查询词典 improper fractional function

The numerator in this fractional designation is known as the diametral pitch and controls the pitch diameter; the denominator, which is always double the numerator, is known as the stub pitch and controls the tooth depth.

在这一系列的分数中的分子是径节，径节的大小决定了节圆的直径；而分数中的分母通常是分子的两倍，分母是残余径节，它的作用是控制齿槽的深度。

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。

Tooth Proportions.—There are 17 pitches: 2.5/5, 3/6, 4/8, 5/10, 6/12, 8/16, 10/20, 12/24, 16/32, 20/40, 24/48, 32/64, 40/80, 48/96, 64/128, 80/160, and 128/256. The numerator in this fractional designation is known as the diametral pitch and controls the pitch diameter; the denominator, which is always double the numerator, is known as the stub pitch and controls the tooth depth. For convenience in calculation, only the numerator is used in the formulas given and is designated as P. Diametral pitch, as in gears, means the number of teeth per inch of pitch diameter.

齿比——一共有17种齿比：2.5/5，3/6，4/8，5/10，6/12，8/16，10/20，12/24，16/32，20/40，24/48，32/64，40/80，48/96，64/128，80/160和128/256在这一系列的分数中的分子是径节，径节的大小决定了节圆的直径；而分数中的分母通常是分子的两倍，分母是残余径节，它的作用是控制齿槽的深度为了方便计算，在所有的公式中都使用分子作为计算参数，并且与齿轮的表示方式一样定义为径节P尺寸，也就是在节圆上，每英寸长度上的齿数
