如何计算花键联轴器的刚度、定心力、磨损和疲劳失效

花键联轴器有多种类型。这些联轴器具有几个重要的特性，包括：刚度、渐开线花键、不对中性、磨损和疲劳失效。要了解这些特性与花键联轴器之间的关系，请阅读本文。本文将为您提供必要的知识，帮助您确定哪种类型的联轴器最适合您的需求。需要注意的是，花键联轴器通常呈球形，由钢制成。

渐开线花键

An effective side interference condition minimizes gear misalignment. When two splines are coupled with no spline misalignment, the maximum tensile root stress shifts to the left by five mm. A linear lead variation, which results from multiple connections along the length of the spline contact, increases the effective clearance or interference by a given percentage. This type of misalignment is undesirable for coupling high-speed equipment.
Involute splines are often used in gearboxes. These splines transmit high torque, and are better able to distribute load among multiple teeth throughout the coupling circumference. The involute profile and lead errors are related to the spacing between spline teeth and keyways. For coupling applications, industry practices use splines with 25 to fifty-percent of spline teeth engaged. This load distribution is more uniform than that of conventional single-key couplings.
To determine the optimal tooth engagement for an involved spline coupling, Xiangzhen Xue and colleagues used a computer model to simulate the stress applied to the splines. The results from this study showed that a “permissible” Ruiz parameter should be used in coupling. By predicting the amount of wear and tear on a crowned spline, the researchers could accurately predict how much damage the components will sustain during the coupling process.
确定渐开线花键最佳压力角的方法有多种。渐开线花键通常使用30度压力角进行测量。与齿轮类似，渐开线花键通常通过销钉测量法进行测试。该方法是将特定尺寸的金属丝插入齿轮齿间，并测量金属丝之间的距离。这种方法可以判断齿轮的齿廓是否符合要求。
The spline system shown in Figure 1 illustrates a vibration model. This simulation allows the user to understand how involute splines are used in coupling. The vibration model shows four concentrated mass blocks that represent the prime mover, the internal spline, and the load. It is important to note that the meshing deformation function represents the forces acting on these three components.

耦合刚度

The calculation of stiffness of a spline coupling involves the measurement of its tooth engagement. In the following, we analyze the stiffness of a spline coupling with various types of teeth using two different methods. Direct inversion and blockwise inversion both reduce CPU time for stiffness calculation. However, they require evaluation submatrices. Here, we discuss the differences between these two methods.
第二部分推导了样条联轴器的解析模型。第三部分详细解释了计算过程。随后，我们将该模型与有限元方法进行了对比验证。最后，我们讨论了刚度非线性对转子动力学的影响。最后，我们分析了各种方法的优缺点。我们提出了一种简单而有效的样条联轴器横向刚度估算方法。
样条联轴器的数值计算基于半解析样条载荷分布模型。该方法涉及精细的接触网格，并在每次迭代中更新柔度矩阵，因此计算时间较长。此外，该方法难以应用于转子的动力学分析。该方法存在一定的局限性，仅应在对样条联轴器进行全面研究后使用。
啮合力是指未对准的花键联轴器产生的力。它与花键厚度和转子的传递扭矩有关，也与动态振动位移有关。啮合力分析的结果如图7、图8和图9所示。
本文旨在分析错位花键联轴器的刚度。尽管以往研究结果较为准确，但仍存在一些问题。例如，花键错位可能导致接触损伤。本文旨在研究错位花键联轴器的相关问题，并提出一种用于估算花键连接中接触压力的解析方法。此外，我们还将本文结果与纯数值方法的结果进行了比较。

错位

为了确定定心力，必须知道有效压力角。利用有效压力角，基于最大轴向和径向载荷以及更新后的达德利不对中系数计算定心力。定心力是摩擦力能够传递的最大轴向力。计算中还包含了几个已发表的不对中系数。本文提出了一种考虑凸轮效应对法向力影响的新方法。
这种新方法可以将花键连接处的刚度积分，从而获得适用于扭转振动分析的整体刚度。此外，还可以计算给定不对中程度下的轴承刚度，从而精确估算轴承尺寸。建议始终检查轴承刚度，以确保其尺寸和对中正确。
花键联轴器的错位会导致磨损甚至失效。这是由于齿形轮廓未正确对齐造成的。由于齿在整个渐开线轮廓上都保持接触，因此这个问题常常被忽视。这导致载荷沿接触线分布不均匀。因此，必须考虑错位对花键联轴器齿接触力的影响。
图2中，阳花键的中心与阴花键的中心重合，啮合距离也相同。因此，啮合力曲线会随动态振动位移而变化。在实施花键联轴器之前，必须了解其参数。本文提出了花键联轴器的错位模型及其相关参数。
利用自制的花键联轴器试验台，研究了不对中对花键联轴器的影响。与典型的花键联轴器不同，不对中会导致花键联轴器齿面特定位置发生微动磨损。这是此类联轴器失效的主要原因。

磨损和疲劳失效

花键联轴器因磨损和疲劳而失效，取决于齿磨损和轴不对中首次出现的时间。标准设计方法并未考虑磨损损伤，对疲劳寿命的评估也存在较大误差。本文开展了实验研究，旨在评估花键联轴器的磨损和疲劳损伤。实验在专用试验台和连接至标准疲劳试验机的特殊装置上进行。通过改变扭矩、不对中角和轴向距离等工作参数，测量了疲劳损伤。此外，还评估了超尺寸效应。
During fatigue and wear, mechanical sliding takes place between the external and internal splines and results in catastrophic failure. The lack of literature on the wear and fatigue of spline couplings in aero-engines may be due to the lack of data on the coupling’s application. Wear and fatigue failure in splines depends on a number of factors, including the material pair, geometry, and lubrication conditions.
对花键联轴器的分析表明，尺寸过大是一种常见现象，会导致系统出现各种损伤。主要损伤包括磨损、微动磨损、腐蚀和齿疲劳。在工业应用中也观察到了噪声问题。然而，评估花键联轴器的接触行为十分困难，数值模拟常常受到特定代码和边界元方法的限制。
花键齿轮联轴器的失效是由疲劳引起的，断裂始于键槽底部圆角处。键槽和花键的过载超过了其屈服强度，花键齿轮齿部出现了明显的屈服现象。非标合金钢的断裂环具有尖锐的圆角，这是一个显著的应力集中点。
Several components were studied to determine their life span. These components include the spline shaft, the sealing bolt, and the graphite ring. Each of these components has its own set of design parameters. However, there are similarities in the distributions of these components. Wear and fatigue failure of spline couplings can be attributed to a combination of the three factors. A failure mode is often defined as a non-linear distribution of stresses and strains.
