本标准参照采用ISO4156-1981R圆柱直齿渐开线花键一米制模数一齿侧配合一总论、尺寸和检

验》标准的第二部分“尺寸”。

1主题内容与适用范围

本标准规定了45。标准压力角圆齿根(以下简称450圆齿根)的圆柱直齿渐开线花键所需的全部花

键尺寸，

本标准适用于GB/T3478.1标准中规定的压力角为450,模数为。.25至2.5mm,齿侧配合的渐开

线花键。

本尺寸表是按GB/T3478.1表3计算公式和齿侧配合为H/h、并采用基本检验方法编制的。

3.1450圆齿根，模数为。.25至2.5mm，公差等级为4,5,6和7级的花键尺寸表，见表1至表18,

3.2内花键小径D;的极限偏差和外花键大径D。的公差，见GB/T3478.1表25,

3.3内花键大径D。和外花键小径D;的公差，从GB180。标准公差IT12,IT13或IT14中选取。

34用展成法加工内、外花键时，齿根圆弧半径是变化的，本标准给出的是齿根国弧最小曲率半径，见

GB/T3478.1表26,

3.5当选择的检验方法不为基本方法时，其作用齿槽宽最大值、实际齿槽宽最小值、作用齿厚最小值和

实际齿厚最大值按下式计算:

作用齿槽宽最大值E-=E、二一3;

实际齿槽宽最小值E-0Evmi。十七

作用齿厚最小值Svmm=S-+A;

实际齿厚最大值S...=Svm..-.1.

3.6当花键齿侧配合类别不为H/b时，尺寸表中外花键的尺寸应按下式计算:

作用齿厚最大值Svm..=S+esv;

实际齿厚最小值S.,.=易.二一(T+1).

式中:esv—作用齿厚的上偏差，见GB/T3478.1表23;

(T+A)—总公差，见GB/T3478.1表7至表15.
