分析了GBT4459.3-2000《花键表示法》中有关矩形花键和渐开线花键在径向、轴向视图上的画法及尺寸标注法、花键联结的画法,并对新国标新增的两种花键的符号及其标记中各参数和标注方法作了介绍。
The drawing and dimensioning method of spline and involute spline in radial and axial view of spline representation of GBT4459.3-2000 are analyzed, and the spline coupling method is also introduced. The two kinds of new national standard spline symbols and markings in the parameters and labeling methods were introduced.
