多齿分度台是靠两个多齿盘(鼠牙盘)进行分度定位的圆分度器。由于两个多齿盘相互啮合,在周向及径向同时定位,不受轴系精度的影响,所以它具有结构简单、分度精度和重复定位精度高、精度保持性好等优点。 多齿分度台不仅用于计量精密角度,而且还可用于加工有高精度角度要求的零件 Multi-tooth indexing table is based on two multi-gear (rat teeth plate) for indexing round positioning device. Because the two multi-gear intermeshing, positioning in the circumferential and radial at the same time, not affected by the accuracy of the shaft, so it has the advantages of simple structure, indexing accuracy and repeat positioning accuracy, accuracy and good retention. Multi-tooth indexing table is not only used to measure the precision angle, but also can be used for machining parts with high-precision angle requirements
