SPLINES AND SERRATIONSA 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。

SAE花键标准简介

ANSI B92.1-1970 SAE花键标准INVOLUTE SPLINES渐开线花键Form Circle is the circle which defines the deepest points of involute form control of the tooth profile. This circle along with the tooth tip circle (or start of chamfer circle) determines the limits of tooth profile requiring control. It is located near the major circle on the internal spline and near the minor circle on the external spline.渐开线终止圆：渐开线终止圆是用于操纵齿廓上渐开线的极限距离的圆。

渐开线终止圆与齿顶圆（或者修缘线的起点所在的圆）共同限制了所要求操纵的渐开线齿廓的范围。

渐开线终止圆的位置靠近内花键的大圆（齿根圆）或者外花键的小圆（齿根圆）。

译者注：这段话的意思是：只有在渐开线终止圆与齿顶圆（或者修缘线的起点所在的圆）之间的花键的齿形为渐开线齿形，其余部分不一定按照渐开线成形。

译者注2：在《GB/T 3478.1-1995 圆柱直齿渐开线花键》中，将Form Cycle定义为两个圆：内花键的渐开线终止圆和外花键的渐开线起始圆。

而在本标准中，将这两个圆统称为Form Cycle，译者将Form Cycle翻译为渐开线终止圆。

Form Clearance (c F) is the radial depth of involute profile beyond the depth of engagement with the mating part. It allows for looseness between mating splines and for eccentricities between the minor circle (internal), the major circle (external), and their respective pitch circles.齿形裕度：齿形裕度（c F）是相互配合的内、外花键的渐开线齿廓在径向方向上的间隙。

sae常用花键参数

sae常用花键参数【原创版】目录1.SAE 常用花键参数概述2.SAE 常用花键参数的分类3.SAE 常用花键参数的具体内容4.SAE 常用花键参数的应用场景5.总结正文【1.SAE 常用花键参数概述】SAE（Society of Automotive Engineers，汽车工程师协会）常用花键参数是指在汽车工程领域中，用于描述花键连接的各个尺寸和参数的标准化规范。

花键连接在汽车行业中应用广泛，例如用于连接变速器和驱动轴等部件。

SAE 常用花键参数的规范有助于保证这些连接的可靠性和互换性。

【2.SAE 常用花键参数的分类】SAE 常用花键参数主要分为以下几类：- 齿数（Teeth Number）：花键连接中齿轮的数量。

- 齿形（Tooth Form）：花键齿轮的齿廓形状。

- 齿高（Tooth Height）：花键齿轮齿廓的垂直高度。

- 齿根圆（Root Circle）：花键齿轮齿根的圆周。

- 齿顶圆（Tooth Circle）：花键齿轮齿顶的圆周。

- 花键长度（Keyway Length）：花键连接的长度。

【3.SAE 常用花键参数的具体内容】- 齿数：SAE 推荐采用整数齿数，以避免齿数分数化导致的制造和装配困难。

常见的齿数有 12、16、18、20、24 等。

- 齿形：SAE 规定了多种齿形，如矩形齿、渐开线齿、螺旋齿等，以适应不同工况下的传动需求。

- 齿高：齿高的大小影响花键连接的承载能力和使用寿命。

SAE 根据不同的齿形规定了相应的齿高范围。

- 齿根圆和齿顶圆：这两个参数决定了花键齿轮的大小和形状，SAE 规定了相应的尺寸范围以保证齿轮制造和装配的精度。

- 花键长度：花键长度决定了连接部件的传动范围和稳定性。

SAE 根据不同应用场景规定了不同的花键长度。

【4.SAE 常用花键参数的应用场景】SAE 常用花键参数在汽车工程中有广泛的应用，例如：- 变速器和驱动轴连接：花键连接可以传递扭矩，实现变速器和驱动轴之间的可靠连接。

SPLINES AND SERRATIONS（翻译：朱晓峰,浙江，金华）A 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.

粘度范围
为获得最优效率和使用寿命，我们推荐工作粘度（在工作温度时）在下列范围内选择：
νopt = 最佳粘度 16...36 mm2/s
开式回路中针对油箱温度。
粘度极限范围
极限粘度值如下： νmin = 5 mm2/s 短时 (t < 3 min) ，最高允许温度tmax = +115°C下。 νmax = 1600mm2/s, 短时(t < 3 min) ，冷启动(p < 30 bar, n ≤ 1000 rpm, tmin = -40°C)下。请注意，最高允许油液温度115°C即使在局部也不可超过（如轴承区）。轴承区的温度与压力和转速有关，它比平均壳体泄油温度高12K。温度在-40°C和-25°C之间时，需要采取特殊措施。请与我公司联系。有关在低温下使用的详细资料，参见RC 90300-03-B。

美国丹尼逊油泵

T6 系列叶片泵按高强度键设计，因此，在安装或更换该系列泵时，必须使用经热处理的高强度键以保证最长的使用寿命。如果平键需要更换，则代换键的热处理硬度应为： Rc 27~34，键的棱边须倒角 0.75~1 x 45°以适应键槽底边处的圆角。注：泵输入轴与驱动轴之间的同轴度偏差应在上述对花键轴规定的范围内。
本系列产品原始设计为采用轴间扭矩驱动，传动轴不可承受轴向和侧向负载。详情请见有关专门章节。初始启动时最好以最低转速和最低压力运转一个短时，使液压泵符合运行条件。此时，若泵的出口配置有溢流阀，请将其调松以将压力降至最低。若有可能，应在系统回路中设置放气点以便排除系统内的空气。在未检查泵的初始运行条件及未对油液排气前，请勿让泵以高转速和高压力运转。
适用的阻燃液压液包括：磷酸脂液、氯化烃液、水乙二醇以及油包水乳化液。使用这些液压液时，本型泵也可在较高的压力下工作，工作液的使用寿命也较长。
适用的工作液粘度范围为：860～10 cSt（对车用型泵为：2000～10 cSt）。允许低温启动和高温运行，平衡式的补偿结构可以对磨损和温度变化进行补偿，即使在高粘度或低温状态下，转子与侧板之间仍然能得到很好的润滑，机械效率仍较高。
