汽车自动变速器用行星齿轮系综合
本文将探讨用于汽车自动变速器的行星齿轮系的合成、应用及成本。阅读完本文后，您或许会想自行研究这项技术。以下是一些相关链接，可供您进一步阅读。这些链接中也包含行星齿轮系在混合动力汽车变速器中的应用案例。让我们先来了解一下行星齿轮系的基本概念。它们效率极高，是传统齿轮系统的理想替代方案。
汽车自动变速器用行星齿轮系的综合
汽车自动变速器的主要目的是保持发动机驱动车轮的平衡。行星齿轮系（EGT）的运动学结构源自这些齿轮系的图表示。综合过程基于一种算法，该算法可生成最多包含十个连杆的合格行星齿轮系。该算法使设计人员能够设计出性能更高、发动机驱动车轮平衡性更好的汽车齿轮系。
本文提出了一种基于MATLAB的行星齿轮传动机构齿轮比优化方法。我们还统计了所有齿轮的齿数。然后，我们估算了所得行星齿轮传动机构的整体速度比。最后，我们通过比较其结构特性，分析了所提出的行星齿轮传动机构在汽车自动变速器中的可行性。
下图所示为一个六连杆行星齿轮系的功能图。每个连杆均用双色图表示。图上的数字代表相应的连杆编号。每个连杆包含多个关节。这使得用户可以为每个行星齿轮系生成不同的配置。不同图上的数字具有不同的含义，双色图也同样如此。
本文下一章将探讨汽车自动变速器用行星齿轮系的综合设计。SAE International 是一个由工程师和技术专家组成的国际组织，其核心专长领域为航空航天和汽车行业。其慈善机构 SAE 基金会支持众多项目和活动，包括大学生设计系列赛、“动感世界”(A World In Motion®) 以及 SAE 基金会的“动感世界”(A World in Motion®) 奖项。
应用程序
行星齿轮系是一种行星齿轮传动装置。它能在很小的空间内实现很大的减速比。在汽车中，行星齿轮系常用于自动变速器。这种齿轮系也广泛应用于起重机和滑轮组。它在机械工程和电气工程领域都有着广泛的应用。与其他类型的齿轮系相比，它可用于高速传动，并且占用空间更小。
行星齿轮系的优点包括结构紧凑、重量轻、功率密度高。然而，它也并非没有缺点。行星齿轮系中的齿轮损耗是由齿轮齿面间的摩擦、润滑油的搅动以及轴承与链轮间的摩擦造成的。这种功率损失被称为潜在功率，以往的研究表明，这种损失非常巨大。
行星齿轮系常用于高速传动，但它体积小巧，适用于多种应用。它可用作高速机架中的差速齿轮、驱动纱管以及织机中的罗珀正向送纱装置。此外，它易于制造，使其成为各种工业环境的理想选择。
行星齿轮系是周转轮系的另一个例子。它由两个齿轮组成，中间有一个内圈，外圈是太阳轮。每个齿轮的安装方式都使得其中心绕着另一个齿轮的内圈旋转。行星齿轮和太阳轮的设计使得它们的节圆不打滑且同步。行星齿轮节圆上有一个点，该点描绘出外摆线。
这种齿轮系统的平均维修时间 (MTTR) 也比其他类型的行星齿轮更低。这类齿轮组的主要缺点是需要大量的轴承。此外，行星齿轮的维护比平行轴齿轮更复杂，这使得它们的监控和维修更加困难。虽然行星齿轮的平均维修时间也低于平行轴齿轮，但它们的轴线可能会略有偏差，导致对中不良或效率下降。
行星齿轮系的另一个例子是汽车的差速器。这些齿轮用于手表、车床和汽车中以传递动力。此外，它们还应用于许多其他领域，包括飞机。它们运行安静且经久耐用，因此是许多应用的理想选择。它们被用于传动装置、纺织机械，甚至航空航天领域。节圆点是齿轮组中两个齿之间的路径。可以通过增大一个齿轮的基圆来增大其轴向节距。
行星齿轮系也称为渐开线齿轮系。每个齿轮的齿数决定了其转速。一个24齿的太阳轮可以驱动一个N齿的行星轮，其传动比为3/2。一个24齿的太阳轮对应一个-3/2的行星轮。因此，行星齿轮系可以为驱动轮提供高扭矩。然而，这种齿轮系在车辆中并不常用。
成本
采用刀具加工而非普通数控铣床加工的行星齿轮成本更低。行星齿轮架应采用铸造工艺制造，并使用配备多把刀具的专用机床进行刀具加工，以便同时切削材料。这种方法广泛应用于工业领域，尤其适用于汽车行业。优质的行星齿轮传动装置具有诸多优势。
例如，行星齿轮系统中，行星绕太阳公转的同时，自身也绕着轴旋转。每个齿轮的最终转速取决于齿数和行星架的转速。行星齿轮的相对转速计算较为复杂，因为必须计算太阳和行星的相对转速。由于太阳在啮合时并非零转速，因此必须计算其相对转速。
为了确定啮合动力传输，行星齿轮必须设计成能够“浮动”。如果切向载荷过低，则载荷分配会减少。行星齿轮必须允许“浮动”，并且还应允许一定的切向载荷和节线速度。这些因素越高，齿轮组的效率就越高。
行星齿轮系由两个或多个沿圆周方向排列的正齿轮组成。这些齿轮的排列方式使得行星齿轮在其固定外齿圈的节圆内滚动。这条曲线称为内摆线。行星齿轮系中，行星齿轮与太阳齿轮啮合的齿轮系称为行星齿轮系。太阳齿轮固定，行星齿轮从动。
行星齿轮系包含多个啮合齿轮。每个齿轮的啮合数量不同，这决定了其转速（RPM）。行星齿轮系通过将输入扭矩传递到啮合齿轮上，可以提高负载施加频率。行星齿轮系由三个齿轮组成：太阳轮、行星轮和内齿圈。太阳轮位于中心，行星轮围绕太阳轮运行。内齿圈有多个齿，这提高了齿轮的转速。
另一种行星齿轮是行星齿轮箱。这种齿轮箱由多个围绕中心轴旋转的齿轮组成。其低矮的设计使其成为空间受限应用中的热门选择。这种齿轮箱用于自动变速器。此外，它还用于许多涉及电动齿轮电机的工业应用。您使用的齿轮箱类型将取决于输入轴和输出轴的转速和扭矩。
