矩形花键联接采用内径定心方式,其定心精度高,但制造则较外径定心困难。常用的花键轴加工方法是在专用花键轴铣床上用花键滚刀进行加工。在缺乏专用花键轴铣床的情况下,可在普通卧式铣床上利用分度头进行加工,用成形铣刀代替花键滚刀。这种加工方法生产效率虽然较低,但成形铣刀回转面的截形与工件横断面截形可加工成一致,只要分度准确,加工的花键轴精度较高,对于一些要求刀
Rectangular spline connection using the inner diameter centering method, the centering accuracy, but the manufacturing is more difficult than the outer diameter centering. Spline shaft commonly used method of processing is in a special spline shaft milling machine with spline hob processing. In the absence of special spline shaft milling machine, can be used in ordinary horizontal milling machine indexing head processing, forming cutter instead of using spline hob. Although the production efficiency of this processing method is low, the truncation of the forming surface of the milling cutter and the cross-section of the workpiece can be machined to be consistent. As long as the indexing is accurate and the precision of the splined shaft is high,
