一、四列圆锥滚子轴承内圈与辊颈的配合一般是带间隙的，安装时先将轴承装入轴承箱，然后把轴承箱装入轴颈。二、四列圆锥滚子轴承外圈与轴承箱孔亦采用动配合，先将外圈A装入轴承箱。出厂时在外圈、内圈以及内外隔圈均印有{HotTag}，安装时必须按字符符号的排列顺序依次装入轴承箱。不可任意互换，以防止轴承游隙的改变。三、全部零件都装入轴承箱后，将内圈与内隔圈、外圈与外隔圈轴向靠紧。四、测量外圈端面与轴承箱盖板之间的缝隙宽度，以确定相应密封垫片的厚度。

1、比如有一根轴需要在两端安装两个这样的轴承,2、安装的时候,滚子倾斜方向有规定么?是不是一定要和下图一样3、轴承内外圈滚子接触面是圆锥面还是

一、滚动轴承的基本代号轴承型式代号：0双列斜角滚珠轴承1自动调心滚珠轴承2球面滚子轴承和球面滚子止推轴承3锥型滚子轴承4双列深沟滚珠轴承5止推滚珠轴承6单列深沟滚珠轴承7单列斜角滚珠轴承8圆柱滚子止推轴承N圆筒型滚子轴承QJ 四点接触滚珠轴承二、轴承的分类及优缺点轴承可分为：滚动轴承和滑动轴承两大类。（一）滚动轴承与滑动轴承相比，各自的优缺点：滚动轴承的优点 : 1．滚动轴承的摩擦系数比滑动轴承小,传动效率高。一般滑动轴承的摩擦系数为0.08-0.12,而滚动轴承的摩擦系数仅为0.001-0.005; 2．滚动轴承已实现标准化、系列化、通用化,适于大批量生产和供应，使用和维修十分方便； 3．滚动轴承用轴承钢*,并经过热处理,因此,滚动轴承不仅具有较高的机械性能和较长的使用寿命,而且可以节省*滑动轴承所用的价格较为昂贵的有色金属; 4．滚动轴承内部间隙很小,各零件的*精度较高,因此,运转精度较高。同时,可以通过预加负荷的方法使轴承的刚性增加。这对于精密机械是非常重要的; 5．某些滚动轴承可同时承受径向负荷和轴向负荷,因此,可以简化轴承支座的结构; 6．由于滚动轴承传动效率高,发热量少,因此,可以减少润滑油的消耗,润滑维护较为省事;7．滚动轴承可以方便地应用于空间任何方位的铀上。但是,一切事物都是一分为二的,滚动轴承也有一定的缺点,主要是： 1．滚动轴承承受负荷的能力比同样体积的滑动轴承小得多,因此,滚动轴承的径向尺寸大。所以,在承受大负荷的场合和要求径向尺寸小、结构要求紧凑的场合〈如内燃机曲轴轴承),多采用滑动轴承； 2．滚动轴承振动和噪声较大,特别是在使用后期尤为显著,因此,对精密度要求很高、又不许有振动的场合,滚动轴承难于胜任,一般选用滑动轴承的效果更佳 3．滚动轴承对金属屑等异物特别敏感,轴承内一旦进入异物,就会产生断续地较大振动和噪声,亦会引起早期损坏。此外,滚动轴承因金属夹杂质等也易发生早期损坏的可能性。即使不发生早期损坏,滚动轴承的寿命也有一定的限度。总之,滚动轴承的寿命较滑动轴承短些。可是,滚动轴承与滑动轴承相比较,各有优缺点,各占有一定的适用场合,因此,两者不能完全互相取代,但是,由于滚动轴承的突出优点，目前,滚动轴承已发展成为机械的主要支承型式,应用愈来愈广泛。

一般选用圆锥滚子轴承，面对面和背靠背都可以，游隙大小要根据你选择的轴承大小和机构要求的传动精度选定游隙组别确定！至于调整方法可以用压紧回松的办法实现！

予你意 08-01 05:27

圆筒滚子轴承安装方法，主要上要留意你的轴承尺寸以及游间隙，因为一般的问题主要出现在轴间隔所产生的缝隙，以及不可以随意的互换，以及压紧回松这种方法来调整。
