滚动轴承
滚动轴承一般是由内圈2、外圈1、滚动体3和保持架4如图2-1
图2-1滚动轴承结构 内圈装在轴上，外圈装在机座或零件的轴承孔内。内外圈上有 滚道，当内外圈相对旋转时，滚动体将沿着滚道滚动。保持架 的作用是把滚动体均匀地隔开。
滚动轴承具有摩擦阻力小、启动灵敏、效率高、润滑简便和易 于互换等优点，所以获得广泛的应用。它的缺点是抗冲击能力较差， 高速时出现噪声，工作寿命也不及液体摩擦的滑动轴承。 （1）深沟球轴承，类型代号6，主要承受径向载荷，同时也可承受 一定量的轴向载荷。当转速很高而轴向载荷不太大时,可代替推力球 轴承受纯轴向载荷。 （2）圆柱滚子轴承，类型代号N，能承受较大的径向载荷，不能承 受轴向载荷。因系线接触，内外圈只允许有极小的相对偏转。 （3）调心滚子轴承： 类型代号2，其结构特点是滚动体为双列鼓形 滚子,外圈滚道是以轴承中心为中心的球面。故能自动调心 , 能承受 很大的径向载荷和少量的轴向载荷, 抗振动,冲击。

起重机车轮组滚动轴承的计算
起重机车轮组滚动轴承的计算通用桥门式起重机系列大、小车车轮组（含水平轮）所用的轴承有三个系列，调心球轴承、单列圆锥滚子轴承和双列调心滚子轴承，轴承代号及标准号见下表：银起厂桥门吊系列大、小车轮组（含水平轮）采用的轴承型号规格参数见下表：注：1.有轴向载荷的起重机大车轮采用双“单列圆锥滚子轴承”且制造安装均能保证载荷均布时，稳定动负荷并不是单列轴承的两倍，对线接触是27/9=1.71倍。
2.两套向心球轴承或向心滚子轴承并排安装且作为整体运转时，计算其额定动载荷时，应按一套双列轴承来考虑。
太重集团“工厂标准”-主（从）动车轮TZQ7163/4-1989，科尼公司1998系列计算书中给出的起重机车轮组所采用的轴承型号规格见下表：近年来，由于单列圆锥滚子轴承（含为避免会产生的附加轴向力而成对配制时）轴向游隙的大小对能否良好工作影响很大，装配及使用过程中又不便调整，故寿命较差，已为双列调心滚子轴承所代替，这可从太重和科尼的产品得到证实。
本次系列设计，车轮组使用双列调心滚子轴承（GB288-1994），按手册推荐“应优先选用经结构优化设计的类别”的原则，全部选用22200C/W33或22300C/W33型（C-经设计改进,加强型；W33-轴承外圈上有三个油槽和3个油孔）。
本次设计采用的大小车轮轴承见下表：一．滚动轴承的选用程序1．滚动轴承按照需要确定类型后，应该按实际承受的载荷计算出当量动载荷，再根据所需要的寿命计算出额定动载荷C和额定静载荷C O，按照不大于轴承性能表中的额定值查选型号规格；2. 选择轴承的精度、游隙、与轴及轮毂的配合，润滑剂及润滑方法3. 轴承的密封及轴向的固定二. 按标准推荐的方法计算选择轴承的型号规格车轮组轴承属于低速旋转的轴承，宜按额定动载荷和额定静载荷的计算值，取其中较大者查滚动轴承性能表选择轴承。

圆锥滚子轴承游隙设定的方法
设定合适的轴承游隙可以增加系统的刚度，例如，合适的游 隙可以让齿轮更好地接触，延长齿轮的寿命
轴承内圈和外圈可以分离，更容易安装
轴承的游隙在装配机器时设定，因此可以接受更宽的轴和轴 承座的公差范围
可以通过多种方法来快捷地设定圆锥滚子轴承的游隙。可 以手动设定游隙，预设游隙或自动设定游隙。五种常用的自动 设定游隙的方法（即SETRIGHTTM、ACRO-SETTM、PROJECTASETTM、TORQUE-SETTM 和 CLAMP-SETTM），每一种都有很多实 施方式、注意事项和优势。见表 1。
某些应用的安装游隙会被设定成预紧以提高承受高应力部 件的刚度或进行轴向定位，否则这些部件就会受到过度挠曲和 偏心的影响。
必须避免工作状态下的过度预紧，否则轴承的疲劳寿命会 显著缩短。另外，运行时过度预紧会产生大量热量，可能导致 润滑问题和轴承的过早损坏。
承载区是对滚道承载圆弧的物理计量，直接反应了承担载 荷的滚子数量。对于单列圆锥滚子轴承，最大寿命对应的承载 区大约为 225 度。图 2 用图示说明了轴承在（悬臂）齿轮轴上的 L10 寿命和工作游隙之间的关系。
对于复杂的、大型的或大批量生产的应用，手动设定游隙可 能太麻烦，不精确，不可靠或太费时。铁姆肯公司设计出了预设 游隙轴承组件和自动游隙设定方法，作为手动设定游隙的替代 方案。
6 圆锥滚子轴承游隙设定的方法
预设游隙轴承组件
预设游隙轴承组件
典型的预设游隙轴承组件的应用
很多应用使用或需要双列或紧密连接配对的轴承组件。这取 决于机器的设计和运行特点（如热增长的影响、高载荷等）。为 便于设定这种情况下的轴承游隙，我们经常使用预设游隙轴承 组件。预设游隙轴承组件具有各种形式。但大多数一般被称为带 隔圈轴承（图 4）。大多数预设游隙轴承在制造和供应时都带有隔 圈。隔圈根据轴承进行配磨定制，用于控制内部间隙（参考类型 2S 和 TDI）。因此，这些定制或“配磨”的隔圈无法与其他轴承 组装件互换使用。有一些预设游隙组件，如类型 SR 或 TNA，可 以允许使用可互换的隔圈和/或轴承部件。设计这些可互换组装 件部件的目的是为了更严格地控制影响轴承游隙的重要公差，因 此，这些部件可以随机选择使用。
