Pitch is a combination number of a one-to-two ratio indicating the spline proporti******; the upper or first number is the diametral pitch, the lower or second number is the stub pitch and denotes, as that fractional part of an inch, the basic radial length of engagement, both above and below the pitch circle.

径节分数：径节分数是由两个数组成的一个比率，它表示的是花键的比例；设这个比率为A/B，则在这个分数中第一个数A表示的是花键的径节，第二个数B表示的是残余径节，径节表示的是在节圆上方的键齿在半径方向上的结合长度，残余径节表示的是在节圆下方的键齿在半径方向上的结合长度。

Stub Pitch is a number used to denote the radial distance from the pitch circle to the major circle of the external spline and from the pitch circle to the minor circleof the internal spline.
