齿轮机床传动链精度检查仪的精度鉴定,可以采用高精度光电检查仪或标准多角块。前者价格昂贵制造困难,后者只能得到少数断续点的静态精度,因此较普遍的采用“转位精度鉴定法”。该法最大特点是不需要精密仪器或标准块,只需传感器相对于齿轮工作台转位,或者二传感器同轴相对转位,测量后作数值差值处理即可。它有在使用运转状态下进行动态鉴定的优点,制造和使用单位都可采用。但是由于缺乏有效的数值处理技术,使鉴定的 Accuracy of gear machine chain accuracy tester identification, you can use high-precision photoelectric tester or standard multi-angle block. The former is expensive and difficult to manufacture, the latter can only get a small number of intermittent point of static accuracy, so the more common use of “indexing accuracy identification method.” The most important feature of this method is that no precision instrument or standard block is required, only the sensor is indexed relative to the gear table or the two transducers are indexed relative to each other. After the measurement, numerical difference processing can be performed. It has the advantage of dynamic characterization under operating conditions, both for manufacture and use. However, due to the lack of effective numerical processing techniques to make identification
