values ​​are not uniform and the differences are relatively large, which seriously affect the progress of production and scientific research. Last year, this issue was discussed at the Workshop on Involutive Instrument Magnitude Unification in the three regions and proposed to unify the magnitudes with the involute template as the standard for involute instruments. The practical method of unifying the involute instrument is to adopt the involute model to calibrate the involute instrument and to use the instrument with a positive correction value so as to increase the accuracy of using the involute instrument to achieve a uniform magnitude . The so-called plus correction of the use of equipment, is to use the template to eliminate involuntary instruments for some reason the existence of systematic errors, such a mistake
