ANSI B92.1-1970 SAE花键标准

现代农业2019年7期综合探讨浅析常用渐开线花键标准区别及其应用吴坤(山东常林机械集团股份有限公司,山东临沂276715)[摘要]随着我国与世界联系的日益频繁与深入,进口产品的流通更为广泛,在工程机械和农业机械行业尤为突出,以至各种标准在国内极为常见,以博士力士乐的进口件采用DIN花键标准,日本进口产品采用JIS的花键标准以及美国采用的ANSI、SAE标准等。

以上标准跟我国采用的GB还是有不少差异,文章根据各国标准的特点进行介绍,并与我国GB标准进行比较分析,以便予国内人员提供方便。

SAE花键标准简介(doc 5页)_NewLead Variation is the variation of the direction of the spline tooth from its intended direction parallel to the reference axis, also including parallelism and alignment variations (see Fig. 1a). Note: Straight (nonhelical) splines have an infinite lead.导向公差：导向公差是花键的键齿的实际齿线与花键的参考轴线之间的平行度公差，这个公差包括平行度公差和圆周阵列公差（见图Fig.1a）。

注意：直齿花键（非螺旋花键）的导向公差为无穷大。

译者注：这一条解释有待斟酌。

Length of Engagement (Lq) is the axial length of contact between mating splines.结合长度（Lq）：结合长度是两个相互配合的内、外花键之间的接触段的长度。

Machining Tolerance (m) is the permissible variation in actual space width or actual tooth thickness.加工公差（m）：加工公差是花键的实际齿槽宽和实际齿厚的允许的变动量。

译者注：在《GB/T 3478.1-1995 圆柱直齿渐开线花键》中，将加工公差定义为T。

Major Circle is the circle formed by the outermost surface of the spline. It is the outside circle (tooth tip circle) of the external spline or the root circle of the internal spline.大圆：大圆是花键的最大齿形面的包络圆。

ansi b92.1a-1976花键规格
ANSI B92.1A-1976是一项关于花键规格的标准，它规定了花键的几何尺寸以及制造和设计要求等方面的要求。

这项标准对于机械制造和设计行业非常重要，下面我们来详细了解一下。

一、花键的定义
花键是一种用于固定轴和销等旋转件的机械零件，通常采用直角槽形状，由内联花键槽和外侧花键零件两部分组成。

二、花键的几何尺寸
ANSI B92.1A-1976规定了花键的几何尺寸，包括内径、外径、长度、圆角半径等等。

这些尺寸的严格规范确定了花键的制作标准，确保了花键与配合件的完美匹配。

三、花键的制造和设计要求
除了尺寸规定，ANSI B92.1A-1976还对花键的制造和设计要求做出了详细规定。

其中包括：
1. 材料：花键应该采用高强度的合金钢或不锈钢，并具有足够的刚性和韧性。

2. 表面处理：花键应该进行表面硬化处理，提高其硬度和耐磨性。

3. 安装标准：花键应该按照设计要求与轴配合，确保其准确而牢固地固定在轴上。

4. 承受负载能力：花键应该满足其设计要求下的承受负载能力，确保其能够承受应力和压力。

浅析常用渐开线花键标准区别及其应用作者：吴坤来源：《现代农业·汉文版》 2019年第7期吴坤（山东常林机械集团股份有限公司，山东临沂 276715）[摘要] 随着我国与世界联系的日益频繁与深入，进口产品的流通更为广泛，在工程机械和农业机械行业尤为突出，以至各种标准在国内极为常见，以博士力士乐的进口件采用DIN花键标准，日本进口产品采用JIS的花键标准以及美国采用的ANSI、SAE标准等。

以上标准跟我国采用的GB还是有不少差异，文章根据各国标准的特点进行介绍，并与我国GB标准进行比较分析，以便予国内人员提供方便。

[关键词] 渐开线；花键；特点；区别中图分类号：TH1314文献标识码：B文章编号：１００８－０７０８（2019）07-100-02在农业机械、工程机械设备中，渐开线花键的使用十分普遍，然而一些核心部件还依赖国外进口在这错综复杂的进口设备中，所采用的渐开线花键标准也是各不相同，这也给国内的行业人员造成很大的困扰，这琳琅满目的各国标标准到底有何异同，下面简单介绍以下各国渐开线花键标准的特点及其应用。

1 常用渐开线花键标准的特点1.1 常用渐开线花键标准的基本参数在农业机械、工程机械中，常用的渐开线花键多取用以下几种标准，这几种标准的原理是相同的，仅仅侧重点不同。

基本参数的区别详见表1。

常用的渐开线花键标准包括四种不同的标准压力角：20°压力角、30°压力角、37.5°压力角和45°压力角。

我国国标GB3478.1与国际ISO4156标准一致，常用30°的标准压力角，其它压力角在特殊场合也会使用。

在花键的加工时采用零变位，公差采用4、5、6、7四个等级。

一般取公差5级，其它等级与公差5级的倍数关系为:Class4=0.71，Class5=1，Class6=1.4，Class7=2.0；德标DIN5480花键是基于基准直径的一种渐开线花键，因齿数模数的不同而影响变位系数的变化，并且它的公差等级比较多（有8种），选用时也更加精准，其9级相当于GB的5级公差，DIN5480甚至将花键的加工方法也考虑在内，根据加工方法的不同选用不同的系数（详见表1）。
