所谓留磨花键滚刀,是指花键滚刀切出的花键轴的键侧和底径(内定)是要留磨的(见图1),留磨量为a。对于以外径D定心的花键轴来说,留磨主要是指花键轴的键侧留磨量的大小,至于外径D留磨量大小与花键滚刀无关,本文不讨论。对于内径d定心的花键轴采说,留磨主要是指在花键轴键侧留磨量大小和底径的留磨量大小。由于留磨花键滚刀键侧和底径留磨量大小的确定还没有标准化,全国各工具厂根据自己厂的经验各自
The so-called grinding mill spline hob, refers to the spline hob cut out of the spline shaft key side and bottom diameter (default) is to keep grinding (see Figure 1), leaving a grinding amount of a. For the spline shaft centering on the outer diameter D, the main part of the spindles is the size of the spline shaft, which is not related to the spline hobs, which is not discussed in this article. For the inner diameter of the spline shaft d centering said that the main means to stay grinding spline shaft key to keep the amount of grinding size and bottom diameter of the remaining grinding size. As grinding mill spline hob key side and bottom diameter to determine the size of the remaining grinding has not standardized, the country’s tool factory according to their own plant experience each
