din5480渐开线花键标准

din5480渐开线花键标准DIN5480渐开线花键标准。

DIN5480渐开线花键是一种常见的机械连接元件，广泛应用于工程机械、汽车、航空航天等领域。

它具有传递大扭矩、高传动效率和稳定性好等特点，因此备受工程师和设计师的青睐。

本文将对DIN5480渐开线花键标准进行详细介绍，希望能为相关领域的从业人员提供一些参考和帮助。

首先，我们需要了解渐开线花键的基本结构。

渐开线花键是一种带有渐开线齿廓的轴向连接元件，其齿廓具有一定的曲线特性，能够在传递大扭矩的同时减小齿面载荷集中，提高传动效率和使用寿命。

在DIN5480标准中，花键的齿廓参数、尺寸公差、材料要求等都有详细规定，以确保其在不同工况下的可靠性和稳定性。

其次，我们需要了解DIN5480渐开线花键的标准规范。

DIN5480标准是德国标准化协会发布的一项机械传动元件标准，其中包括了渐开线花键的设计、制造、安装和使用等方面的规定。

在标准中，对于花键的齿廓参数、齿形公差、齿顶间隙、齿根间隙、齿槽等都有详细的规定，以确保花键在不同设备中的互换性和可靠性。

此外，DIN5480渐开线花键的应用也需要遵循一定的原则。

在实际工程中，我们需要根据具体的传动要求和工作环境来选择合适的花键型号和尺寸。

同时，在安装和使用过程中，需要严格按照标准规定的工艺要求进行操作，以确保花键的传动效率和安全可靠性。

总的来说，DIN5480渐开线花键标准是机械传动领域中非常重要的一部分，它为工程师和设计师提供了一种高效、可靠的机械连接方案。

通过本文的介绍，希望能够对相关领域的从业人员有所帮助，同时也希望大家能够在实际工程中充分发挥渐开线花键的优势，为工程机械和汽车等设备的性能提升和可靠运行做出贡献。

渐开线花键的联接画法
用剖视图表示花键联接时，其联接部分按外花键绘制。
花键联接时，外花键的小径等，应用细实线画出，如图中红线所示。
后面的内容有点儿
深！
三、渐开线花键的标注
花键的标注有两种：标记标注法和一般尺寸标注法。渐开线花键多采用标记标注法。在有关图样和技术文件中，需要标记时，应符合下列规定：
外花键：D=80mm，Db=69.28mm，Dee=84mm，Die= 74mm 内花键：Dei=86mm，Dii= 76mm
30°平齿根（标记：30P）
m=4mm，z=20，αD=30°圆齿根渐开线内、外花键画法
外花键：D=80mm，Db=69.28mm，Dee=84mm，Die= 72.8mm 内花键：Dei=87.2mm，Dii= 76mm
db=84.6mm，齿顶圆直径da=96mm，齿根圆直径df =82.5mm。
国家标准没让你这样画齿轮！那么，这样画的意义何在？
意义就是画画这种没什么用的立体图，玩玩！上当了吧？怒火中烧了吧？ TMD前面学了半天，你现在才告诉人家“玩玩”！别……别急着骂，还是有一点小用场滴。请往后看——

JIS D2001-1959 汽车用渐开线花键(中文版)

w ww .b zf xw .c om日产汽车类渐开线花键的计算1985年以来我港从日本引进了多种类型的高效流动机械，在进口机械的维修和配件制造工作中，经常遇到渐开线花键的测绘工作。

由于缺乏这方面的技术标准和资料，给测绘工作造成很大困难。

为了解决这一难题，下面扼要介绍JISD2001日本汽车工业用渐开线标准的内容，供从事这一领域工作的技术人员参考。

一、基本参数和计算方法1.基本参数(1)模数m:采用以下三个系列共15种模数(单位:毫米)(2)齿数Z:从6到40个(3)位移量x 和压力角α:位移量X 一般为0.8m ，极少采用0.6m ，0.633m ，0.9m ，0.967m 。

分度圆上的压力角α通常为20°。

(4)基本齿形:图1所示为花键轴的基本齿形w ww .b zf xw .c om2.基本计算公式(1)公称直径:当x=0.8时，d=(Z+2)m当x ≠0.8时，d=(Z+2x+0.4)m(2)孔的外径:①齿形定心和插孔时，D 1=d+0.3m②齿形定心拉孔和外径定心时D 2=d (3)轴的外径:①齿形定心时，d 1=d-0.2m②外径定心时，d 2=d(4)孔的内径:D k =d-2m ， (5)轴的内径:dr=d-2.4m ， (6)分度圆直径:d o =zm ， (7)分度圆上的压力角:αo =20° (8)基圆直径:d j =d o cos α。

(9)周节:t o =πm. (10)基节:t j =t o cos α。

w w w .b zf xw .c o m式中:α′1——轴用量棒中心压力角。

U——测轴跨棒距用量棒直径。

见图2②孔的跨棒距尺寸a 1——孔用量棒中心压力角。

式中:V——测孔跨棒距用量棒直径，见图2，u 和V 数值从表1可查得。

w ww .b z f xw .c om图2中:V 1——量棒削去后的尺寸，V 1可从表1中查出。

当m=1时的跨棒距可从表1中直接查得，将该数值乘以模数即是量值的公称尺寸。

SPLINESANDSERRATIONSA splined shaft is one having a series of parallel keys formed integrally with the shaft and mating with corresponding grooves cut in a hub or fitting; this arrangement is in contrast to a shaft having a series of keys or feathers fitted into slots cut into the shaft. The latter construction weakens the shaft to a considerable degree because of the slots cut into it and consequently, reduces its torque-transmitting capacity.花键轴是一种具有“一系列相互平行的齿、并且齿与轴整体成型”的轴，它与在轮毂上或者装配体上开的键槽相配合。

这种装置与“在轴上开槽并且与一组销子或者楔键相配合”的结构相反。

后者的结构由于在轴上开槽大大降低了轴（的强度），降低了传递扭矩的能力。

Splined shafts are most generally used in three types of applications: 1 ) for coupling shafts when relatively heavy torques are to be transmitted without slippage; 2) for transmitting power to slidably-mounted or permanently-fixed gears, pulleys, and other rotating members; and 3) for attaching parts that may require removal for indexing or change in angular position.花键轴主要用在以下三种情况：1）需要在无滑动的联轴器上传递大的扭矩；2）用于向“可滑动的装配组件”或者“固定装配的齿轮组或滑轮副”传递动力，3）用于“要求指定滑移量或转角位置”的配件上。
