花键轴中不同类型的花键

A splined shaft is a machine component with internal and external splines. The splines are formed in four different ways: Involute, Parallel, Serrated, and Ball. You can learn more about each type of spline in this article. When choosing a splined shaft, be sure to choose the right one for your application. Read on to learn about the different types of splines and how they affect the shaft’s performance.

渐开线花键

渐开线花键用于固定和延长机械组件。它们是光滑的内弯槽，可防止运转过程中分离。带有渐开线花键的轴通常比轴本身更长。这一特性允许更大的轴向移动距离。这对于许多应用都非常有利，尤其是在变速箱中。
渐开线花键是一种异形花键，类似于平行花键。它呈一定角度，由形成螺旋状齿纹的齿组成，可实现直线和旋转运动。与其他花键的区别在于其侧面的锯齿。此外，它的顶部是平的。渐开线花键是联轴器和其他需要角度运动的应用的理想选择。
渐开线花键也称为渐开线齿，因其形状而得名。它们顶部平坦，侧面弯曲。这些齿可以是内齿，也可以是外齿。因此，渐开线花键能提供更大的接触面积，有助于减少应力和疲劳。无论形状如何，渐开线花键通常都易于加工和装配。
渐开线花键是用于花键轴的一种花键类型。根据直径的不同，这些花键有不同的名称。例如，32齿外花键、2500齿模数和30度压力角的花键可以这样命名。内花键（例如圆角根花键）的命名则用于描述花键轴的直径。
花键的有效齿厚取决于键槽的数量和花键的类型。花键轴中的渐开线花键应设计成在连接过程中啮合25%至50%的齿。渐开线花键应能承受载荷而不发生裂纹。

平行花键

Parallel splines are formed on a splined shaft by putting one or more teeth into another. The male spline is positioned at the center of the female spline. The teeth of the male spline are also parallel to the shaft axis, but a common misalignment causes the splines to roll and tilt. This is common in many industrial applications, and there are a number of ways to improve the performance of splines.
通常，平行花键用于减少旋转部件中的摩擦。花键轴上的花键端面比内径窄，因此更容易磨损。这种花键广泛应用于机械等行业，并且在传递扭矩时效率更高。
轴上最常见的是渐开线花键。它们的齿间距相等，因此不易因疲劳而开裂。它们也通常易于切割和装配。然而，它们并非最佳花键类型。在决定使用哪种花键之前，了解平行花键和渐开线花键之间的区别至关重要。
花键式花键和渐开线花键的区别在于槽的尺寸。渐开线花键通常比平行花键的槽更大。这类花键能为齿轮齿提供更大的扭矩，并降低运转过程中的应力。它们也更耐用，使用寿命更长。由于它们常用于农用机械，因此在这类应用中至关重要。

锯齿状花键

锯齿花键轴具有诸多优势。这种轴的调节性极佳。其大量的齿数使其能够承受较大的扭矩，而较窄的齿宽则使其能够进行更精确的调节。这些特性使得这种轴成为精度要求极高的应用的理想选择。以下列出了这种轴的部分优点。这些优点只是其众多优势中的一部分。了解更多关于这种轴的信息。
滚齿加工工艺成本低廉且精度高，适用于外花键轴，但不适用于内花键轴。该工艺可在轴上形成同步形状，从而缩短制造周期并稳定花键和螺纹之间的相对相位。它使用砂轮对轴进行成形。CZPT制造公司备有大量锯齿花键轴库存。
锯齿花键轴的齿设计用于与轮毂在整个轴圆周上啮合。轴上的齿均匀分布在花键周围，从而在整个轴长上形成多齿接触点。这些分析的结果通常令人满意。但也存在一些局限性。首先，应仔细选择锯齿花键轴的花键。如果应用需要进行大规模分析，则可能需要修改设计。
锯齿状花键轴的花键除了用于其他用途外，还可用于将扭矩传递给其他设备。它们还可以起到防旋转装置和线性导轨的作用。花键轴的功能取决于其设计和类型。在汽车工业中，它们被广泛应用于车辆、航空航天、工程机械以及许多其他行业。

球头花键

The invention relates to a ball-spinned shaft. The shaft comprises a plurality of balls that are arranged in a series and are operatively coupled to a load path section. The balls are capable of rolling endlessly along the path. This invention also relates to a ball bearing. Here, a ball bearing is one of the many types of gears. The following discussion describes the features of a ball bearing.
A ball-splined shaft assembly comprises a shaft with at least one ball-spline groove and a plurality of circumferential step grooves. The shaft is held in a first holding means that extends longitudinally and is rotatably held by a second holding means. Both the shaft and the first holding means are driven relative to one another by a first driving means. It is possible to manufacture a ball-splined shaft in a variety of ways.
滚珠花键轴的特点是其螺母内装有循环滚珠。滚珠花键螺母在这些凹槽内滑动，从而实现直线运动并防止旋转。带有循环滚珠螺母的花键轴也可以实现旋转运动。此外，滚珠花键轴的承载能力也高于滚珠衬套。因此，滚珠花键是许多应用的理想选择。
In this invention, a pair of ball-spinned shafts are housed in a box under a carrier device 40. Each of the two shafts extends along a longitudinal line of arm 50. One end of each shaft is supported rotatably by a slide block 56. The slide block also has a support arm 58 that supports the center arm 50 in a cantilever fashion.

扇形禁入规

止规是一种用于检查花键轴尺寸是否过大的工具。它无需拆卸轴即可有效确定花键轴的尺寸是否过大。止规可测量外花键和锯齿。其尺寸范围从 19 毫米到 130 毫米，轮廓长度为 25 毫米。
The sector no-go gage has two groups of diametrally opposed teeth. The space between them is manufactured to a maximum space width and the tooth thickness must be within a predetermined tolerance. This gage would be out of tolerance if the splines were measured with a pin. The dimensions of this splined shaft can be found in the respective ANSI or DIN standards.
通止规用于最终检验螺纹节圆直径，也适用于花键轴和螺纹螺母。螺钉的螺纹必须与通止规头部的轮廓相匹配，以避免出现无法通过的情况。高质量的通止规无可替代，是任何花键轴和紧固件制造商的必备工具。
通规可以检测齿厚的变化。它符合 ISO17025 标准，并比普通通止规具有诸多优势。它还能直观地显示花键轴的厚度。当齿厚匹配时，即可认为该轴已准备好安装。这是一个至关重要的过程。在某些情况下，无法精确确定花键轴的长度。
The 45-degree pressure angle is most commonly used for axles and torque-delivering members. This pressure angle is the most economical in terms of tool life, but the splines will not roll neatly like a 30 degree angle. The 45-degree spline is more likely to fall off larger than the other two. Oftentimes, it will also have a crowned look. The 37.5 degree pressure angle is a compromise between the other two pressure angles. It is often used when the splined shaft material is harder than usual.
