若表 4、6、8、10、12、14、16、18、20、22、24、26、28、30、32 中未给出公法线长度值,则应按滚柱进行测量,因为测量面位于曲率半径附近或齿顶棱边附近时,公法线长度测量不可靠。
-
表 4、6、8、10、12、14、16、18、20、22、24、26、28、30、32 中给出的公法线长度偏差系数值均为 0.866。

5. 公差与配合
5.1. 按齿侧面定心时的公差与配合
5.1.1. 花键套齿槽宽度 e 和花键轴齿厚 s 的公差带位置,以及公差、基本偏差和极限偏差的标注,应符合图 5 的规定。
图 5。花键套齿槽宽度 e 的公差带位置;花键轴齿厚 s 的公差带位置
花键套齿槽宽度和花键轴齿厚的极限偏差应从其在分度圆弧上的公共公称尺寸起计算。
5.1.2. 规定花键套齿槽宽度和花键轴齿厚有两种公差:
Ts——齿槽宽度本身(齿厚本身)的公差,在不使用综合量规的情况下单独检验;
T——综合公差,包括齿槽宽度(齿厚)本身的偏差以及齿槽(齿)齿形要素的形状和位置偏差,用综合量规检验。
5.1.3. 规定连接要素的下列精度等级,用以确定花键套和花键轴的 Ts 和 T 值,并以数字表示:
花键套齿槽宽度——5、6、7、9、11 级;
花键轴齿厚——5、6、7、8、9、10、11 级。
Ts 和 T 的公差值见附录 2 表 1。
(修改版,修改单第 2 号)
5.1.4. 规定下列基本偏差系列,用拉丁字母表示(小写字母表示轴,大写字母表示套):
花键套齿槽宽度——H;
花键轴齿厚——r、p、n、k、h、g、f、d、c、a。
花键轴齿厚的基本偏差值见附录 2 表 2。
5.1.5. 规定尺寸 e 和 s 的公差带标注方式为:先写表示精度等级的数字,后接表示基本偏差的字母(这与光滑连接中数字写在字母之后的标注方式不同)。
5.1.6. 花键套齿槽宽度和花键轴齿厚的公差带应符合表 33 的规定。

7. 检验方法
7.1. 内花键和外花键的要素采用综合量规或单项量规进行检验。
图 7 给出了渐开线花键连接的 3 种检验方法。
图 7. 渐开线花键连接的检验方法
标准检验方法采用通端综合量规和止端扇形量规进行(检验综合公差 T)。
公差 Ts 作为参考值确定,不用于零件的合格判定或报废判定。
7.2. 替代方法 A 通过通端综合量规、止端扇形量规和综合量规进行检验。
该方法用于保证最大有效侧隙。
7.3. 替代方法 B 适用于不需要检验花键形状和位置误差的场合。
7.4. 花键连接采用通端综合量规和止端单项量规进行检验。
综合量规应在自重作用下通过被检表面。用综合量规检验花键轴或套筒时,量规处于一个位置即可,无需重新装夹。
用止端单项量规检验时,应至少在三个不同位置进行。若止端单项量规在其中任一位置能够通过,则判定该被检零件为不合格品。也允许用测量滚柱代替止端单项量规对花键轴和套筒进行检验。
若综合量规的长度小于被检表面长度的 0.5 倍,则还需另外检验产品齿侧面的平行度偏差。推荐的公差值见附录 2。
对于第 6 级及更粗公差等级的花键轴和套筒的检验,应采用 3 级精度的量规;对于第 8 级及更粗公差等级的检验,应采用 4 级精度的量规。
第 7 节。(新增,第 2 号修改单)。
附录 1(参考性)。根据所用刀具类型选择花键连接参数 Hf 和 hf 的数值
-
渐开线花键连接的公称(原始)直径 d 通常应等于滚动轴承孔的公称直径。
-
套齿根圆直径 df 和轴齿根圆直径 df1 的数值,在齿根高 Hf=hf=m 时为公称值。
-
采用通用刀具加工时,套的齿根圆直径相对公称值增大 0.2m,即 Hf=1.2m。
-
采用通用刀具加工时,轴的齿根圆直径相对公称值减小 0.1m(采用蜗杆铣刀加工时)或 0.2m(采用插齿刀加工时)。此时轴的齿根高相应取为 hf=1.1m 和 hf=1.2m。

2. 极限偏差的计算
2.1. 套的极限偏差计算:
套齿槽宽的最小尺寸(综合通端量规)emin=d·π/2z+EI,
按单要素测量时套齿槽宽的最小尺寸 emin1=d·π/2z+EI1,其中 EI1=EI+(T-Ts),
套齿槽宽的最大尺寸(止端量规)emax=d·π/2z+ES,其中 ES=EI+Ts。
2.2. 轴的极限偏差计算:
轴齿厚的最大尺寸(综合通端量规)smax=d·π/2z+es,
按单要素测量时轴齿厚的最大尺寸 smax1=d·π/2z+es1,其中 es1=es-(T-Ts),
轴齿厚的最小尺寸(止端量规)smin=d·π/2z+ei,其中 ei=es-Ts。
3. 单要素测量检验尺寸的计算
由于花键连接不可能在没有形状偏差的情况下制造,通端极限按泰勒原则用综合量规进行检验。
形状和位置偏差的影响由总公差 T 加以考虑。对于没有综合量规的情况,建议采用单要素测量的公差 Ts(或通端极限尺寸)。
单要素测量公差 Ts 的数值(或通端极限的位置)取决于制造精度。T:Ts 的比值取为 1.6,推荐用于中等制造精度。套齿槽宽和轴齿厚宜按检验尺寸 M 和 m 确定。由于测量面靠近曲率半径或齿顶边缘,公法线长度测量不够可靠,因此应优先采用滚柱测量法。
与被测量的止端和通端极限相对应的极限偏差,借助偏差系数ξ按齿槽宽和齿厚的极限偏差计算得出,
公法线长度的偏差借助系数ξW 计算得出。
量规制造所需的、与被测量通端极限相对应的极限偏差,不借助偏差系数计算,而是按适用于齿轮传动的公式计算。
4. 单要素测量极限偏差计算示例
按第 2 节给出的计算公式,可确定所给定精度等级和基本偏差下齿槽宽和齿厚的所有极限偏差。
